The production of wear-resistant plastic alloy composite pipe mainly goes through the following processes:
First, the production of the outer wall steel pipe: the production of the outer wall steel pipe must go through the processes of blanking, welding, rust removal, etc., and only after passing the inspection can it enter the next process;
Second, the production of lined plastic alloy steel pipe: the production of lined pipe must go through a series of processes such as batching, processing, granulation, feeding, mixing, extrusion, vacuum setting, spray cooling, traction cutting, etc. Out of plastic alloy pipes. After passing the inspection, it can enter the next process;
The outer wall steel pipe and wear-resistant plastic alloy pipe that have passed the acceptance are now through the processes of reducing the diameter of the lining pipe and flanging to form a plastic alloy composite wear-resistant pipe. After the plastic alloy pipe is closely combined with the outer wall steel pipe, it undergoes anti-corrosion treatment and paint. After the acceptance is qualified, the plastic alloy composite pipe can be packaged and shipped out.
