Socket Weld and Threaded Fittings B16.11

Socket Weld and Threaded Fittings conforming to ASME B16.11 are essential components in piping systems, used for connecting pipes and enabling changes in direction or branch connections. These fittings are designed for high-pressure applications and come in various material grades. Below is a comprehensive overview of the specifications, types, and grades for both socket weld and threaded fittings per ASME B16.11.ASME B16.11 Socket Weld and Threaded Fittings1. Overview• Standard: ASME B16.11• Types: Socket Weld Fittings and Threaded Fittings• Material Grades: Includes Carbon Steel, Alloy Steel, Stainless Steel, and others2. Types of FittingsSocket Weld Fittings:• Elbows: Used to change the direction of the pipe.o 90° Elbowo 45° Elbow• Tees: Used to connect three pipes.o Equal Tee: All three outlets are the same size.o Reducing Tee: One outlet is a different size.• Couplings: Used to join two pipes of the same size.o Full Couplingo Half Coupling• Unions: Allow for easy disconnection.• Plugs and Caps: Used to seal the end of a pipe or fitting.Threaded Fittings:• Elbows: Used to change the direction of the pipe.o 90° Elbowo 45° Elbow• Tees: Used to connect three pipes.o Equal Teeo Reducing Tee• Couplings: Used to join two pipes of the same size.o Full Couplingo Half Coupling• Bushings: Reduce the size of a fitting.• Plugs and Caps: Used to seal the end of a pipe or fitting.• Unions: Allow for easy disconnection.4. Material GradesSocket Weld and Threaded Fittings:• Carbon Steel:o ASTM A105: Standard for forged carbon steel fittingso ASTM A350 LF2: Low-temperature carbon steel• Alloy Steel:o ASTM A234 WP1, WP11, WP22, WP91: Alloy steel fittings for high-temperature service• Stainless Steel:o ASTM A182 F304, F304L: Standard for stainless steel fittingso ASTM A182 F316, F316L: For higher corrosion resistance5.
