1960

WIRE LINE DRILL ROD DESIGN

In the early 1960s, Ake Ronnkvist innovated and progressed both the design and process to manufacture quality down-hole tools. It all started with the Wire Line Drill Rod Design.

FIRST INERTIA WELDED DRILL PIPE

INERTIA WELDED SUCKER ROD

In the 1980s, we designed the Inertia Welded Sucker Rod for the Oil and Gas Industry.

INNOVATED HORIZONTAL DIRECTIONAL DRILL PIPE DESIGN

In the 1990s, we innovated many of the Horizontal Directional Drilling Drill Pipe designs that are still in use today.

2000

FIRST HELICAL PATENT

In the early 2000s, we began the design and then patented the strongest pound-for-pound helical pier in the world.

2010

CHILEAN MINE RESCUE

In 2010, we engineered, developed and manufactured the Drill String that was used in the Chilean Mine Rescue. The pipe that we designed was carefully chosen to advance the boring utilized to form the rescue shaft for the miners that were trapped in the San Jose Mine. “After being trapped under ground for months, a dramatic rescue mission unfolded live on TV sets across the globe: 33 miners were pulled from the Earth alive and reunited with their families, 69 days after they were trapped.” – USA Today
