Stainless Steel Seamless Pipe

Short Description:

Stainless steel seamless pipe represents one of the most versatile and reliable material forms in modern engineering, distinguished by its manufacture without longitudinal weld seams and its inherent resistance to corrosion across a broad spectrum of environments.

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.
