Title: Thomas L Pettigrew: Innovator in Pressure Control Technology

Introduction

Thomas L Pettigrew is a notable inventor based in College Station, TX (US). He has made significant contributions to the field of pressure control technology, holding a total of 2 patents. His innovative designs focus on enhancing the efficiency and longevity of hydraulic systems.

Latest Patents

One of his latest patents is the Force Balanced Rotating Pressure Control Device. This invention involves a mechanism that adjusts hydraulic fluid pressure in the upper piston area of a Rotating Pressure Control Device (RPCD). The design features an inner housing that is rotatably engaged within an outer housing by an upper bearing and a lower bearing. The hydraulic fluid pressure is meticulously adjusted to balance the net force in both the upper and lower piston areas. This fluid pressure adjustment creates a force differential that balances the total load transmitted through the bearings, thereby extending the life of the sealing element and bearings. Additionally, a wear indicator is included to signal the end of the useful life of the drill pipe sealing element.
