Abstract:
1. A vertical pipe lining method comprising: a. positioning a tubular shaped repair material having a first end and a second end by pulling the repair material into a substantially vertical oriented pipe from a first pipe opening through the pipe to a second pipe opening where one pipe opening is a bottom opening relative to the other top opening and the repair material comprises a multi-layered lining of a first outer layer comprising a thermally responsive component and an air impermeable second inner layer; b. inflating the repair material by adding air to the repair material to press the first outer layer of the repair material against the pipe; c. conveying heated air through the inflated repair material from the bottom opening to the top opening to cure or mold a thermal responsive component of the repair material to the pipe; and d. constricting the second end of the repair material by placing an air pressure regulating valve and the second end of the repair material traverses from the first pipe end to the upper second pipe end.
