POLYETHYLENE ENCASEMENT OF BURIED CONDUIT

Typically, buried conduit consists of products manufactured of reinforced concrete, steel or iron pipe, polyethylene, or a combination of these products. The longevity of the buried system depends on several design and installation features, including resistance to corrosion. There are numerous causes of corrosion, some of which are oxygen replenishment, presence of sulfides, pH of surrounding soil environment, likelihood of stray direct electrical current, and the influence of microbiologically induced corrosion. These factors, either singularly or in combination, indicate the need for increased attention to adequate corrosion protection of the buried system.
