Heavy-load hydraulic safety coupling

Heavy-load hydraulic safety coupling

                   1.     Introduction

Heavy-load hydraulic safety coupling use lock key connection, it can hold hightension and torque. When needing to disconnect the safety coupling, the use can drop ball to the piston seat. Adding pressure to cut the shearing, piston down, lift column and safety coupling disconnect with clear indication. On the upper neck of downhole tool, there is a standard designed “GS” for fishing.
