1″-600LB A105 Y Pattern Strainer
Description
TECHNICAL DATA SHEET
Product: 1″ – Class 600 Y‑Pattern Strainer
Material: ASTM A105 (Forged Carbon Steel)
1. General Description
This Y‑pattern strainer is designed for 1″ (DN25) Class 600 service. The forged ASTM A105 carbon 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.

4. Key Features
-
Forged Carbon Steel Construction: ASTM A105 provides excellent mechanical properties, toughness, and reliable performance at elevated pressures and temperatures.
-
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.
5. Screen Options
| Type | Description | Typical Application |
|---|---|---|
| Perforated Basket | 0.5 mm – 3.0 mm hole diameter | Coarse straining, high flow, low pressure drop |
| Mesh Liner | 20 – 200 mesh (stainless steel) | Fine filtration of particulates |
| Dual Layer (Perforated + Mesh) | Combines strength with fine filtration | General purpose, demanding applications |

10. Notes
-
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.
