This 3 layer corrosion protection high performance polypropylene (PP) coating consists of liquid epoxy layer, polymeric adhesive layer and polypropylene layer.
3 layer PP coating is designed to provide the most effective protection for buried and subwater oil, gas and water pipelines with high operating temperature in environments where superior mechanical protection and high operating performance characteristics are required.
Also it can be used for directional drilling and for road and river crossings becouse of excellent abrasion and impact resistance.
The unique application process of UKRTRUBOIZOL provides almost monolithic coating structure that can not be dislayed and prevents delamination and loss of adhesion. During construction, the coating demonstrates excellent field handling and flexibility characteristics, thus minimizing construction installation costs.
The epoxy layer provides excellent long term corrosion resistance and resistance to cathodic disbondment which reduces the cost of cathodic protection during the operation of the pipeline.
The adhesive layer provides superior adhesion between epoxy and PP layers.
The polypropylene layer provides the most durable pipe coating available and protects the pipes during transportation, handling and installation, thereby, reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.
Properties and Benefits:
1. The highest level of protection and resistance to mechanical damage, indentation, cathodic disbondment, soil contaminants.
2. Operating temperature range from - 20°C to + 120°C.
3. Long term corrosion protection on pipelines from 57 mm to 1020 mm in diameter.
4. It can be applied in a wide range of thicknesses (up to 10 mm) to meet unique project specifications and performance requirements and provide a high level of mechanical protection across many diverse environments without requiring the use of costly select backfill.
5. It has great field bending characteristics maintaining excellent adhesion and corrosion resistance properties.
6. It meets the requirements of DIN 30670, DIN 30678, BS EN 10288-2002, NFA 49-710, NFA 49-711, Ukrainian and Russian State standards and other.
