Cured-in-Place Pipe (CIPP) rehabilitation is a realistic and cost-efficient alternative to extend the life of existing sewer lines. This procedure offers rehabilitation for pipes without the need to dig into the existing pipeline.
Plastics don’t respond in the same manner with metals. Even when stressed below their yield stress, plastic materials will creep and given sufficient time under load plastics can fail. It’s critical to understand this creep characteristic when designing a CIPP liner installation.
Since the CIPP industry is now effectively a global supply chain, it’s useful to examine the differences between ASTM F1218 and ISO 11296 to determine how CIPP flexural properties measured by the North American testing method compares with flexural results determined by the international method.
The Job Is Not Finished Until The Paperwork Is Done. So, your crew has just completed your latest CIPP installation. Even though cured-in-place-pipe has become a routine rehabilitation technology for underground sewer and water infrastructure, many CIPP installations can still present unique challenges. This last installation was full of those “unique” challenges. Not only was[…]
Vibration Testing – Where Should You Mount The Control Accelerometer? When you contract a vibration testing services laboratory what you’re really doing is hiring someone to input a precise amount of energy into your DUT in a way that can be repeated. In order to do this the laboratory requires a detailed test method and[…]
