VALVE COATING

Coating of valves using Belzona 1341 (Supermetalglide)

Industry: Water & Wastewater
Application: Erosion/Corrosion Protection of New Valves
Products: Belzona 1341 (Supermetalglide)
Customer Location: : SA, Australia
Application Date: Feb 2024

PROBLEM

A major water authority required an AS/NZS 4020:2018 approved coating on valves for erosion and corrosion protection.

APPLICATION

First, the valves were washed using high-pressure steam.  Thereafter the machined and sealing faces were masked and protected.  The valve internals were blasted to the SA2.5 cleanliness standard with a minimum blast profile of 75 microns.
