The seamless steel pipe is made of a solid round billet which is first heated and then extruded - pushed or pulled through the mould to give a hollow tube. This process smoothes the surface of the seamless steel pipe without any visible seams. This product is more expensive than welded tubes, but is also considered to be more reliable and allows for higher strength and integrity.
