Specifications
1.API 5CT HDPE casing and tubing 2. Anti-abrasion &Anti- corrosion 3.2-3/8"~4-1/2"(60.3mm-114.3mm) 4.HDPE liner reduces the friction coefficient between sucker rod and tubing. After adopting HDPE liner, the non-failure operational time related to the abrasion and corrosion between sucker rod and tubing increases by 400%. Under condition of not changing other design parameters, some of operational parameters, such as the load of sucker rod, balancing torque, Min stress of the bottom sucker rod string reduce greatly. The annual well operation frequency reduces from 4.3 to 0.59 after adopting the product.
Because of the low friction coefficient between HDPE liner and sucker rod, not only the polished rod load, gear reducer’s output torque and Min. stress of bottom sucker rod string reduce greatly, but also the difference between maximum and minimum road of polished rod decreases obviously. The HDPE liner tubing reduces the energy consumption and increases the fatigue lifespan of sucker rod string obviously.
Corrosion, erosion, scale, rod wear, fatigue, pitting, embrittlement, all resulting from the very demanding environments downhole tubulars are subject to in todays energy industry. Check out our lined tubing proven solution.
Protecting your tubing investment | HDPE Advantages |

Superior chemical and corrosion resistance 3.Very effective in used tubular 4.Mechanically bonded 5.Erosion resistant 6.Very tough, yet flexible 7.Non ionic bonding surface |
HDPE tubing applications
1. PCP or rod pumping oil wells
2. Injection and disposal wells
3. Slant, deviated, or directional wellbore tubing strings
4. Chemical injection strings
Why HDPE Tubing Should be your only choice for water injection or disposal well applications
1. It is a barrier that is mechanically inserted inside the tubing joint.
2. The liner will not flake, crack, chip, or come off. Your tubing string will always be internally protected, top to bottom.
3. Liner is unaffected by turbulent flow.
4. HDPE has 10 times the erosion capabilities of bare steel.
5. Liner is compatible with all stimulation fluids.
6. Lined string can be used as work string.
7. Tubing joints with liner inserted are virtually rig proof and will not be easily damaged while tripping.
