Suppliers of FRP piping and tanks have been called FRP Fabricators, forever. I think this comes from the early days when fabricators built anything and everything from tanks to pipes to washer hoods to feed troughs. Today, the FRP industry is much more refined in many ways.
Modern FRP manufacturing requires rigorous quality control, qualified resin systems, strict laminate sequence adherence, and specialized curing protocols that go far beyond basic hand lay-up fabrication.
Understanding the distinction between an experienced FRP manufacturer and a general fabricator is critical for plant engineers seeking reliable equipment built to stringent standards like ASME RTP-1 and NBS PS 15-69.
