Prnduct introduction: External pressure axial expansion joint is composed of inner cylinder, bellows. outer cylinder and auxiliary components. The bellows is subjected to external p1·essure, has good sealing and bending resistance. and can absorb large displacements. Can be made into single, double, two-way and other forms. The external pressure axial co1-rugated expansion joint mainly absorbs the axial displacement. and has the advantages of large compensation amount, good thermal insulation performance, and residual medium can be eliminated.
