Do you know what occasions loose flanges are generally used in?

Loose flange: This kind of flange is often used in the case where the medium temperature and pressure are not high and the medium nozzle is highly corrosive. The loose flange is generally used in combination with the flanging short joint, that is, the flange ring is loosely sleeved outside the flanging short joint, the pipe is butt welded with the flanging short joint, and the flange sealing surface is processed on the flanging short joint.

In addition, there are flat welding ring and butt welding ring plate loose flange. Since the flange itself is not in contact with the medium, only the flanging pup joint or the welding ring is required to be consistent with the pipe material, and the material of the flange body can be completely different from the pipe material, so it is especially suitable for corrosive medium pipelines, which can save stainless steel and non-ferrous metals. and other valuable corrosion-resistant materials. On the water supply and drainage fittings, such as expansion joints, the most common ones, when the manufacturer leaves the factory, there are loose flanges at both ends of the expansion joints, which are directly connected with the pipelines and equipment in the project with bolts.

However, it also has disadvantages

weakness is:

1. Low pressure.

2. The strength of the welding ring is low (especially when the thickness is below 3mm)
