Y Type Strainer 1500LBS Applications
• Ultra high-pressure wellhead: onshore and offshore wellhead flow lines, choke and kill manifolds, and gas injection systems.
• Subsea production: subsea trees, manifolds, and subsea injection lines requiring RJ ring joint sealing and duplex body.
• Ultra high-pressure gas injection: gas lift and gas injection systems for enhanced oil recovery.
• Hydroprocessing and refining: ultra high-pressure hydrogen service, hydrocracker and hydrotreater protection lines.
• Sour gas and ultra high-pressure chemical: H2S-containing gas and corrosive ultra high-pressure media filtration with CF8M or A995 duplex body.
• Very high-pressure steam: supercritical boiler and ultra high-pressure turbine protection lines in power plants.
FAQ - Y Type Strainer 1500LBS
Q1: What is the pressure rating of Class 1500 Y type strainer?
A: Class 1500 Y type strainer has a design pressure of 260 bar (3,750 psi) at ambient temperature, in accordance with ASME B16.34. It is the standard choice for ultra high-pressure wellhead, subsea, and gas injection service. For lower pressure, Class 900 is more economical for onshore high-pressure process; for higher pressure, Class 2500 is available for the most extreme subsea service.
Q2: Why is RJ end connection recommended for Class 1500 Y strainers?
A: At Class 1500 ultra high-pressure rating, connection sealing reliability is critical for safety. RJ (Ring Joint) ends use a metal ring gasket compressed into a groove between the flange faces, providing a leak-tight metal-to-metal seal under extreme pressure and temperature. RJ is the industry standard for wellhead and subsea service. RF flanged ends can be used for general ultra high-pressure service with lower safety requirement, and BW ends are preferred for permanent or buried pipelines where no leak path is acceptable.
Q3: What screen material is suitable for Class 1500 DSS service?
A: For Class 1500 ultra high-pressure service, DSS (duplex stainless steel) screens are recommended. DSS 2205 is suitable for most subsea and wellhead service with excellent chloride stress corrosion resistance. DSS 2507 (super duplex) offers higher strength and corrosion resistance for sour gas (H2S-containing) and the most demanding subsea injection service. SS304 and SS316 screens are available for non-corrosive ultra high-pressure service, but are not recommended for chloride-containing media.
Q4: What body materials are recommended for Class 1500 Y strainers?
A: For general ultra high-pressure steam, oil, and gas service, WCB carbon steel is the most economical choice. For low-temperature service down to -46°C, LCB or LCC is recommended. For sour gas and corrosive ultra high-pressure media, CF8M (SS316) is preferred. For subsea wellhead, seawater injection, and offshore service, A995 duplex stainless steel (4A or 5A, including super duplex) offers the best chloride and sour resistance under ultra high pressure.
Q5: What is the maximum size available for Class 1500 Y type strainers?
A: Class 1500 Y type strainers are available from 2 inch to 24 inch (DN50 to DN600). The maximum size is limited because at ultra high pressure the wall thickness and weight increase rapidly with diameter, making large sizes uneconomical. For sizes above 24 inch, a special fabricated design may be evaluated; please contact us with your specific wellhead or subsea requirement.
Q6: How do I maintain a Class 1500 ultra high-pressure Y strainer?
A: Class 1500 Y strainer maintenance requires very strict procedure: isolate the strainer, depressurize completely, and confirm zero pressure. Remove the cover bolts (bolted cover design) following the correct loosening sequence in reverse. Take out the screen, clean or replace it. Install a new gasket (graphite or RJ ring joint) and retorque bolts to the specified torque value in a star pattern in multiple passes. The Y-shaped body allows screen removal without disconnecting the pipeline. For continuous ultra high-pressure operation, a bypass line or dual-strainer configuration is strongly recommended, and pressure test is required before returning to service.
