Metallica is a well known manufacturer and supplier of socket weld reducing inserts for the clients from oil and gas, petrochemicals, railway, construction and other industries. We manufacture different size of socket weld reducing inserts by closed die forging. Our main products include various types of socket weld pipe fittings in size range of 1/4″ to 4″ (6mm-100mm), with pressure rating of 2000LBS, 3000LBS, 6000LBS, and 9000LBS. 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 are manufacturing socket weld pipe fittings 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

Socket weld pipe 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). Socket weld pipe fittings are manufactured by forging, followed by heat treatment and machining solid steel as per ASME B16.11 and other dimensional standards. For bigger size piping systems buttweld pipe fittings produced as per ASME B16.9 are used.
