Can the butt weld on HDPE pipe, or on HDPE pipe fittings when the system works at high pressure - for example PN20, withstand?

    • Each type of pipe and pipe fitting has a specific working pressure rating. In a system, if pipes and pipe fittings have different working pressure values, the working pressure of the entire system will be the minimum pressure value of the pipe section or pipe fitting.
    • For example: If a pipe has a working pressure of PN10 while the pipe fitting has a working pressure of PN20, the working pressure of the system will only be PN10.
    • The butt welds on that system, if properly performed, will also withstand the corresponding working pressure.
