Shock-absorbing pipeline structure

Abstract

The invention relates to a shock-absorbing pipeline structure. The shock-absorbing pipeline structure comprises a plurality of branch pipelines and a plurality of fixed sleeves. The branch pipelines are one more than the fixed sleeve in quantity, adjacent two branch pipelines are connected through the fixed sleeve, the fixed sleeves and the branch pipelines are in interference fit and the fixed sleeves are welded and fixed out of the branch pipelines, and a plurality of buffer tanks are arranged on the outer walls of the fixed sleeves. The shock-absorbing pipeline structure provided by the invention has the advantages of being simple in structure, easy to process and mount, low in cost, light in weight and the like, and can improve the anti-fatigue performance of the pipeline, prevent the pipeline from being buckled and damaged, and reduce stress concentration.

Description

technical field [0001] The invention relates to a pipeline structure, in particular to an anti-seismic pipeline structure. Background technique [0002] As we all know, earthquakes are sudden natural disasters that do the greatest harm to society and human beings. As a country with strong seismic activity in the world, earthquake disaster is one of the most serious natural disasters in my country. However, for long-distance buried pipelines, the biggest problem besides corrosion is earthquake. According to a large number of earthquake damage statistics, the damage of buried pipelines in earthquakes generally occurs in active fault zones. When the long-distance buried pipeline crosses the fault, due to the large dislocation of the ground in the fault area, the buried pipeline will deform with the deformation of the soil, and will be affected by the lateral and axial soil reaction forces from the pipeline, so when the pipeline When under tension, if the tensile strain excee...

AI Technical Summary

Problems solved by technology

In short, the existence of faults poses a huge threat to the operation of buried pipelines. Once a long-distance pipeline accident occurs, it will not only cause oil and gas leakage, pipeline suspension, and bring huge economic losses, but may also cause fires, explosions and other accidents. , have serious consequences and adverse effects on life and property, the natural environment and social stability
