Summary:Industrial polyolefin piping system with improved stiffness, impact strength for use at high service temperature, comprising single or multilayer pipes, fitting, chambers, valves and vessels, consisting of -nucleated propylene homopolymers with an IR 0.98 having a tensile modulus 1500 MPa, a Charpy impact strength, notched, at +23° C. 30 kJ/m 2 and a Vicat B temperature >90° C. and a Heat Distortion Temperature >100° C. The industrial polyolefin piping system is suitable for chemical plant constructions comprising single or multilayer pipes, fittings, chambers, valves and vessels with improved stiffness, impact strength and high service temperature, preferred for conveyance of natural gas, dangerous liquids and/or toxic liquids.
