Forged & Plate Flanges

The Flange is slipped over the pipe or tube and welded (usually both inside and outside) to provide strength and to prevent leaks. These flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe or tube to length. They can sometimes have a boss or hub, and can be made with a bore to suit pipe or tube.

Material Grade:

This is similar to a slip-on Flange in outline, but the bore is counter- bored to accept the pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The Flange is attached to the pipe by a fillet weld around the hub of the Flange. An optional internal weld may be applied in high stress applications. Its biggest use is in high-pressure systems such as hydraulic and steam lines.

Material Grade:

This is a Flange without a bore and is used to shut off a piping system or vessel opening. It also permits easy access to vessels or piping systems for inspection purposes.

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.

Material Grade:


Lap Joint flanges have certain special advantages over other flanges. 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.
