Client
Reservoir, UK.
Scope of Work
A 36” inlet flow control valve had been in service for 60 years at Ladybower reservoir, one of three reservoirs in the Upper Derwent Valley in Derbyshire, England.
Products
Polyglass VEF: An excellent in immersed environments and is resistant to chemicals across the pH range. WRAS approved VEF is suitable for town water and potable water service.
Coating System
The valve parts, 5 in all, were delivered to our Leeds workshop where they were abrasive blasted to achieve the required cleanliness standard, before being thoroughly cleaned down and vacuumed. Multiple coats of WRAS approved Polyglass VEF were then applied to reach the client’s specified DFT of 1000µm. After suitable curing, thickness and spark testing was carried out and final visual inspection made to ensure the quality of the coating work completed. The vessel was then prepared for dispatch to the customer and subsequent recommissioning.
Coating Credentials
The protective coating will enable a significantly extended service period for the valve. The customer can also expect a fast return on investment due to reduced maintenance intervals, that take the valve out of service, being required. Good for another 60 years.
