摘要

P THE INVENTION RELATES TO A PROCESS FOR DETERMINING THE TIGHTENING TORQUE TO BE APPLIED TO A JOINT FOR TUBES, INTENDED FOR THE PETROLEUM INDUSTRY DETERMINING ON THE MALE ELEMENT AND ON THE FEMALE ELEMENT A LOCATION SUCH WHEREAS, WHEN THE TWO REFERENCES ARE BROUGHT IN FRONT OF THE OTHER, THE TIGHTENING LIMIT STOP 2 OF THE MALE ELEMENT 1 AND THE FEMALE ELEMENT COME INTO CONTACT WITH EACH OTHER; AFTER COATING WITH GREASE, THE TIGHTENING IS CARRIED OUT BY APPLYING A SUFFICIENT TORQUE TO TURN AN ELEMENT RELATIVE TO THE OTHER BY A PREDETERMINED ANGLE BEYOND THE POINT OR THE MARKS ARE ONE IN FRONT OF THE OTHER, AND THAT WE MEASURE THE TORQUE; WHEREAS THIS OPERATION IS RENEWED ON A SUFFICIENT NUMBER OF JOINTS; AND THAT THE FIELD OF TIGHTENING TORQUES THAT ARE TO BE APPLIED TO JOINTS OF THIS TYPE WITH THE GREASE THAT WAS USED IS DETERMINED. /P
