ASTM A335 high-temperature steel pipe is a high-performance pipe designed for extreme high-temperature environments.
It is made of high-quality high-temperature alloy steel, and its alloy composition is carefully formulated, including key elements such as chromium, molybdenum, and tungsten. The combination of these elements gives the steel pipe excellent high-temperature strength and oxidation resistance, enabling it to operate stably at temperatures up to 550°C or even higher, and effectively resist material softening and oxidation corrosion at high temperatures.
In terms of manufacturing process, advanced seamless or welding technology is used to ensure precise dimensional accuracy and pipe wall uniformity, reduce stress concentration caused by uneven wall thickness, and enhance the pressure-bearing capacity of the pipeline under high temperature and high pressure. Its smooth inner surface facilitates the smooth flow of high-temperature media, reduces fluid resistance and ene…
