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.

주요 특징

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.

노트

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.
