1.绪言 由于压力容器内的介质压力是最重要的设计条件,因此制造压力容器最适宜用高强度钢。 在压力容器中,球形容器具有同一容积下表面积最小及在同一内压下壁厚度最小等特点,因此适合于运用在大容量和高压的情况。所以球形容器大部分做为大容量的储罐和高压容器使用。 1. INTRODUCTION Since medium pressure in pressure vessels is the most important design condition, pressure vessels are most suitable for use with high strength steels. In the pressure vessel, the spherical vessel has the same surface area of ​​the smallest volume under the same pressure and the minimum wall thickness and other characteristics, it is suitable for use in the case of large capacity and high pressure. Therefore, the majority of spherical containers as high-capacity storage tanks and high pressure vessels.
