Problems solved by technology

The pressure and wear resistance of some existing insulation pipes is not good enough. When subjected to external pressure or dragging, the pipe body is easy to crack and cause leakage. Moreover, the outer side of the insulation pipe is more stressed, and it is easy to delaminate with the inside, which affects the use of the insulation pipe ,Room for improvement

Abstract

The invention relates to a wear-resistant and pressure-resistant type heat preservation pipe. The wear-resistant and pressure-resistant type heat preservation pipe sequentially comprises an inner steel pipe, an inner heat preservation layer, a heating layer, a buffering layer, an outer heat preservation layer, a reinforcing layer, a waterproof layer, a corrosion-resistant layer and a wear-resistant layer from inside to outside, a plurality of heating pieces are arranged in the heating layer, a plurality of buffering balls are arranged in the buffering layer, and the inner sides and the outer sides of the buffering balls are abutted with the heating layer and the outer heat preservation layer respectively. According to the wear-resistant and pressure-resistant type heat preservation pipe, the pressure-resistant and wear-resistant of the heat preservation pipe are enhanced, a pipe body is not prone to cracking, leakage is avoided, the outermost layer of the heat preservation pipe is connected with the inner side through convex teeth, the outer layer is prevented from being separated from the inner layer, fastening rings can prevent all layers in the inner part from being separated ina layered mode, and the quality of the heat preservation pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a wear-resistant and pressure-resistant heat preservation pipe. Background technique [0002] Insulation pipe is the abbreviation of heat insulation pipe. The heat preservation pipe is used for the transportation of liquid, gas and other media. The pressure and wear resistance of some existing insulation pipes is not good enough. When subjected to external pressure or dragging, the pipe body is easy to crack and cause leakage, and the outer side of the insulation pipe is more stressed, and it is easy to delaminate with the inside, which affects the use of the insulation pipe ,Room for improvement. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art and provide a wear-resistant and pressure-resistant insulation pipe. [0004] In order to achieve the above object, the present invention adopts the following technical solutions...
