Since these are low carbon materials, they need to be preheated before welding. The preheating allows the ASTM A333 Pipe to have enough ductility to not to develop welding cracks. The applications of the pipes are seen primarily in the oil and gas industry, petroleum industry and in oil and gas transmission lines. They are also found in structural applications such as the construction industries. Please feel free to contact us for more information on the A333 Grade 6 Seamless Pipe and the pricing.
