FACTS
We are increasingly encountering unqualified service providers using incorrect products in pipelines, which often leads to further damage. It is crucial to educate yourself and ask the right questions to ensure proper pipeline maintenance.
Pipes Picote epoxy is preferred choice for brush coating pipes due to several key factors:
Designed for the job:
It’s important to note:
DC1000E 100% Solids Epoxy
Dual component epoxy used to rehabilitate concrete, PVC, fiberglass, clay, cast iron and ductile iron pipes. Creating a monolythic corrosion barrier or semi-structural repair of decayed and damaged pipes. Designed exclusively for the Picote Brush CoatingSystem.
All surfaces to be coated must be dry and clean, free from oil, grease, debris and other contaminants.
Concrete: must be jetted and cleaned removing any loose concrete.
Steel/Ductile Iron: Near-White SSPC-SP10/NACE 2. Acceptable methods: sand blast, chain flail, or Picote Smart Cutterand Side Grinding Panels
Stainless Steel: Nace No. 1/SSPC SP-5 White Metal Blast cleaning is needed and is beyond the capability of Picote cleaning tools. White metal blast cleaning is to be used to clean unpainted or painted steel surfaces prior to applying high-performance protective coating or lining systems. SSPC-SP 5/NACE No. 1 removes all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and any other foreign matter on the surface.
Number of coats required is dependent on pipe diameter and rehabilitation goal Estimated 30-50 year design life when using Semi-Structural Design Specifications.
Resistance to High-Pressure Water Jetting:
• Minimum 4 coats need to be applied.
• Maximum Jetting Pressure: 2600 PSI (180 Bar).
Corrosion Resistance: After cleaning metal pipes, corrosion will come back even quicker without coating
