API Std 650 closed top welded storage tanks liquid-mounted seals

Ultrasonic testing can find the internal defects of API Std 650 closed top welded storage tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API Std 650 closed top welded storage tanks and so on metal oil tanks. The feature of this method is convenient and fast.

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.

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 closed top welded storage tanks tank wall thickness is not considered in the tank wall design.
