ASME B16.5 Flange
ANSI/ ASME B16.5 Flange is the specification and standard for stainless steel flanges that range between ½ inches and 24 inches in outer diameter. These are used in different types of applications such as water lines, food processing industries, power generation and sea water applications. The ASME B16.5 Flanges is used to connect two parts of a piping structure together with a raised surface to allow for more attachment by welding or to have bolt holes. There are different types of flanges such as the Class 150 Flanges which is used to terminate a pipe line.

The blind flanges can either be welded to make a permanent closure or be bolted for a temporary closure of the pipes. The ASA B16.5 flange also can be of different types by means of production method and applications. There are socket weld, neck weld, butt weld and other types of flanges. The most commonly used Class 300 Flanges is the buttweld flange because of its ease of application. Sometimes when the application needs a stronger connection through welding of the flange, the ASME B16.5 weld neck flange is deemed suitable. Please make sure to know all about your flanges by contacting us.
