决定钢管管壁厚度的经验公式已应用了50多年,这些公式对于小尺寸钢管偏于保守,而对于大尺寸钢管则相反。可是,本文中导出的公式提供一个考虑目前通用的高强度钢的更精确和更经济的最小厚度的控制标准。
Empirical formulas that determine the wall thickness of steel pipes have been used for more than 50 years. These formulas are conservative for small-sized steel pipes and vice versa for large-sized steel pipes. However, the formulas derived in this article provide a control criterion that considers the more accurate and economical minimum thickness of currently popular high-strength steels.
