Product Introduction

4140 Steel Pipe is a seamless steel pipe for machinery under ASTM A519.

The seamless steel pipe products for mechanical processing take the tube billet (mainly the continuous casting billet) as the raw material, and after heating, they are rolled into steel pipes by centering, piercing, continuous rolling, and tensioning units. At the same time, the supporting pipe ends are thickened and pipe joints are processed. , Tool joint processing, heat treatment, ultrasonic, magnetic flux leakage, eddy current, magnetic particle online flaw detector and spectrum, hardness testing machine and other production equipment to meet the various requirements of different users. The annual output has exceeded 600,000 tons, the outer diameter of the product is 8~720mm, the wall thickness is 2.5~40mm, including casing, oil pipe, drill pipe, low, medium and high pressure boiler pipe, marine pipe, train and automobile pipe, fluid structure pipe And cold drawing deep processing tube materials and so on.
