API Std 650 anchored liquid-storage tanks burnout panel

Preheat Treatment
Many laboratory tests have shown preheat treatment of carbon steel to 300°F-400°F to be the equivalent of the post-heat treatment at no less than 1100°F insofar as the physical properties of the weldment are concerned.40,41 Some tests have indicated a slight advantage of the post-heat treatment. Most of the tests have been made on plates 3/4 in. - 1 in. thick; results must be viewed with caution if preheating is applied appreciably beyond this thickness range. However, for all practical purposes, improvement resulting from preheating is sufficiently well established so that preheat should be considered for field fabrication of API 620 crude oil tank plates over 3/4-in. thick whenever toughness of the tank API Std 650 anchored liquid-storage tanks is highly desired and the thermal post-heat treatment is impractical.

API 650 storage tank stipulates that if the thickness of the lower wall panel obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 anchored liquid-storage tanks hydrostatic pressure test (both do not include the corrosion allowance).

Tunisia cutomer purchased around 1500 tons 304L,310S stainless steel plate from us and make tanks in August, 2017. The company was skilled in the design and manufacture of stainless steel tanks, API Std 650 anchored liquid-storage tanks processing systems and equipment for the food, dairy, beverage, chemical, pharmaceutical, biotechnology, and pure water industries. They also sent the inspection team come our company and visited our production line. After using our stainless steel plate, the customer was very satisfied with our products.

The foundation design of the API Std 650 anchored liquid-storage tanks should meet the requirements of foundation stability and deformation, that is, the API Std 650 anchored liquid-storage tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API Std 650 anchored liquid-storage tanks and cause distortion and deformation of the tank wall and bottom plate.

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.
