At the same time, the two near-end faces are connected by at least one set of angle steel flanges 3 and several sets of bolted pipe joint end flanges. Among them, the adjacent second sides 32 of each group of angle steel flanges 3 are connected to each other, specifically, they can be connected by axial bolts 7, and the number of axial bolts 7 can be set according to the diameter of the pipe. , A plurality of axial bolts 7 can be provided, and if the pipe diameter is small, the number of axial bolts 7 can be appropriately reduced.
