GB150—1998近似椭圆封头厚度设计商榷

Discussion on thickness design of approximate ellipsoidal head in GB 150—1998

对ＧＢ１５０ —１９９８ 中近似椭圆封头厚度设计公式提出了不同看法，从国内外有关标准以及制造检验方面进行讨论，认为设计标准椭圆封头时应采用与其它相关标准相同的设计公式。

The controversial issues on the thickness design of approximate ellipsoidal head in GB 150—1998 were discussed with respect to the procedures of manufacture and examination specified in both domestic and abroad standards.The same design formula should be used for thickness calculation of approximate ellipsoidal heads and standard ellipsoidal heads.
