BRIEF INTRODUCTION
Precision Seamless tube

Precision pipe is a seamless steel pipe with high precision and high brightness produced through cold drawing or cold rolling processes. Its inner and outer diameter dimensions can be precise to within 0.2mm, ensuring bending and torsional strength while also being lightweight, making it widely used in the manufacturing of precision mechanical parts and engineering structures.

We can supply various materials and specifications of cold-drawn and cold-rolled seamless steel pipes with an outer diameter of 10-140mm and a wall thickness of 2-15mm, with an annual production capacity of 300000 tons. The products are widely used in various fields such as petrochemicals, boilers, automobiles, machinery, construction, electricity, ships, etc.
