Stainless Steel Welded Tube for Heat Treatment

Stainless Steel Welded Tube for Heat Treatment
ASTM A249/A269/EN10217-7
Stainless steel tube for heat treatment are designed to withstand high temperatures without corrosion or degradation.  

Stainless Steel Process Tubes are mainly used in bolier, heat exchanger,  super heater and condenser which  are widely used for the industries like petroleum, chemical, paper, fertilizer and nuclear. 

These tubes are often made from corrosion-resistant stainless steel alloys like 304, 316, or 321 due to their ability to withstand heat and resist oxidation at elevated temperatures.

Product Advantages

  • Complete testing equipments to improve the quality.
  •  The thickness and diameter tolerance of the tubes are produce strictly according to international standards: ASTM A249/A269/EN10217-7.
  • The production processes (Annealing and inside bead removing) are strictly controlled, the temperature of annealing is contarolled in 1050℃ to 1080℃ to ensure the physical and mechanical properties of tubes.

Manufacturer Processes 



The Bright Annealing process in Vinmay  is performed in a controlled atmosphere containing inert hydrogen gas at 1040℃. Annealing is a typically used to reduce hardness , increase ductility and eliminate internal stresses.While the controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Picking is not needed after bright annealing since the oxidation is minimal. Since there is no pickling , the surface of stainless steel sanitary tube is much smoother which results in better resistance to pitting corrosion.

After the process, bright annealed finish has a bright, reflective appearance, but may have some cloudiness slightly different from MF (Mill Finish)
