A524 grade I pipe API Std 650 mixed material tanks

API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at API Std 650 mixed material tanks design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.

When API 650 storage tank is designed, when the design pressure is small F2 kPa, the impact of air pressure on the API Std 650 mixed material tanks tank wall thickness is not considered in the tank wall design.

In year 2015, we supplied 950 tons S355J0 angle steel to Egypt government. We have cooperation with local government for more than 3 years. Every year, they would order more than 3000 tons of API Std 650 mixed material tanks steel from our company.

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 mixed material 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 mixed material tanks area to avoid lightning accidents. Observe the groundwater level of the API Std 650 mixed material 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 mixed material tanks from leaking and rusting due to untimely drainage.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API Std 650 mixed material tanks plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
