Coatings and Linings for Fittings


External Protection Options for Fittings

  • Fusion bonded epoxy coating 
  • Polyeurethane coating
  • Zinc rich paint with a bituminous paint or liquid epoxy finishing layer

Fusion Bonded Epoxy Coating

Fusion bonded epoxy coating is our standard coating and is applied in a state-of-the-art automated facility to coat DI fittings with powdered epoxy in a fusion bonding process. This coating is suitable for aggressive soil conditions and is applied both internally and externally to the fitting.

  • Pipes and FittingsIt provides excellent adhesion and a high gloss.
  • All shapes can be coated evenly.
  • It provides superior corrosion resistance.
  • There is a choice of the colour blue or red depending on whether it will be used for water or sewage.
  • Film thickness of 250 micron can be specified as per EN 14901.
  • A higher film thickness (above 250 micron) can also be applied if required by the customer.

Internal Protection Options for Fittings

  • Cement mortar lining

By agreement between manufacturer and purchaser, any one of the following linings may be applied depending on the type of liquid transported:

a)    Blast furnace slag cement mortar
b)    Sulphate resistant cement mortar
c)    High alumina cement mortar. Fittings with bituminous or epoxy seal coat over
      cement mortar are also available if required by customer.

  • Fusion bonded epoxy

Normally fusion bonded epoxy is applied both on the outer and inner surface of the fittings.

  • Ceramic epoxy

Ceramic epoxy lining offers excellent resistance to abrasion, mechanical damage and chemical attack. In pipelines conveying slurries or septic sewage this coating can provide a robust effective protection enhancing the longevity of performance.

All materials that come in to contact with potable water are certified by the appropriate approval agencies including WRAS, DWI, WRc, DVGW.
