The PolyOil Poly-WearJoint™ is a safe, efficient and cost-effective riser deflector system that ensures that rig diversions systems conform around the umbilical or auxiliary lines on the outside of the landing string and prevents the dangers of expanding pockets of gas kicks. The WearJoint™ is an interlocking modular stacking system that resists pressures and increases safety on drilling rigs during completion and workover operations.
