What Is Pipe Flange?
A pipe flange is a device, which connects different pipes, valves, fittings, and other components in a piping system. These flanges act as a support system as there is a vigorous movement of fluids or gases across the system. These protruding ridges securely connect pipelines and prevent any leakage within the systems. The mounting procedures of these components are simple and allow for easy dismantling procedures. They can also be welded in place however, this will not allow them to be inspected or cleaned if the need arises. There are several flange standards, which are used in the piping industry to meet different requirements.
What Is Slip On Flange?
Slip-on flanges are one of the most popular and common flange components used within the piping industry. These flanges are designed with a low profile head or hub, which is attached to the line making use of one or more fillet welds. The size of the bore is larger than the connecting area. They are mainly used in low-pressure systems where the risk of leakage is low. These components are also utilized in applications where the space for installing the fitting is less. The cost of fitting these components is very low making, them highly desirable. Apart from this, they are available in an array of shapes and sizes, which allow them to be fitted in different applications.
Flange International Standards
International Organization for Standardization (ISO) is a federation of worldwide national standards of flanges. The international standards lay down the basic dimensions, surface finish, material, facing type, and other technical information about flanges. The flange standards in Europe are governed by the European EN 1092 series. According to the series, steel flanges have nominal diameter and pressure between PN 2.5 to PN 400. Another European flange standard is the EN 1759, which only consists of ASME and ANSI flanges. The American flanges are standardized, comprising of ASME flanges and DIN flanges (PN 2.5, 6, 10, 16, 25, and 40). It also specifies the PN and DN designations for ASME flanges (PN 20, 50,110, 150, 250, and 420).
