Steel pipe materials for API standard 650 mechanically-anchored tanks

API Standard 620 tank Appendix C describes the factors involved in obtaining adequate foundations for tanks that operate at atmospheric temperature. The foundations for refrigerated tanks are complicated because of the thermal movement of the tank, the insulation required for the bottom, the effects of foundation freezing and possible frost heaving, and the anchorage required to resist uplift. The services of a qualified foundation engineer are essential. Experience with tanks in the area may provide sufficient data, but normally a thorough investigation, including soil tests, would be required for proper design of the foundation.For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API standard 650 mechanically-anchored tanks Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.On August 29th Clients from Senegal visited us-Zhengzhou office and wanted to know more about BBN to build a long relationship.
