Mininig - Informatics Automation and Electrical Engineering
Theoretical study of dependence of screwing of drilling-pipe connector on thread-process cutting tool profile Screwing is one of the main parameters of the quality of a drill string tapered thread tool joint. It indicates the number of screwing operations that can be applied to this tool joint during drilling. Tool joints that have undergone rejection (determined by a specific criterion -the distance between the end faces of the pin and the box before they are start the screwing) are not
