Precision steel pipe

Precision steel pipe is a seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling process

The size of the inner and outer diameters can be accurate to within 0.1mm, while ensuring the same bending and torsion strength, the weight is relatively light, so it is widely used in the manufacture of precision mechanical parts.

Comparison of implementation standards home and abroad

National standard: GB/T 3639-2009 cold-drawn or cold-rolled precision seamless steel pipe implementation standard specification.

European Standard: EN 10305-1 standard specification for precision steel pipes and seamless cold-drawn steel pipe.

German standard; DIN 2445-2 cold-rolled precision steel pipe product implementation code.

Characteristic of precision pipe

Precision steel pipes can save waste of raw materials, improve machining efficiency, reduce processing procedures, increase production and material utilization, and at the same time help improve product quality and reduce costs, which is important for improving economic benefits
