Lap Joint Flange is a pipe fitting widely used in industrial pipeline connections.

1. Structural features

Components

Lap Joint Flange is mainly composed of a flange and a flanged nipple. The flange is a common disc-shaped structure with bolt holes on it for connection with other flanges or components. The flanged nipple is connected to the pipeline at one end and matched with the flange at the other end.

Connection method

Its connection with the pipeline is relatively unique and is not directly welded to the pipeline. Usually, the flanged nipple is put on the pipeline and fixed to the pipeline by welding or other connection methods (such as crimping connection). The flange and the flanged nipple are a loose connection relationship, allowing a certain relative movement between the two.

2. Performance advantages

Adapt to deformation

Due to its loose structure, the Lap Joint Flange can adapt well to the axial displacement of the pipeline when the pipeline system undergoes thermal expansion and contraction or vibration. This can effectively avoid excessive stress at the connection part due to pipeline deformation, thereby reducing the risk of pipeline damage and extending the service life of the pipeline system.

Easy maintenance

When the pipeline needs to be inspected, repaired or replaced, the structure of Lap Joint Flange makes the operation more convenient. There is no need to perform complicated cutting and re-welding like some welded flanges. You only need to remove the connecting bolts to easily separate the flange from the flanged short section, and then perform the corresponding operation on the pipeline.

Cost-effectiveness

In some large pipeline systems or projects with high requirements for pipeline connection flexibility, Lap Joint Flange can reduce installation costs and subsequent maintenance costs. Its simple installation method can reduce installation time and labor costs, and its easy maintenance characteristics also reduce the additional costs caused by maintenance.

3. Application fields

Lap Joint Flange is widely used in pipeline systems in many industrial fields such as chemical, petroleum, natural gas, electricity, and pharmaceuticals. In the chemical and petroleum industries, since the transported media are often corrosive, high temperature and high pressure, the pipeline system needs to cope with complex working conditions. Lap Joint Flange can adapt to these requirements well and ensure the reliability and safety of pipeline connections. In the power industry, it is used for pipeline connections that are sensitive to thermal expansion such as steam pipelines. In the pharmaceutical industry, it meets the requirements of clean pipeline systems for easy maintenance.
