Description

Product Description

JIS G 3462 tubes are seamless tubes of alloy steel for boilers and heat exchangers, which can be formed by bending, crimping and similar processes, and are also suitable for welding. Pipe material grades (chemical composition) are divided into eight STBA12, STBA13, STBA20, etc., and are manufactured by hot forming or cold drawing process.

Product Size

Outer diameter: 15.9～139.8mm
Wall thickness: 1.2～12.50mm
End: Flat end, beveling optional
Length: 3 to 12 meters or SRL, DRL, double-footed and fixed-footed

Product Packaging

Clear/black paint on exterior surfaces, steel strapping.
