Internal anti-corrosion coatings

Internal smooth epoxy coating (40-150 microns)
Internal anti-corrosion coating (200-1000 microns)

Coatings of this type are a type of smooth epoxy coatings designed to be applied to the inner surface of pipes in the factory to increase their throughput capacity and reduce transportation costs. They are intended for use in main gas and oil pipelines.

Internal smooth epoxy coating (40-150 microns)

The internal smooth epoxy coating of 40-150 microns from UKRTRUBOIZOL allows increasing the volume of pumping of pipeline contents by up to 10-15%, as well as reducing the cost of purchasing pipes by reducing the diameter of pipes, their wall thickness and reducing the operating pressure of the pipeline.

In addition, this type of pipe with an internal coating has anti-corrosion properties – a smooth epoxy coating protects the inner surface of pipes during storage and transportation from destruction as a result of interaction with the environment, preventing the occurrence of bacteriological corrosion. This coating, due to its almost mirror-like surface, reduces the cost of internal pipe cleaning during pipeline operation.

Technical specifications
  • Diameter of pipes to be coated: from 57 mm to 1420 mm
  • Recommended smooth coating thickness: 40 - 150 microns (the value may vary depending on customer requirements and specific production conditions)
  • Operating temperature: -40 to +180 °C
  • Meets the requirements of API RP 5L2, Ukrainian National Technical Standards, etc. (Note: coating specifications are regulated by the manufacturer's requirements or customer's wishes).
The main advantage of using a smooth coating is that it reduces the friction of the working medium against the wall, thus reducing the cost of transporting the medium, as well as the cost of transporting the medium:
  • Easy and fast commissioning of the pipeline (due to its unique anti-corrosion properties, the internally coated pipe practically does not age and does not undergo oxidation during storage, so there is no need to spend money and time on cleaning it from rust and dirt).
  • Fast payback (the internal coating pays for itself in 3 to 5 years due to energy savings in compression and pumping during the operation of the pipeline system).
  • Perfect cleanliness of the coating due to the fact that the composition of the coating does not affect the composition of the working environment.
  • Reducing the cost of replacing valves (in pipeline systems made of pipes without a protective coating, valves fail most often due to gas contaminated with oxidation products).
  • Improving the quality of substance transportation (reducing the level of gas flow turbulence due to the smooth inner layer of the coating leads to a decrease in the number of critical states determined by the mode of gas movement).
  • Reducing the financial provision for pipeline maintenance due to the ability to reduce the diameter of pipes by increasing the overall capacity of the pipeline

Anti-corrosion epoxy coatings are applied in the factory to the inner surface of pipes to protect the pipe from internal corrosion, which in aggressive environments can reach 1 mm (pipe wall thickness) or more in a month.

Internal anti-corrosion epoxy coating (200-1000 microns)

Anti-corrosion epoxy coatings by UKRTRUBOIZOL protect industrial pipelines, oil and water pipelines during operation, as well as during storage and transportation of pipes.

Additionally, UKRTRUBOZOL anticorrosive epoxy coatings have an almost mirror-like surface and are highly smooth, which, in addition to their anticorrosive properties, also gives them the properties of smooth coatings, increasing the pipeline capacity, reducing the amount of deposits on the inner surface of the pipe, and reducing the cost of in-pipe cleaning during pipeline construction.

When used for water pipelines, it improves water quality and reduces pipeline fouling.

Properties and advantages of UKRTRUBOIZOL anti-corrosion epoxy coatings:
  • They are used in pipelines for: oil (crude, high hydrogen sulphide, water, paraffin), water (drinking, industrial, sea, waste, sewage), jet fuel, chemicals, etc.
  • Excellent long-term corrosion protection during pipeline operation, storage and transport of pipes.

  • Operating temperature of the pipeline from - 40°C to + 120°C.

  • It is applied to pipes with a diameter of 42 mm to 1422 mm.
  • Recommended coating thickness: 300 - 350 microns, and can vary (from 100 to 1000 microns) depending on customer requirements.
  • They help to increase pipeline throughput, reduce transportation costs and in-pipe cleaning during pipeline construction.
  • They have high mechanical and impact strength, abrasion and bending resistance, while retaining all their working properties.
  • Meet the requirements of national and international standards.
