In Memoriam 

Troy Young, vice president and co-owner of Tulsa Rig Iron, passed away in a tragic boating accident over the Memorial Day weekend, in Grove, Okla., at age 48. 

From an early age, he was heavily involved, with his brother Trevor, in the family business. His father, JD Young, first owned and operated Triangle Supplies, (Lafayette, La., and Tulsa, Okla.), which supplied pumps to the offshore oil & gas market. 

Tulsa Rig Iron was established just outside of Tulsa, in 1987, when the HDD equipment technology JD had been instrumental in developing, started gaining traction. 

Originally consisting of several divisions, Tulsa Rig Iron’s early product/services designs were packaged drilling mud recycling systems, triplex mud pumps, and mini-to-maxi-sized HDD drill rigs. During the early 1990s through the early 2000s, Tulsa Rig Iron was a major player in the HDD product market. 

In 2004, JD passed away unexpectedly; Trevor and Troy stepped up at that time as president and vice president, respectively. After a complete business analysis, they decided to shutter the outlying divisions and focus solely on designing and manufacturing world-class mud cleaning systems and triplex mud pumps. 

Since then, the company has grown into a first-class drilling equipment manufacturer, respected and known worldwide. UC
