GALLING-RESISTANT THREADED TUBULAR COMPONENT AND PROCESS FOR COATING SAID COMPONENT

A galling-resistant threaded tubular component for drilling or operating hydrocarbon wells has at one of its ends (1; 2) a threaded zone (3; 4) produced on its external or internal peripheral surface depending on whether the threaded end is male or female in type, with at least one portion of the th...

Beschreibung
Zusammenfassung:	A galling-resistant threaded tubular component for drilling or operating hydrocarbon wells has at one of its ends (1; 2) a threaded zone (3; 4) produced on its external or internal peripheral surface depending on whether the threaded end is male or female in type, with at least one portion of the threaded zone (3; 4) being coated with a dry film with a crystalline structure with a high specific surface area principally constituted by one or more mineral salts which are not reactive towards metals. It also concerns a process for coating such a component using a dry mineral film with a crystalline structure having a high specific surface area principally constituted by one or more mineral salts which are not reactive towards metals.
