Why Choose an API Cast Steel Y Type Strainer?

API cast steel Y type strainers are widely used in oil, gas, petrochemical and power generation pipelines to protect pumps, valves, meters and other equipment from debris. The Y-shaped body allows the screen to be positioned in the flow path, capturing particles while maintaining a compact installation footprint. This strainer is designed to ASME B16.34 and tested to API 598, with body materials covering carbon steel, low temperature steel, stainless steel and duplex options. NACE MR0175 compliance is available for sour service, making it suitable for oil and gas production with H2S content. Flanged RF, RTJ and BW ends cover most pipeline connection requirements.

Applications

• Oil & gas transmission pipelines
• Petrochemical and refinery process lines
• Power plant steam and water systems
• Chemical and industrial process pipelines
• Sour service pipelines (NACE MR0175)
• Protection of pumps, valves and meters
