Steel hoop flanged loose-bolt flanges are a special type of flange, primarily used for pipeline connections. These flanges feature the ability to rotate the pipe by loosening the bolts, making installation and removal convenient. Below are some detailed descriptions about the steel hoop flanged loose-bolt flanges:

Structure and Features

Structure:

The loose flange consists of two parts: the pipe section and the flange disc.

The pipe section is connected to the pipeline at one end and the other end is formed into a flange or a welded ring.

The flange is partially fitted onto the flanged or welded ring, secured by bolts.

Features:

Cost-saving: When the pipe material is special and expensive, welding flanges of the same material can be costly. Loose-bolt flanges can utilize lower-grade flanges, thereby saving costs.

Easier installation: The loose fit flange is very convenient when aligning bolt holes during connection or when preventing changes in bolt hole alignment of the flange for future equipment replacement.

Not suitable for welding or processing: Suitable for materials that are not easy to weld or process, such as plastic pipes, steel-reinforced glass pipes, etc.

Easy for inspection and cleaning: The loose-fitting flange is simple to install and dismantle, making it convenient for inspection and cleaning.
