Novel composite carbon steel floating plate and preparation method thereof

Abstract

The invention discloses a novel composite carbon steel floating plate and a preparation method thereof. After a conventional carbon steel floating plate is manufactured in a floating roof oil tank, the immersion part of the carbon steel floating plate is constructed, the inner wall of a through hole is sequentially coated with and / or paved with a special primer layer A and a prepreg layer of light-cured glass steel materials from inside to outside, the tail end of the through hole and the surface layer of a bottom plate are adhered with an annular reinforcing ring, and the inner circle of thereinforcing ring is right opposite to the inner diameter of the through hole; and the side wall and the bottom plate are sequentially coated and / or paved with a special primer layer B, a prepreg layerof a first layer of light-cured glass fiber reinforced plastic materials , a prepreg layer of a second layer of light-cured glass fiber reinforced plastic materials and a conducting layer from insideto outside. According to the novel composite carbon steel floating plate and the preparation method thereof, a glass fiber reinforced plastic reinforcement layer is constructed on the lower surface of the carbon steel floating plate, so that the service life of the carbon steel floating plate can be greatly prolonged, and the running safety of the floating plate is improved; and by adopting the novel light-cured glass fiber reinforced plastic prepreg construction process as the glass fiber reinforced plastic main body of the composite floating plate, the construction speed can be greatly improved, and the construction difficulty is reduced.

Description

technical field [0001] The invention relates to a novel composite carbon steel floating disc and a preparation method thereof. Background technique [0002] With the increasing scale of oil storage tanks and oil depots, the requirements for floating trays of floating roof oil storage tanks are getting higher and higher. In recent years, there have been many accidents of floating roof storage tanks being struck by lightning, and the most serious one is the explosion accident of internal floating roof storage tanks. Many of these accidents of internal floating roof storage tanks are caused by the poor sealing of the floating plate and the internal memory of the storage tank. In explosive gas, the concentration of oil and gas near the exhaust port of the storage tank is caused by excessive concentration. At the same time, the loose sealing of the floating plate also causes a large amount of hydrocarbon gas to volatilize, causing serious environmental pollution and seriously af...

Problems solved by technology

[0004] This is mainly because the origin of crude oil is different, and the components and impurities contained in crude oil are also different. Crude oil contains a large number of ions and molecules that affect corrosion, including CL-, HCO3, SO4, H2S, CO2, etc. These ions or molecules can be combined with The iron undergoes electrochemical reactions, and due to the frequent operation of the hand valve, the erosion of the sand and stones contained in the incoming oil on the bottom of the floating plate will cause damage to the anti-corrosion layer, and at the same time aggravate the occurrence of corrosion, and the floating plate cannot use measures such as anode protection , can only rely on anti-corrosion, once the anti-corrosion layer is damaged, it will soon produce more serious corrosion
