I would like to ask the experts: what standards are followed for the filter elements of chemical process pipelines? A T-type straight-through filter in our factory has a damaged filter element, and we want to manufacture a new one; I’m not sure which standards should be applied. Thank you~

Guys upstairs, HG/T 21637 is already in its 2021 version; the 91 version is obsolete now

There is no standard for filter elements, unless they are standard parts provided by the manufacturer.
