This tube is used for high pressure boilers. The seamless high pressure boiler tube is produced with the method of Hot Rolling(Extrusion), Cold Drawn or Cold Rolled, according to the Chinese standard GB 5310-1995.

GB5310-1995, one kind of seamless steel tubes, mainly used to manufacture high pressure steam boiler and above pipelines with high-quality carbon steel, alloy steel and heat-resistant seamless stainless steel tubes.

Feature of seamless high pressure boiler tube: Persistent high strength, high oxidation resistance, good organizational stability

Application of the seamless boiler tube: For high pressure boilers.

Produce method for high pressure boiler tube: Hot rolling(extrusion), cold drawn, cold rolled.

The seamless carbon high pressure boiler tubes material:

10#/20#/Q345/20G/15MnG/20MnG/15MoG/20MoG/16Mn/15CrMo/15CrMoG/12Cr1MoV/12Cr1MoVG/Cr5Mo/10CrMo910 and so on.

The boiler tubes often work in high temperature and high pressure, pipe in high temperature smoke and steam will meet oxidation and corrosion, thus it requires a durable steel Persistent high strength, high oxidation resistance, good organizational stability.

Seamless high-pressure boiler pipe: for the manufacture of a variety of high pressure boiler superheated steam pipes, boiling water pipe, water wall tubes and superheated steam locomotive boiler tubes, opium pipe, small pipe and brick arch tubes. (Dial) seamless steel pipe with high quality carbon structural steel hot or cold. 20# steel is mainly used, in addition to chemical composition and mechanical properties will do hydrostatic testing, curling, flaring, flattening and other tests. State of delivery hot rolled, cold-rolled (dial) to heat treatment delivery.
