Pipe Systems With Enhanced Operational Reliability Manufactured by ChTPZ Group CJSC for Field Pipelines

About 200,000 km of internal field pipelines are being operated in the Russian Federation in ten oil companies. The reasons and factors for pipeline breakdown are as follows: • Lack of pipeline cleaning; • Low pipeline workload; • Ineffective program for inhibitor protection and corrosion monitoring; • Utilisation of washing and other process water into field pipelines; • Use of non-treated water in the RPM (reservoir pressure maintenance); • Low corrosion resistance and crack resistance of steels. The regulatory documentation (GOSTs) for oil and gas pipelines has become obsolete and does not take into account the enhancement of corrosion activity of oil field media fixed in recent years. Both internal field and pressure oil pipelines at oil fields are amenable to internal corrosion—pipes fail, as a rule, due to pit corrosion, less frequently due to groove (“rill”) corrosion. ChTPZ Group CJSC ranks the second in the Russian Federation by the volume of manufacture of pipes and welded connecting elements of oil tubular goods. Jointly with research centre specialists, in the course of a number of years it has been carrying out the development of oil and gas pipelines having an enhanced corrosion resistance and cold endurance. Pipes and connecting elements manufactured according new technologies have been operating without accidents since 1996 at a number of West Siberian and other deposits.
