Insitu impedance heating for pipe wall repair

摘要

The apparatus and method for insitu repair of pipes and conduits of varying diameter is taught by the specification and drawings. The invention utilizes impedance heating techniques and devices that previously been used to heat the contents within pipes and tanks. The invention can be adapted to utilize AC circuit components place either within the interior diameter of the pipe or adjacent to the outer pipe surface. The apparatus and method can include use of thermal couples or other components to monitor temperature and control electric current. The device and method can be variably used with electrical isolation components and techniques.
