Manufacturing Standards: ASME/ANSI B16.5, DIN, EN1092-1, JIS B2220, GOST.
Flange Types: Weld neck (WN), Slip-on (SO), Socket weld (SW), Blind, Threaded.
Main Applications
Petrochemical and Natural Gas: Suitable for the harsh environments of oil refineries, offshore drilling platforms, and long-distance pipelines with high pressure and strong corrosion.
Engineering and Municipal Engineering: Widely used in water supply and drainage networks, fire protection systems, and urban central heating pipelines in large commercial buildings.
Water Treatment & Power: Meets the stringent requirements of acid and alkali resistant pipelines in chemical plants, wastewater treatment facilities, and high-temperature, high-pressure steam systems in power plants.
Key Product Advantages
Precision CNC Machining: Utilizing fully automated CNC machine tools, flanges exhibit uniform thickness and extremely high surface finish on sealing surfaces (RF/FF/RTJ), ensuring zero leakage at flange connections.
Superior Corrosion and Pressure Resistance: 304/316 stainless steel provides top-tier rust resistance, a thick galvanized layer effectively resists external environmental corrosion, and carbon steel construction ensures structural stability under high-pressure conditions.
Efficient and Seamless Installation: Precise hole diameter and center distance dimensions perfectly match various standard pipes and fittings, significantly reducing welding and assembly difficulties on-site.
Quality & International Certification: Each batch of products undergoes rigorous ultrasonic testing and hydrostatic testing. The products have passed ISO 9001 quality management system certification, CE EU safety certification and relevant industry standard certifications. The products are equipped with EN 10204 3.1 material testing report (MTC) as standard, ensuring free circulation in the global market and meeting the acceptance standards of various multinational engineering projects.
