API 650 ground supported flat-bottom tanks roof columns

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 ground supported flat-bottom tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.

Usually, the wind load in the API 650 ground supported flat-bottom tanks construction area should be considered before the tank design and construction. The wind load in the API 650 ground supported flat-bottom tanks construction area has an impact on the stability and economy of the API 650 ground supported flat-bottom tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API 650 ground supported flat-bottom tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

Temperature Range: The provisions in this appendix are considered suitable for API 650 ground supported flat-bottom tanks design metal temperatures from + 40°F to –60°F, inclusive. In general, refrigerated tank primary components include those components whose failure would result in leakage of the liquid being stored, those exposed to the refrigerated temperature, and those subject to thermal shock. Further definitions of such components are provided in API Standard 620 tank R.1.4.2 and R.1.4.3.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

In the process of API 650 ground supported flat-bottom tanks steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API 650 ground supported flat-bottom tanks different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
