Fracturing hose for high-pressure oilfield

Abstract

A fracturing hose for a high-pressure oilfield includes: a hose and a connector disposed at an end of the hose, where an outer wall of the connector is provided with a limit groove and a flange; a limit assembly is disposed in the limit groove; the flange is sleeved outside the connector; and the limit assembly is configured to limit a position of the flange. The limit assembly can replace the limit screw used in the prior art. Without the limit screw, the limit assembly can also be mounted conveniently, and axially limit the position of the flange, thereby effectively preventing the situation that the limit screw is cut off by the flange in the prior art. When the flange moves relative to the connector and the limit assembly falls off the flange, the limit assembly can still remain as a whole on the limit groove.
