What is ASME B16.5 Flange?
The ASME B16.5 specification is basically limited to flanges and flanged fittings. They are either made from forged or cast materials. Different types of flanges can be made with the given material specifications. They are also available in different pressure classes and made from plate material. The standard also meets the recommendations and requirements for flange bolting, flange joints and flange gasket.
The ASME B16.5 Flange’s standard is used along with the equipment, as described in the other volumes of ASME B16 series standards. For example, the ANSI B16.5 forged flanges of pressure class 150 are used with boilers or pressure vessel code along with B31 piping code.
What are the Types of Flanges?
There are several types of flanges like:
Why are flanges needed in piping?
The flanges are primarily used for connecting pipes, valves, pumps, and various other equipment to complete the piping system. Flanges can be welded or threaded to join with the pipe. Two flanges can also be bolted together with the help of a gasket so that the piping system is sealed safely so as to work with efficiency.
ASME B16.5 Class 300 Flanges Vs ASME Class 600 Flanges
The primary difference between ASME B16.5 Class 300 Flanges and ASME Class 600 Flanges, is in their pressure classes. They have different dimensions, except for the bore. The class 600 flanges are heavier and they can also be rated for a high pressure, compared to the class 300 flanges. They have a different outside diameter for both the flanges.
