API Std 650 stainless and carbon steel tank definitions

BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API Std 650 stainless and carbon steel tank oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.

Proper use of API Std 650 stainless and carbon steel tank and precautions:
1. The API Std 650 stainless and carbon steel tank must be used within the safe height range;
2. Check before use to ensure that the safety valve and breathing valve are flexible and easy to use;
3. The explosion-proof and fire-proof safety measures for oil tanks are implemented effectively;
4. The oil level in the API Std 650 stainless and carbon steel tank should be accurately measured when receiving and delivering oil, so as to prevent overflow or empty;
5. In the process of receiving and sending oil, the flow rate of oil should be controlled, and it should not be too fast to avoid electrostatic accidents.

API Std 650 stainless and carbon steel tank Visual InspectionUpon completion of all the foregoing tests, the pressure in the tank shall be released and a thorough visual inspection shall be made of both the inside and outside of the tank, giving particular attention to all internal ties, braces, trusses, and their attachments to the walls of the tank. Anchors shall be checked for snug tightness and adjusted if required. Anchor threads shall be fouled by peening or tack welding to prevent loosening. In lieu of thread fouling, double nuts may be used.Rate of Water Filling and Water TemperatureThe rate at which water is introduced into a tank for a hydrostatic test shall not exceed 3 ft of depth per hour. The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.
