Industry Standard Class 150 Flanges

Industry Standard Class 150 flanges are designed to balance sealing reliability and versatility. They are widely applicable to medium- and low-pressure piping systems in various industries, including petrochemicals, municipal engineering, food and pharmaceuticals, and energy and power. They are core components for connecting pipes, valves, pumps, and containers.

The core process of the Industry Standard Class 150 Flanges production method is as follows: first, raw materials such as carbon steel (such as A105) and stainless steel (such as 304/316L) are cut and cleaned. Then, the blanks are formed by forging/casting according to the flange type (flat weld/butt weld/threaded). Flat weld flanges are mostly forged and stamped with flanging, butt weld flanges require forging an integrated long neck, and threaded flanges are tapped after forming). Then, they are processed by CNC turning and drilling to ensure dimensional accuracy. Then, heat treatments such as normalizing (carbon steel) and solid solution (stainless steel) are performed according to the material to optimize performance. Finally, surface treatments such as galvanizing, painting, or pickling and passivation are performed. Finally, dimensional inspection, non-destructive testing, and pressure testing are carried out to ensure compliance.
