API 650 partially anchored liquid-storage tanks designed and constructed for elevated temperature service

Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API 650 partially anchored liquid-storage tanks External floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API 650 partially anchored liquid-storage tanks external floating roof tank.

Usually, the wind load in the API 650 partially anchored liquid-storage tanks construction area should be considered before the tank design and construction. The wind load in the API 650 partially anchored liquid-storage tanks construction area has an impact on the stability and economy of the API 650 partially anchored liquid-storage tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API 650 partially anchored liquid-storage tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

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 650 partially anchored liquid-storage tanks is highly desired and the thermal post-heat treatment is impractical.

Our team is a dynamic, but also mature and steady team. The talents are made of different ages. There are experienced ones, and also creative ones, that also makes our company culture diversified. We have complete department structure, to make the whole work procedure run smoothly. For every step, we have special person to be in charge and responsible for our customer and update information to the customer in time. So you just need not worry too much to purchase steel materials from our company.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API 650 partially anchored liquid-storage tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
