Seamless Cold-Drawn Carbon Steel Feedwater Heater Tubes

We are manufacturer of Seamless Steel Tubes in China, if you want to buy Seamless Carbon Steel Tube, Oil Cylinder Steel Tube, Precision Seamless Steel Tube, Hydraulic Cylinder Steel Tube, please contact us.

A556/ A 556M-96 is a standard applicable for Seamless Carbon Steel pipes which is produced by cold-drawn and used for feed water heater.

Seamless Cold-drawn Carbon Steel tubes For Feed water Heater, made according to the American National Standard A556/ A 556M-96.

Standard: A556/ A 556M-96

Manufacture: Tubes is made by seamless process and cold drawn

Heat treatment: Cold drawn tubes shall be heat treated after the final cold-draw pass at a temperature of 640℃ or higher to ensure ductility satisfactory for rolling into tube sheets and to meet mechanical properties as specified.
