TP321 / 321H Stainless Steel U Bend Pipe , 321 Stainless Steel Tubing Heat Exchanger SA213

 

Grade 321 is a common austenitic 18/8 stainless steel alloy, with the addition of titanium, making it a good choice in high temperature environments of up to 900° C. 321 stainless steel has good welding and forming capabilities and is widely used in operating temperature environments in excess of 500° C.

 

Stainless steel 321H, commonly referred as UNS S32109, is the higher carbon version of the 321 grade, to provide higher temperature strength.321/321H Pipes,Tubes and 321H pipe fittings are mainly used in manufacturing heat exchangers, pressure vessels, pharmaceutical and chemical processing equipments.

 

Standard Technical Range

  • OD 9.5mm - 38.1mm
  • WT up to 6.35mm
  • Bending radii 1.25 x OD up to 1700mm
  • Bends can be supplied in accordance with TEMA R / ASTM SA/A556
  • Leg length up to 15000mm
  • Heat treatment where required by electric furnance or direct resistance
  • Hydrotesting up to 10,000 psi

Additional Testing

  • Dye penetrant of 'U' bend area
  • PMI testing
  • Heat Treatment

Heat Treatment

We are equipped to carry out heat treatment of bends plus a minimum 150mm of leg.
 

Heat Treatment Equipment

  • Heat treatment equipment is computer controlled with the added facility of data recording.
  • An argon protective atmopshere is used inside stainless and special alloy tubes during heat treatment.
  • We can provide all types of annealing; solution annealing and stress relieving.
