TT Technologies recently introduced a pipe rammer and bentonite system package for oil and gas pipeline installation projects. The pipeliner package features an 18-inch diameter Grundoram Goliath pneumatic pipe ramming system and a Grundomudd 500 bentonite mixing/delivery system.
During the ramming process the rammer is attached to the rear of the casing. The tool then drives the pipe through the ground with repeated percussive blows. The Goliath rammer installs steel pipes and casings from 24 to 56 in. 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. Ramming provides accurate installation of casing in a wide range of soil without surface slump, making it ideal for installations under railways and roads.
The pipeliner package is also useful in HDD assist and rescue applications. The rammer can be used to salvage product pipe after a failed bore, install Conductor Barrel casings, remove stuck drill stems and assist drills during product pullback, preventing hydrolock.
