Mechanical loads on API Std 650 duplex stainless steel tanks
This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API Std 650 duplex stainless steel tanks storage of petroleum, petroleum products. and other liquid products.
The longer the service life of the API Std 650 duplex stainless steel tanks, the lower the reliability and the prone to failure. Doing a good job in the maintenance of the metal oil tank can ensure the normal use of the oil tank, reduce the wear of the API Std 650 duplex stainless steel tanks body and accessories, and extend the service life of the oil tank. The maintenance of metal oil tanks is mainly to do a good job in the anti-corrosion of the oil tank, the cleaning of the deposits in the API Std 650 duplex stainless steel tanks and the overhaul of its accessories. Regularly inspect and maintain the accessories of the oil tank: valves, oil measuring holes, breathing valves, flame arresters, ladders, foam fire extinguishing generators, etc., and make records. If any damage is found, repair them in time.
Standard Hydrostatic and Pneumatic TestsAfter erection is completed and stress relieving, radiographic examinations, or other similar operations, as may be required, are performed, each tank shall satisfactorily pass a series of hydrostatic and pneumatic tests as prescribed in 7.18.2 through 7.18.6. Whenever a solution film is specified in this section to be applied to welding, linseed oil or another equivalent material for disclosing air leakage may be substituted. In freezing weather, linseed oil or a similarly suitable material shall be used.The attachment welding around all openings and their reinforcements in the walls of the API 620 tank shall be examined by the magnetic-particle method both inside and outside the tank API Std 650 duplex stainless steel tanks. When the underside of a tank bottom rests directly on the tank grade (and is not accessible after erection), such examination of welding on the underside of the bottom and subsequent air testing may be omitted.
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 Std 650 duplex stainless steel 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.
