High Threaded Flanges, also known as Screwed Flanges, are designed with internal threads that allow them to be directly connected to externally threaded pipes without the need for welding.
These flanges are particularly suitable for high-pressure, small-diameter piping systems where welding is not preferred or feasible, such as in hazardous environments or where easy installation and dismantling are required.
