METHOD OF TIGHTENING OF GROUP THREADED CONNECTIONS

摘要

fine mechanical engineering. SUBSTANCE: method may be used for tightening of standard group threaded connections, for example in process of assembly of high- pressure vessels. In tightened responsible group threaded connection tightening forces of single threaded connections included in group connection are balanced up to the same preset value by using mechanoelectronic system controlled by computer. EFFECT: enhanced reliability of sealing.
