Steel Boiler Tube

The steel boiler tube supplied by N-STEEL comes with a wide OD range from 19mm to 711mm and a wide wall thickness range from1.65mm to 50mm. According to actual applications, this seamless steel tube is available in two types, namely ordinary boiler tube and high-pressure boiler tube.

The usage temperature of ordinary steel boiler tube is less than 350℃. So, thisboiler steel tube is mainly used for water wall tube, boiling water tube, superheat steam pipe, superheat steam pipe for locomotive boiler, large and small smoke tube and arch tube, etc.

The high temperature boiler tube we supply features excellent endurance strength, great resistance to oxidation and superior structure stability. Thus, it is suitable for a high temperature and high pressure usage environment where the metal pipe under the action of high temperature smoke and water vapor is easy to be oxidized and corroded.

Specifically, our high temperature steel boiler tube is mainly used for superheater tube, reheater tube, gas-guide tube, main steam pipe, etc. in high pressure or super high pressure boilers.
