Production Process

Different processing methods and corresponding auxiliary procedures are selected according to the processing performance of the metal, the size of the pipe, the quality requirements, and the investment and benefits. The basic processes of cold-rolled and cold-drawn pipes are:

(1) pipe material supply, the pipe materials used are hot-rolled finished pipes or semi-finished pipes, extruded pipes and welded pipes;

(2) pipe material preparation, including inspection, bundling, acid Washing, cleaning, rinsing, neutralizing, drying, lubricating, etc.;

(3) Cold working (cold rolling or cold drawing);

(4) Finishing of finished products includes heat treatment of finished products, straightening, sampling, cutting heads and tails, inspection ( Manual inspection and various flaw detection), hydraulic test, oiling, packaging, storage, etc. Different products have different finishing contents.
