Applications of Strainers in Industry Strainers are used industrially for filtering liquids like water, oil, and sand. Additionally, they remove rust, leaves, and other organic debris from the flow stream. When processing materials, different mesh sizes are employed to capture particles of 40 microns or greater. 60-mesh strainers typically capture particles at 240 microns, while 100-mesh strainers can handle particles as small as 150 microns or greater. When selecting a strainer, material sensitivity to flow is an important consideration. This can be determined by pipeline velocity, differential pressure drop, and open area ratio. Pipeline Velocity – This refers to the speed of liquid through a system, measured in gallons per minute (GPM). Accurate measurement of this flow rate is essential in selecting an appropriate strainer size and determining what differential pressure can be experienced without damaging the basket. Viscosity (Viscosity) – Viscosity is the sensitivity of a fluid to flow, and it’s essential to understand how viscosity varies based on temperature and the material being filtered. Dirt Loading (DL) – This refers to the weight percentage of particulate contaminants in a pumped liquid or slurry form that must be removed for moisture removal. It’s essential that this liquid be correctly pumped in order to avoid filter clogging and subsequent system malfunction. How To Select A Pipeline Strainer? A pipeline strainer is an advanced filter that separates contaminants and particulates from the liquid. Not only does this improve efficiency in a process, but it can reduce maintenance costs, too, since particles won’t damage downstream equipment. When selecting a strainer for your pipeline, there are several factors to take into account. One of these is the size of the hole and mesh, which determines how many particles can be captured by the strainer. In general, strainers should have holes slightly smaller than the particles you want to filter. This ensures any foreign debris is captured before reaching downstream equipment and helps protect your investment. When selecting a basket filtering element, there are a few essential things to take into account. Strainers' materials used can significantly affect how well the element will hold up under high pressure. When selecting a pipeline basket strainer, the open area ratio (OAR) should be taken into account. This quantity determines how long a strainer can be used without cleaning or losing pressure across its basket or screen. In most cases, the OAR is calculated by analyzing the relationship between an internal cross-section area of a basket or screen and its overall open area. A wider opening allows more time for the basket or screen to work without needing cleaning, which may cause pressure loss. Differentiating Filters and Strainers When it comes to particulates that need removal, the size of the particles can determine which strainer or filter is appropriate. If they are larger than 40 microns in diameter, a strainer would be an optimal option; if smaller, then filtering would be the better solution. Selecting the correct mesh for a strainer or filter is critical in determining its effectiveness and how often it must be cleaned. If particulates being removed are extremely fine, a finer mesh may be needed; however, this would also necessitate more frequent cleaning sessions. Another critical distinction between a strainer and a filter is the pressure of gas or liquid that passes through them. With a strainer, there is no noticeable drop in pressure as the substance passes through. Conversely, substances passing through a filter will typically experience an abrupt decrease in pressure regardless of whether they need to be cleaned or not. This is essential because lower pressure enhances filtration efficiency and minimizes the possibility that debris will escape from the system.

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.

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.
