The valves in geothermal wells can be properly protected by weld-overlay cladding with a corrosion resistant alloys (CRA) in the insides of the valves or at the exposed surface with the aggressive geothermal fluids such as acidic or low pH discharges or hyper-saline geothermal brine. Valves are the primary equipment of control in handling geothermal fluids for the geothermal wells and gathering system. It is integral that the equipment can do the work at an aggressive geothermal fluids chemistry without worry of corrosion of the critical parts inside the valves.
Wilclad can supply geothermal purpose and specification CRA cladded valves such as Master Valve, Through Conduit Valve (TCV), Wing Valve, and Motor-Operated Valves (MOV). Geothermal client can also provide stock material and Wilclad will provide cladding services.
Cladded Master Valve
Cladded Wing Valves
Cladded Wellhead Assembly
Cladded Casing Head
Cladded Angled Port Spool
Cladded Production Cross
Cladded Production Tee
Cladded Piping and Fittings
For a fully protected piping system, weld-overlay cladding with CRA application must also be included in the piping, fittings, Injection and sampling spools. It is our aim to provide full system protection and not allow a gap where the corrosion or erosion problems can attack in the system
