FAQ - Industrial Y Type Strainer
Q1: What is the difference between cast, fabricated and welded body structures?
A: Cast type is sand-cast and precision machined, suitable for sizes 1/2 to 24 inch and standard industrial service, offering the best balance of cost and quality for medium sizes. Fabricated type is welded from plate and pipe, suitable for large sizes 2 to 36 inch with custom dimensions and short lead time. Welded type combines a forged or cast body with a welded cover, providing permanent leak-tight seal for high-pressure service up to 6 inch, ideal for critical installations where no leakage is acceptable.
Q2: Which shell material should I choose for corrosive media?
A: For general water and non-corrosive service, WCB carbon steel is the most economical choice. For corrosive media, choose CF8M / SS316 with Mo content for chloride resistance. For severe chloride and seawater service, duplex stainless steel (SAF2205 or SAF2507) is recommended. For low-temperature service down to -46°C, LCB / LCC low-temperature carbon steel should be selected. Cast iron and ductile iron are available for municipal water and HVAC service.
Q3: How do I select the right mesh size for my industrial Y strainer?
A: Mesh selection depends on the medium and the particle size to be removed. Industry practice: water service uses 18–30 mesh, gas service uses 40–100 mesh, and oil service uses 100–480 mesh. For pump protection, select a mesh that captures particles at least 1/3 the size of the smallest critical clearance in downstream equipment. For finer filtration in instrument lines, 200–400 mesh can be specified. Contact us for mesh selection guidance based on your specific application.
Q4: What end connections are available for industrial Y type strainers?
A: We offer Flanged (FF, RF, RTJ) per ANSI B16.5 and DIN standards, Butt Weld (BW) per ANSI B16.25, Socket Weld (SW) per ANSI B16.11, and Threaded (NPT) ends. The choice depends on piping specification, pressure class and installation requirements. RF flanged ends are most common for general industrial service; BW ends are preferred for high-integrity welded piping systems.
Q5: What is the difference between bolted bonnet and bolted cover?
A: Bolted Bonnet (B.B.) uses a flanged bonnet bolted to the body with a gasket, allowing easy access for screen cleaning and replacement. Bolted Cover (B.C.) is a similar design with a flat cover plate. Both designs allow online blowdown cleaning via drain plug and full screen access for maintenance. Bolted bonnet is more common for larger sizes; bolted cover is preferred for compact installations.
Q6: What pressure standards are covered by your industrial Y type strainers?
A: We cover both ANSI and DIN pressure standards: ANSI Class 150Lb, 300Lb, 600Lb, 900Lb and 1500Lb; DIN PN10, PN16, PN25, PN40 and PN64. The choice depends on project piping specification. Class 150 to 300 is common for general industrial and municipal service; Class 600 to 1500 is used for high-pressure process, power plant and offshore applications. Contact us with your requirements for a specific pressure class.
