Approach to the Choice of Polymer Material of a Drill Pipe Protector

Abstract:

The drilling conditions are becoming more severe, which leads to the need to select new polymeric materials that can withstand heavy loads, provide a longer resource and are more resistant to high temperatures. To solve the problem, a set of laboratory tests on standard and specialized tribological equipment is proposed. The friction force, wear resistance under various conditions and according to various criteria, hardness at normal and elevated temperatures, thermal field during tests, change in the roughness of a steel counterbody as a result of tests are evaluated. Wear resistance is determined using a PBD-40 friction machine. Samples are cylindrical bodies with a diameter of (5.0 ± 0.5) mm, a height of 10.0 mm from the materials under study. The samples are fixed in the designed fixture. As a result of the tests, the average values ​​of the parameters for the investigated materials were determined, and the effects arising from friction were noted. The criteria for choosing a material have been formulated and the most suitable material for the tread has been selected.
