BELZONA PROTECTS PULSATION DAMPENER
Industry: Chemical & Petrochemical (PETR)
Application: VPF-Valves, Pipes and Fittings (VPF)
Substrate: Carbon steel
Customer Location: Offshore drilling company
Application Date: 1994
Problem: The rough surface caused by corrosion within the dampener was causing the diaphragm to be holed very quickly. This was leading to the drilling operation having to be shut down whilst the diaphragm was changed.
