Duplex Strainers

Duplex Strainer


A duplex strainer is a specialized strainer that is for use in critical applications that uses two inline strainers with a flow diverter.

This allows for one strainer to be in use at all times, while the other strainer is cleaned, repaired, replaced, or waiting to be put into service. These strainers will most frequently have flanged connections.

Hendrix Fabrication’s duplex strainers can be fabricated in a wide range of materials like Carbon Steel and different grades of Stainless Steel with sizes ranging from 2” up to 72”.

They can be manufactured and rated from 150# to 2,500# ANSI with either flanged or quick opening closures.
