Cold Drawn Seamless Steel Pipe
Introduction of Cold Drawn Seamless Pipe:
In order to produce the smaller size and better quality seamless steel pipe, the two methods of cold rolling and cold-drawing should be combined. The cold rolling process is conducted on the twin rolling mill, while the steel pipe is rolled in the round hole.
The cold-drawing is conducted in the cold-drawing machine with 0.5～100T single or double roller chain.
The raw material of cold drawn seamless steel pipe is hot rolling seamless circular pipe.

The cold drawn seamless steel pipe is applied in accordance with the specific circumstance of each customer. For fear of rusting in the long time ocean shipping, the exporting pipe is required to paint the antirust paint, normally, the paint is black.
Packing and Shipping:
The small pipe size steel is packed in bundle while others are packaged according to the customer's requirements. The inland transportation mode is motor, while the overseas is sea transportation with containers.
