A335 P11 Pipe

Xi 'An QinSteel Trading Co., Ltd – Your Trusted Partner for Premium A335 P11 Pipes

When your project demands A335 P11 Pipe solutions that withstand extreme heat and pressure, you need a partner who combines material science expertise with precision manufacturing. Our chromium-molybdenum alloy steel pipes are engineered for critical applications in power generation, refineries, and petrochemical systems, delivering unmatched performance under temperatures up to 600°C (1112°F).

Why A335 P11 Pipes?

The product is a seamless, high-temperature alloy steel pipe designed for environments where standard carbon steels fail. With a chromium content of 1.00-1.50% and molybdenum (0.44-0.65%), it offers superior oxidation resistance and creep strength, making it ideal for:

• Power plant steam lines
• Oil and gas refinery piping
• High-pressure boiler systems
• Petrochemical processing units
