NHM’s patented breakout system requires no tongs or wrenches. NHM has two patents on its locking swivel design.Įstablished in 1979, North Houston Machine, Tomball, Texas, has a fully-equipped machine shop with precision weld and fabrication facilities and specializes in custom-design products such as rotary heads, swivels, side feed and conventional swivels for air, water or mud drilling, and designs and manufactures drill pipe and tool joints for water and seismic drilling. Mannen said other companies also have locking swivels, but the locking/unlocking process in not as simple. Pull swivels are in our catalog, and we have featured it at trade shows. Word has spread through the industry about the benefits of free spooling for intersects. “A superintendent at Direct Horizontal Drilling told me they have been using them in “intersecting” applications for at least five years. “We have been making locking pull swivels for over 15 years,” Mannen said. It’s not clear how long free spooling has been employed with intersects. There are four socket head cap screws to loosen, slide the locking ring over the mating hex, tighten the bolts, and the swivel will be in the “locked position”. Designed specifically for directional drilling, the Condux 400 D.Drill Swivels prevent boring equipments rotational torque from interfering. Mannen said changing the swivel from “free spool” to “locked” is simple. And ‘free spooling’ helps eliminate unnecessary stress on the equipment which allows machinery and tools to last longer.” “The benefit of being able to lock the swivel creates a safer and more efficient way to begin removing the pipe. When it comes time to breakout the pipe, the swivel can be switched to the lock position. “With two rigs placed at each side of the bore, the swivel is used on the pull side or exit side to allow fluid to pass through and rotate freely. Petroleum Engineer Focused on O&G Production and Drilling. “We designed the swivel to rotate freely to allow fluid to pass through, or to lock, stopping rotation,” said North Houston Machine (NHN) owner Mike Mannen. In its product line is an HDD locking swivel. The story begins at North Houston Machine Inc., a company offering downhole products for multiple types of drilling operations, including horizontal directional drilling (HDD). Several years ago, a driller discovered that a simple locking swivel could simplify intersects.
