Hex Nipple Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Hex Nipple in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, in a wide range of sizes and pressure ratings.
A hex nipple has male threads on both ends with a hex in the centre, used to join two female-threaded fittings.
Threaded (screwed) fittings are forged fittings with internal or external pipe threads, allowing small-bore piping to be assembled and dismantled without welding. They are used in utility, instrument, air, water and low-to-medium pressure process lines.

Related Threaded Fittings
Threaded 90 Degree Elbow
A threaded 90° elbow makes a right-angle turn in small-bore piping with female threads on both ends.
Threaded 45 Degree Elbow
A threaded 45° elbow provides a 45° change of direction in screwed piping systems.
Threaded Street Elbow
A street elbow has a male thread on one end and a female thread on the other, so it screws directly into another fitting and saves a nipple.
Technical Note: Dimensions, pressure ratings and material properties should be verified against the applicable ASME / MSS / DIN / ISO standard, approved drawings, purchase order and Mill Test Certificate (MTC) before final use.
