Production Process Production Flow Chart

Raw steel

we purchase raw steel according to the production needs, including 20Crmo, 30Crmo, 20Cr, 40Cr, 20Mn2, 422Crmo, Q345b, Q345d and so on.these materials are also coming from top steel factory in our country.like Henan Jiyuan Iron and Steel (Group) Co., Ltd;Tianjin Iron and Steel Group Co., Ltd;Huai Steel Group;Hegang Group Stone Steel Company .

Cutting The Material

our workers cut the raw steel according to the production control plan which is made by our professional technical staffs.

Perforating

Pouring workshop heating inclined furnace, according to the steel grade steel tube, using different heating temperature and heating time for production. Punch unit includes 50 enhanced automatic punching machine and one 40 automatic punching machine, to meet a variety of wear specifications

Acid pickling,phosphating and saponification

By controlling the acid tank temperature and concentration, control the quality of the product during the pickling process;
By controlling the concentration, temperature and freeness of the phosphorus cylinder, the surface quality after phosphating can be controlled.
By controlling the saponification tank temperature and freeness, fatty acid content, control saponification of product quality.

Cold drawn or cold rolled

By selecting the appropriate mold, cold drawing/cold rolling the desired size, sometimes require multiple drawing/rolling.

Heat treatment

our company equipped with normal annealing furcace and Anaerobic annealing furnace to satisfy different request about the steel pipe.

Straightening

finishing and straightening the steel pipe

Cutting the pipes
