Weld metal impact specimens shall be taken across the weld with the notch in the API 620 oil tank material weld metal. The specimen shall be oriented so that the notch is normal to the surface of the material. One face of the specimen shall be substantially parallel to and within 1/16 in. of the surface.In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API standard 650 larger diameter tanks external floating roof to open cylindrical steel API standard 650 larger diameter tanks tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.Enterprise Motto:Integrity, harmony, dedication, innovation and developmentAbility is the cornerstone of success; action is the ladder of successGrow with the enterprise; progress with the enterpriseGive a platform to those who actually do things and a stage to those who successfully do thingsDare to be the first, to pursue excellence.Prefabrication requirements for API standard 650 larger diameter tanks, large vertical storage tanks:
