Guide on different types of strainers in pipeline

A pipeline strainer is a device that filters out fines, dirt, and debris from the flow medium. They also protect upstream equipment like compressors, filters, pumps, and traps by trapping any particles that may clog them up. Different strainers exist for various purposes and are made out of various materials. Here we’ll explain some of the more popular ones. Before selecting a strainer, ensure it meets your application needs and fits within the budget. Consider factors like operating pressure range, fluid characteristics, and strainer geometry when making your selection. What Is A Strainer? An industrial strainer is a piece of equipment used to remove debris and solid materials from fluid flowing through it. These devices prevent these pollutants from damaging pumps, compressors, and other crucial equipment within a pipeline system. Industrial strainers come in several varieties, such as simplex, Y (wye), duplex, and automatic. Strainers typically feature a pocket that directs debris into it; however, vertical pipes may also be utilized if the flow is downward. Either way, make sure that this pocket points away from any upstream pipework. Types Of Strainers Industrial settings employ a variety of strainers to remove sediment and debris from fluid flow. These devices help keep equipment running efficiently and prevent costly downtime. Y-Type Strainers Y-type industrial strainers are utilized in liquid applications across a range of industries to protect downstream equipment from unwanted debris, such as sand, gravel, and other particles that could clog pipes or mechanical devices. These strainers ensure the cleanest possible liquid environment for downstream equipment during processing operations. They can also be employed in steam and natural gas applications to prevent rust, sediment, and other debris from damaging pipelines and equipment. They work efficiently across a range of pipe sizes and often feature blow-off connections for easier cleaning. Basket Type Strainers Basket strainers are a type of filtration system used to remove solid particles from liquid and gas streams. They come in various shapes and sizes, as well as being made from various materials like metal or plastic. Furthermore, these strainers can be tailored to fit various applications. Depending on the application, strainers can be designed with either a perforated or solid mesh basket that allows liquid or gas through while trapping contaminants. They may also feature an internal strainer body that houses the basket for convenience. Temporary Strainers Temporary industrial strainers serve the primary purpose of filtering out debris and solids during the construction, installation, or flushing of a line. This filtration prevents contamination, helps maintain process integrity, and shields equipment from particulates that could damage it. Temporary strainers are frequently employed in upstream applications like drilling oil, derrick/mast construction, draw works, and top drive, as well as within mud/fuel tanks, power/pump stations, and shaker units. Furthermore, they have downstream applications like hydrocracking and filtration. Twin Strainers or Duplex Strainers Twin strainers sometimes referred to as duplex or double basket strainers, that are designed for removing large particles of dirt and debris from fuel, oil, or water lines. These systems typically consist of two separate basket housings with a valve handle in between that diverts liquid flow to one basket while the other is being cleaned or serviced. You can choose duplex strainers with self-cleaning elements or backwashing systems that scrape along the inside of the mesh to remove debris and recirculate clean fluid. Both models offer high-efficiency levels for continuous flow applications such as chemical processing plants, power plants, cooling towers/lines, compressors/condensers/oil burners/pump stations/water treatment facilities – just to name a few! Some Special Strainer Types T-Type Strainers: T-type strainers are distinguished by a vertically oriented chamber, usually larger than that of Y-type strainers. Their dirt-holding capacity is greater than that of Y-type strainers, making them an ideal choice for liquid applications. Self-cleaning Strainers: These strainers allow dirt accumulation to be cleaned without shutting down the plant. They feature a scraper or brush that rakes over the screen surface, dislodging any particles stuck in it. Colander Strainers: Colander-type strainers are ideal for draining pasta, vegetables, and other items. They come in various sizes to meet your filtration requirements; either perforated metal or wire cloth construction makes it easy to find one that meets your criteria. Magnetic Strainers: Magnetic strainers have magnets that attract iron molecules to themselves, helping prevent pump seals from rusting. They’re commonly installed before pumps and other piping apparatus. Temporary Strainers: Temporary strainers are designed for short-term services, such as during the start-up of new fluid systems or after significant retrofits. They attach between two flanges on a pipeline and are removed after an established amount of time has elapsed. How Do Strainers Function in a Pipeline? A strainer’s purpose is to screen through the flow medium, separating larger debris from smaller ones. This helps protect equipment downstream of the pipeline. Additionally, this filter media removes fine particles from the fluid to help prevent clogging, thus eliminating the need for frequent pipe cleaning appointments. When selecting a mesh size for your strainer, remember that it will determine how much liquid can pass through it. Ideally, select a mesh with perforations around one-fourth the diameter of the smallest particles your pipeline needs to filter out. Pipeline strainers can be tailored to meet the exact specifications of a project. They come with various connections and ports, exotic alloys, and special coatings, as well as design specifications regarding differential pressure, flow velocity, and particle holding capacity.

    What You Need To Know About Globe Valves-2

    How Globe Valves Work? A globe valve is a multi-directional device that can open, close or throttle fluid flow. It consists of five major parts: the valve body, bonnet, handwheel, stem, and plug. Valve Stem: The stem of a globe valve connects with the handwheel and operates the opening or closing action of the valve. It may be either smooth sliding or threaded. Bonnet: The bonnet of a globe valve attaches to the stem and protects it from damage. Its seal, made from wear-resistant material, provides leak-proof closure for any media inside of the valve. Ball Disc: The valve disc is another important element of a globe valve, used for low-temperature and low-pressure applications. Seat Ring: The seat ring of a globe valve is where the disc fits and stops the fluid flow. Generally, this part can be screwed or threaded into an existing thread cut in the valve body to prevent removal during repairs or servicing. Disc and Seat Capabilities: Globe valve discs come in various patterns, each providing its own advantages. Globe valves are typically mounted, so the pressure is above the disk in high-temperature steam service and below it in lower-temperature or lower-pressure applications. This makes for easier operation and protects packing while reducing erosive action on seat and disk faces.   Generally, globe valves are designed for straight-through flow with ports oriented at right angles to the pipe axis. However, they come in various configurations, most often two-port but also three-port varieties. Types of Globe Valves Globe valves are widely used in industrial and marine applications to start, stop, and regulate flow, as well as isolate and throttle functions.  Angle Globe Valve Angle globe valves, also known as Y-pattern globe valves, are designed with an angled body that allows for a change in flow direction.  This design is particularly useful in applications where space is limited or when a more convenient flow path is required.  Angle globe valves find applications in various industries, including petrochemical, chemical, and oil and gas, where they are commonly used for throttling and control. T-pattern Globe Valve T-pattern globe valves, or straight-pattern globe valves, feature a straight-through flow path, making them suitable for applications where minimal pressure drop is crucial.  These valves are often preferred in systems with high-velocity flows, such as steam applications.  T-pattern globe valves are commonly utilized in power plants, steam distribution systems, and other industrial settings. Bellows-sealed Globe Valve Bellows-sealed globe valves incorporate a bellows element that provides an additional barrier between the process fluid and the environment.  This design enhances the valve’s ability to prevent leakage, making it ideal for applications involving hazardous or toxic fluids.  Bellows-sealed globe valves are frequently employed in chemical processing, pharmaceuticals, and other industries where leak-tight performance is critical. Cryogenic Globe Valve Cryogenic globe valves are specially designed to operate in extremely low-temperature environments, such as those found in liquefied natural gas (LNG) facilities and cryogenic storage systems.  These valves are equipped with materials and features that ensure reliable performance under cryogenic conditions, providing effective control over the flow of cryogenic fluids. Stop-check Globe Valve Stop-check globe valves combine the functionalities of both a globe valve and a check valve.  They allow for throttling or complete shutoff of fluid flow while also preventing backflow.  These valves are commonly used in applications where the prevention of reverse flow is essential, such as in boiler feedwater systems and high-pressure steam lines. Pressure-seal Globe Valve Pressure-seal globe valves are designed to handle high-pressure applications, featuring a unique construction that enhances their ability to withstand elevated pressures.  These valves are commonly used in power generation, oil and gas pipelines, and other systems where high pressures are encountered.  The pressure-seal design ensures reliable performance and tight sealing under demanding conditions. What’s the Application of Globe Valve A globe valve is a type of valve that restricts or stops the fluid flow. They’re commonly found in piping systems transporting corrosives, viscous, or highly pressurized media. They come in a range of patterns, each offering its own advantages. Furthermore, their ease of upkeep and ability to be repaired or replaced makes them an economical choice for many applications. As its name implies, globe valves feature a spherical body. Two halves of this globe valve are separated by an internal baffle which contains an opening that acts as a seat for attaching a movable plug to close (or shut) the valve. Globe valves are widely used industrial valves that can start, stop, and throttle fluid flow. They’re often found in systems requiring frequent throttling or regulating, such as vacuum systems, water hammer control, and systems operating at various temperatures. Pros and Cons of Globe Valves Pros of Globe Valves Precise Flow Control: Globe valves excel at providing precise control over the flow of fluids.  Their design allows for accurate throttling, making them suitable for applications that require fine adjustments to the flow rate. Versatility: Globe valves are versatile and find application in a wide range of industries, including petrochemical, chemical processing, power generation, and water treatment.  They are well-suited for various fluid types, temperatures, and pressures. Good Shut-Off Capability: Globe valves offer excellent shut-off capability, ensuring a tight seal when closed.  This makes them effective in preventing backflow and leakage, contributing to their reliability in critical systems. Sturdy Construction: These valves are often built with robust materials, enhancing their durability and longevity.  The materials used in their construction can be selected based on the specific requirements of the application. Ideal for Throttling: The globe valve’s design, with a disc or plug that can be moved against the flow, makes it well-suited for throttling applications.  This feature allows for precise control over the flow rate. Cons of Globe Valves Pressure Drop: Globe valves can cause a significant pressure drop across the valve, particularly in fully open positions.  This can impact system efficiency, and in high-pressure systems, it may require additional energy to overcome the pressure drop. Size and Weight: Globe valves can be relatively large and heavy compared to other types of valves.  In applications where space and weight are critical considerations, the size and weight of globe valves may pose challenges. Slower Operation: Compared to some other valve types, such as ball valves, globe valves generally have slower opening and closing times.  This slower operation may be a limitation in systems requiring rapid response times. Complex Design: The internal design of globe valves can be more complex than that of some other valves.  This complexity may result in higher manufacturing costs and increased maintenance requirements. Limited Use in High-Flow Applications: Globe valves are not always the best choice for high-flow applications, especially where minimal resistance and pressure drop are crucial.  In such cases, other valve types like butterfly or ball valves might be more suitable. How to Choose Between Globe Valve vs. Ball Valve When selecting plumbing components, there are two primary valve types to consider: globe and ball. Both offer reliable on/off controls with distinct advantages that may be worth taking into account for your project. When selecting a valve to control, start, or stop flow in a fluid system, it is essential to learn which type is most suitable for your application. The two most common types of fluid control valves are globe and ball valves. Ball valves and globe valves differ in that they use a disk to open, while globe valves utilize a ball with an integral hole. When one opens the valve, fluid can pass through while the ball rotates to block its passage when closed.   The primary distinction between a ball valve and a globe valve lies in their closure elements. A ball valve features a spherical closure element that seals against an internal seat; on the other hand, globe valves feature disk-shaped closure elements that fit onto an outer seat.

    What You Need To Know About Globe Valves

    What You Need To Know About Globe Valves In this article, we cover everything you need to know about globe valves, including their types, parts, and working principles.  Plus, we provide tips on how to select the ideal globe valve based on factors such as material, size, and pressure limits.   Globe valves are regulating or shutoff valves used to control liquid flow.  They come in various styles and configurations to meet specific needs and applications.  Selecting the ideal globe valve for your application can be daunting due to its various shapes and design variants.  Globe valves come in a range of materials, sizes, and pressure limits to meet your application.  Selecting the appropriate one is key to getting maximum performance from your valve.   Let’s take a detailed look into the globe valves and how to choose the best one for you. What Are Globe Valves? A globe valve is a linear motion closing-down valve that utilizes a disc to start, stop, and throttle fluid flow.  The seat opening varies in direct proportion to disc travel and thus makes it ideal for tasks requiring controlling flow rate.   Globe Valves can be employed in a number of applications, such as steam and condensate service, temperature or pressure regulation in pipelines, and even nuclear plant process control.  They come with various body and stem designs that can be tailored to meet specific requirements.   Globe valve disk designs come in three basic forms: ball, composition, and plug.  The ball disk is ideal for low-pressure or temperature applications, while the composition disk features a hard insert ring that ensures tight closure.  Finally, plug disks offer better throttling than either ball or composition disks and may be used when hard service requirements exist. Globe valves come in several body patterns, the three most popular being standard, angle, and Y-shaped.  Of these three options, the standard pattern is by far the most prevalent and typically employed for throttling services. What Are the Parts of a Globe Valve? A typical globe valve consists of the following parts:   Back Seat The back seat in a globe valve is positioned at the rear of the valve body.    Its primary function is to provide a secondary seating surface, preventing system leakage when the valve is fully open.    It serves as a safety feature, especially during maintenance or repairs, offering a redundant seal. Bonnet The bonnet is a crucial part of the globe valve, securing the internal components and acting as a cover for the valve body.    It is attached to the valve body and houses the stem and disc assembly. The bonnet plays a key role in maintaining the integrity of the valve’s internal structure.   Disc or Plug The disc or plug is the movable component within the globe valve that regulates the flow of fluid.    When the valve is in operation, the disc moves against the seat to either allow or block the flow.    The disc design varies based on the valve’s intended application and flow control requirements. Gland Bolts and Nuts Gland bolts and nuts are used to secure the gland, which houses the packing material.    These bolts and nuts ensure proper compression of the packing, preventing leaks along the stem.   Gland Bushing and Flange The gland bushing provides support to the stem and ensures a tight seal around the stem. The gland flange secures the gland assembly and provides structural stability to the valve. Handwheel (Mechanical Actuator) The handwheel serves as a manual actuator, allowing users to control the opening and closing of the valve. It is an essential component for operations requiring human intervention.   Packing Packing is a sealing material placed around the stem to prevent fluid leakage along the stem. It provides a secure seal while allowing the stem to move freely during operation.   Pressure Seal Gasket The pressure seal gasket ensures a tight seal between the valve body and the bonnet, preventing fluid leakage under high-pressure conditions.   Seat Ring The seat ring is a stationary part of the valve where the disc or plug makes contact to create a seal. It is essential for controlling the flow and preventing leakage. Stem The stem connects the handwheel or actuator to the disc or plug, transmitting the force required to control the flow. It is a critical component for the overall functionality of the valve.   Valve Body (Globular Shape) The valve body, typically with a globular shape, houses the internal components and provides the main structure for the valve. It features inlet and outlet ports for fluid flow.   Yoke The yoke is a bracket-like structure that supports the stem and helps in the proper alignment of the moving parts. It ensures smooth operation and stability.   Yoke Sleeve The yoke sleeve surrounds the stem and protects it from external elements. It contributes to the overall durability and longevity of the valve.

    The Complete Guide To Triple Eccentric Butterfly Valves

    Introduction Triple eccentric butterfly valves are essential components in fluid control systems, known for their high performance and reliable operation. These valves offer excellent sealing capabilities and are widely used in various industries. In this news, we will provide a complete guide to triple eccentric butterfly valves, including their definitions, types, working principles, and key features. This information will help you understand the functionality and applications of these valves in different industries. Definition and Types of Triple Eccentric Butterfly Valves Triple eccentric butterfly valves are innovative valve designs that incorporate three offsets to achieve superior sealing performance. These valves feature a unique design with a conical metal seat and a sealing disc that moves off the seat with a triple eccentricity. They can be classified into the following types: Metal-seated Triple Eccentric Butterfly Valves:  These valves are equipped with a metal seat and a metal sealing disc, providing excellent sealing performance and resistance to high temperatures and corrosive fluids. Soft-seated Triple Eccentric Butterfly Valves:  Soft-seated triple eccentric butterfly valves use resilient materials such as rubber or PTFE for the seat and sealing disc, offering reliable sealing and bubble-tight shut-off. Working Principles of Triple Eccentric Butterfly Valves Triple eccentric butterfly valves operate based on the principle of the triple offset design. The disc, with its triple eccentricity, allows the sealing edge to move away from the seat in a non-rubbing, cam-like motion. This off-center rotation of the disc ensures a tight and bubble-tight seal against the seat, even under high-pressure conditions. When the valve is fully open, the disc is completely clear of the flow path, minimizing pressure drop and providing unobstructed flow. Key Features and Advantages of Triple Eccentric Butterfly Valves Triple eccentric butterfly valves offer several features that make them advantageous in fluid control applications. Some key features include: Excellent Sealing Performance:  The triple eccentric design provides a tight and bubble-tight seal against the seat, ensuring reliable shut-off and minimizing leakage. High-Performance Operation:  These valves offer low torque and easy operation, making them suitable for automation and remote control applications. Wide Temperature and Pressure Range:  Triple eccentric butterfly valves can handle a wide range of temperatures and pressures, making them versatile for various industries and applications. Bi-Directional Flow Capability:  These valves can accommodate bi-directional flow, providing flexibility in fluid control systems. Triple Eccentric Butterfly Valves vs Triple Offset Butterfly Valves Triple Eccentric Butterfly Valves have three eccentricities between the disc and the valve body, namely axial eccentricity, radial eccentricity, and rotational eccentricity. This structure prevents the disc from direct contact with the valve body during rotation, thereby reducing friction and wear, and improving sealing performance and service life. Triple offset butterfly valves have only two eccentricities between the disc and the valve body, namely axial eccentricity and radial eccentricity. The sealing performance and service life of this structure are better than those of ordinary butterfly valves, but worse than those of Triple Eccentric Butterfly Valves. Sealing performance: Triple Eccentric Butterfly Valves have better sealing performance because the disc does not have direct contact with the valve body during rotation, thus reducing friction and wear. Service life: Triple Eccentric Butterfly Valves have a longer service life because of their better sealing performance, less friction and wear. Operating torque: Triple Eccentric Butterfly Valves have a smaller operating torque because the disc does not have direct contact with the valve body during rotation, thus reducing resistance. Flow resistance: Triple Eccentric Butterfly Valves have a smaller flow resistance because the disc does not have direct contact with the valve body during rotation, thus reducing friction between the seat and the disc. Applications of Triple Eccentric Butterfly Valves Triple eccentric butterfly valves find applications in industries where reliable sealing, high-performance operation, and versatility are required. Some common applications include power plants, oil and gas, petrochemicals, water treatment, and process industries. They are used for regulating flow, isolating pipelines, and providing efficient control in demanding environments. Conclusion Triple eccentric butterfly valves are advanced valve solutions known for their exceptional sealing performance and high-performance operation. With their excellent sealing capabilities, wide temperature and pressure range, and bi-directional flow capability, triple eccentric butterfly valves offer reliable and efficient fluid control solutions.
