The ASTM A335 P12 and P22 pipes from Huanan Special Steel Co. are seamless alloy steel pipes manufactured via hot rolling or cold drawing. The P12 grade contains a chromium-molybdenum composition suited for high-temperature service up to 550°C, while P22, with 2.25% chromium and 1% molybdenum, offers superior creep resistance for superheater and reheater applications in power plants and refineries. Both grades comply with ASTM A335, a standard for ferritic alloy steel pipes intended for high-temperature service.
These pipes are produced in size ranges from 12.7 mm outer diameter with 1.2 mm wall thickness to 1030 mm outer diameter with 50 mm wall thickness. Delivery conditions include normalized, normalized and tempered, or quenched and tempered states to meet specific mechanical property requirements. The alloy steel composition ensures high tensile strength and resistance to thermal degradation, making them ideal for critical piping systems in petrochemical and power generation facilities.
Primary buyers include EPC contractors, power plant operators, and petrochemical facility managers sourcing reliable piping for high-pressure and high-temperature environments. Huanan Special Steel Co. supplies these pipes in fixed lengths, often used in boiler systems and heat exchangers. Buyers should confirm packaging, lead times, and incoterms directly with the supplier, as these details are tailored to bulk export trade requirements.
