Problems solved by technology

A single material cannot meet the comprehensive performance requirements for strength, toughness, wear resistance, corrosion resistance, and ease of processing. Therefore, new composite materials must be developed to produce pipes to meet the actual needs of various industries for pipe production.
At present, composite pipes are mainly divided into: steel-rubber composite pipes—the inner lining is made of pure polymer rubber, which is easy to deform and tear, and will cause pipe blockage in severe cases; self-propagating ceramic composite pipes—the factors affecting the preparation process of this product are relatively complicated. The quality controllability is poor, there are incomplete chemical reactions and environmental pollution problems in the preparation process, and because the overall ceramic lining layer is a brittle material, it is easy to cause the lining layer to break when it is hit during installation and use; disappear Vacuum-casting bimetallic pipes in die-casting—solved the problem that special-shaped pipes cannot be compounded, but heavy weight is the biggest defect of the pipes; ceramic sheets inside—preparing large-diameter pipes has certain advantages, but the preparation of small-diameter pipes is limited to a certain extent. restrictions, and the ceramic pieces are easy to fall during use; therefore, it is imperative to prepare a pipeline with light weight, low price, wide source of raw materials, good wear resistance, and various specifications

Description

technical field [0001] The invention belongs to mechanical equipment and a preparation process in the field of material transportation, in particular to a composite material-lined wear-resistant pipe and a preparation process thereof. Background technique [0002] In metallurgy, mining, electric power, building materials, refractory materials, energy and other industrial industries, materials are transported through long-distance and powerful pipelines. The pipelines are not only under considerable pressure, but also suffer from serious wear and tear. A single material cannot meet the comprehensive performance requirements for strength, toughness, wear resistance, corrosion resistance, and ease of processing. Therefore, new composite materials must be developed to produce pipes to meet the actual needs of various industries for pipe production. . At present, composite pipes are mainly divided into: steel-rubber composite pipes—the inner lining is made of pure polymer rubber...
