ASME / ASTM A335 Alloy Steel P12 Pipes Manufacturer
ASTM A335 Alloy Steel P12 Pipes is a high-strength and corrosion-resistant pipe material. It is made from a combination of chromium, molybdenum, manganese, phosphorus, silicon, and carbon in different proportions. It is an excellent choice for applications requiring corrosion resistance and good tensile strength at high temperatures. ASTM A335 Alloy Steel Pipes are widely used in the oil and gas, power generation, and petrochemical industries.
The ASTM A335 Alloy Steel P12 Pipes are used in the energy industry for high-temperature and very low-temperature service (cryogenic) or applications with very high pressures. They are also commonly used in the petrochemical and chemical industries. The alloy pipes are available in various grades, execution, tolerances, and lengths.

ASTM A335 Alloy Steel P12 Pipes are tubular with higher percentages of alloying elements (Nickel, Molybdenum, and Chromium) than standard carbon steel pipes. They offer excellent corrosion resistance at high temperatures, prevent steel oxidation at elevated temperatures, and increase tensile strength and hardness. They are resistant to abrasion and provide good mechanical properties also they have excellent welding properties and can be used in many applications. There are several products available like ASTM A213 T11 Alloy Steel Tubes etc. These pipes are available in different shapes, such as round, square, rectangular, and hydraulic. They are used in oil and gas, petrochemical, and other high-temperature and high-pressure applications.

A335 P12 Pipes are used in various applications such as power generation and petrochemical plants. They are known for their excellent tensile strength and good resistance to high-temperature corrosion and oxidation. They are also suited for oil field services where fluids and gases are transported at extremely high temperatures and pressures. They are widely used for boilers and heat exchangers in these industries. We offer various kinds of products like Alloy Steel P9 Tubes etc. They are also used in other applications, such as sugar manufacturing factories. They are oxidation resistant and can be easily welded.
ASTM A335 Alloy Steel P12 Pipes have remarkable resistance to corrosion and good tensile strength at high-temperature service also they are often used in power generation and downstream oil and gas. They can resist pitting and crevice corrosion cracking, even at hoist temperatures.
What is ASTM A335 P12 Pipe?
ASTM A335 P12 is a seamless ferritic alloy steel pipe specification for high-temperature service. It is commonly used in the power generation industry for steam piping, turbine components, and other high-temperature services. The pipe combines chromium, molybdenum, and other alloying elements that provide high strength, corrosion resistance & excellent heat resistance at elevated temperatures. ASTM A335 P12 pipe is available in different sizes & thicknesses to meet specific application requirements.
What is the difference between A335 P11 and A335 P12 Pipe?
A335 P11 and A335 P12 are chrome-moly alloy steel pipes used in high-temperature and pressure applications. The main difference between them is their composition and mechanical properties. A335 P11 has a minimum tensile strength of 415 MPa and a minimum yield strength of 205 MPa, while A335 P12 has a minimum tensile strength of 415 MPa and a minimum yield strength of 220 MPa. Additionally, A335 P12 has higher levels of chromium and molybdenum, which provide better resistance to corrosion & higher temperature strength than A335 P11.
