DCD Design and Gemini Machine Works have partnered to designed, built, and field test a revolutionary hex slide (locking) flow through swivel which can accompany all ranges of swivels from 20 Ton to 500 Ton.
This locking – flow through swivel can be utilized in a variety of applications for HDD Drilling; however, we’ve found one of the most common usages is the exit side crossings whereby a larger rig is on the entrance of the hole and there is a smaller rig on the exit side of the hole which is assisting / pushing the pipe through the hole crossing. This locking – flow through swivel helps rotate and pushes mud through as the hole is being reamed.
DCD & Gemini Partnership
To date, we’ve undertaken these flow through swivel designs for 220 Ton, 110 Ton and 80 Ton swivels.
