Product Description

 Applications of JIS G3461 carbon steel tubes is a kind of pipe used for transferring heat inside and outside pipe. It can widely used as smoke tube, superheater tubes, boiler water tubes, air preheating tubes, accessories. JIS G3461 STB 340 Tubes required low temperature annealing or normalizing may be performed.

JIS G3461 STB 410 Tubes required low temperature annealing or normalizing may be performed. It can also be used in petroleum and chemical industries but it can't be used for low temperature services. We supply different grades of carbon steel pipes, regarding JIS G3461 STB JIS G3461 340, JIS G3461 STB 510, JIS G3461 STB 410, etc.
