Financial information

Economic Context & Market Potential (Polish Market Exclusive)

- Polish oil & gas pipeline market: ~€2-3 billion annually (PGNiG, Orlen, PERN investments in Baltic Pipe, shale gas, and high-pressure infrastructure upgrades). Growing demand for durable pipes in deep drilling and corrosive environments (offshore Baltic Sea, Carpathian basins).

- Target applications: High-pressure pipelines for natural gas extraction, petrochemical refining, geothermal energy, and industrial construction. Current pipes fail 2-3x faster in harsh conditions, causing €10-50 million losses per incident (downtime, leaks, repairs).

- Benefits for buyer/licensee:
- 200-300% increased flow rates with larger diameters (up to 500mm+ in hard materials like titanium/steel alloys).
- 50-70% reduced maintenance costs over 10-15 years (no cracks from bending deformations).
- Quick ROI: Single mid-sized project (e.g., 10km pipeline for PGNiG) saves €5-15 million in replacement costs.
- Production scalability: Low-cost robotic manufacturing – payback in 12-24 months for licensed producer.

- Total addressable market in Poland: €500 million+ for premium high-pressure pipes (2025-2030, driven by EU Green Deal and energy security investments).
- Global licensing potential: Despite Polish-only protection, technology freely usable abroad – buyer can file new patents internationally for worldwide exclusivity.

Fixed price: 700,000 EUR – exceptional value for exclusive Polish rights in a niche high-margin sector. Full financial model and references available upon NDA.

POLISH-ONLY PATENT BUT TECHNOLOGY FREE WORLDWIDE! Ideal for global manufacturing – buyer gets exclusivity in Poland + full know-how for production anywhere else. No restrictions outside PL. Perfect for oil/gas pipelines in harsh environments.
