Screwed / Threaded Flanges Manufacturer & Supplier

Sawariya Metal Industries manufactures, supplies, stocks and exports a wide range of industrial flanges and piping components. Our Screwed / Threaded Flanges are designed for applications where a flanged connection is required without welding the flange directly to the pipe.

Screwed / Threaded Flanges feature an internally machined thread that mates with the external thread of a compatible pipe. This configuration can be useful for selected piping systems where welding is undesirable, impractical or restricted by the application.

These flanges are available in different materials, sizes, pressure classes, standards and face configurations for industrial requirements. Applications include process piping, fabrication, marine, chemical, petrochemical, oil & gas, sugar, defence and other industrial sectors.
