ASTM A335 P22 PIPE & TUBE

INFORMATION PRODUCT

ASTM A335 P22 PIPE & TUBE

P22 pipes typically have a nominal pipe size ranging from ½ inch to several inches in diameter, with wall thicknesses conforming to specific schedules. They are designed to handle high pressures and temperatures, improving their performance in steam lines and other demanding environments.

P22 pipe, made from a specific type of alloy steel often referred to as ASTM A335 P22, is designed for high-temperature service and is commonly used in various industrial applications. This pipe is known for its excellent strength and creep resistance at elevated temperatures, making it ideal for power generation and petrochemical plants.

P22 applications, P22 is widely used in boiler systems, heat exchangers, and superheaters, where reliability and integrity over time are critical. It is often coated or treated to resist corrosion, enhancing its lifespan in harsh environments.
