Abstract

A calculation of welded pressure vessels for fire safety is shown in this paper. At the first step, the temperature of the steel walls has been investigated, and the inner liquid pressure and the temperature increase. It is assumed that the safety valve is out of work and cannot reduce the increasing pressure. At the second step, the growing pressure and softening steel represent danger after a critical time. The result will be a safe time when the damage will occur. Three different alternatives have been calculated: the increase of the vessel wall thickness, the increase of the applied steel yield stress, the effect of the thermal coating. The thermal coating was the best alternative. This kind of calculation helps to find the best safe solution.

压力容器的防火安全设计

本文给出了焊接压力容器的防火安全计算方法。在第一步，研究了钢壁的温度，以及内部液体压力和温度的升高。假定安全阀不工作，不能降低不断增加的压力。在第二步中，压力的增加和钢的软化代表了临界时间后的危险。结果将是一个安全的时间，当损坏将发生。计算了三种不同的替代方案:增加容器壁厚，增加钢的屈服应力，热涂层的影响。热涂层是最好的选择。这种计算有助于找到最安全的解决方案。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
