The Fig 34 is an integrally flanged Y-type strainer designed to remove
rust, scale and other debris from the pipeline. It is produced from
carbon steel, ASTM material.
The standard stainless steel screen in the DN15 to DN80 is 0.8 mm
perforations and in the DN100 to DN200 it is 1.6 mm perforations.
NB: A low temperature carbon steel strainer is available on request.
This product fully complies with the requirements of the European
Pressure Equipment Directive 97/23/EC.
