The present disclosure relates to a crosslinked polyethylene pipe having excellent physical properties. The crosslinked polyethylene pipe according to the present disclosure has optimized the degree of crosslinking and storage modulus by finding out the optimum physical property range between the degree of crosslinking and the storage modulus which have a mutual trade-off relationship, whereby the crosslinked polyethylene pipe according to the present disclosure has excellent long-term durability and short-term pressure resistance, and thus can be applied to various fields requiring these physical properties.
