Introduction
ASME SA335 Grade P22 alloy steel pipes are engineered for high-temperature, high-pressure service in critical industries such as power generation, petrochemicals, and oil refineries. These pipes are part of the Chrome-Moly family, renowned for their strength, thermal stability, and corrosion resistance.
Mcneil Instrument stands out as a trusted manufacturer, supplier, and exporter of ASME SA335 P22 alloy steel pipes in India, known for delivering precision-engineered solutions that meet global standards and complex industry demands.
Understanding ASME SA335 Grade P22 Alloy Steel Pipes
ASME SA335 P22 pipes are seamless ferritic alloy steel pipes used for high-temperature applications. They are composed mainly of Chromium (1.90–2.60%) and Molybdenum (0.87–1.13%), which provide:
- High-Temperature Strength: Ideal for steam pipelines, boilers, and heat exchangers.
- Oxidation & Corrosion Resistance: Suitable for chemical plants and high-moisture environments.
- Enhanced Toughness & Ductility: Performs well under pressure and fluctuating temperatures.
- Creep Resistance: Resists deformation under prolonged exposure to stress and heat.
