High Pressure ASTM A105 DIN50 Carbon Steel Forged Slip On Flange
Slip on Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of slip on flange is also welded on the back side of the flange.
WHAT ARE SLIP-ON FLANGES?
Among the wide variety of forged flanges are some sliding types commonly called slip-on flanges. This is a type of flange that is low-cost and easy to install.
Main characteristics of the slip-on flange
Slip-on flanges are known for their low materials cost and easy installation. One of the added advantages of these flanges is that they can also be used as lap-joint flanges if Type B or Type C ends are being handled.
There is a wide range of diameters and low-pressure models to choose from. Unlike welding neck flanges, slip on flange does not have a neck to rest on the pipe, and therefore double welding is necessary.
A slip-on flange is connected to the pipe or the fittings by two fillet welds, one executed inside and one outside the cavity of the flange.
The bore size of a slip-on flange is larger than the outside diameter of the connecting pipe, as the pipe has to slide inside the flange to be connected by the execution of a fillet weld.
Slip-on flanges are also defined “Hubbed Flanges” and they are easy to recognize due to their slim and compact shape.
The dimensions and weights of slip-on flanges ANSI/ASME are available on this page.
WELD NECK VS SLIP ON FLANGE
Flanged joints made with slip-on flanges are, in the long run, a bit more fragile than connections made with welding neck flanges . This seems due to the following facts:
a welding neck flange features a tapered hub, absent in a socket weld flange, which distributes the mechanical stress between the pipe and the flange more evenly
a welding neck joint as only one welding area instead of two (socket weld flange).
Another advantage of the welding neck flange is that it can be connected either to pipes and fittings, whereas socket weld flanges suit pipes only.
