A662 grade B plates API Std 650 fixed roof tanks

API 650 petroleum storage tank pipeline stress and product pressure, tank pressure, uniform or non-uniform temperature difference between the tank wall and the tank bottom, which cause the radial displacement and longitudinal rotation of the API Std 650 Fixed roof tanks tank wall at the opening to affect the oil tank wall The impact is obvious. Therefore, the design must ensure that the load applied by the external pipeline on the opening of the tank wall is within the safety limit. If the stress of the API Std 650 fixed roof tanks connecting piping is not handled properly, the wall of the API 650 petroleum storage tank may deform or even rupture, causing a major accident.

Our company will accept the product quality objection registration record, pass it to the API Std 650 fixed roof tanks production unit and relevant departments, and timely coordinate the supervision of product API Std 650 fixed roof tanks quality objection.

Roof nozzles in contact with the refrigerated liquid shall be considered primary components.

The safety inspection of atmospheric storage tank, API Std 650 fixed roof tanks is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API Std 650 fixed roof tanks requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.
