LORD^® Telescopic Joint (or Slip Joint) Packers

LORD has deep expertise in rubber-to-metal bonding. We employ strict process and quality controls to ensure that each part is manufactured consistently, with a strong bond. This attention to detail coupled with our elastomeric formulation capabilities is what makes LORD TJ packers so reliable. With more reliable seals, you can drill longer without interruption, allowing you to drill multiple wells on just one set of TJ packers.

Features and Benefits

Field-proven: wear-resistant nitriles outlast the standard nitriles employed in many TJ packers today
Low actuation pressure enables operating primary packer on rig air supply
Compatible with water: retains 90% of tensile strength in swell testing, compared to only 10-15% for polyurethanes
Improved quality via our manufacturing techniques, process control, and rigorous quality standards
Stable, reliable bonds
Our hyperelastic FEA modeling optimizes design
Inner and outer packers stocked for all OEM riser styles for quick turnaround
12-month in-service warranty

API 16F Certified

LORD wear-resistant TJ packers have passed the rigorous requirements of the second edition of API 16F. During the abrasive 50,000 cycle wear test, LORD packers lost less than 0.75% elastomer mass, representing more than a 13x margin to the 10% pass/fail criteria in Standard 16F.

Abrasion Comparison Chart with Wear-Resistant Nitrile

Laboratory and field-tests have confirmed that our wear-resistant TJ packers last longer than the standard nitrile packers used in many slip joints today. In abbreviated wear testing to 6,300 of the 50,000 cycles specified in Standard API 16F, our packer had no measurable wear, whereas a standard packer lost 7% of its thickness. Field-test results demonstrated that the wear-resistant TJ packer lasted 20 times longer than a standard TJ packer. The table below presents a summary of the full-scale test data.
