Global green hydrogen storage and transportation infrastructure construction surges in 2026. High-pressure hydrogen steel tubes face fatal hydrogen embrittlement risk: tiny hydrogen molecules penetrate ordinary coatings and steel substrates, causing internal cracking and major safety hazards. Traditional single epoxy lining cannot block micro hydrogen penetration, failing long-cycle hydrogen transmission operation.

FLDC independently develops graphene modified multi-layer anti-hydrogen embrittlement coating system exclusively for high-pressure hydrogen storage & delivery steel pipes:

1. Graphene modified epoxy zinc phosphate primer: Enhance substrate adhesion & compact barrier foundation
2. High-density graphene thick-film intermediate layer: Block micro hydrogen molecule infiltration path
3. Epoxy phenolic inner lining topcoat: Ultra-dense anti-hydrogen medium finish Core Advantages: ✅ Unique graphene dense film structure, effectively isolate hydrogen penetration to avoid embrittlement ✅ Stable performance under 70MPa long-term high-pressure hydrogen working condition ✅ Resist hydrogen-rich wastewater & acidic condensate long-term soaking ✅ Pass hydrogen medium aging & pressure impact certification ✅ Low odor solvent-free formula for confined pipe construction Our hydrogen storage pipe coating has been supplied to green hydrogen EPC companies across Europe & Southeast Asia.
