Product Coatings

Along with build quality, the longevity and reliability of couplings and other pipe fittings is highly dependent on the type and quality of the coating used. However, applying coatings to pipe fittings is not just about preventing corrosion, but can affect the evenness of flow through the pipe and the need to prevent contamination of pipe contents (.g. foodstuffs or drinking water).

Achieving this high quality, high performance finish requires careful preparation and a controlled environment.

Shot Blasting

Couplings and other pipe fittings are dismantled and all component parts exposed to full shot blasting to provide an optimum cleaned surface for complete coating adhesion.

Product Priming

A dedicated booth ensures complete priming of components, prior to Rilsan® coating, ensuring absolute coverage and adhesion.

Rilsan Fine Powders

A high quality, high performance finish requires careful preparation and controlled environment.

Rilsan® powder coatings have been used in the water industry since 1967. It is a unique, high performance polyamide providing a high degree of corrosion protection for metal parts whilst being compliant with the most demanding drinking water regulations (WRAS, KIWA etc.).

Manufactured from a renewable raw material (castor oil), Rilsan® is an environmentally sound coating that does not release any volatile organic compounds and whose composition is free of any heavy metal based pigments, and of curing agents.

To ensure their fittings meet their designated design life Viking Johnson uses Rilsan® as their corrosion protection coating to the majority of product lines. Selected not only for the coatings excellent protection against corrosion, Rilsan® withstands high levels of deformation making it ideal for Viking Johnson products that flex during bolt up. In addition, the coating resists impact damage making ideal for rough handling on site during installation.

Preserving Water Quality

Rilsan® coatings meet the requirements of the various regulations regarding the suitability of materials in contact with drinking water. They have been granted official approval in many countries:

  • France (circular DGS/VS4/N°99.217)
  • United Kingdom (WRAS and DWI certifications)
  • Germany (KTW and W270 certifications)
  • Netherlands (ATA certification)
  • United States (NSF61 listing)
  • Japan (Ministry of Health)
  • Australia (AS4020 certification)
  • Russia (Ministry of Health)
