The invention provides a metal pipe airtightness detection device which comprises a feeding device, a to-be-detected metal pipe is placed and conveyed on the feeding device, a pneumatic valve is arranged at one end of the top of the feeding device, a test platform is arranged on the side, close to the pneumatic valve, of the feeding device, and a sliding way is arranged between the feeding device and the test platform. A plurality of pipe limiting grooves are formed in the test platform at intervals, a to-be-tested metal pipe enters the pipe limiting grooves in the test platform through a sliding way, a high-pressure gas pipe and a horizontal guide rail are arranged at the two ends of each pipe limiting groove respectively, and a first air cylinder is arranged at the end, away from the pipe limiting grooves, of the horizontal guide rail. After the to-be-tested metal pipe enters the pipe limiting groove, the pressing device presses the to-be-tested metal pipe, the first air cylinder pushes the clamping pin to
