Swage Nipple and Bull Plugs Manufacturers, Suppliers, Stockist – MSS SP-95, BS 3799 – ASTM A105, A182 F304, F316, F304L, F316L, and A182 F5, F9, F11, F22, F91

Swage Nipple is a kind of pipe reducer product that is used to connect pipes in different dimensions. It has various end forms and TBE (threaded both end) type is very prevalent among concentric swage nipples. Metallica is a well known manufacturer and supplier of Swage Nipples, Bull Plugs, Concentric Swage Nipple, Eccentric Swage Nipple, and NPT/BSPT Threaded Swage Nipples for the clients from oil and gas, petrochemicals, railway, construction and other industries. Swage nipples may be made to special dimensions, size, shape, tolerances, or of other wrought material by agreement between the manufacturer and the purchaser. We can produce swage nipples in size range of 1/2″ to 8″. The most common and materials include ASTM A105, ASTM A182 F304, F316, F304L, F316L, and A182 F5/F9/F11/F22/F91. In nickel alloys we manufacturing swage 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
  • MSS SP-97 – Integrally Reinforced Forged Branch Outlet Fittings –Socket Welding, Threaded, and Buttwelding Ends

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.
