API 650 liquid-storage tanks workmanship
Thickness as it Affects Preheat and Post-heat RequirementsPlate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the API 650 liquid-storage tanks used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.
API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API 650 liquid-storage tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API 650 liquid-storage tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.
We have lots of successful cases, for example in July 2015, we exported 5714 tons ASTM A36 mild steel plate to Peru. After receiving the plates and putting then into use, our customer spoke highly of the ASTM A36 mild steel plate quality. In addition, the customer also introduced us an Venezuela customer, who bought 933 tons A36 steel API 650 liquid-storage tanks plate from us. And then in Mar. 2016, due to the first cooperation in July 2015 is very successful. The customer is very satisfied with our product quality and comprehensive service. This time, the customer place an 3989 tons order directly.
}Prefabrication requirements of API 650 liquid-storage tanks, large vertical storage tank wall panels:1. The prefabrication of wall panel shall be processed in strict accordance with the requirements of the drawings, and inspection records shall be made.2. After the wall panel is rolled, it should be placed on the platform for inspection with a template. In the vertical direction, use a straight-line template to check, the gap should not be greater than 2 mm, and in the horizontal direction, use an arc-shaped template to check, and the interval should not be greater than 4 mm.3. When wall panels are rounded, attention should be paid to prevent irreversible plastic deformation caused by external forces. After rolling, it should be placed on the platform for inspection, and then placed on the prepared mold.
