Pipe systems are constructed by connecting pipes, valves, pumps, and other equipment to form a pipe network. To provide a seal, they are bolted together with a gasket in between them. It has the advantage of being simple to clean, inspect, and modify.

The inner bore of the ASME B16.5 Socket Weld Flange has a recessed shoulder, which allows the pipe to be inserted correctly and easily welded. Because of this welding structural design, the liquid in the pipelines has a smooth bore and good transmission performance in Socket weld pipe flanges..

Flange according to ASME B16.5

Slip-on flanges, weld neck flanges, socket-weld flanges, threaded flanges, lap joint flanges, and blind flanges are all examples of ASME B16.5 pipe flanges. Flanged Fittings are pipe fittings that have flanges on the ends.

Forged flanges are available in sizes ranging from 1/2” to 24”, with pressure ratings ranging from class 150 to class 300, class 600 to class 900, class 1500 to class 2500. In order to be easily identified, they are typically shown with the material and standard in the marking.

What exactly is ASME B16.5?

The American National Standards Institute (ANSI) published the first version of the B16.5 standard in 1973. Prior to that, it was a standard set by the American Standards Association. ASME B16.5 became the standard in 1996.

Pipe flanges and flange fittings are specified in accordance with ASME B16.5, which is the industry standard. The American Society of Mechanical Engineers, which has been defining piping safety standards since 1922, was responsible for developing the standard.

For pipe flanges, this standard specifies the pressure-temperature ratings as well as the materials, dimensions, tolerances, marking, testing, and methods of designating openings.

Application of Socket Weld Flange

To begin with, forged socket weld flanges were designed for use on small-diameter, high-pressure piping systems. Their static strength is the same as that of Slip On flanges, but their fatigue strength is 50% greater than that of double-welded Slip On flanges, which is a significant advantage. They are primarily employed in the fields of boilers and pressure vessels, oil and gas, chemical industry, shipbuilding, metallurgy, and engineering.

Socket Weld Flange Welding is a type of welding in which a socket is welded to a flange.

After inserting one end of the pipe into the flange until it touches the shoulder, you should back the piping out between 1/16 inch and 1/8 inch. To prevent the expanding pipe on the inner side of the weld from expanding further, it is necessary to use this method. In comparison to a slip-on flange, only one fillet weld is required between the flange and pipe.
