Product Overview
This ASTM A182 F22 Alloy Steel Flanges has a pressure rating of 2500 psi and is made of a special material, F22/12Cr2Mo. It conforms to ASTM A182 F22 standards and offers excellent corrosion resistance and weldability. Manufacturing standards comply with ASTM B16.5, and it is commonly used in the petrochemical industry.
Key Details
Mill Test Report (MTR) Available
High-temperature and high-pressure reaction pipelines in hydrocracking and hydrorefining units-including reactor inlet and outlet piping, plus high-temperature oil and gas pipelines in reforming units. F22 alloy steel's resistance to hydrogen corrosion and high-temperature creep, combined with RTJ metal ring seals on high pressure flanges, effectively prevents leakage risks.
Superheater and reheater outlet pipelines in power plant boilers, high-temperature high-pressure steam main pipelines, and turbine inlet piping. F22 (2.25Cr-1Mo) alloy steel provides excellent high-temperature strength and resistance to steam oxidation-making it a standard material in supercritical and subcritical power plant systems. Combined with Class 2500 high pressure flanges and butt-welded construction, it withstands thermal cycling and pressure fluctuations.
High-temperature coal gasification and syngas transmission pipelines in coal chemical plants, high-pressure synthesis towers and ammonia separation systems in ammonia synthesis units. These conditions involve hydrogen and sulfur-containing media at high temperatures and pressures, requiring exceptional material strength, corrosion resistance, and sealing reliability. The high impact toughness of F22 Class 3 with RTJ sealing surfaces on high pressure flanges is critical for safe operation.
Connecting flanges for high-pressure wellhead equipment and Christmas trees, high-pressure oil and gas transmission pipelines on deep-sea and offshore platforms. Class 2500 is one of the highest pressure ratings in ASME B16.5 standards for high pressure flanges. Combined with RTJ sealing surfaces, it achieves zero-leakage metal-to-metal seals under high pressure, vibration, and harsh environments-making it the preferred choice for high-risk, high-pressure oil and gas applications.
We understand that reliability is paramount for wholesalers. Therefore, we solemnly promise the following for every order:
First, Quality Guarantee: If any pipe does not meet ASME B16.5 standards-whether it's dimensional deviations, surface defects, or corrosion resistance issues-we will replace it free of charge.
Second, Fast Delivery: We ship within 48 hours. For large orders or custom specifications, we complete them within 7-10 business days-faster than most of our slow competitors.
Third, Easy Documentation: We send you all the necessary documents in advance-ASTM A182 certification, EU Certificate of Conformity (CoC), Material Safety Data Sheet (MSDS), and Material Test Report (MTR). You won't need to chase us for forms when dealing with customs or customer audits-you'll have all the necessary documents from day one.
Fourth, 24/7 Support: Your dedicated account manager is fluent in English and has extensive knowledge of ASTM A182 standards. Need assistance with specifications, order updates, or custom cutting services? They'll respond within an hour.
