PVC-Coated Pipe
Thin-wall stainless steel pipe with protective PVC coating for buried and insulated water systems.
Product Overview
PVC-coated stainless steel pipe combines a food-grade thin-wall stainless steel carrier tube with a factory-applied PVC outer layer. The coating is tightly bonded to the steel surface and protects the pipe from corrosion in buried, humid or exposed environments, while the stainless steel inner wall keeps the water path clean and hygienic.
For buried service lines up to DN100, the factory-coated pipe is recommended to avoid on-site anti-corrosion work; for insulation applications up to DN150, PE-foam insulated coated pipe is available.
