Customers Benefits 

  • High speed of protective film forming.
  • No emulsification is observed.
  • Stability of corrosion inhibitor at high temperature and high pressure.
  • High effectiveness of the inhibitor which allows to reduce the consumption of the chemical at treatment.
  • Compatibility of the inhibitor with other chemicals and materials. 
  • Low freezing point of the inhibitor.

Process Technique 

POLY-INCOR® 365 grade 011 inhibitor is normally injected continuously by a dosing pump.

The injection rate of POLY-INCOR® 365 grade 011 depends on fluid corrosiveness and is determined with laboratory tests.

For crude oil pipeline transportation systems consumption varies from 10 to 25 ppm, based on total fluid.

When applied in hole annulus of a well equipped with electric centrifugal pump, or for the downhole equipment protection the treatment must be performed periodically once per week or two weeks.

To obtain more detailed information about the chemical, determining its optimal consumption for the particular application or to organize laboratory tests,  please contact the specialists of Sales and service department of POLYEX, jsc. 


POLY-INCOR® 365 grade 011 is delivered in steel drums of 227 dm3 capacity or in PE containers of 1 m3 capacity.

Corrosion inhibitor POLY-INCOR® 365 grade 011 is certified for the application in oil and gas industry.
