ISO 630 Gr E355D plates API 650 floating-roof tanks

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 floating-roof tanks is highly desired and the thermal post-heat treatment is impractical.

API 650 internal floating roof API 650 floating-roof tanks tank can be used to store gasoline, jet fuel and other volatile oil products, as well as aldehydes, alcohols (methanol, ethanol), ketones (acetone), benzene (benzene, toluene, xylene, styrene) and other liquid chemicals.

"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and API 650 floating-roof tanks product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."

Usually, the wind load in the API 650 floating-roof tanks construction area should be considered before the tank design and construction. The wind load in the API 650 floating-roof tanks construction area has an impact on the stability and economy of the API 650 floating-roof 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 floating-roof tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

Our quality and service commitment: API 650 floating-roof tanks product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
