Loose Flange

Loose flange is a type of flange connection that is characterized by a certain degree of mobility or removability of the connection between the flange and the pipe or equipment. This type of connection allows the flange to be easily Loose flange is widely used in a variety of industrial fields, especially in situations that require frequent disassembly and replacement of equipment. It allows the pipeline or equipment to be moved and adjusted to a certain extent without being restricted by the flange, thus improving the flexibility and adaptability of the system.

Product Description

Features and Advantages

High mobility: because the connection between the flange and the pipe or equipment is loose, the loose flange has a high degree of mobility. This mobility makes the flange more adaptable to cope with small movements and deformations of the pipe or equipment.
Ease of disassembly: Compared to fixed flanges, loose flanges are easier and quicker to disassemble and reassemble. This greatly reduces the cost of maintenance and time spent on equipment.
Adaptable: loose flange can be adapted to different sizes, shapes and materials of pipeline or equipment connection needs. This makes it widely applicable in various industrial applications.

Often used as a connection is a change in material

The loose flange is sleeved on the pipe end by using a flange, a steel ring, etc., and the flange can be moved on the pipe end. Steel rings or flanges are the sealing faces, and the flanges act to compress them. It can be seen that the loose flange is not in contact with the medium due to being blocked by the steel ring or the flange.

The loose flange is suitable for the connection and corrosion-resistant pipelines of non-ferrous metals such as steel and aluminum and stainless acid-resistant steel containers.
The loose flange is a movable flange. It is usually matched on the water supply and drainage fittings (the most common on the expansion joint). When the factory leaves the factory, there is a flange at each end of the expansion joint, which is directly related to the pipeline and equipment in the project. Connected by bolts.
It is the kind of flange with a looper. It is generally used on pipes, in which case the bolts can be rotated to rotate the pipes on both sides and then tightened. It is convenient to disassemble the pipe. Loose flanges are also called loop flanges.

The connection of the loose flange is actually achieved by welding, except that the flange is loosely attached to the attached component that has been welded to the pipe, and then the attachment component and the gasket are pressed by the connecting bolt to achieve sealing. The flange (ie the loose sleeve) itself does not touch the medium.
The attachment of the accessory to the tube is either flat or butt welded.

Cautions

Sealing: Although the loose flange has the advantages of high mobility and easy disassembly, attention needs to be paid to its sealing performance in practical applications. If the sealing at the flange connection is not tight, it may lead to leakage problems. Therefore, it is necessary to ensure the sealing of the flange connection during installation and use.
Strength requirements: Since the loose flange needs to withstand certain pressure and temperature fluctuations, it is necessary to ensure that its strength meets the actual needs in the selection and use. Avoid flange damage or failure in the process of use.
