The coefficient of friction between the pulling rope and cable pipe for a high-pressure fluid-filled cable was determined in order to characterize the effects of pulling tension and sidewall pressure on this parameter. Pipe wear was also measured. The study found that variations in pulling tension were more strongly affected by pulling rope wear than pipe wear. The coefficient of friction of the pulling rope varied from 0.27 to 0.75. Pipe wear of 1.52 mm (60 mils) was measured during 430 m (1425 ft.) of pulls at 1414 kgf/m (950 lbs./ft.) sidewall pressure and 1.02 mm (40 mils) of wear was measured during 290 m (950 ft.) of pulls at 610 kgf/m (410 lbs./ft.) sidewall pressure.
