Product Details

JIS G3462  is a JIS standard refers to alloy steel boiler tubes and heat exchanger tubes. This steel tubes is used in carbon steel pipes for tube heat-exchange inside and outside, such as boiler water steel pipe, superheater tube, condenser tube and more.
However, it is not applicable to the steel tubes for heating furnace and steel heat exchanger tubes for low temperature service.
The size range of  JIS G3462 boiler tubes(mm):

  • Outer Dimensions: 19.05mm-168.3mm

  • Wall Thickness:2.0mm-14 mm

  • Length: max 19000mm

Application of JIS G346s seamless tubes:

  • used for exchanging heat on the inside and outside of the tube, such as water tubes, smoke tubes, superherater tubes, air preheater tubes, etc. of boilers, and heat exchanger industries.

  • it is not applicable to the steel tubes for heating furnace and those for heat exchangers for low temperature service.
