<p>The invention relates to a pressurized fluid conduit made from a semi-crystalline thermoplastic material that has a hardness of between 50 and 65 Shore D and a modulus at 150 DEG C of at least 60 MPa. Advantages of such a conduit are easy handling and assembling at for example room temperature, while still requirements regarding burst-pressure and deformation at elevated operating temperatures are fulfilled. Other important advantages include significant savings in material use and better vibration and noise damping. The invention also concerns use of a semi-crystalline thermoplastic material with a hardness of between 50 and 65 Shore D and a modulus at 150 DEG C of at least 60 MPa for making a pressurized fluid conduit via an extrusion moulding process, and a process for making said conduit.</p> |
