Abstract

The invention discloses an anti-leakage pipeline for fuel gas conveying. The anti-leakage pipeline comprises a pipeline body, butt joint flange rings arranged at two end openings of the pipeline body,and mounting holes annularly and evenly formed in the butt joint flange rings. The butt joint flange rings are provided with loading grooves. An inner sealing ring is arranged on the inner wall of the attaching position of the pipeline body. An edge ring is arranged on the outer wall of the inner sealing ring. An isolation cover is arranged on the outer wall of the pipeline body, and the butt joint flange rings are located in the isolation cover. Through mounting of the isolation cover, secondary anti-leakage arrangement is formed at the pipeline butt joint position, and accordingly the situation that after natural gas leaks at the pipeline butt joint position, the natural gas is directly discharged into soil is avoided. When a natural gas detection alarm detects that natural gas exists in the isolation cover, buzzing is immediately given out, sounds are sensed through a sound control position indicator, GPS positioning information of the natural gas is immediately transmitted to a computer in a natural gas safety conveying monitoring room to be referred by safety management personnel, the leaked pipeline can be fast found, and emergency treatment is conducted in time.

Description

technical field [0001] The invention belongs to the technical field of gas transportation, and in particular relates to an anti-leakage pipeline for gas transportation. Background technique [0002] There are generally two ways to transport natural gas, one is buried pipelines, the other is elevated pipelines, and long-distance pipelines mostly use buried pipelines. [0003] The buried natural gas pipeline is connected by flanges, and the surface of the pipeline is coated with anti-rust paint, which can prevent the pipeline from being buried in the ground for a long time. There is a gap between the flanges. Packing, when the flange is locked by nuts and bolts, the flange can compress the asbestos packing. However, under the influence of the underground environment for a long time, the sealing performance of the asbestos packing will be reduced, so there is a problem of reduced air tightness. This will directly leak the natural gas into the soil, and emerge out of the ground...
