Coated steel pipes


“WITH EPOXY POWDERS”

“WITH WATER-BASED LIQUID COATING”


Tecnocoat

The products coated at the Alfianello plant using the TECNOCOAT method are most used in the installation of fire-fighting systems, civil and industrial engineering plants and natural gas distribution networks.
They come in the size range DN 15 to DN 250.
TECNOCOAT coated steel pipes feature excellent temperature resistance, high mechanical properties and an impeccable defect-free appearance.
Coating can be applied on welded pipes, which are produced by TECNOTUBI, a company belonging to the Amenduni Tubi Acciaio Group, and on weldless pipes.


COATING WITH EPOXY POWDERS:
Production cycle

  • Visual inspection of the steel pipe surface
  • Cleaning of the surface of the pipe by means of steel grit blasting
  • Automatic pipe loading and feeding
  • Pipe pre-heating at 200°C, using an induction generator
  • Application of expoxy powders with electrostatic guns, average coat thickness 70-90 microns
  • Pipe cooling using continuous jets of water
  • Pipe marking
  • Checking the thickness and adhesion of the coat on the pipe
  • Packaging in bundles (hexagonal) using an air-operated strapping machine.


WATER-BASED LIQUID COATING:
Production cycle

  • Visual inspection of the steel pipe surface
  • Cleaning of the surface of the pipe by means of steel grit blasting
  • Automatic pipe loading and feeding
  • Check of wet coat applied
  • Transfer to the coat drying and baking furnace
  • Checking the thickness of the dry coat
  • Pipe marking
  • Packaging in bundles (hexagonal) using an air-operated strapping machine
