As stipulated in ISO 10508, the lifetime of PE-X pipe is 50 years and longer according to permissible working pressure / temperature.
*NOTE: These pressures are maximum for each temperature level and should not be exceeded.
Pexline PE-X pipe has a recommended maximum long term operating temperature of 90°C and is not recommended for applications where the continuous operating temperature may exceed this limit.
Buteline will not guarantee its PE-X pipe and fittings system where long term operating may exceed 90°C.
Buteline recommends that a suitable pressure limiting valve is installed on the inlet side of the property to ensure water pressure does not exceed pipe pressure limits.
