FIELD: oil industry.

SUBSTANCE: invention relates to oil industry and can be used for repair of tubing. Robotic stationary complex for repair of tubing includes a process line for repair of tubing, containing a loading and unloading platform, an input control section, a cleaning section, section of couplings flap, section of non-destructive testing, cutting section, pipe threading line, section of couplings bloat, section of hydraulic tests, section of sorting and packing, control centre. Process line includes additional sections. Section of cleaning, control and sorting of couplings is made in the form of in-series located automatic equipment, which guarantees cleaning and control of thread, external and internal surfaces of coupling, and performs marking and sorting of couplings by strength groups. Gaging section includes two mirror-positioned automatic curvilinear control units, which provide control from both ends of the pipe without turning it through 180 degrees. Plugs and marking bloat section consists of automatic modules for applying lubricant to threads of tubing and coupling, automatic devices for supplying plugs and bloat to tubing and coupling, automatic device allowing to control output parameters of tubing and to perform marking on external surface. Incoming control section additionally includes a magnetic control module. Section for cleaning the tubing contains in-series installed automatic installation for cleaning of contaminated tubing, an automatic installation for cleaning the outer and inner surfaces of the tubing, an automatic installation for cleaning the tubing from salt deposits and a single water treatment unit. Section of couplings flap includes technical device for gripping and transfer of couplings in automatic mode to section of cleaning, control and sorting of couplings. Pipe-cutting line comprises two automatic pipe-cutting machines equipped with devices for automatic stop and positioning of tubing, plugs of inner cavity of tubing against ingress of lubricating fluid and chips during threading and automatic brushes with air blowing function for thread cleaning from chips, as well as two automatic test benches for thread control and hardening. Coupling bloat section further comprises an automatic couplings preload installation, which includes a couplings preparation module, made in the form of an automatic accumulator, which allows to ensure the couplings reception and sorting for storage according to strength groups, but not less than one strength group, receiving-feeding device, guaranteeing supply of coupling of required strength group, device for applying lubricant on coupling thread, tubing preparation module, which is a device for applying lubricant on tubing thread, and a coupling pre-turn module with torque control. Hydraulic testing section additionally includes a pipe drying device. Sorting and packing section includes automatic manipulator-stacker, which allows to sort tubing according to strength groups, classes and criteria of suitability, and automatic device for tubing packing. Complex further includes a process line for applying coatings on the inner surface of the tubing, comprising a tubing preparation section, consisting of a module of couplings flap, a module for preheating, thermal degreasing and drying pipes, an abrasive processing module, a blowing module and a surface quality control module, section for application of coating on inner surface of tubing, including module for application of protective coating and drying chamber, section for preparation and application of coating on inner surface of couplings, section for couplings bloat. Transport lines provide automatic movement of tubing between sections and process lines and allow simultaneous repair in a robotic stationary complex of tubing with coating and without coating.

EFFECT: improved quality of tubing repair, increased corrosion strength of repaired tubing, increased efficiency of operations during tubing repair.
