A ring seal for pipe sealing is provided to improve air tightness by preventing leakage of gas fundamentally through a sealing protrusion. A ring seal for pipe sealing includes a pair of rings(11). The ring has an assembly gap and a sealing protrusion. The sealing protrusion of the other ring is inserted into the assembly gap of the ring. Each ring forms a cylindrical channel. A front end of an exhaust pipe(12) is inserted into the front end of the other exhaust pipe. Two exhaust pipes are connected each other. |
