ASME B16.11 ASTM A350 LF2 SW Elbow Socket weld elbow tee Pipe fittings
We can produce high quality ASME B16.11 3000# /6000#/9000# ASME B16.11 ASTM A350 LF2 Thread Elbow,NPT Threaded elbow,tees, couplings, caps, plugs, bushings, unions and nipples.
An ASTM A350 LF2 SW elbow is a type of socket weld elbow fitting made from ASTM A350 LF2 material, commonly used in low-temperature, high-pressure applications. The “SW” stands for Socket Weld, indicating that the pipe is inserted into the fitting and welded along the circumference, creating a strong, secure connection.
ASTM A350 LF2 is a low-temperature carbon steel forged grade material widely recognized for its exceptional toughness, impact strength, and corrosion resistance .
Dimensions to ANSI B16.11/BS3799
BS EN 10204 3.1 Certificates will be provided
ASME B16.11
is the This Standard covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded forged fittings. These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings. B16.11 is to be used in conjunction with equipment described in other volumes of the ASME B16 series of standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.
