Material Specifications - Lined Pipe & Fittings

The materials that CRP use to manufacture lined piping can be broken down into 3 groups, Carbon steel materials, Stainless steel materials and the fluoropolymers lining materials. The lining materials used by CRP are always sourced directly from global manufacturers and are the same types whether lining carbon or stainless steel piping and fittings.
We have tried to standardise on steel castings and PFA mouldings to give highly dimensionally accurate components and even liner wall thicknesses, our standard range of piping and fittings are designed to suit B16.5 Class 150 piping systems, however we do manufacture products to suit other piping classes.
