The finite element method is used to analyze the pipeline system. The calculation method of the pipeline cold storage pad is calculated by manual method, and the accuracy of the calculation result is low. This is also the reason why the actual parameters and design of the early pipeline support and hanger are quite different. One of the current calculation methods for cold storage blocks is based on the finite element method. The finite element method is used to analyze the pipeline system, and the displacement, internal force and internal moment and stress of the pipeline under internal pressure, self-weight, concentrated force, temperature change, cold tightness and wind load, seismic load, etc. can be calculated, and The B31 procedure performs strength checks. The software package considers the type of support and hanger of the pipeline comprehensively, and fully considers various welding forms, stress enhancement factors, flexible systems and corrosion of pipelines.
The purpose of the calculation of pipeline stress calculation by the design department is to design the support hanger arrangement and load according to certain strength conditions. The calculation method is to first determine the pipeline orientation and the position of the support and hanger according to the design rules, and the calculation program is based on the pipeline support point. The thermal displacement and load at the location determine the type and parameters of the hanger and hanger, and the design and installation drawings of each hanger are proposed. This calculation considers the weight of the pipe and the components of the hanger and the weight of the insulation, etc., based on theoretical values, and the errors that may occur during the installation process cannot be considered. The load and thermal displacement of the actual support and hanger may not match the calculated values. On the contrary, the calculations we carry out are based on the actual state of the pipelines and the hangers. The calculations are based on the actual layout of the pipelines, the actual weight of the pipelines and insulation, and the actual loads of the hangers. Only the strength of the pipelines and hangers is required. Meet the requirements, regardless of whether it is consistent with the original design value, thereby ensuring that the stress of the pipeline is at a reasonable level. Extending the life of the pipe can reduce the workload of adjusting the hangers. Tongda Company reminds you to calculate the correct use of cold storage mats.
