Temporary Cone Strainers for Pipeline Commissioning

Temporary cone strainers, nicknamed witch hat strainers due to their pointy-end design, are the most versatile style for temporary strainers because they can be installed with the narrow end with or against the pipeline flow.  The typical installation is orienting the pointy end against the pipeline flow, causing particulate to gradually build-up around the circumference of the pipeline.  They are also used to capture particulate with the highest straining ratio possible for a given pipeline size.  We can provide temporary cone strainers for 150# and 300# pipelines from 3/4" to 24" in size made of carbon steel, 304LSS or 316L SS.  The standard perforation is 1/8", although we can supply with other perforation sizes as well as with mesh lining. 

Mesh lined temporary cone strainers retain finer particulate and the mesh is always located on the upstream surface, thus  the underlying perforated substrate sully supports the delicate mesh lining.  Standard mesh lining sizes are 20, 30, 40, 50, 60, 80, 100, 150 and 200. 

The standard open area ratios are 100% or 150%, we can provide proposals for longer elements as required.
