JIS G3461 Seamless Boiler Tube

Product Detail

Download :JIS G3461 carbon steel boiler and heat exchanger tube




JIS G3461 Carbon Steel Tubes is used for exchanging heat on the inside and outside of the tube, such as water tubes, smoke tubes, superheater tubes and air preheater tubes of the boiler, and heat exchanger tubes,condenser tubes and catalyser tubes used in chemical and petroleum industries. It is not applicable to the steel tubes for heating furnace and steel heat exchanger tubes for low temperature service.
