| Abstract: | Some problems encountered in direct installation of common bellows type expansion joints for heating pipeline are analyzed, and the total solution scheme is proposed. The development of directly buried bellows type expansion joints is achieved by taking measures in terms of strengthening their own anticorrosion, waterproof sealing, expansion and contraction of PE outer protection pipe and so on. A good application result in the engineering is obtained. |
