Abstract

The invention relates to an experiment system for leakage characteristics of buried oil pipelines and belongs to the field of studies of leakage characteristics of buried oil pipelines. The experiment system can study the leakage characteristics of straight pipes, elbows, tee joints, flanges and valves. For the straight pipes, the elbows and the tee joints, the experiment system studies orifice leakage characteristics. For the flanges, the experiment system studies leakage characteristics of the flanges when the bolt pre-tightening force is not sufficient; for the valves, the experiment system studies valve inner leakage characteristics. The system which is formed by the connection of flanges is convenient to dismount, capable of studying the leakage characteristics of various parts (the straight pipes, the elbows, the tee joints, the flanges and the valves) and being widely applied to laboratory studies of colleges and universities and scientific research institutions and preliminary study of relevant enterprises.

Description

technical field [0001] The invention belongs to the field of research on leakage characteristics of buried oil pipelines, in particular to an experimental system for leakage characteristics of buried oil pipelines. Background technique [0002] Corrosion and perforation of pipelines, sudden natural disasters (such as earthquakes, landslides, river scouring) and man-made sabotage will cause pipeline leakage or rupture, threatening the safe operation of buried oil pipelines. Since the leakage rate is affected by many factors such as soil gravity, oil body temperature, shape and size of the leakage port, and the special environment in which it is difficult to conduct field experiments, it is very necessary to establish an experimental system for the leakage characteristics of buried oil pipelines. At present, the experimental systems for the leakage characteristics of buried oil pipelines at home and abroad can only conduct experimental research on the leakage characteristics o...
