Vitrified clay pipe Production and Benefits



VCP pipe is made by forming clay then heating it to 2000 degrees Celsius. The pipe is then vitrified. In some areas the pipe is then glazed to ensure that it will be water-tight.


VCP products use clay as a major component in its production, making its raw materials environmentally friendly. The manufacturing process has been fine-tuned for centuries and was designed to be fiscally responsible which had the added benefit of being environmentally responsible. But the primary benefit (both environmental and fiscal) of using VCP in sanitary sewers is its long service life.

As Sanitary Sewer Overflows (SSOs) have become an area of concern for the US EPA and thus a very large potential liability for municipalities, cleaning sewers for condition assessment and maintenance has become a critical factor in system design. Flexible thermoplastic pipe limits the tools available for this cleaning as they are more easily damaged. VCP allows for aggressive cleaning methods which prolongs the service life of a sewer line and frequently eliminates the need for expensive dig-ups.

Further, VCP’s resistance to a wide variety of acids besides hydrofluoric acid make it a long lasting choice for use in underground sewers.
