Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between CCSA bulk freighter steel, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
