Beschreibung
Zusammenfassung:	A conduit and an integrated system for utilizing same, such as a foam control spray system for a sewage treatment facility, where said conduit is exposed to a hostile environment, such as solar ultraviolet (U.V.) radiation. The conduit and transmission components of such system comprise tubular members consisting of a solar U.V. degradable plastic, such as polyvinylchloride (PVC), having a preferred outer layer of metallic zinc diffusion bonded thereto, such as by spray arc metallizing the zinc onto the plastic surface, whereby the zinc prevents deterioration or breakdown of the plastic from solar U.V. radiation.
