Description

Technical Field

[0001] The present application relates to the field of RTP pipes, and in particular to super wear-resistant RTP pipes. Background Art

[0002] RTP pipe is a new type of flexible medium- and high-pressure environmentally friendly composite pipe formed by combining polymer materials such as PE, PVC, PP, PB with a variety of high-strength fibers. The density is only one-sixth of that of steel, and the tensile strength can reach several times that of steel. It has the characteristics of high mechanical strength, non-toxic and odorless, corrosion resistance, high pressure resistance, light weight, good toughness, and not easy to scale. It is used in environments such as the seabed, deep wells, deserts, ocean currents, goafs, and collapsible loess areas. It has good high-pressure resistance, corrosion resistance, and impact resistance. It can be widely used in water conservancy, municipal administration, petroleum, gas, coal, chemical industry and other industries for water, oil, gas, brine, hydrogen, emulsion, alcohol injection and other corrosive fluid transportation operations.

[0003] The innermost layer of the existing RTP pipe is usually an inner lining layer made of ordinary polyethylene. Polyethylene has a certain wear resistance, but the Mohs hardness of polyethylene is only about level 2. In the mining industry, especially for pipeline systems used to transport pipelines containing solid particles (such as slurry), slag can easily enter the interior of the pipeline. The hardness of slag is usually high, and the slag can easily scratch the inner wall of the RTP pipe, which can easily affect the flow rate and service life, making it inconvenient to use.
