Effective Runner Heights and Lengths – G and GN
Sizing carrier pipe O.D. and casing I.D. can be misleading at times due to a difference between nominal and effective dimensions. When sizing, make sure to consider effective runner height. Two heights are available/used; custom positioning in the casing can be achieved with riser heights.
Heights – Nominal Versus Effective
2″ Wide Glass Reinforced Nylon or Polyester Runners
Nominal = 1.0″ (25.4mm) – 1.5″ (38.1mm)
Effective = 1.07″ (27.2mm) – 1.70″ (43.2mm)
Lengths – Effective 2″ Wide Glass Reinforced Nylon or Polyester runners
7.0″ (177.8mm) – 11.0″ (279.4mm)
Glass reinforced polymer runners are standard in 2″ (50.8mm) widths for Model C (coated). PSI GN glass reinforced nylon runners have 5 times the compressive strengthof polyethylene runners. Our Model G polyester 2″ wide runners are particularly designed for heavier pipes and longer pulls.
