  • the invention relates to the construction of pipeline transport and for pipes disassembled from gas pipelines during the overhaul of their linear part, relates to resource-saving technologies that allow reuse of pipes, including for subsequent installation of the linear part of the main gas pipelines.
  • a method for identifying sections of trunk pipelines predisposed to stress corrosion (see RU 2147098C1, 03/27/2000). The method is carried out by analysis of the design and actual position of the pipeline. The type of diagnosis is assigned depending on the length of individual sections, and the total lesion of more than 50% of the length of the sections between the cranes and the cameras for launching and receiving flaw detectors. Based on the diagnostic results, a type of preventive or repair work is prescribed that ensures the reliability of the pipelines.
  • a disadvantage of the known solution is the lack of methods and means of determining the suitability of the pipes for reuse.

Reference Guide, ed. AE Saroyan, M .: Nedra, 1987, p. 425-426).
  • the instruction regulates the procedure for preparing for reuse of longitudinally welded pipes, technical requirements for reusable pipes, methods, technology of work and execution of quality documents for pipes.
  • the instruction indicates that “depending on the specific conditions, the sequence and content of the individual stages of the work ... can be specified)).
  • the instruction does not define methods for the restoration of these pipes.
  • the pipes when carrying out quality control tests recognized as suitable for re-use, carry out their strength analysis and / or feed the pipes to a test bench, where the pipes are checked with a given test pressure.
  • the pipes when carrying out quality control recognized as suitable for reuse, carry out their strength analysis and / or feed the pipes to a test bench, where the pipes are checked with a given test pressure.
  • the invention explains the sequence of operations for the preparation of, for example, steel pipes dismantled from gas pipelines (MG) during the overhaul.
  • Pipes for reuse are pipes dismantled from gas pipelines, which have undergone preliminary examination and rejection under route conditions, and also additionally undergoing a comprehensive examination, technical examination of unidentified pipes, repairs and other technological operations in factory or basic (workshop) conditions.
  • Identification the procedure for establishing the conformity of a pipe to a quality document issued to it.
  • An identified pipe is a pipe for which its marking is in conformity with a quality document issued to the pipe during its manufacture and on which there is a marking (by branding, paint).
  • An unidentified pipe is a pipe that does not have a quality document (certificate) and / or is not marked with a stamp, and also a pipe for which it is impossible to establish the conformity of the marking with the quality document issued to the pipe during its manufacture (due to the poor quality of the certificate or marking).
  • a preliminary examination is a procedure for identifying obvious defects that exclude the possibility of reuse of pipes containing them, as well as determining the location and geometric parameters of defects.
  • the pipe sections disassembled from the main gas pipelines are cut into separate pipes.
  • the internal cavity of the pipes is cleaned of soil and foreign objects.
  • Category B pipe - a pipe dismantled from main gas pipelines (previously in operation), or with a production period of more than one year, not suitable for reuse in the repair of gas pipelines and intended for its further processing.
  • Pipes repaired without removal from the trench, as well as pipes removed from the trench, repaired on the edge and mounted within the boundaries of the repaired area defined by the design documentation (ranging from crane to crane) are not reuse pipes.
  • Pipes of category “A” and “B” are stored separately at the places of storage.
  • Category “A” pipes carry out their identification, mark pipes.
  • Pipes suitable for the primary screening are transported to the plant for further pipe processing. AT Under basic conditions, they carry out a comprehensive additional inspection and examination of pipes with preliminary processing of the ends of non-truncated pipes. So the pipes arriving at the factory site undergo an input visual and measuring control for rejecting pipes with obvious defects. A comprehensive inspection of the pipes is carried out in order to identify undetected during the preliminary examination of defects in the metal of the pipes and welded joints, as well as determine their location and geometric parameters. During the inspection, the geometric parameters of the pipe are measured: diameter, length, wall thickness, ovality, curvature, metal flaw detection is performed using non-destructive testing methods.
  • Pipes that passed the incoming inspection are divided into two groups: identified pipes, for which the marking is in compliance with the quality document (certificate) issued to the pipe during its manufacture, and on which there is a marking (branding, paint) and unidentified pipes for which there are no quality documents or it is not possible to establish the conformity of the marking with the document.
  • Pipes with old insulation are treated in basic conditions - they clean pipes from old insulation.
  • the criteria for the suitability of the pipes for reuse are determined on the basis of the valid regulatory and technical documentation approved by the established procedure for Gazprom enterprises.
  • Pipes with repairable defects are sent for preparation for reuse and subjected to restoration repair with quality control.
  • the method when conducting quality control recognized as suitable for re-use of pipes their strength calculation and / or feed pipes to the stand for hydraulic tests - hydraulic tests, where the pipes are checked with a given test pressure.
  • the pipes that have undergone repairs are formed in a batch, for which the necessary documents-certificates (passports) are drawn up.
  • the pipes indicate the guaranteed test pressure for each pipe.
  • Unidentified pipes are formed in a batch only after examination in terms of determining the chemical composition and grade of steel. Pipe lots are formed on the basis of the following requirements: pipe pipes must be dismantled from one gas pipeline, manufactured at the same plant, pipes must have the same diameter, wall thickness, steel grade, strength class. The identified pipes are formed in the batch without survey.
  • Pipes recognized in the process of inspection, inspection and repair as unsuitable for reuse are rejected, followed by the use of rejected pipes in technological pipeline networks, for example, water supply, as building elements, for example, piles or sent to scrap metal.
