Boiler Steel Pipe
The boiler steel pipe often works under high temperature and high pressure. It may be oxidized and corroded in the environment of high temperature flue gas and water vapor. Therefore, the product needs to possess high endurance strength, strong antioxidant property and good organizational stability.Standard and Steel Grade

We often produce the boiler steel pipe by adopting the high-quality carbon structural steel with the grade of 20G, 20MnG and 25MnG as well as the alloy structural steel with the grade of 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. On the basis of guaranteeing the chemical composition and mechanical properties, each piece of the product must pass the hydrostatic test, flaring and flattening test. The boiler steel tube is delivered in the heat treatment state. Additionally, there are certain requirements to the finished steel tube in the respects of microscopic structure, grain size and decarburized layer.
The seamless steel pipe for boiler is compliant with the standard of GB5310-1995. By exploiting the materials of premium carbon steel, alloy steel and heat-resistant stainless steel, it is especially good for making the heating surface of the water tube boiler of high and higher pressure.
