FAQ - Tee Type Strainer 150LBS
Q1: What is a Tee Type Strainer 150LBS?
A: A Tee Type Strainer 150LBS (also called Tee Strainer) is a fabricated pipeline strainer with a T-shaped body, rated to ANSI Class 150 (19.6 bar / 285 psi at ambient temperature). It removes foreign particles and impurities from liquid and gases using a perforated screen or wire mesh basket, protecting downstream pumps, valves, meters and other equipment. The tee type strainer is available in Straight Type and Angle Type, and is the standard choice for large diameter low-pressure pipeline service up to 48 inch (DN1200).
Q2: What is the size range and end connection available?
A: Tee type strainer 150LBS is available from 2 inch to 48 inch (DN50 to DN1200). End connections include Flanged RF (Raised Face) to ASME B16.5 (under 24 inch) or ASME B16.47 A (26 inch and above), and Butt Weld (BW) to ASME B16.25. Face-to-face dimension follows ASME B16.10. Cover type is bolted cover (blind flange) with drain plug for maintenance. The tee type strainer is particularly suitable for large diameter service, with the tee body fabricated from wrought steel materials.
Q3: What body materials are available for tee type strainer?
A: Body materials include carbon steel A234-WPB, stainless steel 304SS / 304LSS / 316SS / 316LSS and duplex stainless steel DSS. Flange and cover are in A105 for carbon steel or A182-F304 / F304L / F316 / F316L for stainless steel. Gasket is graphite + 304SS / 316SS / 304LSS / 316LSS; screen is 304SS / 316SS / DSS. For high-chloride or seawater service, duplex and super duplex materials are available on request. Carbon steel WPB is the standard and most economical choice for Class 150 water and general industrial service.
Q4: What is the difference between RF and BW ends for tee type strainer?
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, buried pipeline or where no leakage is acceptable. For Class 150 tee type strainer, both are commonly used; RF is more common for general industrial service, and BW for high-integrity and buried pipelines. The RF and BW ends have different face-to-face length (L) dimensions, as shown in the dimension table above.
Q5: What screen and mesh sizes are available?
A: Screens are supplied in stainless steel 304SS, 316SS and duplex stainless steel DSS. Mesh sizes include 20, 40, 60, 80, 100, 200 and 400 mesh, tailor-made to customer requirements. For large diameter water and HVAC service, 20 to 40 mesh is common; for process piping and pump protection, 60 to 100 mesh is specified. The perforated plate and wire mesh can be combined for high dirt load service. Please specify the mesh size when requesting a quotation.
Q6: How do I maintain a tee type strainer 150LBS?
A: Maintenance is simple: isolate the strainer, depressurize, open the drain plug to drain the strainer, remove the blind flange cover bolts, take out the screen, clean or replace it, install a new gasket, and reassemble. The tee type strainer body has a bolted cover (blind flange) on the branch chamber for easy access. Because the branch chamber is isolated from the main flow path, opening it does not cause a massive spill of process fluid. For large diameter tee type strainer (above 24 inch), a davit arm design is recommended for heavy cover lifting without crane. Screen replacement is recommended when the pressure drop exceeds the initial clean-screen value by 0.5-1.0 bar.
