The E-type hydraulic joint is an improved sealing ball seat, mainly used for temporary sealing at the bottom of the pipe column, to establish the pressure difference inside the oil pipe for the setting of the hydraulic packer. The biggest advantage of this tool is that it reduces the amount of debris falling into the well. After the conventional ball seat is sealed and shot down by the packer, the internal ball seat and steel ball will fall to the bottom of the well, which is not conducive to subsequent deepening operations. If an E-type hydraulic joint is used in combination with soluble balls, it can ensure zero debris falling into the bottom of the well.

Features/Advantages

The shear value of the ball seat can be adjusted before going down the well

After the ball seat is shot down, the ball seat pawl locks, forming a full bore

Normal working pressure 70MPa (10000Psi)

Normal working temperature resistance 177 ℃
