What Is Lap Joint Flange?
A Lap Joint Flange can be described as a two component assembly, which comes with a stub end and a ring flange placed on top of it. The stub end is basically buttwelded to the pipe, and the flange ring is rotated so that it can be perfectly aligned with the mating flange. They are mostly used for flanges that are hard to adjust or large. They are used in similar sizes and pressure classes as that of the weld neck flange.
The cost and the application environment where the Lap Joint Flange can be efficiently used depend on the material grade. They are available in customizable dimensions, which makes it easy to integrate them with any existing pipe or piping components. However, it is essential to remember that the biggest limitation of Lap Joint Flange is in its pressure ratings. They undoubtedly bear greater pressure than the slip-on flanges, but they are not perfect to be used in high pressure applications.
One of the best things about Lap Joint Flange is that the flange can be realigned and rotated freely. This helps in ensuring proper connection and it also ensures that the maintenance process is carried faster. As it does not require fillet weld for joining with the pipe, this reduces the installation time and helps in saving money. They can be used in highly corrosive or erossive processes as its parts can be replaced easily which ensures cost-effective operation.
Is A Stainless Steel Lap Joint Flange is Raised Face?
The Lap Joint Flange comes with a unique design due to which it always has a flat face that is accompanied by a smooth surface. But when accompanied by stub ends, the resultant sealing would have a raised face. It is because the stub end’s sealing face is above the bolting surface of the flange. Thus, the Stainless Steel Lap Joint Flange is Raised Face.
How To Install Carbon Steel Lap Joint Flange
The installation process of the Carbon Steel Lap Joint Flange is fairly simple. All you need is a few screws and you can install the flange to the pipe. The bolts are placed through the holes present in the flange and then they are tightened clockwise to improve their grip.
What Are The Advantages And Disadvantages Of A Lap Joint Pipe Flanges?
The Lap Joint Pipe Flanges come with a two-piece configuration, which has its own benefits. The stub end can be made from expensive material grade while the backing flange can be made from common carbon steel. This makes the flanges very cost-effective. Also, as the flange is not welded to the pipe, it can be rotated to be aligned and bolt the holes. This makes assembling and disassembling easier. Thus, they are ideal for piping operations that require frequent disassembling for inspections or maintenance.
There are also some Disadvantages Of Lap Joint Pipe Flanges, due to the design, contaminants might get collected easily, which could result in crevice corrosion. Also the longitudinal stress might accumulate and exceed the basic stress limit of the given standard. Thus, they are always used for mild services. Also, sometimes the material grade of the stub end might be different from that of the flange to save some cost, but this might cause galvanic corrosion in some cases.
Loose Flange Vs Lap Joint Flange
The loose flange is a synonym of the lap joint flange, and hence there is no difference between them.

A lap-joint flanges is a two-part assembly that consists of a stub end with a lap-joint ring flanges placed over it. After butt welding the stub end to the pipe, the flange ring can be rotated to align with the mating flange. This flanges connection is especially useful for large or difficult-to-adjust flanges.
