ASME SA335 P9 seamless pipe is mainly composed of elements such as chromium and molybdenum. It is a low-alloy high-strength steel pipe. It is widely used in high-temperature, high-pressure, flammable and explosive pipelines in petroleum refining plants, especially direct heating pipes in heating furnaces, and the medium temperature can reach 550~600℃.
The production process of SA335 P9 alloy steel seamless pipe provided by GNEE strictly follows the ASTM A335/A335M standard and adopts advanced seamless ferrite alloy steel production technology.
The production methods include hot rolling, cold drawing and hot expansion, and the delivery state is heat treatment.
