Product Description

Product Introduction

Cold rolled seamless steel tube

cold rolled seamless steel pipe is used for the mechanical structure, hydraulic equipment, which is have precision size, good surface finish. It can greatly reduce mechanical processing hour and improve material utilization, and to improve the quality of products. In addition to ensure chemical composition and mechanical properties, it will check by Hydrostatic test, crimping, flared and Squashed test.

Precision seamless pipe is a pipe material producing by a cold drawn or cold rolled process with high precision and high-quality finish. Due to the characteristics of high-precision, in precision machinery manufacturing, auto parts, hydraulic cylinders, construction (steel sleeve)industry has a very wide range of applications.
