API Std 650 open-top tanks rectangular roof openings

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 API Std 650 open-top tanks 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.

Proof Tests for Establishing Allowable Working PressuresBecause pressures in liquid storage tanks built according to these rules vary quite markedly from the tops to the bottoms of the tanks, proof testing of these tanks presents problems not usually encountered in the construction of unfired pressure vessels–especially where the API Std 650 open-top tanks parts under investigation are located near the bottoms of the tanks. The principal difficulty is devising a test or series of tests that will reliably establish the working pressure that can be permitted on the part of the unproven design without, at the same time, imposing hazardous conditions on other parts located at higher levels in the tank.
