DEVICE FOR PROTECTOR FASTENING OF FLEXIBLE LONG-DIMENSIONAL PRODUCT TO PUMP-COMPRESSOR PIPE COLUMN IN AREA OF CLUTCH CONNECTING COLUMN PIPE Russian patent published in 2018 - IPC E21B17/10 F16L3/01 

FIELD: soil or rock drilling.

SUBSTANCE: invention relates to drilling equipment. Device for the tread mounting of a flexible long product on a tubing string contains a solid body with a channel for accommodating a flexible long product, and fixing elements connected to the housing, made in the form of metal tapes and intended for fixing the device on the pipes in the area of the coupling. Body is made of metal in the form of a monolithic lengthy spatial figure, formed by five conjugate cylinders, two of which are end cylinders, metal tapes of fixing elements are welded to them, and their forming elements are located on common straight lines parallel to the axis of the tubing in the working position of the device. Other cylinder of these five is a clutch cylinder, it is located in the middle of the body, and its generators are located parallel to the forming end cylinders with displacement relative to the forming end cylinders, due to the radius of the coupling, and are associated with the generator end cylinders by means of two transition cylinders with generators inclined relative to the end cylinders. Guide of each cylinder of the body is a figure including an arc defining the cross-sectional shape of the channel to accommodate a flexible long product, and two segments connected with the corresponding ends of this arc determine the planes of the device body to the pipe surface, so that each of these segments forms an external obtuse angle with a segment of a conditional straight line that is a chord of the indicated arc.

EFFECT: improving the reliability of fastening of flexible long products on tubing in the field of coupling connection and simplification of fastening technology.
