For the underground piping network at PTTEP Bangkok Phase 3, Denso corrosion protection products were applied, including Denso S105 Paste (2.5 kg/tub), Densyl Tape (100 mm x 10 m), and Densocovercoat Tape (100 mm x 10 m). These materials form a comprehensive protective wrapping system designed to prevent corrosion and water ingress in buried steel pipelines.

The Denso system ensures long-term integrity of the pipe network, especially in moist or corrosive soil conditions, helping maintain reliability and reducing future maintenance requirements.
