Loose sleeve flanges are commonly used as connections for material changes.

The loose sleeve flange is the use of flanging, steel ring, etc., to put the flange on the tube end, and the flange can be moved on the tube end. The steel ring or flanging is the sealing surface, and the role of the flange is to press them. It can be seen that the loose sleeve flange does not contact the medium because it is blocked by the steel ring or flanging.

The loose sleeve flange is suitable for the connection of steel, aluminum and other non-ferrous metals and stainless acid-resistant steel containers and corrosion resistant pipelines.

The loose sleeve flange is a movable flange, which is generally matched on the water supply and drainage accessories (the most common on the expansion joint). When the manufacturer leaves the factory, each end of the expansion joint has a flange, which is directly connected with the pipe and equipment in the project.

Product Parameters

Advantages:

1. Cost savings. When the pipe material is special and the price is expensive, the cost of welding the flange of the same material is high.

2, not easy to weld or not easy to process or the strength required. Such as plastic pipe, glass steel pipe and so on.

3, easy to construct. For example, it is not easy to find the corresponding flange bolt holes during connection or prevent the flange bolt holes of the equipment from changing in the future.

Shortcoming:

1, low pressure.

2, low strength at the welding ring (especially when the thickness is below 3mm)
