Wide Type Strainer
Wide Type Strainer is a wide-body / basket-type strainer used to remove solid particles and debris from pipeline flow. Its large filtration area offers low pressure drop and easy screen removal, protecting pumps, valves, and downstream equipment from damage in water, cooling water, HVAC, and industrial process lines.
Introduction
A wide type strainer is a basket-style filtration device installed in pipelines to remove solid particles and debris from the fluid stream. Its wide body and large screen area provide low pressure drop and high debris holding capacity.
Key Features
- Basket, Y-Type, or Wide-Bodied strainer construction.
- Stainless Steel (SS 304 / SS 316) or Duplex screen.
- Perforation level as per required filtration requirement.
- Drain plug / drain valve arrangement for easy cleaning.
- Bolted or quick-opening cover.
- Large filtration area with low pressure drop.
- Easy screen removal for maintenance.
- Flanged, wafer, or lug end connections.

Application & Usage of Wide Type Strainer
Pump Protection
Installed on pump suction lines to remove sand, scale, and debris that would damage impellers and seals.
Water & Cooling Water Systems
Filters raw and clarified water in intake and cooling circuits, protecting heat exchangers and nozzles.
HVAC Systems
Protects chilled-water and condenser loops from particulate contamination, maintaining coil and valve performance.
Process Lines
Placed upstream of control valves, flow meters, and instruments to prevent clogging and premature wear.
Irrigation Networks
Removes silt, sand, and organic debris from canal and pipeline water to safeguard downstream equipment.
Types of Strainers
Basket Strainer
Wide-body strainer with a large cylindrical basket screen, offering high debris capacity and easy removal for cleaning.
Y-Type Strainer
Compact strainer with a Y-shaped body and inclined screen, ideal for limited-space installations and fine filtration.
Wide-Bodied Strainer
Extra-large screen area design that minimizes pressure drop and maximizes holding capacity for high-flow services.
Certificates & Inspection
All valves are subjected to rigorous hydrostatic shell and seat pressure testing in accordance with standard codes (e.g., API 598 / IS 14846) prior to delivery.
- Physical dimension and wall-thickness checks
- Hydrostatic seat and shell test validation
- Manufacturer Test Certificate (MTC) and third-party inspection (SGS, TUV, RINA, IRS etc.) available
- Epoxy powder coating inspection (DFT test)
