Abstract
The utility model relates to an internal anti-corrosion pipe, in particular to a high-performance internal anti-corrosion composite pipe. The high-performance internal anti-corrosion composite pipe is characterized by comprising at least two layers, wherein the outer layer is made of steel pipes, and the inner layer is made of polyurethane elastic material. The composite pipe provided by the utility model can be used for replacing the steel pipes to be applied in relevant fields such as chemical engineering, is very good in corrosion resistance and provides good wear resistance.
Description
Technical field
The utility model relates to a kind of internal corrosion-proof pipe material, is that the utility model relates to a kind of internal corrosion-proof pipe material specifically, is anti-corrosive composite pipe in a kind of high-performance specifically.
Background technique
Steel pipe has irreplaceable effect with its superior characteristic in many industries.But when being applied to association area such as chemical industry, various transport materials can cause the corrosion of steel pipe, and this has seriously reduced the working life of steel pipe, and cost is improved.Therefore be badly in need of seeking durable novel steel tube.
The model utility content
The model utility purpose:
The utility model is intended to change a series of problems of being corroded in the steel pipe using process, through being cast in liner one deck polyurethane anticorrosion protective layer in the steel pipe in rotating.
Technological scheme
Anti-corrosive composite pipe in a kind of high-performance, it is two-layer at least to it is characterized in that said tubing comprises, and skin is a steel pipe, and internal layer is a polyurethane elastomeric materials.
Also be provided with the mesosphere as a kind of optimal way, described mesosphere is adhesive or thermal insulating material.
Also be provided with thermal insulation layer as a kind of optimal way steel pipe skin, described thermal insulation layer is a thermal insulating material
Described steel pipe inner wall smooth degree of one-tenth is irrelevant.
Described polyurethane anticorrosion protective layer and steel pipe bonding are good.
Described polyurethane anticorrosion protective layer can reach different thickness as required, and uniform in thickness.
Described polyurethane anticorrosion protective layer is the regular cylinder annular that links to each other with steel pipe, smooth surface, pore-free.
Described polyurethane anticorrosion protective layer can carry out the multilayer cast as required, the material of required cast, and layering, thickness etc. are control as required all.
Described polyurethane elastomeric materials is a cast polyurethane glue; Adhesive can epoxy resin, polyurethane resin; Described thermal insulating material can be asbestos, polyurethane.
Described polyurethane elastomeric materials, adhesive, thermal insulating material are the production of Jiangsu Si Taida new energy development in science and technology Co., Ltd or provide.
Beneficial effect
The composite pipe that this patent provides can replace steel pipe to be applied to association areas such as chemical industry, has very good decay resistance, and good abrasion resistance is provided.
