PP‑R, PP‑RCT wykazują bardzo wysoką odporność na tem-peraturę. Przy stałym obciążeniu temperaturą 70°C eks-trapolowana trwałość rur PP‑R wynosi 50 lat. PP‑RCT jest materiałem o jeszcze lepszych właściwosciach wytrzymało-ściowych niz PP‑R. Szczegółowe informacje o odporności
Temperature Range. PP-H: –5oC to 90oC (23oF to 194oF) PP-R: –20oC to 90oC. Polypropylene is a member of the polyolefin family and is used in a wide variety of applications from acids and alkalies to organic solvents and even pure water.
Before you start installing Pestan PP-R and PPR-CT pipes and fittings for the transport of fluids under pressure both in the household and in the industrial sector apply,
The MECHANICAL pipe system made of PP-R offers a non-corroding and long-standing solution for conveying water in enclosed cooling water systems for residential and commercial buildings, such as hotels
at the operating temperature of 60 °C, 10 years at the operating temperature of 80 °C, 1 year at the operating temperature 90 °C). Maximum operating pressure (4, 6, 8, 10 bar) corresponding to the application class is calcu-lated and assigned for each material and pipe series S. The Aluminium Foiled pipes are three-layer pipes: the inner ...
In general polypropylene can be used at temperatures from 0°C to +80°C, Beta-PP-H in the range from −10°C up to 95°C. Below −10°C, the outstanding impact strength of the material is reduced. On the other hand, the stiffness is even higher at low temperatures. Please consult
PP-R has a very good long-term creep strength at higher temperatures, such as, for example, 80°C at continuous stress . Unlike PE, PP is not as impact-resistant below 0°C . Because of this, GF recommends ABS or PE for low temperature applications . The long-term behavior for internal pressure resistance is
