This was the first week that Tampa Bay Plumbers has ever had all of its lining systems being used all day, every day performing pipe lining in Tampa. Tampa Bay Plumbers puts in more pipe lining (CIPP) in Tampa than any other contractor in this area. We are currently installing over 2500 feet at various projects around the Tampa Bay area. We have two methods of curing liners that we use on a regular basis. The most common method for small pipe lining projects is an ambient cure process. For larger pipe we prefer to use a steam cure process. The steam cure process uses a different resin which is heat activated in order to cure. The ambient cure process will begin to cure the moment the A and B resins are mixed together. You must select the proper method based on the project. In the picture shown, we have just inverted the calibration tube inside of the liner using an air inversion system.
