Seamless Steel Pipe is able to withstand high pressures, they are also widely used in high-pressure applications including refineries, hydraulic cylinders, hydrocarbon industries, and in Oil and Gas infrastructure. This pipe is cold drawn and hot-rolled. This pipe is generally welded. This pipe is usually welded by bending the flat material, and a weld seam can be found on the above. Seamless Steel Pipe is manufactured using a process that heats and moulds a solid billet into a cylindrical shape and then rolls it until it is stretched and hollowed. Since the hollowed centre is irregularly shaped, a bullet-shaped piercer point is pushed through the middle of the billet as it is being rolled.
