%X 球罐是一种在石油化工企业中广泛应用的压力容器，对在用球罐表面缺陷打磨处理后的凹坑尺寸评价直接影响设备能否安全运行。本文以某企业一台球罐为例，比较了《固定式压力容器安全技术监察规程》中无量纲参数法和《在用含缺陷压力容器安全评定》标准对凹坑允许尺寸的要求及相关参数影响规律，使用《在用含缺陷压力容器安全评定》标准能获得更大的凹坑允许尺寸参数范围，为凹坑缺陷安全性评价提供一定的参考。<br />
Spherical Storage Tank is a kind of pressure vessel widely used in petrochemical industry. The assessment result of the pits size after grinding the surface defects of the Spherical Storage Tank directly affects whether the equipment can be operated safely. Taking a Spherical Storage Tank in an enterprise as an example, this paper compares the difference in the allowable size of pits and the influence of relevant parameters in the two standards of Supervision Regulation on Safety Technology Stationary Pressure Vessel and Safety Assessment of In-Service Pressure Vessels Containing Defects. Using the standard of Safety Assessment of In-Service Pressure Vessels Containing Defects can obtain a larger range of allowable size parameters for pits. This paper can provide some references for the safety assessment of Spherical Storage Tank containing pits.
