A loose flange refers to a flange loosely fitted on the flange of a container or pipeline. It is a loose flange. The flange can be made by flanging, direct turning out, or another welding ring. The advantage is that no additional torque is generated to the container or pipeline when the flange is deformed, and it is convenient to manufacture. It can be made of materials different from the container or pipeline, which is convenient for saving precious metals. The disadvantage is that the flange thickness is large. Suitable for occasions where the vessel or pipeline is lined with brittle materials and the pressure is not high.
Slip on pipe flanges actually slip over the pipe. These pipe flanges are typically machined with an inside diameter slightly larger than the outside diameter of the pipe. Slip on pipe flanges are secured to the pipe with a fillet weld at the top and the bottom of the slip on pipe flanges.
