Embodiment Construction

[0051] The drawings may not only serve to supplement the invention, but may also contribute to its definition if necessary. The drawings do not limit the scope of the invention.

[0052] The object of the present invention is to determine the quality of the assembly of two threaded assemblies by detecting the occurrence of damage to the threaded portion, and / or the sealing bearing surface and / or the stop, during the assembly of the two threaded ends of the tubular assembly into a threaded joint.

[0053] "Female end" means the part of the component provided with machined and / or corrected surfaces, which part is intended to form a joint with the corresponding male part, and "body" means the part of the component which is located outside the And features parts that usually come from rolled surfaces. The female end typically has one or more threads on the inner side wall and is configured to be assembled to a corresponding male end having one or more corresponding threads on the...

Abstract

A device for determining the quality of assembly of a threaded tubular assembly comprising a frame (2) arranged to be mounted on a portion of the outer surface of the threaded tubular assembly; at least one measuring member (3), comprising a contact layer (4) comprising a plurality of temperature sensors (5) arranged to measure the temperature at a plurality of locations E(i,j) represented on the outer surface of the end of the tubular assembly value.

Description

technical field [0001] The present invention relates to the field of threaded tubular joints, and more particularly to an accessory for determining the quality of assembly of threaded tubular joints. Background technique [0002] "Threaded tubular joint" means an assembly of two tubular components assembled together by threads, a "component" being any element or accessory used to drill or produce oil and / or gas wells and comprising at least one connecting parts or fittings, or threaded ends. [0003] Components can be relatively long tubular elements (in particular about ten meters long), such as a pipe, or tubular sleeves tens of centimeters long, or accessories to these tubular elements (suspensions, section changing parts, safety valves, Similar to drill pipe connections, subassemblies, etc.). These components are usually made of steel. The unit is particularly suitable for components made of stainless steel, components with a high chromium content such as 13Cr or CRA ...
