HDD Assist Pipe Ramming Methods

Hdd Assist Using The Grundoram® Pneumatic Pipe Ramming Tool

TT Technologies has developed several pipe ramming techniques to help prevent and salvage failed directional drilling bores. Properly configured Grundoram pipe rammers can be used to salvage product pipe after a failed bore, remove stuck drill stems and assist drills during product pullback, preventing hydrolock.

The Grundoram can also be used to install a conductor barrel casing in order to provide a favorable starting point and friction free pullback section for directional drilling in difficult soil conditions. TT Technologies offers ten models of the Grundoram pneumatic pipe ramming tools.

CONDUCTOR BARREL™
