DUPLEX STAINLESS STEEL TUBING : PRODUCT

Duplex stainless steel tubing has a chemical composition of approximately equal parts of austenite and ferrite which is why it has twice the design strength of normal austenitic and ferritic stainless steel tubing. Duplex stainless steel tubings have a wide range of corrosion resistance levels. They also have high resistance to stress corrosion cracking that they might have received from its ferritic side. Duplex stainless steels are still very much in their developing stages and there are constantly different brands being promoted, this should continue till an accomplished and proven grade emerges. Duplex stainless steel tubes are used by a number of companies across the globe because they are very cost effective.

We stock and outsource tubing from 1/16″ to 2″.

DUPLEX STAINLESS STEEL TUBING : TYPES

There are four types of duplex stainless steel tubing that we manufacture at Instinox.

  • Hot finished seamless duplex stainless steel tubing (HFS): HFS tubing is manufactured with respect to outer diameter and wall thickness dimensions. It is more cost effective than cold drawn seamless duplex stainless steel tubing. It is used in tubing that requires thicker walls and higher strength.
  • Cold drawn seamless duplex stainless steel tubing (CDS): CDS tubing offers better machinability, increased strength and tolerances compared to HFS tubing. CDS increases the tubes physical properties.
  • Electric-resistance welded (ERW): ERW process involves spot and seam welding. In ERW the sides are trimmed to control the width and the condition the edges for welding. It is then passed through a number of contoured rollers which cold form the duplex stainless steel into a tube.
  • Drawn over mandrel (DOM): DOM is not exactly a type of stainless steel tube it is more of the process in which the tube is finished. The manufacturing process is almost the same as ERW except that in the end stages the tube is cold drawn over a mandrel.
