Vitrified Clay Pipe Engineering Manual

Clay pipe has been used in the construction of coined sewers, storm sewers and sanitary sewers in American cities since the early 1800’s. Much of the early pipe was terra cotta and should not be confused with today’s vitrified clay pipe. Vitrifiion is a critical difference. “Vitrifiion by definition is the progressive reduction and elimination of porosity of a ceramic composition with the formation of a …

Plastics

6 Plastics Technical Manual • While ABS, PVC and CPVC are ver y different materials, they share numerous advantages common to plastic piping systems. Advantages include ease of installation, corrosion resistance, low friction loss, initial cost, and longevity.

Resources

Fifty years of field experience confirm that PVC pipe more than measures up to the rigors of cold-weather installation and use. In fact, an easy-to-use product like PVC pipe becomes even more advantageous as temperatures decrease. PVC is widely used in Canada, Minnesota, and the Dakotas, so cold weather is not a limiting factor for PVC pipe
