Cold drawn steel pipe production process
Nov 29, 2017

Cold-drawn steel pipe, cold-rolled steel pipe unit is cold-rolled, cold-drawn or cold-rolled and cold-drawn combination of cold-processing methods to produce a complete set of equipment portfolio is hot-rolled pipe or welded pipe for deep processing of the unit.
The company is located in:
According to the metal processing performance, pipe size, quality requirements and investment and benefits to choose different processing methods and the corresponding auxiliary processes. Cold-drawn cold-drawn tube of the basic processes are: (1) pipe material supply, the tube material used for the hot-rolled finished pipe or semi-finished pipe, extruded pipe and welded pipe; (2) pipe material preparation, including inspection, (3) cold working (cold-rolled or cold-drawn); (4) finished product finishing including finished heat treatment, straightening, sampling, cutting the tail, checking ( Manual inspection and a variety of testing), hydraulic test, oiled, packaging, storage and so on. Different product finishing content is different.
The company is located in:
Cold-processing pipe unit production is characterized by the tube material into the processing into finished products usually go through multiple cold deformation and produce work hardening, and thus the entire production process consists of a number of preparation processes and deformation processes, and has the characteristics of reciprocating cycle, and thus more processes , Long production cycle, large metal consumption, low production efficiency, the general scale of production are not large.
The company is located in:
The simultaneous configuration of cold drawing and cold rolling mills in the unit is advantageous for their respective advantages, especially for the production of high alloy steel tubes such as stainless steel and non-ferrous metal tubes, which are difficult to be deformed. Cold drawing machine has a single root and multiple straight tube pulling machine and tube pulling machine (see the tube extubation). When a single cold drawn pipe length of 50m, extubation up to a few hundred meters. Drawing machine tonnage minimum 30kN, maximum of 7000kN. Conventional cold rolling mill has two roll cold rolling machine and multi-roll cold rolling machine two.
