THREADED TUBULAR COMPONENT AND METHOD FOR COATING SUCH A THREADED TUBULAR COMPONENT.

摘要

The subject matter of the invention is a tubular element intended for drilling and/or operating hydrocarbon wells having one end (1; 2) comprising at least one threaded area (3; 4), characterised in that the end (1; 2) is at least partially coated with a dry film (12), comprising a matrix (13) including a mixture of at least one alkali polysilicate and at least one semi-crystalline thermoplastic organic polymer. The invention also relates to a method for producing a dry film (12), comprising a matrix (13) including a mixture of at least one alkali polysilicate and at least one semi-crystalline thermoplastic organic polymer, on such a tubular element intended for drilling and/or operating hydrocarbon wells.
