Lap Joint flanges are used on piping fitted with lapped pipe or with lap joint stub ends. The lap joint flange with the stub end assembly are normally used in systems requiring frequent dismantling for inspection and cleaning and where the ability to swivel flanges and to align bolt holes materially eases the erection of large diameter or unusually stiff piping. These flanges are also used in applications where there is a need to facilitate bolt alignment. These type of flanges are similar to slip-on flanges. The only difference is that it has a curved radius at the bore and face to accommodate a lap joint stub end. They may be used at all pressures and are available in a full size range. These lap joint flanges slip over the pipe, and are not welded. They are otherwise fastened to it. Here the bolting pressure is transferred to the gasket by the pressure of the flange against the back of the pipe lap.

These are as follows: Lap Joint flanges have the freedom to swivel around the pipe. This facilitates the lining up of opposing flange bolt holes. Lack of contact with the fluid inside the pipe leads to the greater durability of these flanges. In piping systems which corrode or erode quickly, the lap joint flanges may be salvaged for re-use. The pressure-holding capacity of lap joint flanges is little. But it is better than that of slip-on flanges. The Lap Joint works as a backing ring on the stub. The main advantage of lap joint flange is that the bolt holes can be aligned with the matching flange after the welds have been completed. They allow rotational alignment capability.

Lap Joint Flange

Lap joint flanges feature a flat face and are always used in conjunction with a stub end. Lap joint flanges resemble, in shape, slip-on flanges except for the radius at the crossing of the flange face and the bore to accommodate the flanged portion of the stub end. A lap joint flange slips over the pipe and seats on the back of the stub end and the two are kept together by the pressure of the bolts. The use of lap joint flanges in combination with stub ends is a cost-effective solution for stainless steel or nickel alloy pipelines, as the material of the lap joint flange can be of a lower grade (generally carbon steel) than the material of the stub end (which has to match the pipe grade, as in contact with the conveyed fluid). This arrangement, therefore, has these two advantages: reduces the overall cost of the pipelines flanged joints, as the use of higher grade materials is minimized; bolting operations are simplified, as the lap joint flange can be rotated around the pipe to help with bolts alignment.

As the name suggests, stainless steel flanges are flanges made of an alloy called stainless steel. Here is why stainless steel flanges are worth your investment: Corrosion resistance : Corrosion is a major problem for clients using flanges due to chemicals and environmental factors. Therefore, it is ideal to choose stainless steel flanges that can withstand these conditions. Stainless steel is a great choice as it is highly resistant to corrosion. Durability: Stainless steel is one of the most durable alloys and can withstand harsh environmental conditions. Tolerance to extreme temperatures: Flanges made of stainless steel can withstand high temperatures. Some grades can withstand scaling and can maintain their strength even at very high temperatures, while others show excellent durability at extremely low temperatures. Aesthetics: Stainless steel flanges are available in a variety of surface finishes which gives them an aesthetic look. It is easy to clean and maintain, resulting in high quality, attractive appearance. Stainless steel flanges are available in a wide variety of grades of stainless steel. Each grade differs in chemical composition and has different properties. There are various grades of stainless steel flanges available to suit the client's requirements. One must put its intended applications into consideration when choosing the grade of stainless steel flange to use. For example liquids, gases, etc.)
