Abstract
The present invention relates to a pipe repair method using a shape-memory alloy that can correspond to pipes of any shape and dimension. The pipe repair method comprises the steps of applying a seal member to a damaged portion of the pipe so as to cover the damaged portion and winding a plate made from a shape-memory alloy that contracts to a memorized shape around a periphery of the pipe so as to cover the seal portion when heated.
