  • Comprehensive approach to ensuring the integrity of high-pressure gas pipeline DN 400 conference presentation in PDF (11483 kB)

Comprehensive approach to ensuring the integrity of high-pressure gas pipeline DN 400

The gas flow through Polish pipeline systems have been gradually changing from the east-to-west, to the opposite direction in the last few years. Based on this fact, a requirement to increase the capacity of gas pipelines to transport gas at the pressure of 7.4 MPa has occurred in some Polish regions.

This is achieved not only by the construction of new high pressure pipelines but also by integration of older revalidated pipelines operated in the past at the lower pressure into the pressure level of 7.4 MPa. A concrete example of this comprehensive approach to ensuring the integrity was revalidation of 55 km long gas pipeline DN 400 in south-western Poland.

See the presentation Comprehensive approach to ensuring the integrity of high-pressure gas pipeline DN 400 (PDF, 11483 kB), that our representatives presented at the 8th Pipeline Technology Conference, in the 2013, in Hannover, Germany.

Revalidation included the following basic steps:

  • cleaning the pipeline,
  • performing of in-line inspection by MFL tool,
  • material test of samples taken from the original pipeline,
  • model integrity test of pipe body vessel from a pipe taken from the original pipeline,
  • design of working procedures for integrity test,
  • preparation the pipeline for testing,
  • integrity test performance and drying by super dry air,
  • final report.

For in-depth information, see the related project, Comprehensive integrity verification of the high-pressure pipeline DN 400.
