Cold-drawn seamless steel pipe

Cold drawn seamless steel pipe is a seamless steel pipe produced by cold drawing process, which has the following characteristics and advantages:

High dimensional accuracy：General accuracy isAbout 20 threads, it can achieve very high dimensional accuracy requirements and can be used in mechanical processing and parts manufacturing fields that have strict dimensional tolerance requirements.

Good surface quality: After multiple surface treatment processes, the inner and outer surfaces of the steel pipe are smooth, without defects such as cracks, folds, rolling, delamination, hairline and scars, and the appearance quality is excellent.

Excellent mechanical properties：Through cold working hardening, the strength and hardness are improved, while maintaining good toughness, it can withstand greater pressure and tension, and is suitable for various structures and equipment with high strength requirements 。

Uniform wall thickness: During the cold drawing process, the inner and outer diameters and wall thickness of the steel pipe can be accurately controlled to ensure the uniformity of the wall thickness, which is crucial for some industries that have strict requirements on pipe wall thickness, such as aerospace.
