Super duplex stainless steel pipes are designed to have superior mechanical properties, including:

  • Strength;
  • Ductility;
  • Elasticity;
  • Hardness (temperature) and toughness (temperature).

The yield strength of super duplex stainless steel can be anywhere from 3000-3500 MPa. The tensile strength is around 8000 MPa while the elongation at break is less than 20%. It has excellent impact resistance and resistance to corrosion in acid environments such as sulfuric acid or nitric acid, which makes it ideal for applications where corrosive materials must be transported through a pipeline system with minimal risk of damage to the product being transported within its walls.

Pipes Weight Tolerance

  • The pipes’ weight tolerance depends on the nominal pipe size, as listed below:
  • Pipe of NPS 4 (DN100, 114.3mm) and smaller may be weighed in convenient lots; pipe in sizes larger than NPS 4 shall be weighed separately.
  • Pipes NPS 12 (DN300, 323.8mm) and under, weight tolerance is: -3.5% / +10%.
  • Pipes over NPS 12 (DN300, 323.8mm),weight tolerance is: -5% / +10%.

Pipes Quantity Tolerance

  • Should be within -10% to +10% tolerance, as a rule of thumb (-3/+3% should be acceptable).

Pipes Length Tolerance

  • Seamless and Welded (no filler metal added): if cut lengths are ordered, no length of pipe shall be under the length specified and not more than 1/4 in. (6.35 mm) over that specified.
  • Forged and Bored, Cast, and Cast Cold-Wrought: if definite cut lengths are ordered, no length of pipe shall be under the length specified and not more than 1/8 in. (3.2 mm) over that specified.
  • For pipe ordered to random lengths, the lengths and variations shall be agreed upon between the manufacturer and the buyer.
