Abstract

The invention discloses a steel wire wound flexible pipe, which comprises a pipe body, and is characterized in that the pipe body is compounded by multiple layers, the multiple layers comprises a modified nylon 6 layer, a polyurethane layer, a steel wire braid layer and another polyurethane layer from inside to outside in sequence. The steel wire wound flexible pipe comprises the inner layer and outer layer of modified nylon 6 layer and a polyurethane layer as well as the steel wire braid layer in the middle, so that the steel wire wound flexible pipe has good rigidity and toughness as well as good oil resistance and wear-resisting property, and has long service life.

Description

technical field [0001] The invention relates to a pipeline, mainly a steel wire winding hose. Background technique [0002] In the high-pressure transmission of the automobile industry, construction machinery, lifting and transportation machinery, and some high-pressure special pipes, the pipelines are required to have good oil resistance, acid and alkali resistance and aging resistance, and good toughness is required. General fiber hoses are not suitable. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel wire wound hose, which has inner and outer layers of modified nylon 6 and polyurethane, and a steel wire braided layer in the middle, so it has good rigidity and toughness, and at the same time, it has good oil resistance and wear resistance ,long lasting. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A...
