Lap joint flange features:

Lap joint flange is the use of flanging, steel ring, and another flange on the pipe end, the flange can be moved on the pipe end. The steel ring or flange is the sealing surface, and the flange is used to hold them down. It is easy to find that the lap joint flange is not in direct contact with the medium because it is blocked by the steel ring or flanges. That is why they are called lap joint flanges or loose-sleeve flanges.

Lap joint flange uses:

Lap joint flanges are suitable for the connection of steel, aluminum, and other non-ferrous metals and stainless acid-resistant steel containers and corrosion-resistant pipelines.

A lap joint flange is a movable flange piece, which is generally matched with water supply and drainage fittings (expansion joint is the most common). So for finished flanges, there is a flange at both ends of the expansion joint, which is directly connected with the pipeline and equipment in the project with bolts.

You know, the flange with the looper. It is usually used on pipes so that the live bolt can rotate the pipes on both sides and tighten them. It can be more convenient to disassemble and install pipes. lap joint flanges are also called loose flanges.
