Fabricated Temporary Strainer

Hellan Temporary (Geometric) Strainers may be installed between flanges in a pipeline.  Designs include cone, truncated cone, and flat geometrics.  Normally temporary strainers are used for startup of a new piping system.  However frequently they are left in the line during operation.  As with all strainers, periodic maintenance must be carried out for efficient operation.

Designed with 100% to 300% open area range (OAR) as standard, using stainless, carbon steel, monel, and hastelloy materials.  End connections are available with wafer flat faced, raised face, or ring type joint inlets in sizes from 3/4″ to 24″.  Other materials, sizes and OAR conditions are available up on request.  Pressure ranges up to 3,600 PSIG at 800 degrees F.   Multiple flow options are available for each design, including inside to outside, outside to inside and bidirectional.
