PROCEDURE AND DEVICE FOR DETERMINING THE FASTENING TORQUE OF A TUBULAR JOINT PROVIDED WITH A CONICAL SCREWTHREAD AND A FASTENING LIMIT STOP, USABLE IN THE PETROL INDUSTRY

摘要

The invention relates to a method for determining the screwing torque is applied to a joint for tubes, intended to the industry of oil according to which will determine on the element on the male and female element a repere such that, when the two landmarks are induced facing one another, the limitation thrust screwing 2 of the male element 1 and the female element, come into contact with one another and that, after having been coated with grease, it is related to the screwing, by applying a sufficient torque to turn an element with respect to each other by an angle predetermined the - of the point or landmarks are opposite one another, and that it is desired to measure the torque, it repeats this operation on a sufficient number of joints, and determine the field of the pairs of screwing, that is to be applied to the seals of this type with the grease which has been used.
