In the past ten years, with the development of ultra-supercritical units with large capacity and high parameters, higher quality requirements have been put forward for the ASME SA213 T22 boiler pipe of carbon steel and low alloy steel series, not only high temperature strength, but also sufficient high temperature strength. Durable strength and plasticity, good oxidation resistance, impact property, uniform performance of ASME SA213 T22 boiler pipe, strict requirements of dimension tolerance and external surface quality, and good weldability and hot working performance about ASME SA213 T22 boiler pipe.
Heat treatment is the key procedure in the production process of ASME SA213 T22 boiler pipe. Heat treatment has an important effect on the internal quality and surface quality of pipe, especially for the production of ASME SA213 T22 boiler pipe. It has a great influence on the durable performance of high-pressure boiler tubes for utility boilers. Stable metallographic structure and good internal and external surface quality represent the manufacturing level of ASME SA213 T22 boiler pipe enterprises.
After the determination of the chemical composition of the ASME SA213 T22 boiler pipe, what endows the steel pipe with excellent mechanical properties and internal structure is the wide range of technological parameters given by the heat treatment process and the ASME standard, and the production enterprises need field tests. Find out the suitable heat treatment workmanship. ASME SA213 T22 boiler pipe normal heat treatment technology: 920℃-940℃ normalizing, heat preservation more than 20 minutes, 720℃-740℃ tempering, 2 h heat preservation
