The invention discloses a pipe fitting for natural gas transport, and relates to the technical field of pipe fittings. The pipe fitting at least comprises a pipe body; a dust collection hole penetrating through the inner pipe wall and the outer pipe wall is formed in the pipe body; the outer side of the pipe collection hole is provided with a detachable sealing cover matched with the dust collection hole in a sealed mode; the inner wall of the pipe body is provided with a guide convex ring in the circumferential direction; and the guide convex ring is located on the side of the pipe inner opening of the dust collection hole, and the wall of the side, facing towards the dust collection hole, of the guide convex ring is provided with an annular guide groove. In order to solve the problem that a pipe valve leaks due to the fact that dust particles in a natural gas pipeline network are prone to scratching the inner wall of the pipe valve, the pipe fitting which is used for natural gas transport, capable of collecting and removing dust particles in the pipe and reducing pipe valve leakage risk is provided.
