Screwed Flange (Threaded Flange)
A Screwed Flange, also known as a Threaded Flange, is a type of pipe flange designed with internal threads that allow it to be connected to threaded pipes without welding. Its easy installation and removal make it an ideal choice for low-pressure and non-critical piping systems, especially where welding is difficult, hazardous, or not permitted.
At Royal Steel India, we manufacture and supply premium-quality Screwed Flanges in a wide range of sizes, pressure classes, materials, and international standards. Our flanges are precision-machined to ensure accurate threading, excellent durability, and reliable performance in various industrial applications.
A Screwed Flange is a flange with internal threads that match the external threads of a pipe. It can be easily screwed onto the pipe, creating a secure connection without the need for welding. This feature makes installation faster, reduces maintenance time, and allows the piping system to be dismantled whenever required.
Screwed Flanges are widely used in systems carrying air, water, gas, oil, and other low-pressure fluids where frequent maintenance or easy installation is important.
