2. STRAINERS

Strainers are generally constructed of finely perforated metal tubes or cones or of woven wire mesh. They are often used temporarily after new piping has been installed or maintenance carried out on a process system. Their purpose in this case is to remove debris such as welding dross or pieces of solid material which entered the system while the work was being done.

Where small piping like fuel supplies, air to instruments and steam / condensate systems are concerned, strainers are installed to ensure the smooth operation of instruments and steam traps by removing solid particles.

The main types of strainer used in such systems are :

  1. THE 'Y' STRAINER.
  2. THE 'T' STRAINER
  3. THE 'CONE' STRAINER.

The following diagrams show the application of strainers in process operations.
