DIN2655 PN25 Loose/Lapped Flange Standards, Dimensions & Weight

Our Company Manufacturer DIN Lapped Joint/Loose Flange refers to a specific type of lapped joint flange that is manufactured according to the DIN standards. The main characteristic of DIN Lapped Joint Flanges is their ability to rotate and move axially. The flange itself is not welded to the pipe or stub end, but instead, is free to rotate and move. This design allows for easy alignment of the bolt holes during assembly, and also allows for the removal of the stub end or pipe end without having to disassemble the entire flange connection.DIN Lapped Joint Flanges are commonly used in low-pressure applications and in systems where frequent disassembly is required. They are ideal for use in applications such as water supply systems, drainage systems, and irrigation systems.
