Scientific novelty
A new design of devices ensuring reliable fixation of pipeline ends against sudden displacement when cutting a main pipeline during repairs involving the replacement of a defective section, and centering the pipeline ends in all directions before welding a new section. Fixation and centering are carried out using a system of grippers and power cylinders; this developed design allows for pipeline repair with the minimum possible loads on the devices and stresses occurring in the pipeline wall.
Advantages
Unlike the currently used method of main pipeline repair using pipe layers, the proposed devices ensure a high level of industrial safety and technological efficiency of repair work by eliminating sudden displacement of pipeline ends during cutting through reliable fixation, ensuring pipeline centering in all directions, and eliminating time and labor costs for assembling and disassembling pipe layers. There is no need for financial costs to pay for permits for the transport of oversized equipment, which significantly increases the economic efficiency of the repair process. The proposed device design differs from existing analogues in its reliability, ease of operation, installation without additional excavation work, and the ability to control the process of fixing and centering the pipeline ends automatically or via remote control.
Commercial implementation
Devices for fixing and centering pipeline ends can be used by service divisions of companies involved in oil and gas pipeline transport, such as Gazprom Transgaz and Transneft.
