A 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.

Forged Socket Weld & Threaded Pipe Fittings Manufacturing Standards

  • ASTM A182 – ASME SA182 – Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings
  • ASME B16.9 – Factory-Made Wrought Buttwelding 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-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

Socket weld and threaded fittings are generally used for small size pipes and piping systems (generally below 4 inches in diameter for Class 3000, and below 2 inches for fittings in class 6000 and 9000). Forged pipe fittings are manufactured by forging, followed by heat treatment and machining solid steel as per the dimensional standards. For bigger size piping systems buttweld pipe fittings produced as per ASME B16.9 are used.
