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.
