Compound axial expansion joint

        The compound axial corrugated expansion joint, also known as the axial compound pull rod corrugated expansion joint, compound pull rod corrugated expansion joint, and compound pull rod metal expansion joint, is a specialized compensation device provided to users with low fatigue frequency and high compensation demand. The compound rod corrugated compensator is composed of two or more corrugated pipes and rods connected to the middle pipeline, end plates, spherical and conical surfaces, gaskets and other structural components. It has the characteristics of reasonable structure, large compensation, good sealing, strong corrosion resistance, and long service life, and has been widely used in high support and overhead laying of steam heating pipelines.
