Threaded Flange Manufacturer & Supplier in India
Hi-Tech Engineering is a Threaded Flange Manufacturer & Supplier in India, offering high-quality forged threaded flanges for industrial piping systems, oil & gas facilities, petrochemical plants, chemical processing industries, and power generation applications. We supply carbon steel, stainless steel, and alloy steel threaded flanges manufactured according to ASME, DIN, EN, and JIS standards.
Threaded Flanges, also known as Screwed Flanges, are designed with internal threads that allow direct connection to threaded pipes without welding. These flanges are widely used in low-pressure piping systems and applications where welding is not practical or permitted. Available in various sizes, pressure ratings, and material grades, threaded flanges provide easy installation and maintenance.
What is a Threaded Flange?
A Threaded Flange is a type of pipe flange that contains internal threads matching the external threads of a pipe. Unlike welded flange connections, threaded flanges can be installed without welding, making them suitable for applications requiring quick assembly and disassembly.
Threaded Flanges are commonly used in utility piping systems, water lines, compressed air systems, fuel lines, and low-pressure process piping. Their simple installation process and maintenance-friendly design make them a practical choice for many industrial applications.
