5" round mandrel slip joint

Round mandrel slip joint is specifically designed for floating vessel operations( such as squeezing, treating, etc.) Its purpose is to provide an expansion joint in the string to help compensate for the up and down movement of floating drilling vessel. It is also used to compensate the contraction and expansion caused by the temperature and pressure change on land test.

Size: 3 7/8" & 5"

Working pressure: 10000 psi & 15000psi

Working condition: Above 175oF H2S and Full H2S

The round mandrel slip joint, like other slip joints, accepts the movement associated with ocean heave or temperature change without allowing the movement to disturb the placement of downhole tools.

The round mandrel slip joint has the following characteristics:

• Top of the mandrel slip joint has 4 3/4-in. (120.65-mm) drill collar profile for easy handling with the rig elevators and slips

• Maintains its full tensile rating when collapsed and locked

• Can be locked in the closed position for handling, reducing the risk of damage to the lifting/sealing mandrel

• Internally pressure and volume balanced

• String can be picked up with the slip joint locked; the slip joint can then be unlocked before it is run into the hole

• Provides free travel in the string to reciprocate tools without unseating the packer
