Composite materials

"Transneft – Diaskan" produces composite materials for oil pipeline and oil product pipeline repairs based on CST. These materials consist of three components supplied as a set and mixed up directly before usage. The rated production capacity is about 55 thousand sets of composite materials.

The "ECM" class composite material is used as the base casting material and provide the following:

  • makes it possible to perform CST repairs of defective pipelines;

  • the CST repaired structure retains operation capacity for 30 years;
  • repairs can be carried out at pipe wall temperature of 4ºС to 40ºС, ambient air temperature of 4ºС to 40ºС and the temperature of the pumped product of -2ºС to +40ºС.

The polymer "PGM" class sealing material serves as a sealing compound:

  • it is used for filling the flanks of repaired structures;

  • it provides an opportunity to carry out repairs at pipe wall temperature of 4ºС to 40ºС, ambient air temperature of 4ºС to 40ºС and the temperature of the pumped product of -2ºС to +60ºС.
