Threaded Blind Flanges

Threaded Blind Flanges are designed to close the end of piping systems using threaded connections, eliminating the need for welding while providing secure sealing for low to medium pressure applications.

Product Overview

Threaded Flanges

Shatrunjay Special Alloy is acknowledged as a manufacturer, exporter, and supplier of Threaded Flanges and Stainless Steel Flanges (Grades 304, 304L, 316, 316L) available in a wide variety of grades, materials, and finishes in both metric and inch sizes.

These Threaded Flanges are manufactured in various materials including Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel, Inconel, Monel, Hastelloy, and Copper Nickel. They are supplied across India and Asia and conform to standard industrial specifications.

Threaded flanges are widely used in low-pressure piping systems since they do not require welding for installation. They are similar to slip-on flanges but feature internal threads in the bore that allow them to be easily assembled with pipes that have external threads.

Also known as screwed flanges, threaded flanges provide a convenient solution for systems where welding is not suitable or where disassembly may be required for maintenance and inspection.

No welding required for installation
Suitable for low pressure piping systems
Internally threaded bore for easy pipe connection
Available in carbon steel, stainless steel & alloy materials
