Materials & Performance Specifications

CRP manufacture and supply a very wide range of PTFE and PFA fluoropolymers lined piping, valves, sight glasses and sampling systems. Different products have different allowable operating ranges, both temperature and pressure / vacuum limitations must be known to ensure that the products will perform satisfactory on site.

Our experience is that many companies do not have a comprehensive specification for their lined equipment.  Or their specification discusses metal specification in great detail, but is somewhat lacking in specifying the fluoropolymers to be used.  We have prepared a basic template from which to create a site lined piping specification.  Please feel free to use it - download it here.
