Oil pipe 346 series

transportdouble-walled

by adding an outer layer of pipe to the outside of the single-layer pipe, the damage of the single-layer pipe can be avoided, and the possibility of seepage prevention can be enhanced too; • created the clearance space between the inside and outside pipelines, and the leakage monitoring system can be used to monitor the clearance space to check the leakage situation; • both inside and outside layer of the pipe inner contain EVOH resin lining, double wall pipe with double leakage performance guarantee; • inner surface of the pipe conducting electrostatic layer resistance: 1.8ｘ1014 Ω • suitable for self-priming and pressure piping systems;
