The invention is illustrated in the drawing. In FIG. 1 shows a General view of the complex that implements the method.

The complex contains equipment installed in the course of a single technological process with a stream of pipes equally oriented by the pipe coupling, which is mounted in functional modular units that are moved assembled and connected by an ACS computer network and transport mechanisms. The equipment includes an input expansion rack 1, a device 2 for controlling the pipe curvature, a unit 3 for cleaning the pipe from contaminants, a unit 4 for non-destructive testing and diagnostics of the pipe body, a unit 5 for input optical quality control of threaded elements, a unit 6 for additional technological marking of pipes, pipe-cutting machine equipment 7 for repair of threaded elements by machining, clutch-turning machine 8. Equipment of the complex contains installations 9 and 10 of ultrasonic processing of pipe and m thread threads, respectively, installation 11 of hydraulic testing of pipes and installation 12 of acoustic emission monitoring of installation 13 of stripping the threads of the coupling and 14 applying anti-seize coatings on the coupling thread, the block 15 of the finishing metallization of the thread of the coupling with a special conductor mask, the installation of 16 optical quality control of the coupling threads 17 internal cleaning, installation 18 applying a corrosion-resistant coating on the inner surface of the pipe, installation 19 drying the coating, installation 20 of the output control of the pipe body, installation 21 optical quality control of pipe threads, installing 22 the final marking, sorting rack 23, communication control unit 24 and ACS units input information labeled tubes into a database ACS. The complex introduced an additional technological route-processing section of couplings 25, as well as an additional clutch-turning machine 26 of section 27 of unscrewing couplings. Coupling machine 26 is installed at the inlet of the complex until 4 non-destructive testing and diagnostics of the pipe body are installed, forming a branching stream into technological streams for processing pipes and couplings. Coupling machine 8 is located between the installation 9 of the ultrasonic processing of pipe threads and the installation of 11 hydraulic tests. The location of the coupling machine 8 and the equipment of the screw coupling section corresponds to the attachment of the connection of the formerly closed threaded element of the coupling and the pipe threaded element, which was closed, and mainly of the elements that were connected to each other. At the junction of the technological streams of pipes and couplings in front of the coupling machine 8, there is a coupling processing section 25 connected by a conveyor feeding the couplings to the output of the couplings 30 of the screw unscrewing section 27 of the closed threaded joints, and the output of the optical coupling quality control unit 16 of the coupling threads is connected by the conveyor 31 to the screwing section 28 couplings selectively according to the recommendations of the expert display 32 ACS. Installation 5 of the input optical quality control of pipe threaded elements is connected to the automated control system by means of an expert unit 33, a unit 34 for reading the number of the virtual additional marking of the pipe, and a unit 35 for reading the number of the virtual marking of the coupling, and the unit 36 for expert processing of the data for controlling the threads, including pipe sorting repairable to obtain a certain class of pipes, according to the program in block 37 of the ACS task for processing a batch of pipes. The installation 21 of the output optical control of the pipe thread is connected to the ACS database through the virtual pipe number reading unit 34 and is connected to the laser automatic tube marking unit 22, which is located in one structural unit with the installation 21. The marking unit 22 is connected to the ACS, which, in its the turn is connected with the block 38 of the automated configuration of sections of pipe columns of a given type in the output shelving pockets 39. Block 38 contains a printing device for issuing protocols to the completed pipe sections columns.

The method using the proposed complex is as follows.

Preparation for operation is used both for homogeneous sets of pipes and for composite columns, for example, lift columns of tubing, including sections from new pipes 73-5.5 GOST 633-80 (AR15B) of various strength groups, pipe sections of a similar assortment , which were in operation, restored to match the residual wall thickness of the first or second class, as well as sections of pipes of a special class with a resource that exceeds several times the standards for new pipes in the state of factory delivery.

Before starting work with the next batch of pipes, through the block of 37 tasks, the ACS of the complex introduces a basic task that defines the requirements for the quantitative and fractional composition of pipes of various classes, sets, for example, sections of elevator columns to be prepared for operation from a specific batch of pipes.

A batch of pipes is sequentially rolled out at the input rack 1, where they provide the same orientation of the pipes, for example, with couplings forward along the complex. At installation 2, pipes that are not repairable by curvature are rejected; at installation 3, pipes are cleaned of grease and mechanical impurities. At the entrance to the unscrewing section 27 of the couplings, virtual additional marking of the pipe and coupling is automatically performed, assigning them temporary technological numbers by means of the tracking and numbering unit of pipes and couplings included in the ACS. In the unscrewing section 27 of the couplings, by means of the clutch-turning machine 26, the closed connection of the clutch with the pipe, fixed in the factory, is unscrewed, then the process stream is divided into streams of couplings and pipes. In the first, at the output of the couplings 30, couplings with obvious defects are visually rejected, a signal is given for the rejection of the next virtual clutch number through the clutch tracking unit 35 in the ACS. Visually recognized maintainable couplings, storing their virtual numbers in the memory of the ACS block 35, are sequentially placed in the slots of the conveyor 29 and the couplings are delivered to the coupling processing section 25.

The next pipe, deprived of clutch section 27, is sent to the pipe outlet through the automated control system and then to the pipe body installation 4 using the automatic control unit 34, along the live roll to monitor the pipe body, tracking its virtual number and entering the geometry into the operational database of the automated control system, the measured geometry parameters and pipe strength group. Further along the conveyor pipe, and through a computer network, its virtual number is transferred to the optical input inspection unit 5 of the pipe thread, which is part of the ACS, where an expert assessment of the potential maintainability of the pipe threaded elements is carried out sequentially until the pipe reaches the highest class in accordance with the basic task in the block tasks 37 ACS complex. The technological conditions of mechanical and / or ultrasonic processing of pipe threads in connection with its virtual number are set through the ACS block 36 via a computer network, including information about the need to change the quantitative composition of operations of the processing mode on them. In general, by means of an automated control system, technological pipe streams are divided into only ultrasonic treatment streams by units 9 and a mechanical processing stream by machine equipment 7, followed by supply to control units 4 and 5 and subsequent ultrasonic treatment by units 9. In a particular case, if necessary, an automatic control system automatically opposed to the installations are automatically switched on 9 technological installations for cutting the end and grinding the chamfer on the pipe threaded element, block 15 for finishing metallization of the thread of the coupling with a special conductor mask, a special coupling plug for additional crimping of metallization coating elements during hydraulic testing of the pipe. When ultrasonic processing of the pipe, potentially repairable to obtain a pipe of a special class, by means of the ACS block 36, the conditions for the technological transition of the additional ultrasonic modification of the pipe thread by the units 9 are set and implemented.

Similarly, the instructions of the ACS expert unit 36 are automatically fulfilled in the coupling processing section 25, where after ultrasonic processing of the threads with the installations 10, grinding of the threads with the installation 13, metallization of the threads with the installation 1 5 and quality control of the threads with the optical installation 16, the couplings are transferred by the conveyor 31 to the section 28 for screwing the couplings onto pipes selectively according to the recommendations of expert block 36 ACS, presented to the operator through the display 32. Visually checking compliance with the norm of the conditions for manual make-up, feed the pipe by gangu muftodovertochnomu machine 8 to produce a closed dokreplenie threaded joint, monitoring the progress of the process on the display 32. The tube assembly with the clutch guide on the roller tables 11 for installation by applying a hydro installation 12 acoustic-emission control test stroke. After completion of the tests, the pipe is unloaded and fed in general to the installations 20, 21 and 22 of the outlet inspection and marking section of the pipes. In the particular case, if necessary, when the pipe moves along the roller table, the internal cleaning unit 17, the anti-corrosion coating application unit 18 and the coating drying unit 1 9 are put into operation. In the installation 20, the output control of the pipe body is carried out, in particular, along the length, the compliance of the control data of the pipe body with the installation of 4 virtual number of the incoming pipe is checked, in the installation 21 of the optical quality control of the thread is checked for compliance with standards and technological conditions. The results of the output control through the device 24 for communication with the ACS are passed to the block 36 expert data evaluation. At the same time, the installation of 22 final automatic laser marking of the pipe in accordance with the standards, as well as the current number. The device 24 automatically enters information about the marked pipe, including the class, strength group, the geometry of the thread and the body of the pipe, the complex of operations performed on the pipe and the coupling in the ACS database, long-term storage. Then the pipes are sorted from the rack 23 into the output shelving pockets 39 through the block 38 of the automated configuration of the sections of pipe columns, either automatically using the ACS as the control, according to the program specified in the block 37 of the ACS, or when using the ACS as an expert manually taking into account visual information displays of installations 38, 20, 24, 21 and 22. By means of a printing device of block 38, the completed sections of pipe columns are accompanied by output control certificates containing characteristics of an individual These are the label numbers of each pipe. Moreover, the degree of accuracy of indicating the resource of the produced pipe, the class level are determined by the level of requirements for the ACS task block, which is associated with the refinement of the cost of processing at a given level.

The use of the invention allows to reduce the unit cost of preparing for operation of tubing due to a more accurate determination of the state of the pipe body, its thread, including closed in the factory connection of the pipe with the coupling. The use of an ACS system in this invention provides a choice of technology individually adapted to each threaded element while maintaining the positive aspects of the mutual running-in of closed threads during previous operation.

With the maximum use of the technical capabilities of the complex and method, in accordance with the invention, the treated pipe, including the one that was in operation, has a guaranteed thread life 3-4 times higher than the pipe of the same grade in the state of factory delivery.
