Carbon-Zirconium Compound Resin Inner Coat Anti-Corrosion and Wear Resistance Tubing (ZC coated tubing)
ZC coated tubing is coated by a kind of special coating material which is super corrosion prevention and abrasion resisting. Its corrosion prevention and abrasion resisting characters are unique and can be used in water injection wells to prevent corrosion; in eccentric wear wells to prevent abrasion; in submersible electric pump wells to prevent erosion, etc. Its service life is three times to five times longer than those uncoated tubing.
Main advantages
1. Integrating eccentric-well wear proof and corrosion proof as a whole.
a. High effect of anti-wear: its anti-wear effect is improved 3 to 5 times than common one.
b. Corrosion proof: resistance to the corrosion of acid salt and corrosive gases in the produced fluids.
2. Protect both the tubing and the sucker rod.
3. Adaptation to extensional deformation due to the change of well temperature and stress
