The invention relates to the technical field of stainless steel pipe fittings, in particular to an annular clamping type anti-frozen-off stainless steel pipe fitting. The stainless steel pipe fittingcomprises a connector and a connecting pipe; the connector comprises a limiting ring, a first inner clamping ring, a second inner clamping ring and an outer clamping ring; the connecting pipe comprises a circulating end, outlet ends and a connecting end; the number of the outlet ends is 2; and the connecting end is welded to the connector. According to the stainless steel pipe fitting, the secondinner clamping ring provides buffer space for the connecting pipe which is inserted into the connector, so that the difficulty of inserting the connecting pipe is lowered, and welding is easy; the first inner clamping ring and the second inner clamping ring provide buffer space for the connector for contracting inwards, and the outer clamping ring provides a buffer space for the connecting pipe for expanding outwards, so that the connector and the connecting pipe are prevented from being frozen off; and the connecting effect and the sealing performance between the connecting pipe and the connector are more stable and reliable, the connecting pipe can enter the connector more easily, the welding difficulty is lowered, and the connector is prevented from being frozen off.
