Verification and analyzing the safety of heating pipeline in river crossing project

The safety of heating pipeline stress is a key issue in the heating pipe networks.Taking the immersed pipe crossing the Haihe River project of Huadian Tianjin Junliangcheng Power Generation Company Limited and Tianjin Chentangzhuang Thermal Power Company Limited as the example,the deflection,shear stress and bending stress of the metal pipes are checked.In order to solve the problem of deflection overrun,measures to bundle the float ball and add intermediate support points have been adopted to provide reference for the construction of the river crossing pipeline.
