Internal joint seal used to replace hole in water supply pipe

Problem

On a project along the U.S.-Mexico border, a contractor damaged a pipeline while drilling into the ground. The drilling caused an 11-inch hole in the pipe that supplied water from the United States to Mexico.

Solution

Miller Pipeline was called to install WEKO-SEALs, its internal joint seal. Once on site, the team conducted its usual safety assessment of the area for precautions it would need to take. As the technicians made their way into the 72-inch pipe, they smoothed the damage inside to ensure the steel-backing band would fit correctly. After fitting the rubber sleeve into place, the technicians secured two 72-inch seals, which expanded to provide a bottle-tight fit. Once the seals were in place, the technicians moved to the outside and applied a concrete mortar around the pipe to complete the patch.

RESULT Within a week of getting the call, the team had sealed the pipeline, saving many communities from water service disruption. 800-428-3742; www.millerpipeline.com 


Blade a fit for drilling in rocky conditions

Problem

Directional Trace LLC is a contractor based out of Thornton, Colorado, that has been working on production work for a fiber company in Fort Collins, Colorado, at the base of the Rocky Mountains. The conditions make for challenging HDD jobs with the varied types of ground conditions drillers are faced with.

Solution

On Sept. 18, 2019, Directional Trace LLC decided to test out Melfred Borzall’s Red Diamond Blade with the included Pit Bull Design features. This specific blade comes with more than twice as many carbides as the standard blade, and is specifically designed to hold up to varied, hard ground conditions in which a steer face blade is appropriate without switching to a hard ground bit. The Pit Bull feature utilizes engineered dowel pins that minimize the possibility of bolts getting sheared off since the solid dowels are taking the load instead of the bolts. It also helps guard against those same bolts rattling loose and losing the blade or product downhole. 

RESULT Drilling with a 5 1/2-inch blade on a Vermeer 2330 Rig, the contractor drilled in the rocky soil conditions at the base of the Rocky Mountains with his Red Diamond Blade for over a year with the same blade. Only after 14 months did he finally return to HDD Parts Plus of the Rockies, the local Melfred Borzall tooling distributor, for a replacement. 800-558-7500; www.melfredborzall.com
