Abstract

This paper presents the results of an experimental study conducted to determine friction coefficient of J-55 tubing with eight different compounds. Four of the compounds meet the specifications of API Modified, and four were lead-free. The specimens were machined and phosphatized with manganese phosphate. The surface roughness of the specimens was nominally 1.27 micron. Repeated tests were run at a rotational speed of 1.5 rpm and 5 rpm. In each test the bearing load was increased monotonically to a maximum of 625 kN. Friction coefficient data obtained during the tests are presented and discussed.
