• Power plant high-pressure service: high-pressure steam mains, boiler feedwater and turbine protection lines with heavy-wall Class 600 tee strainer.
• High-pressure gas transmission: natural gas and process gas pipelines requiring RTJ ring joint sealing and Class 600 high-pressure rating.
• High-pressure chemical process: corrosive media filtration with SS304 / SS316 / SS304L / SS316L body and 304SS / 316SS screen.
• Offshore and high-pressure service: offshore platform process piping requiring RTJ end connection for leak-tight sealing.
• High-pressure water systems: boiler feedwater, descaling and hydraulic systems requiring Class 600 high-pressure filtration.
FAQ - Tee Type Strainer 600LBS
Q1: What is a Tee Type Strainer 600LBS?
A: A Tee Type Strainer 600LBS (also called Tee Strainer) is a fabricated pipeline strainer with a T-shaped body, rated to ANSI Class 600 (102 bar / 1,480 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 Class 600 tee type strainer has a heavy wall thickness of 6.4mm and is available in Straight Type and Angle Type, making it the standard choice for high-pressure refinery, power plant and high-pressure process piping service.
Q2: What is the size range and end connection available?
A: Tee type strainer 600LBS is available from 2 inch to 24 inch (DN50 to DN600). End connections include Flanged RF (Raised Face), RTJ (Ring Joint) and Butt Weld (BW) to ASME B16.5 (under 24 inch) or ASME B16.47 A (above 24 inch). Face-to-face dimension follows ASME B16.10. For Class 600 high-pressure service, RTJ end connection is commonly specified for high-pressure and high-temperature service with metal ring gasket for leak-tight sealing. Cover type is bolted cover (blind flange) with drain plug for maintenance.
Q3: What body materials are available for tee type strainer 600LBS?
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; for RTJ end, RTJ ring joint gasket is used. Screen is 304SS / 316SS / DSS. Carbon steel WPB is the standard and most economical choice for Class 600 process piping service; SS316 and DSS are selected for corrosive and offshore service.
Q4: What is the difference between RF, RTJ and BW ends for tee type strainer 600LBS?
A: RF (Raised Face) flanged ends are the most common for general Class 600 service and allow easy maintenance. RTJ (Ring Joint) ends use a metal ring gasket for leak-tight sealing in high-pressure and high-temperature service, and are strongly preferred in refinery and high-pressure gas transmission at Class 600 and above. BW (Butt Weld) ends provide a permanent welded connection with no potential leak path, preferred for high-integrity and buried pipelines. The three end types have different face-to-face length (L) dimensions, as shown in the dimension table above. For Class 600 tee type strainer, RTJ is the industry standard for critical high-pressure service.
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 high-pressure process piping and pump protection, 40 to 100 mesh is common; for fine chemical and instrument protection, 100 to 200 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 600LBS?
A: Maintenance requires strict procedure: isolate the strainer, depressurize completely, and confirm zero pressure. 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 retorque bolts to specified torque value in a star pattern. For RTJ end connection, install a new RTJ ring joint gasket during reassembly. For large diameter tee type strainer (above 16 inch), a davit arm design is recommended for heavy cover lifting without crane. After maintenance, pressure test is required before returning to service. Screen replacement is recommended when the pressure drop exceeds the initial clean-screen value by 0.5-1.0 bar.
