FIELD: process engineering.
SUBSTANCE: invention relates to joints between pump rods, couplings of tubing strings with the help of system of pipe wrenches. Required pressure acting on first joint by the system of pipe wrenches is defined. Determined pressure is displayed on monitor. Actual pressure acting via system of pipe wrenches at each joint is defined. Required pressure action at each joint of said joint is verified. Said actual pressure is recorded and displayed on the monitor. Said actual pressure and required pressure are estimated to determine if each stays in preset pressure range.
EFFECT: process control and indication.
