Polycore Thermoplastic Lined Tubing “Give Us Your Worst Well!”

Polycore Tubular Linings provides thermoplastic liners that have been proven in down-hole applications in over 18,000 wells during the past 15 years. Operators experience drastic reductions in operating cost by eliminating rod on-tubing wear and corrosion failures. Savings can also be found with: less work-overs, prolonged tubing life, minimized lost production, reduced energy required for lifting in pumped wells, and reduced need for corrosion inhibitors. Thermoplastic liners are extremely abrasion resistant and chemically inert, eliminating concerns associated with wireline damage, coil tubing mechanical damage, acid treatments, and chemical treatments.

Polycore’s patented products have been particularly effective in eliminating rod on tubing wear in beam pumped wells, progressive cavity pumped wells, and any well associated with deviations. Thermoplastic liners are also effective with other artificial lift methods such as plunger lift wells, submersible pumped wells, and gas lift wells. Use of this technology eliminates the need for tubing/rod rotators as well as rod guides and/or special rod boxes.

Thermoplastic liners have also been proven effective in reducing corrosion failures in injection wells, disposal wells, and flow lines.

This mechanically bonded liner solution allows you to recognize additional savings by promoting the use of used inspected tubing including: yellowband, blueband, and greenband. The Polycore liner installation process also allows reusing tubing already internally coated with plastic or epoxy, without incurring the cost of having the old internal coating removed.

Thermoplastic liners can also be installed in used tubing which may previously have been scrapped due to pin thread mechanical damage or corrosion damage caused by chipped coatings. With sufficient upset remaining, the threads can be repaired and a thermoplastic liner installed.

Polycore’s unique and innovative end finishing process, in combination with a coupling internally coated in the J-area, ensures zero corrosion through the entire string of tubing while maximizing the ease of running tubing in the field. No corrosion barrier donuts/inserts, special torque make-up requirements, or service technicians are required. Polycore lined tubing is run using a torque to optimum API specifications.
