PURPOSE: An apparatus for detecting the noise and a crevice in a gas pipe is provided to prevent the accident by installing a pressure gauge at one side of an outer pipe and a gas injection port at the other side of the outer pipe. CONSTITUTION: An apparatus for detecting the noise and a crevice includes a reinforcement member(32) which is arranged at a peripheral portion of an inner pipe(31) with a constant interval. At least two perforation holes(33) are formed in the reinforcement member(32). An outer pipe(34) is installed at an outer portion of the reinforcement member(32). A rib(39) is installed at the reinforcement member(32) so as to securely fix an end of the outer pipe(34) to the rib(39). A flange is formed at the end of the outer pipe(34). A pressure gauge(36) is installed at one side of the outer pipe(34), and a gas injection port(37) having a valve is installed at the other side of the outer pipe(34).
