Reliability Evaluation for Improved Screw Dies of Coiled Tubing unit Injector
Journal Title: Tribology in Industry - Year 2017, Vol 39, Issue 1
Abstract
The paper considers improvement of screw dies of mobile coiled tubing unit injector through the change in screw die's design parameters with further mounting of metal-ceramic based friction material. Comparison of designs of unit injector screw dies was carried out and reliability evaluation of an improved coiled tubing transporter unit was executed.
