Fertilizer steel pipes are divided into general boiler tubes and high-pressure boiler tubes according to the high temperature performance they bear. Regardless of general boiler tubes or high-pressure boiler tubes, they can be divided into various steel pipes according to their different requirements. Fertilizer special steel pipes are mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel high-pressure seamless pipes for steam boiler pipes with high pressure and above. These boiler pipes work under high temperature and high pressure. Oxidation and corrosion will also occur under the action of high-temperature flue gas and water vapor. Therefore, the steel pipe is required to have high enduring strength, high oxidation resistance, and good organizational stability. The high-pressure boiler pipe must ensure chemical composition and mechanical properties. In addition, it is necessary to do a hydraulic test one by one, and do a flaring and flattening test. The fertilizer special steel pipe is delivered in a heat-treated state.
