The invention provides a cooling pipe material with a double-layer structure. The cooling pipe comprises a two-layer structure comprising a layer A and a layer B, the layer A is an outer layer, and the layer B is an inner layer; the layer A is made of flexible modified nylon 12, and the layer B is made of graft modified polyolefin alloy. The cooling pipe and the material have the advantages of hydrolysis resistance, alcoholysis resistance, water vapor permeation resistance, low-temperature impact resistance, stress cracking resistance, simple forming process, small equipment investment and the like.
