The strong, long-lived metal pipe used for water mains, fire lines and heavy-duty crossings, and how it is installed and protected.
Ductile iron is a tough, flexible cast iron that can take high pressure and heavy loads. Utilities use it for water mains, fire lines, force mains and crossings where strength matters. It is heavy, so installing it takes equipment, but it is known for a long service life.
Joints are usually push-on gaskets or mechanical joints, and fittings are heavy iron with restraint to resist pressure. Soil can corrode iron, so pipe is often wrapped in polyethylene encasement or coated, and tracer wire or locating methods are used since metal pipe is easier to find with a locator.
