Class 2500, Astm A182 F22 Material, RTJ, Asme B16.5 Standard High-Pressure Welding Flange For Power Plants

This high-pressure weld neck flange 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.

Specifications

1. Petrochemical Hydrogenation/Reforming Units: High-temperature and high-pressure reaction pipelines in hydrocracking and hydrorefining units; reactor inlet and outlet, and 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, effectively prevents leakage risks.

2. Thermal Power/Power Plant Boilers and Steam Systems: Superheater and reheater outlet pipelines in power plant boilers; High-temperature and high-pressure steam main pipelines, and turbine inlet pipelines.

F22 (2.25Cr-1Mo) alloy steel possesses excellent high-temperature strength and resistance to steam oxidation, making it a commonly used material in high-temperature and high-pressure steam systems of supercritical/subcritical power plants. Combined with Class 2500 grade and butt-welded construction, it can withstand thermal cycling and pressure fluctuations.

3. Coal Chemical/Ammonia Synthesis Units
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 operating conditions involve hydrogen and sulfur-containing media with high temperatures and pressures, demanding extremely high material resistance, corrosion resistance, and sealing reliability. The high impact toughness of F22 Class 3 and RTJ sealing surfaces are crucial for ensuring safety.

4. High-Pressure Oil and Gas Wellheads and Deep-Sea/Offshore Platforms
Connecting flanges for high-pressure wellhead equipment and Christmas trees
High-pressure oil and gas transmission pipelines on deep-sea/offshore platforms.
Class 2500 is one of the highest pressure ratings in ASME B16.5 standards. 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 scenarios.

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.
