20140251637 | Gripping Dies for Continuous Coiled Rod Injectors and Fabrication and Use Methods Relating to Same - Gripper dies for a continuous coiled rod injector are machined from a single, unitary, integral steel body forming both the base portion for connection to the injector drive chain and the gripping portion for engagement of the continuous coiled rod. Lower skate pressure is required relative to conventional aluminum dies, increasing the lifespan of injector components while providing improved performance and avoiding damage to the coiled rod by use of alternating grooves and ridges in the gripping face of the die and smoothly radiused transitions the ends thereof. | 09-11-2014 |
