Problems solved by technology

[0009] However, said device has the disadvantage that during transport or handling of the tubular part, said part and thus the ring protecting the device are caused to roll
The ring then rotates the guard, which, depending on the direction of rotation, may loosen the guard from the guard

Embodiment Construction

[0027] figure 1 A partial longitudinal cross-sectional view of a protective device 100 having a generally cylindrically shaped protective end 110 and a ring 120 is shown. Guard end 110 and ring 120 are coupled such that one cannot be displaced without the other. However, the ring 120 is able to rotate about itself independent of the guard end 110 .

[0028] In this embodiment of the invention, the protective means are intended to protect a part of the outer surface of the end comprising the internally threaded tubular part. figure 1 The tubular part is not shown in . The externally threaded region 112 of the guard end 110 is sized to threadably engage the internally threaded region of the tubular member. The term "threaded region" refers to any region belonging to the peripheral surface of the tubular member and comprising threads, which may be continuous, intermittent, regular, irregular, etc. Typically, tubular components include threaded regions meeting the specificatio...

Abstract

A device for protecting the end of a tubular component, the end including a first threaded zone. The device includes a protecting end including a second threaded zone configured to cooperate with a first threaded zone of the tubular component, and a ring configured to cover a portion of the outer surface of the end of the tubular component. The ring is bound up with the protecting end such that the ring is free to turn about itself independently of the end. Such a device may find application to components used for drilling and operating hydrocarbon wells, for example in particular expandable components.

Description

technical field [0001] The present invention relates to a device for protecting an end comprising a threaded tubular part used in the operation of a hydrocarbon or geothermal well. The invention also relates to a tubular part provided with protective means for its threaded end. Background technique [0002] Such a tubular part may for example consist of a long tube or link comprising an internal thread at one end intended to be connected to the end of another tube provided with an external thread. [0003] The tubular part is particularly useful in the manufacture of sealed casing strings or tubing strings for hydrocarbon wells or similar wells such as geothermal wells. [0004] More specifically, the invention relates to the protection of the threaded end of tubular components known as "expandable". The term "expandable tubular member" refers to a tubular member that undergoes an expansion in diameter of the order of 15% to 25% once installed in a well. The expansion ope...
