Product Description

Introduction
JIS G3461 STB 410 carbon tubes used for exchanging heat on the inside and outside of the tube,such as water tubes,smoke tubes,superheater tubes,air preheater tubes,etc.of the boiler,and heat exchanger tubes,condenser tubes,catalyzer tubes,etc.

JIS G3461 specifies carbon steel pipes used to transfer heat inside and outside the pipe, such as boiler water pipes, smoke pipes, superheaters, air preheaters, etc. This Standard specifies tubes used for exchangers, condenser tubes, catalyst tubes, etc. However, this does not apply to steel pipes for heating furnaces and steel pipes for low-temperature heat exchangers. This standard normally applies to pipes with an outside diameter between 15,9 mm and 139,8 mm.
 

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.
