Precision seamless steel tube is a kind of high precision steel tube after cold rolling or cold drawing.Full name: cold rolled or cold drawn precision seamless steel tube.Because the inner and outer wall of the precision seamless steel tube has no oxide layer, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other advantages, it is mainly used for the production of pneumatic or hydraulic components of products, such as cylinder or oil cylinder, are seamless pipe.

The precision seamless pipes produced by Changzhou Chuangcheng Precision steel Pipe Factory are mainly used in the following fields:

1. For furniture, air spring pipe for cabinet door and air bar pipe for office chair

2. Pipeline for construction machinery, excavators and related equipment

Shock absorbers for cars and motorcycles

4. Mechanical processing

Cold drawn seamless steel tube:

○ The inside and outside surface finish is good

Mechanical performance is better than hot rolled pipe

Short production cycle and large output

○ The price is relatively low

Cold rolled seamless pipe:

○ Has a high precision size, ±0.05mm

○ Smooth surface, good finish;High inner wall cleanliness
