Description
Technical field
The utility model relates to steel pipe processing technique field, specially a kind of wear-resisting plastic coated composite steel pipe of resistant to rust.
Background technique
Plastic-coated steel also known as plastics coated tube, steel-plastics composite pipe, plastic coated composite steel pipe, be using steel pipe as matrix, by spray, rolling,
Leaching inhales technique in one layer of plastic anti-corrosion layer of steel pipe (bottom tube) inner surface welding or in the steel modeling of surfaces externally and internally welding plastic erosion resistant coating
Composite steel tube.Plastic-coated steel has excellent corrosion resistance and smaller frictional resistance.Epoxy resin plastic-coated steel is suitable for
The conveying of the media such as plumbing, seawater, warm water, oil, gas, polyvinyl chloride plastic-coated steel are suitable for draining, seawater, oil, gas
The conveying of equal media.
Currently, plastic-coated steel uses mild steel mostly, surface is easy to wear in processing or use, the steel tube surface after abrasion
It can get rusty, and then influence the service life of steel pipe.
Utility model content
The utility model provides a kind of wear-resisting plastic coated composite steel pipe of resistant to rust.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of wear-resisting plastic coated composite steel pipe of resistant to rust, including steel pipe body, the steel pipe body include outer base tube and liner
Pipe, the outer base tube are coating steel pipe, and internal lining pipe is stainless steel tube, and elastomeric state rubber is filled between the outer base tube and internal lining pipe
Glue packing layer, the elastomeric state gum filler layer is interior to be equipped with clathrum, and the outside of the outer base tube is equipped with nitriding layer, the nitriding
The outside of layer is equipped with multi-layer vapor deposit, and the outer application of the multi-layer vapor deposit has rust-proofing dope layer, the liner
The inner wall welding of pipe is connected with plastic anti-corrosion layer.
Further, the clathrum is entwined for fiberglass gridding cloth.
Further, the end of the steel pipe body is equipped with connecting flange, is equipped with corrosion-inhibiting coating on the outside of the connecting flange.
