Abstract
The invention relates to a process method for manufacturing a steel frame reinforced nylon pipeline. Currently, when a material with high grindability is transported in the pipeline, pipeline abrasion is generated, particularly the bent pipe abrasion, is more prominent. When strong corrosive gas, liquid or solid is transported, the problem of eroding and damaging the pipeline occurs. In the method, a graticule cylinder metal framework woven and coiled by deformed steel bars is embedded into the middle part of a nylon pipe which uses reinforced composite nylon (RMC) and reinforced nylon (MC) as raw materials; and the winding and coiling of the deformed steel bars and high-temperature polymerization reaction of nylon for extrusion are performed synchronously. The steel frame reinforced nylon pipeline is manufactured so as to overcome the disadvantages of a conventional pipeline. The process method has the advantages of high anticorrosion, high wear resistance, tensile resistance, pressure resistance, light weight, convenient construction and the like.
