Product Description

JIS 3461 STB35 Carbon steel pipe for boilers and heat exchangers

JIS G3461 STB 35 used for exchanger heat on 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. used in chemical and petroleum industries. However, it is no application to the steel tubes for heating furnace and steel heat exchanger tubes for low-temperature service. ANSON is an experienced boiler and pressure steel tube supplier which can offer you JIS G3461 steel tubes of all grade and dimension range.

The physical properties of STB35 JIS G3461 include high strength, low weight, durability, ductility and resistance to corrosion. Steel, as we all know, offers great strength though it is light in weight. In fact, the ratio of strength to weight for steel is the lowest than any other building material available to us.
