METRIC / INCH PIPE DIMENTIONAL COMPARISON TABLES
Nabhan Plast U-PVC pipe systems produses both inch and mwtric system ; tabulated below is a comparison of inch sized pipes and metric sized pipes . Thy are completely different and can only be jointed together by using flanges or adaptors .The systems are also designated differently , the inch system relates to nominal bore; the metric system relates to outside diameter . Both systems are produced with the outside diameter as the controlled diomension .
