TECHNICAL DATA SHEET
Product: 1-1/2″ – Class 800 Y‑Pattern Strainer
Material: ASTM A105 (Forged Carbon Steel)
- General Description
This Y‑pattern strainer is designed for 1-1/2″ (DN40) Class 800 service. The forged ASTM A105carbon steel body provides high strength and reliability for high‑pressure applications in oil & gas, petrochemical, power generation, and industrial fluid systems. The Y‑type configuration offers a low pressure drop while enabling efficient removal of pipeline debris, protecting downstream equipment such as pumps, meters, and control valves.

- الميزات الرئيسية
- Forged Carbon Steel Construction: ASTM A105 provides excellent mechanical properties, toughness, and reliable performance at elevated pressures and temperatures.
- Class 800 Rating: Designed for high‑pressure systems requiring superior strength and safety margins.
- Y‑Pattern Design: Angled screen chamber minimizes pressure drop and allows continuous flow even when the screen is partially loaded.
- Easy Maintenance: Bolted cover enables quick removal of the screen for cleaning or replacement without removing the strainer from the pipeline.
- Versatile End Connections: Available in flanged, socket weld, or NPT configurations to suit various piping systems.
- Optional Blow‑Down Connection: A tapped drain port can be provided for periodic flushing without cover removal.
- Magnetic Insert Option: Available for capturing ferrous particles in critical applications.

- ملحوظات
- Class 800 Note: Class 800 is not a standard ASME B16.5 flange class. It is commonly defined per ASME B16.34 for valves and often utilizes Class 600 or Class 900 flange dimensions. Confirm flange dimensions with the manufacturer.
- Installation: Ensure flow direction matches the arrow on the body. The screen should be accessible for periodic cleaning.
- Maintenance: Regularly inspect and clean the screen to prevent excessive pressure drop. Replace gaskets and bolts according to recommended torque values.
- Pressure Drop: For accurate sizing, refer to the manufacturer’s flow coefficient (Cv) and screen open‑area data.
