Threaded Flange (Ministry of Chemical Industry Standard)

The Threaded Flange, manufactured in accordance with Ministry of Chemical Industry (HG) standards, is designed for piping systems where welding is not preferred or feasible. It features internal threads that allow it to be directly screwed onto pipes, providing a convenient and efficient installation solution.

This type of flange is especially suitable for low-pressure and non-critical applications, commonly used in chemical processing, water treatment, and utility systems.
