Cast iron is the premier piping material for sanitary and storm drain, waste, and vent applications. Extra Heavy pipe/fittings have greater wall thickness and higher crush strength than service weight. They are for non-pressure applications where temperatures will not exceed 212 deg F. They are perfectly suited for underground industrial applications and are commonly installed under airport runways or where heavy traffic loads are expected. Charlotte Pipe products are manufactured in the USA.
