Description

Technical Field

[0001] The utility model relates to the technical field of oil mining, in particular to an anti-turbulence and anti-blowout pipeline. Background Art

[0002] The oil extraction process requires fluid pipelines with large flow and high flow rate. The flange and pipeline are connected by threads. Since there is a gap between the flange and the pipeline after the connection, when the pressurized fluid passes through the pipeline, there is a gap at both ends, which causes the cross-sectional area of ​​the flow channel to change, and then turbulence occurs. The fluid flow rate in the pipeline is very high, so the turbulence at this position will cause puncture leakage. Most fluids contain solid particles and are corrosive, which have an erosive effect on the pipeline. Long-term action will cause the threaded connection to fail, reducing the service life of the pipeline and causing fluid leakage, resulting in loss of life and property.

[0003] Therefore, there is an urgent need for an anti-turbulence and anti-blowout pipeline that can solve the above problems. Utility Model Content
