Temporary strainer

A Temporary Strainer is a high-performance filtration device designed for short-term or start-up use in piping systems to capture debris, weld slag, and other solid contaminants during pipeline commissioning or maintenance.

Constructed from ASTM F316 stainless steel, this strainer offers excellent corrosion resistance and durability in demanding industrial environments. The wafer-type design allows for compact installation between standard flanges, while the 8-inch diameter and 600LB pressure rating make it suitable for high-pressure applications in oil, gas, petrochemical, and marine systems.

Product Description

Product Details

It effectively protects downstream equipment such as pumps, compressors, and valves from potential damage caused by foreign particles, ensuring smooth system start-up and operation.

Specifications:

Size: 8 inches (DN200)
Pressure Rating: Class 600 (PN100)
Material: F316 (Forged 316 Stainless Steel)
Connection Type: Wafer Type (between flanges)

Key Features:

Design: Conical or cylindrical perforated plate/mesh construction.
Function: Designed for temporary use during pipeline startup, flushing, or commissioning to capture welding slag, rust, scale, and other construction debris from the media .
Material Advantage: F316 offers superior corrosion resistance and high-temperature strength compared to carbon steel or 304 stainless steel, ideal for harsh or chemical environments .
Installation: Installed between two flanges (Wafer type). Requires gaskets on both sides to ensure seal integrity .
Maintenance: Once the system is clean, the strainer element is removed via the pressure seam (or it is removed from the flange connection) after system shutdown; no permanent modification of the pipeline is required .

Applications:

Chemical plants
Oil & gas pipelines
Power generation (steam/water lines)
Pre-commissioning of pump suction lines
