What is NM-EPC?

Non-Metallic – Engineering, Procurement & Construction

Complete EPC projects with corrosion-free infrastructure

NM-EPC is the integral execution of industrial infrastructure projects using exclusively non-metallic materials (RTP pipes, HDPE, polymeric systems) that eliminate electrochemical corrosion and MIC deterioration.

Unlike traditional carbon steel EPC, our approach guarantees assets with 50+ years of service life, zero derating, reduced CAPEX by up to 40%, and zero maintenance due to internal corrosion.

CAPEX reduction

Key differentiators vs. traditional EPC

Zero internal corrosion: elimination of losses due to MIC and electrochemical attack
Accelerated installation: flexible systems, reduced welding and fitting requirements
Superior chemical resistance: compatibility with H₂S, CO₂, brines, and acidic fluids
Lower environmental footprint: no cathodic protection, less excavation, reduced transported weight
