Y Type Strainer 150LBS Applications
• Water treatment and distribution: municipal water networks, pump suction protection, irrigation systems.
• HVAC and district heating: chilled water, hot water, and steam distribution in commercial buildings.
• General industrial service: low-pressure oil, gas, and steam pipelines requiring reliable filtration.
• Chemical processing: reagent feed lines and corrosive media filtration with CF8 / CF8M body.
• Marine and offshore: seawater and offshore service with duplex stainless body (4A / 5A).
• Fire protection: fire main lines and sprinkler systems where debris protection is critical.
FAQ - Y Type Strainer 150LBS
Q1: What is the pressure rating of Class 150 Y type strainer?
A: Class 150 Y type strainer has a design pressure of 19.6 bar (285 psi) at ambient temperature, in accordance with ASME B16.34. It is the most economical pressure class in the Y strainer series, suitable for general water, HVAC, and low-pressure industrial service. For higher pressure, Class 300, 600, 900, and 1500 are also available.
Q2: What is the maximum size available for Class 150 Y type strainers?
A: Class 150 Y type strainers are available from 1/2 inch to 36 inch (DN15 to DN900). This is the widest size range among all pressure classes because Class 150 is used for large-diameter low-pressure pipelines. Cast type is used for sizes up to 24 inch, and welded/fabricated type is available for larger sizes up to 36 inch and beyond.
Q3: What is the difference between RF and BW ends for Class 150 Y strainers?
A: RF (Raised Face) flanged ends allow easy installation and removal for maintenance — preferred for pipeline service where strainers are periodically cleaned. BW (Butt Weld) ends provide a permanent leak-tight welded connection — preferred for high-integrity service where no leakage is acceptable. For Class 150, both are commonly used; RF is more common for general water and HVAC service, and BW for chemical and steam service.
Q4: What body materials are recommended for Class 150 Y strainers?
A: For general water, steam, and non-corrosive service, WCB carbon steel is the most economical choice. For low-temperature service down to -46°C, LCB or LCC is recommended. For corrosive media, CF8 (SS304) or CF8M (SS316) is preferred. For seawater, desalination, and offshore service, duplex stainless steel (A890-4A or 5A) offers the best chloride resistance. Cast iron and ductile iron are also available for municipal water service.
Q5: How do I select the right mesh size for Class 150 water service?
A: For water service, industry practice is to use 18–30 mesh. Standard Y strainers are supplied with 20–40 mesh SS screens. 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, 100–200 mesh can be specified. Please specify mesh size when requesting a quotation.
Q6: How do I maintain a Class 150 Y strainer?
A: Class 150 Y strainer maintenance is simple: isolate the strainer, depressurize, remove the cover bolts (bolted cover design), take out the screen, clean or replace it, and reassemble. The Y-shaped body allows screen removal without disconnecting the pipeline. For continuous operation, a bypass line or dual-strainer configuration is recommended. Screen replacement is recommended when the pressure drop exceeds the initial clean-screen value by 0.5–1.0 bar.
