The National Clay Pipe Institute www.ncpi.org is the single center for the research and development of clay pipe technology. As a result of this focus and decades of research and development, we have become the authority when it comes to Vitrified Clay Pipe. We are available to provide assistance in design, training and evaluation of systems. Forensic analysis can also be performed if necessary. As an organization we are responsible for the development of leak free, factory applied compression joints and the air pressure test to verify the performance of those joints. We defined and characterized specific methods and practices for placing pipe to insure the longest service life of any available material. In the twenty-first century, The National Clay Pipe Institute is an unsurpassed technical resource offering educational seminars on a variety of subjects (with CEUs available depending on local regulations). We continue our strong tradition of scholarly research by partnering with universities and municipalities in field research projects designed to answer specific concerns.
