Mo-Slip Ball Joint Liner

Category:

Pipeline/Discharge Systems

Description:

Elevated discharge pressures in floating pipelines can cause the torque required to deflect the ball

joint to exceed that allowable bending strength of the pipe. Friction-reducing ball-joint liner

reduces bending stress on the pipe, which in turn reduces the torque required to deflect the ball

joint.

Mobile Pulley and Machine Works, Inc. has developed the Mo-Slip ball joint in order to decrease

the friction between the ball and gland. The joint is made of urethane type material, a

low-friction, low-creep, high-compressive-strength material.
