浅析海洋石油立式储罐工程焊接质量监管

Analysis on Welding Quality Supervision of Vertical Storage Tank for Offshore Oilfield

储罐的焊接质量是石油储罐工程质量把控的关键,强化储罐焊接的质量监管,无疑是工程质量监督工作的重中之重。以中海炼化某原油罐区工程10×10~4m^3双盘浮顶油罐焊接质量监管为例,结合质量监督过程中发现的焊接质量问题,阐述了海洋石油立式储罐焊接质量控制的重点和难点,指出了把控焊接质量的监管措施和手段,为今后海洋石油大型立式储罐工程焊接质量保证提供了参考。

The welding quality of the storage tank is the key to the quality control of the oil tank project. Strengthening the supervision of the tank welding quality is undoubtedly the most important task of the project quality supervision. Taking the welding quality supervi- sion of the double deck floating roof tanks of 100 thousands m3 in a refinery factory of CNOOC as an example, the key points and diffi- culties in the welding quality control of the vertical tanks for offshore oilfield are expounded based on the welding quality problems found in the process of quality supervision, and the supervision and management measures of controlling welding quality are put forward, which provides reference for the welding quality assurance of large vertical storage tank project in offshore oilfield.
