Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Examples
Referring to fig. 1-2, a multilayer composite pipe includes a medium transmission layer 1, a reinforcing layer 2, a reinforcing layer protection layer 3 and an outer cladding layer 6, wherein the reinforcing layer 2 is wrapped outside the medium transmission layer 1, the reinforcing layer protection layer 3 is wrapped outside the reinforcing layer 2, an isolation layer 4 and a steel skeleton protection layer 5 are arranged between the reinforcing layer protection layer 3 and the outer cladding layer 6, the isolation layer 4 is wrapped outside the reinforcing layer protection layer 3, and the steel skeleton protection layer 5 is located between the isolation layer 4 and the outer cladding layer 6;
in order to improve the bearing capacity of the reinforcement layer 2, the reinforcement layer 2 is made of steel wires;
the medium transmission layer 1 and the outer coating layer 6 are both made of polyethylene;
the reinforcing layer 2 and the steel skeleton protective layer 5 are formed separately, when the reinforcing layer and the steel skeleton protective layer are damaged by external force, the steel skeleton protective layer 5 can well protect the inner reinforcing layer 2, and the steel skeleton protective layer 5 cannot influence the integral bearing performance of the multilayer composite pipe even after being damaged, so that the normal function of the multilayer composite pipe is ensured;
the isolation layer 4 is made of a copolymer elastic adhesive tape, can play a supporting role when the multilayer composite pipe is wound and expanded under pressure, and meets the requirement of deformation during expansion through certain elastic deformation.
The multilayer composite pipe greatly improves the tensile compression resistance and bending resistance of the pipe body by additionally arranging the isolation layer 4 and the steel skeleton protection layer 5, and meanwhile, the outer coating layer 6 is made of polyethylene and is more wear-resistant; the construction is simple and easy, the maintenance is convenient, the safety factor is high, the application range is wide, and the development prospect is good.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
