A lap joint flange is one that slides directly over the pipe. These types of flanges are used in applications that call for regular dismantling. Lap joint flanges are basically two piece devices that are very akin to loose slip-on flanges and weld-neck flanges. Lap joint flanges are used a lot with stub end fittings. The stub end will have a pipe welded to it and the lap end type of flange can thus freely rotate around the end of the stub. With this kind of an arrangement, there is no issue experienced with bolt hole alignment. There are various advantages to using carbon steel lap joint flanges. One of these is that as a result of using such types of flanges, there is no contact with the fluid in the pipe. And this allows for the usage of inexpensive carbon steel flanges when corrosion resistant pipes are used.

Another advantage to using lap joint flanges is that though they have a little pressure-holding capacity, it is much better than that of slip-on flanges. One of the biggest advantages of using a stainless steel lap joint flange is that this kind of flange is highly resistant to corrosion. Lap joint flanges made of stainless steel have an excellent life cycle and they are highly resistant to heat and cold temperatures. Stainless steel lap joint flanges are environment-friendly and they are also 100% recyclable. The use of lap joint flanges allows for freedom of swiveling around the pipe and this, in turn, allows for the lining up of bolt holes of opposing flanges. Another big advantage to using lap joint flanges is that with this type of flange, it becomes possible to align the bolt holes with the matching flange, after completion of the welds.

Raised face lap joint flange is also known as RF lap joint flange and this kind of flange is extremely easy to identify. RF lap joint flanges are the most commonly used type of flanges, in various kinds of process plant applications. RF lap joint flanges are called ‘raised face’ due to the fact that the surfaces of the gasket, are raised above the face of the bolting circle. During the process of dimensional inspection of lap joint pipe flanges, it is imperative to check for the length of the hub, the inner diameter and the outer diameter of the body, the alignment and straightness of the bolt hole and the bolt hole diameter/bolt circle. Lap joint flanges are primarily used in lined piping systems and on expansion joints. Basically, lap joint flanges have 2 parts, the backing flange, and the stub end. Lap joint flanges can be procured in various sizes, specifications, and material grades.

What is Lap Joint Flanges?

The Lap joint flanges use a stub end that is welded to the pipe. permitting easy flange alignment of the bolt holes. A lap joint flange is also called Van Stone or Stub Flange. A stub ends are available in three styles (Types A, B, and C) and two lengths (Short and Long).
