Construction of under-bottom connections for API 650 horizontal tank

API 650 internal floating roof API 650 horizontal tank tank can be used to store gasoline, jet fuel and other volatile oil products, as well as aldehydes, alcohols (methanol, ethanol), ketones (acetone), benzene (benzene, toluene, xylene, styrene) and other liquid chemicals.

To scientifically evaluate the remaining service life of the API 650 horizontal tank, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API 650 horizontal tank, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 650 horizontal tank are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

The opening pressure or vacuum of the pressure relief and API 650 horizontal tank 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.

Our team is a dynamic, but also mature and steady team. The talents are made of different ages. There are experienced ones, and also creative ones, that also makes our company culture diversified.
