PROBLEM TO BE SOLVED: To provide a polypropylene pipe having a high rigidity. SOLUTION: This polypropylene pipe is produced by the thermal forming of a polypropylene containing 0-6mol% of a constituent unit derived from a 4-20Cα-olefin and having a melt flow rate of 0.005-5g/10min under 2.16kg load at 230 deg.C, the maximum peak temperature on an endothermic curve of 128-172 deg.C determined by a differential scanning calorimeter, a density of 898-917kg/m<3> and a flexural elastic modulus of 800-2,600Mpa measured on a pressed sheet test piece molded at 200 deg.C. |
