Vitrified clay pipe is capable of withstanding extreme temperatures. However, vitrified clay pipe is liable to damage by thermal shock – a swift change of temperature. Such rapid temperature variation induces thermal gradients inside the pipe wall which produces stresses which damage the pipe.
To guard against possible damage of vitrified clay pipe by thermal shock, engineers should check in design about the temperature of sewage to be carried, rate of flow, temperature of pipe and soils and the wall thickness of clay pipes.
