Plastic pipe and plastic lined steel pipe has what difference?
Definition: lining plastic pipe is based on steel pipe, the inner and outer surface has been treated, galvanized with paint or spray paint, lined with polyethylene plastic or other lining plastic steel composite products.Classification: plastic lined steel pipe cold water and hot water pipe lined with plastic lining plastic pipe, plastic lining plastic pipe
Installation construction: in the course of construction and installation, the lining plastic pipe can not be cut for the plastic lined steel pipe on the spot because of the construction technical change. Increase construction difficulty and cost. The on-site construction of the plastic lined steel pipe can not be prefabricated in advance and prolong the construction time. The lining of the plastic pipe will produce a shrinkage phenomenon (relative), which will increase the design pressure of the piping system. Lining plastic pipe because lining plastic relatively thick, relatively wear-resistant.
Lining plastic process: after the steel pipe is processed, the adhesive is evenly coated on the outer wall of the plastic pipe, and then the steel plastic composite product is expanded in the steel pipe to expand.Rotomold: steel before processing after heating, while rotating the pipe, the polyethylene powder evenly sprinkled on the ground on the inner wall of the steel plastic composite products and then curing treatment and the formation of.
