Drawbacks of Conventional Piping

a. Seamless steel pipe (conventional pipeline) has rough inner walls. Joints are welded or threaded, which not only easily causes pressure drop and joint leakage, but also renders damaged areas susceptible to corrosion. Over time, corrosion reduces the inner diameter, resulting in higher pressure drop and increased leakage.

b. Both inner and outer surfaces of seamless steel pipes are prone to corrosion, especially under acidic or alkaline conditions, as well as at local damaged spots and joints.

Corrosion Resistance of Energy‑saving Piping

a. The inner surface of the energy‑saving piping system is treated by anodization, forming an extremely smooth and dense Al₂O₃ protective layer. The outer surface is finished with special powder‑coating material (gloss finish of piping reaches MO grade), providing permanent corrosion resistance for both inner and outer walls with excellent acid and alkali resistance.

b. The inner wall of the air‑piping system is smooth. No pipe shrinkage occurs at connections between pipe sections, so pressure drop remains very low. Special connection sealing combined with corrosion‑free piping eliminates leakage. Thanks to these characteristics, pressure loss of the PeAir piping system will not degrade over time.
