Tubos India is one of the large manufacturers for high quality Alloy Steel JIS G3462 Tubes. Applications of JIS G3462 Alloy Steel Tube alloy steel pipe is mostly used for exchanging heat on within and in the surrounding of the underground. It can use as smoke tube, water tube, superheated tubes, air preheater tube, etc. Higher temperature resistance or capacity corrosion, end up being widely used by boiler, petroleum, chemical engineering, heat exchanger and other power areas.
The Outer dimension is from 19.05 mm to 168.3 mm & wall thickness ranges from 3.0 mm to 14 mm. JIS G3462 alloy steel tube is not applicable for heating heat exchangers and furnaces for low temperature service. We supply various grades of alloy steel pipes such as STBA13, STBA12, STBA20, STBA22, STBA23, STBA25, STBA24, STBA26, etc.
