Product Description

JIS G3462 STBA23 Alloy steel boiler and heat exchanger tubes

Higher temperature resistance or capacity corrosion, end up being widely used by petroleum, chemical engineering, boiler, heat exchanger and other power areas.

JIS G3462 STBA23 specifies the alloy boiler steel tubes used for exchanging heat on the inside and outside of the tube, with 8 steel grades from STBA12-STBA26, it has the similar application as JIS G3461, steel tube of this specification could be supplied as U tube. However, it is not applicable to the steel tubes for heating furnaces and those for heat exchangers of low-temperature service. For final product, heat treatment of the bent portion is not usually performed. However, if there is a request from the orderer, agreement on heat treatment. Joyruns is an experienced boiler and pressure steel tube supplier which can offer you JIS G3462 steel tubes of all grade and dimension range.
