  pressure vessel design
Using pressure vessel design formulas, the weight of an Al sphere rated to 1200 psia with a safety factor of 2.5 would weigh 30 g.
      
The cylindrical shell is the most frequently used geometrical shape in pressure vessel design.
      
To put the comparison on a common denominator, we assumed the storage vessel was aluminum with a pressure vessel design using 2.5 for a safety factor.
      
Shell discontinuity analysis and the finite element method are discussed in relation to pressure vessel design by analysis in the following sections.
      
It was never intended to be, or marketed as an all-inclusive pressure vessel design program.

The present paper is concerned with limit analysis of thin cylindrical shell with hemispherical ends under internal pressure. Seven cases of collapse-mechanisms for various geometric parameters of shells are examined and the complete solutions for each mechanism are obtained. The conditions of validity for each mechanism are determined, and it is proved that the solution is exhausted by the seven cases considered. The results obtained are useful for pressure vessel design.

Since the accidents caused by the failure of high pressure vessels can be disastrous, the essential things in pressure vessel design is to ensure that the vessel designed is inherently safe, or say "leak before break". So the compound or wire-wounded pressure vessels are often adopted to assure the fail safe of thick-wall vessels. Furthermore, all the aspects, such as vessel design, material selection, and inspection must be strictly considered;In practice, the elastisity criterion had little effect to the failure of ultra high pressure vessels. However, the design guided by fracture mechanics criterion can predict the failure more accurately, and then the endurable fatigue life is substitued by the limited number of pressure cyclse. In view of large reduction in fracture toughness in the steel with extra highyield strength, the steel should be required to have both sufficient strength and ductility to avoid the cataelastic fracture of the vessel. Thus the lower limit of (KIc/σs) should be checked.Some discussion is also given of the routine safty inspection.

由于高压容器的事故是灾难性的,所以在设计压力容器时首要的是使容器具有安全失效或称为“裂前先漏”的性质。因此常采用复合式或绕丝式的容器,使厚壁容器具有安全失效的性能。此外,对容器的设计、选材及检查均须作细致的要求。 实践表明,按弹性理论设计已不适用于作超高压容器失效的判据,而用断裂力学原则设计却显示与实际结果一致。通常在计算中,以容器的低周疲劳寿命代替原持久寿命。 鉴于容器的屈服强度过高会导致材料断裂韧性大幅度地降低,故容器用钢应具备有充分的韧性和强度综合性能,为此,须检查材料的(K_(IC)/σ_s)~2的下限值。 文中对于定期检查以确保安全的问题,也作了论述。

Na_2SnF_6 hydrolysis reaction was investigated previously by using Morey pressure vessel (Wang et al., 1965). In the present study, the same experiments have been conducted by using the other three different pressure vessels: rapid quenching cold-seal pressure vessel (designed by Hemley J. J.), roking vessel with a golden bag (Dickson-type improved by Hemley, J. J.), and tuttle type routine cold-seal vessel at 200—647℃ and 1 kbar. The experimental results...

Na_2SnF_6 hydrolysis reaction was investigated previously by using Morey pressure vessel (Wang et al., 1965). In the present study, the same experiments have been conducted by using the other three different pressure vessels: rapid quenching cold-seal pressure vessel (designed by Hemley J. J.), roking vessel with a golden bag (Dickson-type improved by Hemley, J. J.), and tuttle type routine cold-seal vessel at 200—647℃ and 1 kbar. The experimental results obtained are compared, suggesting that quenching rates would affect the precision of experimental results, especially over 400℃. The rapid quenching vessel and the rocking vessel with a golden bag are ideal apparatuses for chemical equilibrium reactions of this kind. The use of the hydrolysis method described allows one to work out the constant for hydrolysis reaction and the corresponding enthalpy.

用四种不同类型高压釜研究Na_2SnF_6在200—647℃、1 kbar条件下的水解特征。实验表明,淬火速率影响实验结果的精度。快速淬火高压釜及金袋摇摆釜是研究这类化学平衡反应的理想设备,采用水解法可获得水解常数及热焓。
