Determining the Tightening Force of the Threaded Elements of a Detachable Joint Based on Its Operating Conditions

Аннотация

Formulas for determining the required tightening force of the threaded elements of joints that experience particular changes in the course of use, such as variable loads, variations in the temperature of the working medium, and relaxation of the stresses in individual elements of the joint, are presented. An estimation of the length of the safe operation period of the joint until its next inspection is presented.
