    摘要: A method of repairing a pipe at the joint of existing gas pipes, wherein the joint of existing gas pipes is repaired by means of a repairing apparatus to be moved under remote control in the gas pipe, and the repairing apparatus can be put into or taken out of the gas pipe through a working hole formed on the upper part of the gas pipe by drilling means while gas is kept flowing without danger of leakage thereof, whereby the trouble of forming a working hole at the start of repairing operation and restoring the hole to the initial state at the end of the operation can be simplified to reduce time and expense for the repairing operation.
