Abstract

Protector (10) for protecting the male (3) or female (2) end of a tubular connecting member for excavation or exploitation of hydrocarbon wells, said end being equipped with at least one outer (4) or inner (17 26) threaded portion, an annular outer surface and an annular inner surface separated by at least one threaded portion, the protector (10) includes a first internal or external threaded portion having at least one first threaded section, the first threaded The section comprises at least one thread of pitch P1 capable of cooperating with the threaded portion (4) of the end to screw the protector on the end, and a second thread section having at least one thread of pitch P2, P2 Different from P1.

Description

technical field [0001] The present invention relates to tubular threaded components, and more particularly to protectors for the ends of certain of these components, in particular for the excavation of hydrocarbon wells and the ends of production tubing. Background technique [0002] Here "member" means any part or accessory used in the excavation or production of a well, and includes at least one joint or connector or threaded end for threaded assembly to another member to form a tubular with the other member threaded connector. The component can be, for example, a relatively long tubular part (especially a length of more than ten meters), such as a pipe, or a tubular set with a length of several tens of centimeters, or accessories for these tubular parts (hanger, "hanger", Section changing parts "cross-over", safety valves, drill pipe joints "tool joint", "sub" and similar accessories). [0003] The components are typically assembled to each other for running into a hydr...
