How are fittings constructed for use with concrete pressure pipe?
Fittings for concrete pressure pipe such as elbows, tees, branch wyes, adapters, and reducers are constructed with steel plate rolled, cut, and welded. Usually, the interior and exterior surfaces receive a portland cement mortar protective coating. For fittings used with pre-stressed concrete pressure pipe, the fittings are not pre-stressed. The steel plate thickness is sized to handle the expected internal pressures and external loads.
