The selection of z-section expansion joints is the same as that of l-section expansion joints. When pipeline deformation is allowed,
The angular expansion joint as shown in FIG. 4(a) or the transverse expansion joint as shown in FIG. 4(b) can be used when the pipeline deformation is not allowed.
The space for selecting three expansion joints in FIG. 3 (c, d and e) is respectively adopted

The selection of expansion joints in z-section is similar to that in plane z-section.
Simply change the two angular expansion joints to universal angular expansion joints, as shown in FIG. 5
