Stainless Steel Seamless Pipe Description

By  definition, seamless tubes are completely homogenous tubes, the  properties of which give seamless tubing more strength, superior  corrosion resistance, and the ability to withstand higher pressure than  welded tubes. This makes them more suitable in critical applications in  harsh environments, but it comes with a price.

Stainless Steel Seamless Pipe Manufacturing

Knowing  that distinction can also help in determining which tubing is best for a  given application, welded or seamless. The method of manufacturing  welded and seamless tubing is evident in their names alone. Seamless  tubes are as defined – they do not have a welded seam. The tubing is  manufactured through an extrusion process where the tube is drawn from a  solid stainless steel billet and extruded into a hollow form. The  billets are first heated and then formed into oblong circular molds that  are hollowed in a piercing mill. While hot, the molds are drawn through  a mandrel rod and elongated. The mandrel milling process increases the  mold’s length by twenty times to form a seamless tube shape. Tubing is  further shaped through pilfering, a cold rolling process, or cold  drawing.
