API standard 650 cylindrical liquid-storage tank water drawoff sumps

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API standard 650 cylindrical liquid-storage tank may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.

The outer FRP of API 650 oil tank will not produce electrolytic corrosion with groundwater and brine. The outer FRP will not corrode with gasoline, diesel oil and leaded gasoline API standard 650 cylindrical liquid-storage tank. The leakage detector can monitor the whole process 24 hours to eliminate the potential pollution. The leakage detection system is convenient for the inspection and maintenance of API 650 oil tank, and protects the original ecological environment of soil and groundwater.

LSAW Pipe to Peru. In the beginning of 2014, Peru government released an international tender for one of the hydroelectric power plant. Finally they chose us as the contractor, we purchased the steel plate and then fabricate the API standard 650 cylindrical liquid-storage tank steel plate into steel pipe, and then make the corrosion protect on the surface, we also supply the fitting with our steel plate, the total value of this order is about 2 million USD.

The water dissolved in the oil will be separated out from the oil stored in the API standard 650 cylindrical liquid-storage tank for a long time, and the acidic water layer will appear at the bottom of the API standard 650 cylindrical liquid-storage tank for a long time, which will accelerate the corrosion of the API standard 650 cylindrical liquid-storage tank and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 cylindrical liquid-storage tank must be inspected and cleaned regularly to check the hidden danger.

Our quality and service commitment: API standard 650 cylindrical liquid-storage tank product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
