Description
Technical field
The invention belongs to attachment device technical field, specifically a kind of petroleum pipeline bending resistance square ring flange.
Background technology
Flange is called flange flange disk or flange.Flange is the part being connected with each other between pipe and pipe, is used for pipe end
Between connection；Also have with the flange imported and exported in equipment, the connection being used between two equipment, such as speed reducer flange.Method
Orchid connection or bump joint refer to being connected with each other as the removable of one group of combined sealing structure by flange, gasket and bolt three
Connection.Pipe flange, which is meant, matches effective flange in plumbing installation, with the inlet and outlet flange for meaning equipment in equipment.On flange
Perforation, bolt make two flanges be close to.With liner sealing between flange.Flange point is threadedly coupled (screwed connection) flange, welding
Blue and clip flange.Flange all uses in pairs, and low pressure pipeline can use silk acting flange, the use of four kilograms of pressure above
Welded flange.Gasket is added between two panels ring flange, is then fastened with bolt.The flange thickness of different pressures is different, they
The bolt used is also different.Water pump and valve, when being connected with pipeline, the part of these equipment facilities is also made corresponding
Flange shape, also referred to as flanged joint.
In the prior art, some are embedded in the oil pipeline of underground, these pipelines are when passing through flanged joint, accordingly
Support force in its junction is more weak, and the covering weight above pipeline applies pipeline larger moment of flexure so that pipe
The junction in road easy bending or fractures under the action of moment of flexure, causes pipeline leakage.
Invention content
