Cold Drawn Seamless Tube

As a professional cold drawn seamless tubemanufacturer and supplier, EASTAI Hydraulic has beensupplying and exporting cold drawn seamless tubefrom China for over 15 yearsAny inquiries and problems please feel free to sendemail: jeff@east-ai.cn , we will reply you within 1working day.

Manufacturing Process

Cold drawn seamless tube and pipe are manufactured through a process that begins with piercing hot billets. This initial step is followed by rolling, which serves to decrease their diameter and simultaneously extend their length. The material is then meticulously passed through a die while being guided over a mandrel plug. This critical phase of the process ensures the achievement of precise dimensions and the correct gauge, encapsulating the core of the cold drawing technique.

Material: ST52, CK45, 4140, 16Mn, 42CrMo, 1020, 1026, 1045, E355, Stainless Steel 304/316, Duplex 2205, etc.
