Welded Vs Seamless Stainless Steel Tubing

There are two types of stainless steel tubing: welded and seamless meaning.  The first is a metal tube and the second is a non-metal tube.  There are advantages and disadvantages to both types of tubing. Welded steel tubing is made of metal.

The difference between tubing and piping

Tube and pipe are often used interchangeably, largely due to their hollow shapes Tubing is often used for structural and aesthetic purposes, while piping is used to transport fluids, liquids, and gases.

Manufacturing of seamless tubing

A seamless tube does not have a welded seam.  A solid stainless steel billet is extruded into a hollow tube through an extrusion process To form a seamless tube, the mandrel milling process lengthens the mold by twenty times.  After cold rolling or cold drawing, tubing is further shaped.

Manufacturing of welded tubing

A welded stainless steel tube is formed by rolling strips or sheets of stainless steel into a tube shape, then welding the seam longitudinally.  Cold forming or hot forming can be used to form welded tubing.

Seamless Tubing

Seamless stainless steel tubing is used to manufacture a variety of products. The advantages – More powerful – Exceptional corrosion resistance – Resistance to the pressure is higher The applications – Control lines for oil and gas – Injection lines for chemicals – Safety valves below sea level – Steam and heat trace bundles in chemical processing plants – Transfer of fluids and gases

Welded Tubing

Seamless stainless steel tubing is used to manufacture a variety of products. The advantages – A cost-effective solution – Long lengths are readily available – Lead times are fast The applications – Applications in architecture – Needles for hypodermic injections – Industry of automobiles – Industry of food and beverages – Industry of the seas – Industry of pharmaceuticals

Costs of Welded vs Seamless

Strength and durability are also factors that affect the cost of seamless and welded tubing.  Due to welded tubing's simpler manufacturing process, larger diameter tubing with thinner walls can be produced for a lower price.
