For the installation of casing in a wide range of soil without surface slump, a new pipe rammer and bentonite system package from TT Technologies is suited to oil and gas pipeline placement under railways and roads. The package includes an 18-inch-diameter Grundoram Goliath pneumatic pipe ramming systems and a Grundomudd 500 bentonite mixing/delivery system. During the ramming process, the rammer is attached to the rear of the casing, and the tool drives the pipe through the ground with repeated percussive blows. The Goliath rammer installs steel pipes and casings from 24 to 56 inches in diameter. The rammer can also be used for the slick-bore process, installing a bore pipe which, when removed, pulls the product pipe into place.
