Embodiment Construction

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] A method for transforming a single-layer oil tank into a double-layer oil tank, comprising the steps of:

[0038] S1. Inner wall derusting

[0039] Degrease and sandblast the inner wall of the single-layer steel oil tank buried in service to expose the metal light and reach Sa2.5 level; pre-treat the inner corners of the tank and fill them with resin putty to make the edges A smooth transition is formed at the corner; after the tank is cleaned, in order to utilize the remaining strength of the original...

Abstract

The invention relates to a method for improving a single-layer oil tank into a double-layer oil tank. On the basis that the inner wall of the buried single-layer steel oil tank in service is derusted, an anti-corrosion reinforcing coating, a 3D through gap layer and a glass steel inner tank are sequentially manufactured, and the single-layer oil tank is quickly improved into the glass steel double-layer oil tank with a through gap layer space. The 3D through gap layer is communicated with a tank top monitoring well, and sealing performance of the inner tank and the steel outer tank in service can be monitored all day long. The inner surface of the glass steel inner tank is coated with an anti-static layer which makes direct contact with stored liquid, the anti-static layer is connected with an original steel storage tank, and the original steel single-layer storage tank is grounded so that electrostatic hazards can be avoided. The inner tank is made from a glass steel material formed by mixing resin and glass fiber. The oil tank improvement method has the advantages of being good in safety, high in strength, convenient to manufacture and the like, corrosion resistance of the oil tank is improved, the overhaul frequency is reduced, the service life is prolonged, and improvement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of buried oil tanks for gas stations, in particular to a method for transforming a single-layer oil tank into a double-layer oil tank. Background technique [0002] With the vigorous development of my country's automobile industry and transportation industry, more and more gas stations have emerged as the times require. According to relevant data, there are currently more than 100,000 gas stations in my country. According to my country's current national standard GB50156-2012 "Code for Design and Construction of Automobile Gas Stations" (2014 Edition), the gasoline and diesel storage tanks of automobile gas stations should be horizontal tanks and buried underground. At present, my country's automobile gas stations generally use single-layer steel horizontal buried oil tanks. This kind of oil tank is buried underground all the year round, and is eroded by underground water vapor and electrolytic corrosion, w...
