A516 Gr 65 plates API 650 cylindrical tanks

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API 650 cylindrical tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

Ultrasonic testing can find the internal defects of API 650 cylindrical 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 650 cylindrical tanks and so on metal oil tanks. The feature of this method is convenient and fast.

In addition to the requirements of API Standard 620 tank Appendix Q.8.1, the nameplate shall be attached to the tank at an accessible location if it is outside of any insulation or protective covering of the tank. The nameplate for the inner tank shall be located on the outer tank wall but shall refer to the inner tank. The nameplate, if any, for the outer tank of a double-wall tank shall be located adjacent to the nameplate or the inner tank and shall refer to the outer tank.

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality API 650 cylindrical tanks products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.
