Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of petroleum mining, in particular to an anti-erosion elbow. Background Art
[0002] The oil extraction process requires connecting pressurized fluids to drilling equipment through pipelines. Depending on the well site layout and process requirements, connecting pipelines often require diversion or redirection, necessitating the addition of transition elbows. Because the change in direction of the fluid within the pipeline at an elbow results in energy loss, the flow rate often needs to be increased. Furthermore, the fluid can contain solid particles, which can erode the elbow, reducing its service life.
[0003] Therefore, there is an urgent need for an erosion-resistant elbow that can solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide an erosion-resistant elbow to solve the problems existing in the above-mentioned prior art.
