Flanges

As a leading manufacturer of high-performance industrial flanges, we provide essential connection solutions for piping systems across the most demanding global sectors. Our production focuses on forged and plate-cut flanges—including Weld Neck, Slip-On, Blind, and Socket Weld types—engineered to meet stringent international standards like ASME B16.5, DIN, and EN 1092-1. By utilizing precision forging and advanced CNC machining, we ensure that every flange offers superior structural integrity, leak-proof sealing, and the fatigue resistance required for high-pressure service.

Our material expertise allows us to support a diverse range of operational environments. We manufacture Carbon Steel (ASTM A105, A350 LF2) flanges for general industrial and low-temperature strength, and Alloy Steel (F5, F11, F22) for high-temperature power plant and refinery applications. For projects requiring hygiene and rust prevention, our Stainless Steel (304/L, 316/L) range is the industry standard in food, pharmaceutical, and chemical processing.

For the most extreme conditions, we specialize in Nickel Alloy flanges (Inconel, Monel, Hastelloy). These high-grade components are purpose-built for environments where standard materials fail, such as offshore oil platforms, aerospace components, and aggressive chemical reactors. Whether you need a standard 150# class flange or a custom-engineered 2500# high-pressure solution, our manufacturing process is optimized to deliver durability and safety for your critical infrastructure.
