Abstract

A protector for the male or female end of a threaded tubular connection for drilling or operating hydrocarbon wells, comprising a principal body, a first sealing gasket formed from a material which is less rigid than the material of the protector body and intended to make a seal with a surface of an end of the component, the principal body comprising a plurality of orifices through which the sealing gasket passes.

First claim

The invention claimed is:

1. A protector for the male or female end of a threaded tubular connection component for drilling or operating hydrocarbon wells, comprising:
a principal body; and
a first sealing gasket formed from a material which is less rigid than a material of the principal body and intended to make a seal with a surface of an end of the component,
wherein the principal body includes a plurality of orifices through which the sealing gasket passes,
wherein the principal body includes a plurality of bores into which the plurality of orifices open and through which the sealing gasket passes, and
wherein a diameter of each of the plurality of bores is greater than a diameter of each of the plurality of orifices.

2. The protector according to claim 1 , wherein the orifices are distributed about a periphery of the principal body.

3. The protector according to claim 1 , wherein the sealing gasket includes a ring, a sealing lip and a retaining extension.

4. The protector according to claim 3 , in which the retaining extension comprises a locking head.

5. The protector according to claim 4 , wherein the locking head has a tapered shape such that a diameter of a base of the locking head is larger than a diameter of an end of the locking head positioned outside of the bore, and
wherein the base of the locking head is positioned within the bore and bears on an opening surface of the orifice that faces in a direction of the bore.

6. The protector according to claim 3 , in which the retaining extension comprises a head stud.

7. A method for fitting a protector according to claim 6 , comprising:
placing a first sealing gasket on a body of the protector;
pushing a retaining extension through an orifice; and
cutting off the head stud.

8. The method according to claim 7 , further comprising:
pulling on a head stud of a retaining extension until the locking head passes completely through the orifice.

9. The protector according to claim 1 , wherein the sealing gasket is overmoulded onto the body of the protector and penetrates into at least one orifice.

10. The protector according to claim 1 , wherein the sealing gasket is formed from an elastomer.

11. The protector according to claim 1 , wherein the sealing gasket is intended to make a seal with a lateral surface of the end surface of the component.
