(1) In the selection of materials, under the condition that the strength is guaranteed, choose materials with low hardness and good plasticity;

(2) The specifications of the steel pipe should be selected according to the specifications of the finished product to ensure that the elongation is between 20% and 40%; the elongation is too small, the strength of the surface of the finished product cannot be guaranteed, and it is too large, making drawing difficult ;

(3) There should be no serious defects such as pits, cracks, cracks, folds, scars, ellipses on the surface of the material;

(4) It is best to choose steel tubes placed 0.5~2a after hot rolling. The time is too short, the surface corrosion of the steel tube is shallow, the time is too long, the surface corrosion of the steel tube is too deep, these will lead to insufficient pretreatment of the surface of the steel tube, which will affect the surface quality of the finished product.

Applications :

Automobiles, motorcycles, electric power, machinery, hydraulic accessories, bearings, pneumatic components, oil cylinders, coal mines, transportation, boiler equipment, pipelines, engineering and other fields.
