PROBLEM TO BE SOLVED: To provide a multilayer pipe having pressure resistance and suitable for piping.SOLUTION: A multilayer pipe 100 comprises at least a first layer 110, a second layer 120 and a third layer 130 from the axial center to the periphery. The first layer 110 and the third layer 130 are resin layers predominantly composed of polyolefin resin. The second layer 120 is a fiber-reinforced resin layer that comprises an alignment layer comprising polyolefin resin and glass fiber and the glass fiber is aligned along the periphery of the first layer 110.SELECTED DRAWING: Figure 2 |
