Advance Tank provides our customers with field erected tanks built in strict accordance with the American Petroleum Institute’s (API) standards. As an API member, we are up-to-date on the latest news, policies, and design requirements. Advance Tank provides custom design, fabrication and erection of tanks that meet API standards and customer specific requirements. With in-house engineering, experienced drafters, complete fabrication capabilities and field crews located throughout the country, we will be there when you need us.

AMETank is the NEXT GENERATION of Aboveground Storage Tank DESIGN, DRAFTING, & RE-RATING Software. Partnering with Technosoft, we have released AMETank which combines ETank2000's engineering & design capabilities with Technosofts state of the art 3D Modeling, Estimating, &. Listed in section 4, subject to the modifications and limitations indicated in API 650 standard. Material produced to specifications other than those listed in this section may be employed, provided that the material is certified to meet all of the requirements of an applicable material specification listed in API650. Virtual hidden in plain sight. If the example shown in the link is meant to represent API 650, you may want to note that the hole diameter 'dp' in the tank shell should be between 11 1/4' and 11 1/2' ( both per API 650 ) and possibly use 11 1/2' ( you have used 11' ) to show the most conservative calculations.


API 650 is the standard governing welded tanks for oil storage. It dictates tank design, fabrication, welding, inspection, and erection requirements. API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil, gasoline, chemicals and produced water. Advance Tank has extensive experience with API 650 tanks ranging in diameter from 8' - 300' for refineries, terminals, pipeline facilities and other clients.

API 620 governs the design and construction of large, welded, low pressure storage tanks. These storage tanks operate at 250°F or less with an operating pressure of up to 15 PSI. API 620 Tanks are generally utilized for Liquefied Natural Gas (LNG) storage as well as other chemicals which require internal design pressures in excess of those allowed by API 650.


The API 12D specification is utilized in the fabrication and erection of field welded tanks for storage of production liquids. In general, this standard is commonly used by upstream petrochemical companies. The API 12D standard is to field erected tanks as API 12F is to shop built tanks. API 12D predetermines tank dimensions, design pressure and vacuums, with accessories and testing requirements. This eliminates the need for further engineering, effectively reducing the cost of each tank.
