A mathematical model is presented, and numerical experiments are performed to describe the mechanics of the slow movement of a pipeline. The problem reduction algorithm to one-dimensional formulation is offered. Results of numerical experiment for the model problem are adduced. The proposed mathematical model is found to adequately describe the dynamics of known phenomena of pipes. The cross-sections of the extended curvilinear thin-walled pipeline are numerically demonstrated to experience warping, which has experimental confirmation in the literature.

The paper discusses the structural design of a futuristic 700℃ MS(Molten salt)Storage shell,which considers many elements in providing an adequate and comprehensive *** designing the structural carbon steel for the tank,temperature is an important consideration because steel has a yield strength at 700℃,that is 33%of its nominal yield,while the Young’s Modulus at 700℃ is 50%of its nominal Young’s *** this temperature,thermal stresses can yield or tear the structural steel unless free expansion of the structure is *** is accomplished with sand layers below each layer of steel and by including a small gap behind the side carbon steel layer.A roof shell design for the tank is also presented in this paper,comparing various roof shell types and their *** designs include thermal insulation and an inner stainless steel corrosion layer to protect the structural and thermal insulation elements of the tank from the MS.
