STRESS ANALISYS OF HIGH PRESSURE STEAMLINES IN THERMALPOWER PLANTS

摘要

A reliable assessment of the condition and residual life of high pressure steam pipelines requires defining stress state, which will take into consideration not just the impact of internal pressure and temperature but the all applied loads.For that, usage of numerical methods for calculation and analisys of stress state is neccesary.This paper presents possibilities and disandvatages of finite elements methods in steam pipeline stress analysis, which is also shown in detail by an example of main steam pipeline of thermal unit TPP Nikola Tesla A1.
