AF disassembly joint

AF type flange type loose sleeve expansion joint can absorb the axial displacement of the pipeline caused by thermal expansion and contraction, but cannot withstand axial pressure thrust. It is suitable for pipe connections with pipe diameters below DN800 in urban pipe network systems. It can be laid in the open, buried or in trenches, but it should not be directly buried in the wall or concrete. The flange connection should be equipped with an inspection room when it is installed concealed.
