Hot Rolled Petrochemical Piping , Carbon Steel Seamless Pipes ASTM A106 Gr B

Since A106 seamless can be hot finished or cold drawn, in very, very basic terms the difference between the two is a matter of the temperature at which the process is performed. Hot finished pipe is produced at temperatures over about 1700F° while cold drawn is produced at much lower temperatures and with more processing. For OD<325mm pipes, we use hot rolled method.

TIPTOP has been supplying ASTM A106 Gr. B pipes to various petrochemical projects like Santos GLNG Upstream project, Russian Silican Acid project, fertilizer plant, etc.
