Features

The main difference between plate loose sleeve flange and ordinary plate flange is that there is a loose sleeve at the center of the flange, which is a non welding method, and its inner diameter is relatively larger.

Loose sleeve is a part of the flange that matches the outer diameter of the pipeline and is usually fixed to the pipeline by bolts or nuts.

This design makes the installation and disassembly of flanges more convenient, especially suitable for situations that require frequent maintenance, repair, or replacement.

Advantages and disadvantages

Advantages

1. Easy to install and disassemble: The loose sleeve design allows the flange to easily slide on the pipeline, making it easier to install and disassemble. It is suitable for situations that require frequent maintenance, repair, or replacement.
2. Flexibility: Loose flange allows for slight pipeline expansion and deformation, improving system flexibility, especially suitable for applications that need to adapt to pipeline deformation.
3. Convenient maintenance: With a loose sleeve, it allows for easier access to the interior of the pipeline system, which helps with maintenance and repair work.
4. Low cost: Compared to some more complex flange designs, plate flanges with loose sleeves may be more cost-effective.

Disadvantages

1. Relatively poor sealing performance: Compared to some other flange designs, the sealing performance of loose flange may be relatively poor. In some situations where sealing requirements are extremely high, additional sealing measures may be required.
2. Restricted by temperature and pressure: Loose flange may be subject to some limitations in high temperature and high pressure environments. In these cases, it may be necessary to consider other flange types that are more suitable for high temperature and high pressure requirements.
3. Challenge in selecting loose sleeve size: The design of loose sleeves requires precise matching of pipeline diameter, and improper selection may lead to weak connections or poor sealing.

Usage:

Mainly used to connect pipelines, valves, equipment, etc., suitable for systems that require frequent maintenance or replacement. It can provide reliable connections while facilitating system maintenance work.

Application areas:

Widely used in various industrial fields such as chemical, petroleum, natural gas, and water treatment. Especially in situations where quick disassembly or replacement of components is required, plate flanges with loose flanges can improve the convenience of operation.
