Performance characteristics:
The AF-2 type flange loose sleeve compensation joint with short pipe is formed by adding a short pipe flange on the basis of the flange loose sleeve compensation joint. The connection method is changed to flange connection at both ends. It is mainly used to connect pipeline valves and water meters. In water supply pipelines, especially for water supply pipelines with larger diameters, when installing valves or water meters, pipeline expanders must be installed to facilitate installation and disassembly. At the same time, it can compensate the axial displacement of the pipeline and thereby protect the valve and other equipment.
Main performance parameters:
