WELL TUBING AND COUPLINGS FOR IT

The well tubing is used during operation of oil and gas wells for transportation of fluids and gases inside the well strings, and for repair and round-trip operations. The well tubing is interconnected by means of threaded coupling connections. The threaded pipe connections ensure:
  • drillability of strings in complex-profile well bores, including that in the intensive deviation intervals;
  • sufficient strength for all types of loads and necessary leak-proofness of pipe string connections; the necessary wear resistance and maintainability.
The pipes are manufactured according to GOST 633-80, АРI Sрес 5СТ, and taking into account any special requirements of the consumer. The well tubing is supplied with protection of threaded pipe and coupling connections by means of corrosion preventing grease and threaded protective elements.
