Material

Delivery condition

Cold drawn/cold rolled precision seamless steel pipe is used for the mechanical structure, draulic 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. High quality of cold draw seamless steel pipe are mainly use the 10# 20#. In addition to ensure chemical composition and mechanical properties, it will check by Hydrostatic test, crimping,flared and Squashed test.
