U3 Hytraxon-GAS – Integrated Solution for Hydrogen Pipeline Construction, Investment & Operation
U3 Hytraxon-GAS: An Integrated Solution for Long-Distance Hydrogen Pipeline Transportation
Ensuring Safe and Efficient Delivery of Pure or Blended Hydrogen — From Materials to Control, from Construction to Operation
1. Core Capabilities Overview
U3 Hytraxon-GAS delivers an integrated “Materials–Equipment–Control–Engineering–Investment” solution for hydrogen pipeline systems, applicable to:
Pure hydrogen trunkline networks (e.g., green hydrogen hubs → industrial clusters)
Retrofitting of natural gas pipelines for hydrogen blending (up to 20% H₂ by volume)
Internal hydrogen pipeline networks within chemical parks or refineries
2. Key Technical Components (Based on Public Standards & Industry Practices)
表格
Module    Technical Solution    Reference Standards / Industry Practices
1. Hydrogen Embrittlement-Resistant Pipeline System    - Specialized low-carbon microalloy steel (e.g., modified ASTM A106 Gr.B)
- HEAC™ internal anti-embrittlement coating (Hydrogen Embrittlement Armor Coating): bio-based "brick-and-mortar/molecular lock" structure reduces hydrogen permeation by 99% at 80 MPa, enabling carbon steel to replace stainless steel
- Fully automated welding + 100% non-destructive testing    ASME B31.12 (Hydrogen Piping Code)
ISO 11114-4 (Gas Cylinder Compatibility with Hydrogen)
GB/T 42610-2023 (Chinese Standard for Anti-Hydrogen-Embrittlement Coatings)
Validated in European projects (H21, HyDeploy)
2. Hydrogen-Specific Storage Tanks & Buffer Facilities    - Above-ground or underground spherical/horizontal tanks (design pressure: 1.6–9.8 MPa)
- Materials compliant with EN 10216-2 P355NH or SA-516 Gr.70
- Integrated nitrogen sealing and leak monitoring    CGA G-5 (Hydrogen Storage Guidelines)
GB/T 34542.3-2023 (Chinese Standard for Hydrogen Storage & Transport)
3. Intelligent Control System    - Hydrogen-dedicated SCADA system (IEC 62282 compliant)
- Real-time monitoring of hydrogen concentration, pressure, temperature, and leaks
- Automatic Emergency Shutdown (ESD) with inerting interlock    IEC 61511 (Functional Safety)
NFPA 2 (Hydrogen Technologies Code)
4. U3X Engineering & Construction Capability    - EPC turnkey services: route survey, stress analysis, construction/installation, pressure testing, and commissioning
- Utilizes fully automated welding and digital twin modeling
- Compliant with local pressure piping regulations (e.g., China’s TSG D0001, US 49 CFR)    Referencing Sinopec’s Jiyuan–Luoyang pure hydrogen pipeline and France’s GRHYD hydrogen-blending project
5. U3X Investment & Operation    - Invests in trunkline networks via infrastructure REITs or PPP models
- Provides 20+ years of O&M services (including corrosion monitoring and integrity management)
- Offers open booking of pipeline capacity with fair third-party access    Aligned with the EU’s “European Hydrogen Backbone” initiative
🔹 HEAC™ Technology Highlights:
The world’s only internal coating validated for long-term service life in high-pressure pure hydrogen environments.
Supports in-situ (on-site) coating application, significantly reducing retrofit costs.
Works synergistically with H₂DGR® welding processes to ensure weld zones exhibit no weak points in hydrogen resistance.
3. Differentiated Advantages
End-to-End Integration: Full control over material selection (including HEAC™), intelligent control algorithms, and EPC construction eliminates multi-vendor interface risks.
New Build & Retrofit Compatibility: Supports both 100% pure hydrogen pipelines (design pressure ≤9.8 MPa) and cost-effective upgrades of existing natural gas pipelines for up to 20% H₂ blending—HEAC™ is the key enabler for low-cost retrofits of aging pipelines.
Multi-Layered Safety: A four-tier protection system—“material embrittlement resistance + HEAC™ barrier + online monitoring + automatic shutdown”—meets the highest requirements of ASME B31.12.
Full Asset Lifecycle Management: U3X not only builds but also owns and operates the network long-term, ensuring system reliability and service continuity. The HEAC™ coating has a service life synchronized with the pipeline body, requiring no maintenance for up to 25 years.
4. Typical Application Scenarios
表格
Client Type    Solution Focus
Green Hydrogen Production Hubs (e.g., large-scale wind/solar bases)    High-pressure pure hydrogen trunklines (4–9.8 MPa), using microalloy steel + HEAC™ internal coating to balance safety and economics
City Gas Utilities    Hydrogen blending retrofits downstream of city gate stations, leveraging HEAC™-coated pipelines to avoid costly stainless steel, supporting end-use in CHP or transport
National Energy Conglomerates    Investment in national hydrogen corridor projects (e.g., “West-to-East Hydrogen Delivery”), with U3X providing an integrated “Investment + Construction + Operation” service, featuring HEAC™ anti-embrittlement protection throughout
