Duplex Strainers

Strainers

Duplex Strainers

These strainers can be fabricated to any specifications. Carbon steel and stainless steel bodies are available Flanged off line connections are std. . However inline strainers can be supplied on request. Covers are similar to simplex basket strainers these strainers have been designed to answer the specific need for continuous operation. Duplex arrangement ensures that when one strainer chokes the flow gets diverted through another strainer and the choked strainer can be cleaned and ready for use when the next strainer chokes. Free straining area is minimum 6 times pipe CS area.

Applications:

1. Pump protection

2. Flow meter protection

3. Protection of steam traps

4. Valve and regulator protection

5. Protection of heat exchanger and refrigerating set

6. Instrumentation and ancillary piping item protection
