Never Again that, once buried, the soil would minimize any temperature variations and insulate it from extreme temperatures and variations. But that's not what happened, and so the expected environment was diferent than the actual environment. Although extensive consideration is typically done to evaluate the actual service environment and conditions of any installed coating or lining, other potential environments that the pipe may be exposed to prior to being installed and put into service (i.e., the environment during construction) should be considered. This project and the resulting lining failure provide concrete support that the environment during construction should be a priority consideration. Scheduling and executing any project should include this consideration. Widespread Consequences CoatingsPro's Inaugural Contractors Forum will be one in a mil -ion! Sunday, March 9, 2014 10 a.m. - 5 p.m. Although to the best of this author's knowledge, the extent of cracking and checking was never completely determined to be system-wide, the cause of the observed phenomena was the evacuation of the lining material's plasticizer due to the extended exposure of the lining to extreme elevated temperatures. Exposing some sections of pipe up to 18 months increased the evacuation of the plasticizer in those locations. However, regardless of the outcome, had initial consideration been given to the potential exposure and environmental extremes during construction, adaptation to either the process or the materials could have been made before the problems arose. In addition, this could have prevented the damage to the installed lining film. It just goes to show that when assumptions are made on a construction project, and coatings projects in particular, the consequences can be far reaching. Tere's always a reason behind coatings failures, and mitigating those reasons should be a priority for all. CP Earl C.
