| 摘 要： | 通过实例阐述了北主油库防冻害的重要性，并对如何防冻害问题提出了三点意见。（１）选用附件时要考虑防冻问题，在油罐前及管道转换环节处，应选用寿命长，可靠性高的阀门，且安装前要重新打压试验，油罐呼吸阀应多装１个，以减少油罐被吸瘪事故的发生；防腐处理建议采用有机涂料和牺牲阳极联合防护法进行防护。（２）施工中要加焊缝的检验。焊缝的内部裂纹，夹渣，未焊透等内伤，不能简单地采用外观检查、煤油试、真空试漏等方法，

| Abstract: | Due to the cold weather in winter seasons in the northern areas, oil spitting is often the case on tank farms. Freezing damage control is considered important through reading the example given. Three suggestions are set forth on how to control freezing damage: (1 )Anti freezing should be put into account during additional part selection. Valves to be installed before the tanks and at the positions where pipeline will turn should be reliable and of long service life, further more, they should be pressure tested again before installation ( to have one more tank breathing valve so as to avoid the accident that the tank is breathed empty; orgaism coating material and sacrifice anode protection are recommened for corrosion control. (2) Strenthening the inspection of welding rods during construction. For the welds, internal cracks, inclusion, unpenetration and other internal damages should not be simply examined by visual inspection , using kerosene to define filtration, vacume method to define leakage, instead of ultrasonic detection should be adopted. (3) Protection measure should be taken timely, for example, before winter comes,such inspections should be performed to see if the foundation of an oil tank settles or not, if there is any tendeacy of tank body tilting, any water collected near the bottom, venting valve working condition etc. For pipelines. to be inspected are the pipe supports, telescope device, if the slope is in the conformity with the designed one, if the depth of corer can meet the requirements, any water. debris and oily dirt etc. |
