A pipe nipple is a short length of pipe with male pipe threads at both ends for connecting other fittings. You may also see them referred to as “barrel nipples”. Generally there is a short distance of unthreaded pipe between the two threaded ends. When there is no bare pipe between the two connecting ends, the part may be called a “close nipple” or a “running nipple”. Metallica is a well known manufacturer and supplier of pipe nipples and hex nipples for the clients from oil and gas, petrochemicals, railway, construction and other industries. Our main products include socket weld fittings, threaded fittings and pipe nipples in size range of 1/4″ to 4″ (6mm-100mm). The most common materials for manufacturing pipe nipples and hex nipples are carbon steels, stainless steels, alloy steels and non-ferrous metals certified to ASTM, ASME and DIN standards. In nickel alloys we are manufacturing pipe nipples in various grades such as Alloy 200, 201, 400, K500, 600, 625, 800H/HT, 825, X-750, C276, Hastelloy B & C22.
Pipe Nipple and Hex Nipple Manufacturing Standards
- ASTM A182 – ASME SA182 – Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings

- ASME B16.11 – Socket Welding and Threaded Forged Fittings
- MSS SP-43 – Wrought and Fabricated Butt-Welding Fittings for Low Pressure, Corrosion Resistant Applications
MSS SP-79 – This standard complements ASME B16.11, providing additional requirements for forged fittings, including hex nipples.
- MSS SP-95 – Swage(d) Nipples and Bull Plugs
- BS3799 – Specification for Steel pipe fittings, screwed and Socket-welding for the petroleum industry
- MSS SP-83 – Socket Welding and Threaded Steel Pipe Unions
- DIN2982 – This German standard focuses on the design, manufacture, and testing of pipe nipples, ensuring interchangeability and reliability.
- Common materials for pipe and hex nipples include carbon steel (ASTM A105), stainless steel (ASTM A182), and alloy steels.
- Stainless steel grades like 304 and 316 are used for applications requiring corrosion resistance.
- Non-ferrous metals like brass and copper are also used in certain applications.
