CPVC pipe in diameters in the range from 15 mm (0.5 inch) to 15.24 cm (6 ins), to carry hot and cold aqueous streams under 690 KPa (100 psi) pressure and 82.2°C (180°F) in continuous service, is extruded from a compound in which the CPVC has a high CI content in range from 66.5%-70%, when modified with either of two specific impact high rubber modifiers in an amount greater than 5 parts but no more than 6 parts per 100 parts of CPVC. Extruded CPVC pipe provides a HDB measured according to ASTM D2837-01 which is 25% or more greater than that required for commercial pipe as specified in ASTM D2846. As a result, both SDR-11 and SDR-13.5 pipe are produced which provide a HDB greater than 1250 psi (8.62 MPa) at the 100,000 hr intercept.

L'invention concerne un tube en CPVC pouvant avoir un diamètre dans la plage de 15 mm (0,5 pouce) à 15,24 cm (6 pouces), pour transporter des courants aqueux froids et chauds à une pression de 690 KPa (100 psi) et à une température de 82,2 °C (180 °F) de manière continue, qui est extrudé à partir d'un composé dans lequel le CPVC a une teneur élevée en CI dans la plage de 66,5 % à 70 %, lorsqu'il est modifié avec l'un quelconque parmi deux modificateurs d'impact spécifiques à teneur élevée en caoutchouc en une quantité supérieure à 5 parties, mais inférieure à 6 parties pour 100 parties de CPVC. Le tube en CPVC extrudé fournit une HDB mesurée selon la norme ASTM D2837-01 qui est supérieure de 25 % ou plus à ce qui est requis pour un tube du commerce tel que décrit par la norme ASTM D2846. Par conséquent, les tubes SDR-11 et SDR-13.5 qui sont produits fournissent une HDB supérieure à 1 250 psi (8,62 MPa) lorsqu'ils atteignent 100 000 heures.
