What is a Lap Joint Flange?

A lap joint flange is a pipe flange welded to the lap joint stub end. The lap joint flange has a raised face and a small bore. The lap joint flange is used in applications where it is not possible to weld the pipe to the stub end.

A lap joint flange is a type of flange designed to connect pipes with a lap joint. Lap joints are used when there are no other options, such as when the pipe must be inserted into an existing line, or when the pipe has been cut at an angle and cannot be welded.

Different Types of Lap Joint Flanges

Lap joint flanges are generally used in low-pressure piping applications. They can be classified into two types: lap-end and stub.

Lap-end flanges are attached to the pipe by welding the lap joint stub to the pipe. The other end of the flange is free to rotate, making it ideal for use in applications where alignment is an issue. On the other hand, stub flanges are welded directly to the pipe. This makes them more rigid, less likely to leak, and more challenging to install and align.

Advantages and Disadvantages of Lap Joint Flange Usage

Lap joint flanges are one of the most popular types of pipe fittings. They are used in various industries and have many advantages and disadvantages.


1. Lap joint flanges are versatile and can be used in various applications.

2. They are easy to install and don’t require welding or other complex installation procedures.

3. Lap joint flanges provide a good seal and are resistant to leaks.


1. Lap joint flanges can be expensive, depending on the material they’re made from.

2. They’re not as strong as other pipe fittings so they could be better for high-pressure applications.

3. Lap Joint Flange is often used in a piping system to create a joint between two pipes. The flange is bolted or welded to one of the pipes. The other pipe is bolted or welded to the other side of the flange.

The advantages of lap joint flanges are that they are simple and easy to install, used for any size of pipe, and can be applied in any position. The disadvantage is that when pressure is applied, it often causes leaks on one or both sides of the joint.

How to Choose the Right Lap Joint Flanges for Your Project Needs?

When working on a piping project, choosing the right lap joint flanges are essential. Lap joint flanges can be used to join two sections of pipe and provide a secure connection. The type of flange you need will depend on several factors, including the material used in the pipes and the surrounding environment.

Here are some tips to help you select the right lap joint flange for your project needs:

First, consider what type of material will be used in your flanges. Different materials require specific lap joint flanges to ensure a secure connection. For instance, stainless steel, aluminum, and carbon steel. Consider all materials before making your selection to choose the most suitable option for your project needs.
