Conical strainers are preferably used. The cone is a perforated metal lined by a wire mesh (fine or coarse).

1) Fine mesh: Wire mesh from 60mesh to 300mesh

2) Coarse mesh: Wire mesh from 10mesh to 50mesh

The free mesh area of the conical strainers must be equivalent to at least 3 time the cross section of the pipe to avoid excessive resistance due to foreign objects caught in the strainer.

Strainer type selection should be according to your specific requirements. A general guideline as follows:

1) Temporary service for start-up of piping systems and permanent compressor packages, permanent service in clean natural gas applications. Temporary cone and basket strainers are suitable for the above requirement.

2) Low flow & small pipe Size,temporary service only. Flat strainers are suitable for the above requirement.
