Problems solved by technology

The various types of pipes commonly used today generally have problems such as single function, limited performance or high cost, so it is particularly important to develop new high-performance composite pipes
[0003] At present, the materials used in wear-resistant pipelines mainly include wear-resistant polymer materials, ceramic materials and metal materials. Among them, polymer materials have general wear resistance and short life; ceramic materials are more complicated to process, fragile and non-ductile; Metal materials for wear-resistant pipes are generally added with rare and precious metals such as chromium and molybdenum, which greatly increases the production cost
Therefore wear-resistant pipes in the prior art all have certain shortcoming or limitation

Abstract

The invention relates to a multilayer composite pipeline, which is provided with an inner layer, a middle layer and an outer layer, wherein the middle layer is an elastic layer, the outer layer is mainly made of hard plastics, the inner layer and the middle layer are fixed in a bonding manner, and the middle layer and the outer layer are also fixed in a bonding manner. The composite pipeline is low in cost and convenient in processing, and has wear resistance, corrosion resistance and impact resistance.

Description

technical field [0001] The invention relates to a multilayer composite pipeline, in particular to a low-cost, wear-resistant, corrosion-resistant and impact-resistant multilayer composite pipeline. Background technique [0002] In modern industry, pipes have been widely used. In industries such as electric power, cement, mining and steel, abrasion resistant pipes are especially required. Such as power plant ash and fly ash are transported through wear-resistant pipelines on the production line. However, due to the complexity of the application environment, higher and higher requirements are placed on the performance of pipeline materials. Today's common types of pipes generally have problems such as single function, limited performance or high cost, so it is particularly important to develop new high-performance composite pipes. [0003] At present, the materials used in wear-resistant pipelines mainly include wear-resistant polymer materials, ceramic materials and metal ...
