steel boiler pipe JIS G3461

JIS G3461 Standard specifies the carbon steel tubes, hereinafter refered to as the tubes, used for exchanger heat on the inside and outside of the tube, such as water tubes, smoke tubes, superheater tubes, air preheater tubes, etc.

JIS G3461 is the usages of the boiler, and heat exchanger tubes, condenser tubes, catalyst tubes, etc. used in chemical and petroleum industries. However, it is not applicable to the steel tubes for heating furnace and steel heat exchanger tubes for low temperature service.

The JIS G3461 boiler tube Size (mm):

  • Outer Dimensions: 19.05mm – 168.3mm
  • Wall Thickness:2.0mm – 14 mm
  • Length: max 19000mm
  • Painting: as requested.
