API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at api 620 tank design pressure design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.

Upon completion of construction, provide Purchaser with copies of Field Erected api 620 tank design pressure Storage Tank Datasheets in accordance with Appendix L of API 650, which reflects the as-built conditions, certifying that the tank conforms with the requirements of this specification.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.

The cone slope of the completed api 620 tank design pressure foundation is 15/1000 for the general foundation and less than 35/1000 for the soft foundation. After the foundation settlement of the storage tank is basically stable, the surface slope must be greater than eight thousandths. The edge of the tank bottom should be more than 0.3 meters higher than the surrounding ground. Above the ground, the tank bottom leakage detection tube should be drawn from the foundation sand cushion and cross the foundation ring wall or the slope protection surface. The circumferential distance should be less than 20 meters, and each api 620 tank design pressure should have at least 4 detection tubes.
