The mandrel milling process increases the molds length by twenty times to form a seamless tube shape. While hot, the molds are drawn through a mandrel rod and elongated. The billets are first heated and then formed into oblong circular molds that are hollowed in a piercing mill. 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. Seamless tubes are as defined – they do not have a welded seam. The method of manufacturing welded and seamless tubing is evident in their names alone. Knowing that distinction can also help in determining which tubing is best for a given application, welded or seamless.

In terms of functionality, tubing is generally used in structural and aesthetic applications whereas piping is used for transporting fluids, liquids, and gases. A pipe, on the other hand, is measure by its inside diameter (ID). Tubes are measured by the outside diameter (OD) and wall thickness. Though both the words tube and pipe are often used interchangeably, largely because both are hollow shaped, there are important distinctions between the two when determining welded vs. In choosing between the two keep in mind that first the tubing must be compliant with your project specifications and that secondly, it must meet the conditions for which the tubing will ultimately be used. seamless tubing primarily depends on the application requirements of the product. The two common types of tubing are seamless and welded. Stainless steel tubing is one of the most versatile metal alloy materials used in manufacturing and fabrication.
