What is the manufacturing process of high-precision cold drawn tubes?
What is the manufacturing process of high-precision cold drawn tubes?
A complete set of equipment for producing pipes using cold processing methods of cold rolling, cold drawing or a combination of cold rolling and cold drawing. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Different processing methods and corresponding processes are selected based on the processing performance of the metal, pipe size, quality requirements, 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, pickling, cleaning, rinsing, neutralization, drying, lubricant application, etc.;
(3) Cold working (cold rolling or cold drawing);
(4) Finished product finishing includes finished product heat treatment, straightening, sampling, head and tail cutting, inspection, hydraulic test, oiling, packaging, warehousing, etc. Different products have different finishing contents.
The production characteristic of cold-worked pipe units is that pipe materials usually undergo multiple cold deformations and work hardening from input to processing into finished products. Therefore, the entire production process consists of multiple preparation processes and deformation processes, and has the characteristics of continuous reciprocation. Therefore, there are many processes, a long production cycle, large metal consumption, low production efficiency, and generally a small production scale.
