API Std 650 SUG III tanks roof columns

The opening pressure or vacuum of the pressure relief and API Std 650 SUG III tanks vacuum relief valves shall be checked by pumping air above the water level and releasing the pressure and then partially withdrawing water from the tank. After the tank has been emptied of water and is at atmospheric pressure, the anchorage, if provided, shall be rechecked for tightness against the hold-down brackets. Air pressure, equal to the design pressure, shall be applied to the empty tank, and the anchorage, if provided, and the foundation shall be checked for uplift.

This standard only applies to API 650 storage tanks API Std 650 SUG III tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).

In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 SUG III tanks. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API Std 650 SUG III tanks area to avoid lightning accidents. Observe the groundwater level of the API Std 650 SUG III tanks area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API Std 650 SUG III tanks from leaking and rusting due to untimely drainage.
