ASTM/DIN/JIS/GOST Seamless boiler steel pipes and tubes

Boiler pipes often in high temperature and high pressure work, pipe smoke and water at high temperature steam oxidation and corrosion effects will occur, thus requiring durable steel with high strength, high oxidation resistance, and good organizational stability, high pressure boiler tube in addition to chemical composition and mechanical properties, hydrostatic testing done by the root, to be flaring, flattening test. Steel to heat treatment delivery. In addition, the finished steel microstructure, grain size, there are certain requirements decarburization.

Specification of Seamless Boiler Steel Pipe & Tube :

seamless boiler tube is widely used in boiler industry, petroleum, chemical industry, chemical fiber, metallurgy, medicine, machinery, paper, heat preservation, refrigeration, mechanical equipment, food, electricity, water, construction, aviation, aerospace, marine, shipbuilding, environmental protection and boiler heat exchangers.
