Seamless BA Stick tube

After the steel pipe is rolled and cold drawn, it is heat treated in a protective gas or vacuum state to prevent the oxidation and decarburization of the surface of the steel pipe and maintain the bright state of the surface finish, also known as BA straight pipe.

Seamless Long Coil tube

After the mother pipe is rolled and cold drawn, it is a steel pipe produced in a circular coil shape. In order to increase the fold rate of the product and facilitate the transportation of the products produced in the form of coils during cold processing.
