CHEMICAL RESISTANT PROCESS EQUIPMENT AND METHOD OF PRODUCING PROCESS EQUIPMENT

摘要

Chemical-resistant fiberglass reinforced plastic process equipment enclosing an open area is produced by helical winding, centrifugal casting, or the like. The equipment includes a primary corrosion barrier formed by an inner surface of resin with a reinforcing fabric, an interior layer, and an exterior layer. The reinforcing fabric comprises a chemical-resistant polyester non-woven surfacing fabric having interlocked fibers characterized by a fiber-interlock value due to fiber entanglement of at least 7 with a fiber entanglement completeness of at least 0.5, the values being determined in the absence of a binder. This non-woven fabric may also be used as the interior layer, both with a conventional inner surface or non-woven fabric backed inner surface, or as an overwind for the exterior layer.
