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.
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.
