Michels uses Direct Pipe method for installation at U.S.-Mexico border
Michels added to its string of successes using the Direct Pipe® method by installing a 48-inch gas pipe under the Rio Grande River and the border between the United States and Mexico.
The 2,460-foot installation spanned from Starr County, Texas, to Tamaulipas State, Mexico, in one continuous pipe string. The vast majority of the work was done from the Texas side, making Direct Pipe® an ideal method for an international border project, said Matt Smith, Direct Pipe Manager.
The Direct Pipe® method was selected at the site because the process is done with the pipe string and installation operations on the same side. Additionally, geotechnical ground conditions comprised of sand, silt, clay and claystone that were not ideal for horizontal directional drilling (HDD) on an international border crossings, the Direct Pipe® method minimized potential for the inadvertent release of drilling fluid into the Rio Grande River, which would have been difficult to manage with HDD due to access issues.
The project was completed in less than two weeks.
