NAGOAKA’s CERA-COAT screen offers ceramic coating designed to resist electrical corrosion of metallic screen surfaces, which is a common problem in many water wells. Its applications include pollution remediation wells where severe corrosion problems often exist and where stainless steel screens fail. As an economic option, the screen can be constructed with a carbon steel base material coated with the CERA-COAT corrosion-protection layer. NAGOAKA U.S.A. Corp.
