Stainless Steel Boiler Tubes

SS 304 Seamless Boiler Tubing and AL294C Vent Pipe manufacturer in India

Stainless Steel Boiler Tubes

Boiler tubes are made to withstand high temperature and high pressure and they are used as energy equipment, they are a combination of different types of steels. Stainless steel boiler tubes are used widely in comparison to Steel Boiler tubes. The basic function of these tubes is to heat the water so that the boiler can produce steam. The circulating water in the stainless steel boiler tube is heated by the hot gases generated outside by the furnace. Stainless steel boiler vent pipe is designed in such a way that the risk of fire outrage in a common household is decreased to a minimum in boiler applications. There are cylinder systems that help in converting the hot environment of the boiler to cool down quickly, this helps to avoid application damage due to overheating unless steel boiler flue pipe is used for ventilation of hot gases produced by the furnace inside a boiling application.

These flue pipes convert heat energy of boilers into a liquid form or other gaseous form to cool down quickly. But compared with traditional stainless steel welded flue pipes, stainless steel piping systems can save a lot of time and cost. AL 29-4C Pipe alloy is super ferritic. In super ferritic alloys, alloys can have clearance at a very low level. Super ferritic steel can be processed without difficulty. They are mainly used for extreme resistance to chloride ion pitting, general oxidizing corrosions and used for extreme corrosions too like crevice corrosion and cracking due to stress corrosion.

Straightness of SS Boiler Tube

  • for 1 meter length the permitted straightness is 3 millimeters.
  • Permitted straightness is 0.0015 multiple of the Tubes length

 

Stainless Steel Fire Tube Boiler Surface Protection

Whereas requesting, it is fundamental to concur upon the strategy and implies of briefly securing the surface of the tubes amid transportation and capacity.

 

SS Seamless Boiler Tubing Tolerances

  • Wall Thickness: ±10%
  • Hardness: Maximum 80 HRB (Rockwell)
  • Chemistry: Min. 2.5% Molybdenum
  • OD Tolerance: +0.005/-0 in.

 

Advantages of Jindal Boiler Tube

  • have greater corrosion resistance
  • improves system safety and reliability
  • available in custom lengths
  • reduced installation costs
  • preventing the possibilities of leaks and other long-term failures
