Y Type Strainer 600LBS Applications
• Oil refinery and petrochemical: high-pressure process lines, hydrotreating, catalytic cracking, and reagent feed systems.
• Power generation: high-pressure steam mains, feedwater, condensate, and turbine protection lines.
• High-pressure gas transmission: natural gas and process gas pipelines requiring RTJ or BW leak-tight connections.
• Chemical processing: high-pressure reagent and corrosive media filtration with CF8M or duplex body.
• Offshore and marine: seawater injection and offshore high-pressure service with duplex 4A / 5A body and 2205 / 2507 screen.
• High-pressure water systems: boiler feedwater, descaling, and hydraulic systems where debris protection is critical.
FAQ - Y Type Strainer 600LBS
Q1: What is the pressure rating of Class 600 Y type strainer?
A: Class 600 Y type strainer has a design pressure of 102 bar (1,480 psi) at ambient temperature, in accordance with ASME B16.34. It is the standard choice for high-pressure process, refinery, and power plant service. For higher pressure, Class 900 and 1500 are also available; for lower pressure, Class 150 and 300 are more economical.
Q2: What is the difference between RF, RTJ and BW ends for Class 600 Y strainers?
A: RF (Raised Face) flanged ends are the most common for general high-pressure 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 preferred in refinery and gas transmission. BW (Butt Weld) ends provide a permanent welded connection with no potential leak path, preferred for high-integrity and buried pipelines.
Q3: What screen materials are available for Class 600 Y strainers?
A: Standard screen materials are SS304 and SS316. For high-chloride or corrosive high-pressure service, duplex stainless steel 2205 and 2507 screens are available. 2205 offers excellent chloride stress corrosion resistance; 2507 (super duplex) offers higher strength and corrosion resistance for the most demanding offshore and seawater injection service.
Q4: What body materials are recommended for Class 600 Y strainers?
A: For general high-pressure steam, oil, 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 under high pressure.
Q5: How do I select the right mesh size for Class 600 high-pressure service?
A: For high-pressure steam and gas service, 40–100 mesh is commonly specified to protect turbines and downstream equipment. For high-pressure water and hydraulic systems, 60–200 mesh is typical. For refinery oil and chemical service, 100–200 mesh provides fine filtration. Note that finer mesh increases pressure drop; verify allowable pressure drop across the strainer before final selection.
Q6: How do I maintain a Class 600 high-pressure Y strainer?
A: Class 600 Y strainer maintenance is similar to lower pressure classes but with higher bolt torque requirements: isolate the strainer, depressurize completely, remove the cover bolts (bolted cover design), take out the screen, clean or replace it, install a new gasket (graphite or RTJ ring), and retorque bolts to specification. The Y-shaped body allows screen removal without disconnecting the pipeline. For continuous high-pressure operation, a bypass line or dual-strainer configuration is strongly recommended.
