从理论上推导了管道壁厚的计算公式,并应用第三强度理论对壁厚进行校核。并对国外工程中经常用到的油气集输管道与长输管道壁厚计算公式进行了对比。经比较发现,虽然公式形式上略有不同,但都可回归到理论的壁厚计算公式。
The calculation formula of pipe wall thickness is derived theoretically, and the third intensity theory is used to check the wall thickness. The calculation formulas of wall thickness of oil and gas pipelines and long distance pipe commonly used in foreign projects are also compared. The comparison shows that although the formulas are slightly different in form, they can be reverted to the theoretical wall thickness calculation formula.
