油罐基础沥青砂防腐层是金属油罐的承载接触面,也是保护油罐底板不发生电化学腐蚀、阻隔砂垫层毛细水上升的重要措施。在建罐过程中,它为油罐提供了一个坚实的初始表面和标准的水平参照面。油罐基础如果出现沥青砂防腐层表面平整度的缺陷和误差,会造成罐体垂直偏差超标,影响浮盘升降和物料计量,甚至使油罐底板提早失效,从而减少油罐的使用寿命,影响储油安全。本文介绍通过QC活动提高油罐基础沥青砂防腐层施工质量的措施。
Tank foundation tar sand anticorrosion coating is the bearing surface of the metal tank, but also to protect the tank bottom electrochemical corrosion does not occur, blocking the capillary layer of water is an important measure to rise. During tank construction, it provides a solid initial surface and standard horizontal reference surface for the tank. If the tank foundation defects and errors of surface roughness of asphalt sand anti-corrosion coating, will cause the tank vertical deviation exceeds the standard, affect the float lift and material measurement, or even early failure of the tank bottom, thereby reducing the life of the tank, the impact Oil storage safety. This article describes how to improve the construction quality of oil tarmac base tar sand by QC activities.
