焦炭塔的定期检验

Periodic Inspection of Coker Drum

焦炭塔的定期检验包括资料审查、宏观检验、超声波测厚、超声检测、磁粉检测、渗透检测、材料光谱分析、硬度检测、金相分析等。以某焦炭塔定期检验为例,叙述了主要检验步骤以及检验的重点和方法,针对检验中发现的问题,分析了腐蚀、鼓胀等产生的原因,提出了设计、制造及返修方面的要求以及预防措施。

The periodic inspection of the coke tower includes data review, macro inspection, ultrasonic thickness measurement, ultrasonic testing, magnetic particle testing, penetration testing, material spectrum analysis, hardness testing, metallographic analysis and so on. Taking coke tower periodic inspection as an example, We describe the main steps of the test, key parts and methods of inspection. Based on the problems found in inspection, we list the design, manufacturing and repair requirements, provide preventive measures and analyze the reasons of detects, such as corrosion and expansion.
