Embodiment Construction

[0060] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0061] figure 1 It is a system layout diagram explaining the double piping structure of this embodiment. In addition, the system diagram shown in this figure is a piping when the double-layer piping structure of this example is applied to storage of oil (gasoline) in an underground storage tank. In addition, as an underground storage tank, in this example, an example of a storage tank buried under the ground of a gas station will be described.

[0062] In this figure, the underground storage tank 1 is provided with: an oil injection pipe 2 for injecting oil (gasoline); an oil supply pipe 3 for absorbing oil (gasoline) from the underground storage tank 1; a vent pipe 4 for underground storage ventilation of the tank 1 ; and a level gauge 5 for measuring the level of oil (gasoline) stored in the underground storage tank 1 . In addition, the underground storag...

Abstract

The invention relates to a double-layer piping structure, in particular to piping for oil such as crude oil, gasoline and petroleum. The provided oil piping structure is capable of early detecting corrosion or hole corrosion of piping buried underground and preventing soil contamination and the like in advance, the double-layer piping structure comprises a base pipe, a cover part, an oil leakage detection device and a notification device, wherein oil flows in the base pipe, the cover part is formed on the outer periphery of the base pipe, a plurality of spaces which are closed are formed in the cover part in the longitudinal direction of the base pipe, the oil leakage detection device is used for detecting oil leaked from the base pipe to the spaces of the cover part, and the notification device is used for notifying the outside of the oil leak information detected by the oil leak detection device.

Description

technical field [0001] The present invention relates to a piping structure for oil such as gasoline, and more particularly to a double-layer piping structure in which piping is arranged in double layers. Background technique [0002] At present, soil pollution caused by oil (gasoline) leakage or disasters caused by natural gas leakage have become important social issues. Many of these problems, such as oil leaks and natural gas leaks, occur when pipes become old or corroded due to years of use. [0003] Therefore, in existing gas stations, underground storage tank facilities, and other facilities that handle dangerous substances, the piping used is steel pipe (steel piping), and the outer surface is coated or coated for corrosion prevention. deal with. [0004] For underground storage tanks, inspection ports can be used to periodically inspect the interior for corrosion or pitting, and to repair, refurbish, as necessary. However, the pipes leading to the oil filling pipes...
