This specification for ASME B16.11 Threaded Union covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts that have been designed for use in high-temperature applications. After hot working the Threaded Union Dimensions, these forgings need to be cooled to a specific temperature. Cooling the ASTM A182 SS Threaded Unions has to be done prior to heat treatment, which again must be performed in accordance with certain requirements. According to the specification the Alloy Steel Forged Screwed Union has parameters such as heat treatment type, austenitizing/solution temperature, cooling media, and quenching. The Threaded Fittings Union materials are intended to conform to the required chemical composition for carbon, molybdenum, columbium, titanium, manganese, phosphorus, silicon, nickel, chromium. The material of the BS3799 Screwed Forged Union shall conform to the requirements as to mechanical properties for the grade ordered such as yield strength and tensile strength, elongation as well as Brinell hardness. All H grades and grade F 63 for the Screwed Union shall be tested for average grain size.

The specification for ANSI B16.11 Forged Threaded Union Standard covers ratings, dimensions, tolerances, marking and material requirements that is meant for socket-welding and threaded forged fittings. These fittings such as the Stainless Steel Threaded Union are designated in the following pressure classes -  Class 2000, 3000, and 6000 for threaded end fittings and while pressure classes -  Class 3000, 6000, and 9000 have been designated for socket-weld end fittings. The ASME B16.11 Forged Threaded Union is to be used in unification with equipment described in other volumes of the ASME B16 series of standards. Besides these standards. B16.11 can also be used with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.

Dielectric Alloy Steel Forged Screwed Union, with dielectric insulation, produced from separate dissimilar metals such as copper and galvanized steel aid in preventing galvanic corrosion. A dielectric Forged Threaded Union generally breaks the electrical path with a plastic liner between its halves, limiting galvanic corrosion. Rotary 3000LB Threaded Union allow mechanical rotation of one of the joined parts, while resisting leakage.


What is ASME B16.11 Threaded Union?


ASME B16.11 Threaded Union

Although a SS 310 Threaded Union connects two pipes, but is quite different than a coupling. This is because the Threaded Forged Union allows for future disconnection of the pipes in during the time for its maintenance. Contrary to a coupling requiring solvent welding, soldering, or rotation (for threaded couplings), a Forged Screwed Union allows for both easy connection as well as easy disconnection, multiple times if required. The Screwed Union 3000LB Threaded consists of three parts: 1. a nut, 2. a female end, and 3. a male end. When the female and male ends are joined in the Duplex Steel Threaded Unions, the nut will seal the joint by pressing together the two i.e. - female and male ends tightly. ASME B16.11 Threaded Union could also be considered as a type of very compact flange connector.

ANSI B16.11 Forged Threaded Union Weight Chart


ANSI B16.11 Forged Threaded Union Weight Chart

Different Screwed Union sealing types are selected industry wise such as many pressure systems onboard ships use BSPP Forged Threaded Union while many applications in the oil and gas industry use NPT BS3799 Screwed Forged Union. NPT Thread ANSI B16.11 Forged Threaded Union is an American Standard Taper Pipe Thread as per ANSI/ASME B1.20.1.


We produce Stainless Steel Threaded Union in below two most common standards for tapered threads


  • NPT American National Standard Taper Pipe Thread SS 310 Threaded Union
  • BSPT British Standard Pipe Taper Thread Threaded Forged Union

Why use NPT ASME B16.11 Forged Threaded Union?


  • Forged Screwed Union NPT threads have an angle of 60°
  • NPT threads also have flattened peaks and valleys

Why use BSPT Screwed Union 3000LB Threaded?


  • BSPT threads have an angle of 55°
  • Compare to NPT aaaaaaa BSPT threads have rounded peaks and valleys

Duplex Steel Threaded Unions Threads:


  • NPT : National Pipe Thread Taper
  • FPT, FNPT, NPT(F)* Female or internal tapered pipe threads
  • MPT, MNPT, NPT(M) Male or external tapered pipe threads
  • BSPT: British Standard Pipe Taper
  • BS 21: British Standard Pipe Taper
  • DIN 2999: Pipe Threads for Tubes and Fittings
  • PT: Japanese Industrial Standard (JIS) Tapered Pipe Thread
  • ISO 7-1: Pipe Threads where Pressure-Tight Joints are made on the Threads
  • DIN 158: Metric External Taper Screw Threads and Mating Internal Parallel Screw Threads
