The present invention provides air conditioning piping for a vehicle. The air conditioning piping for a vehicle includes: a first pipe which is formed with an insertion groove on the outer circumferential surface; and a second pipe which is inserted into the insertion groove. The second pipe includes: a body unit; a first protrusion unit which is formed at a lower part of the body unit and is inserted into the insertion groove; and a second protrusion unit which is formed between the body unit and the first protrusion unit and has a lower surface formed to be curved to cover the outer circumferential surface of the first pipe. According to the air conditioning piping for the vehicle of the present invention, the purpose of the present invention is to provide the air conditioning piping for the vehicle having a structure, in which the first protrusion unit is, firstly, easily inserted and fixed to a pipe to be welded during pipe welding and which can be easily welded by the second protrusion unit, by forming the first protrusion unit and the second protrusion unit through first and second forming of pipes of a source material.
