目前,球形容器在石油、化工、冶金、城建等部门得到了比较广泛的应用。由于种种原因发生了几起严重事故,造成了严重损失。因此,提高球形容器的建造质量、确保球形容器的安全运行,已成为十分迫切的问题。液化气球罐的建造要经过设计、选材、压片、现场组装焊接、整体热处理、水压试验等很多工序;在使用中,液化气球罐壳体还要长期接触含有 H_2S 的介质。因此,液化气球罐的安全性与很多因素有关。本文仅就与液化石油气球形容器(以下简称液化气球罐)的安全性有关的一些问题进行分析。一、液化气球罐壳体常用钢材焊接裂纹分析推荐的液化气球罐壳体用钢有 A3F、16MnR、
At present, spherical containers in the petroleum, chemical, metallurgy, urban construction and other departments have been more widely used. Due to various reasons, several serious accidents occurred, causing serious losses. Therefore, to improve the construction quality of spherical containers and to ensure the safe operation of spherical containers has become a very urgent issue. The construction of liquefied gas balloon tank is governed by many processes such as design, material selection, tabletting, site assembly welding, overall heat treatment and hydrostatic test. In use, the shell of liquefied gas balloon tank needs long-term contact with the medium containing H2S. Therefore, the safety of liquefied gas balloon tank and many factors. This article only on the liquefied petroleum gas spherical container (hereinafter referred to as the liquefied gas balloon) some of the issues related to the safety analysis. First, the liquefied gas tank shells commonly used steel welding crack analysis Recommended liquefied gas tank shell steel A3F, 16MnR,
