T11 alloy steel pipe: ASTM A213 T11 is a low-alloy chromium-molybdenum steel pipe in which the main alloying elements are chromium and molybdenum. T11 steel pipe is usually used in medium and high temperature boiler systems, and its high temperature resistance and oxidation resistance are excellent.
T22 alloy steel pipe: ASTM A213 T22 is a low-alloy chromium-molybdenum steel pipe. Its main alloying elements also include chromium and molybdenum, but compared with T11, T22 contains more molybdenum. T22 steel pipe is commonly used in higher temperature boiler and heat exchanger applications, offering superior high temperature strength and corrosion resistance.
These alloy steel pipes have good oxidation resistance and can prevent oxidation and corrosion of pipes or equipment at high temperatures, which is crucial for long-term operation and high-temperature applications. They have good corrosion resistance to acidic and alkaline media, making them capable of meeting the challenges of various corrosive media in the chemical and petroleum industries. At the same time, the high-temperature strength of these two alloy steel pipes also brings them a wide range of applications, such as boilers and heat exchangers that need to withstand high-temperature and high-pressure working environments.
T11 and T22 alloy steel pipes are widely used in multiple industries, including energy, chemicals, aviation, nuclear energy and automobile manufacturing.
