ASTM A335 / ASME SA335 P22 Alloy Steel Seamless Pipe 2.25Cr-1Mo Steel Pipe
ASTM A335 P22 is a type of alloy steel pipe that is designed for high-temperature and high-pressure applications. It is made from a combination of chromium, molybdenum, and other elements, which gives it excellent corrosion resistance and high-temperature strength. Here are some key features and properties of A335 P22 pipes:
- High-temperature strength: A335 P22 pipes can withstand high temperatures up to 600°C (1112°F) without losing their strength and performance.
- Corrosion resistance: A335 P22 pipes are highly resistant to corrosion, making them ideal for use in harsh environments.
- Ductility: A335 P22 pipes have good ductility, which allows them to be easily formed and welded.
- Versatility: A335 P22 pipes can be used in a variety of applications that require high-temperature and high-pressure resistance, such as power generation plants, oil and gas refineries, chemical processing plants, and aerospace industry.
- Availability: A335 P22 pipes are widely available in different sizes, wall thicknesses, and lengths to suit various applications.
