| Abstract: | The design methods,pipeline arrangement forms,construction difficulties and operation maintenance between directly buried cold installation without expansion joint and directly buried installation with expansion joint are compared.The design results and economy of the two installation methods are also compared with an engineering example.The design method of directly buried cold installation without expansion joint is more complicated than that of directly buried installation with expansion joint.The pipeline arrangement form,construction difficulty,operation maintenance and economy of the former are better than that of the latter. |
