Slip-on flanges have a hub with a very low profile. This type of flange is usually connected to a pipe by one or two fillet welds, it is however possible to use only a single weld.
The slip-on flange is a simple and reliable alternative to a weld neck as it does not have a weld bevel, and therefore allows the pipe to be adjusted in length relative to its position of the flange. The bore of the slip-on will give an ample amount of space for the matching pipe. This allows for enough working space for the welder and fabricator to make the connection.
Usually, slip-on flange can be made by forging, steel cutting, casting, etc. Among these manufacturing types, the forging type gains reliable quality and is also commonly used.
The advantages of sliding on the flange: (1) lower installation costs; (2) better leakage proof; (3) more easily consistent with other parts during installation; (4) internal and external welding on flange in flange ; (5) the accurate cutting of the pipeline requires less time; (6) as pipe slides on the flange, it can be well compatible.
