Gelan manufactures and supplies precision-engineered replacement parts for heat exchangers,
fired heaters, furnaces, pressure vessels, and other static equipment used in petrochemical and
heavy-industry plants.
When a single component fails, your entire unit can lose thermal efficiency—or worse, face
unplanned shutdown. We help you extend service life and keep your operation running with:
● Custom fabricated components to match aging equipment
● Compatible OEM-alternative parts without long lead times
● ASME-certified replacement parts for pressure-service reliability
Our engineering team handles reverse engineering, upgrading materials and geometry to improve
performance and reduce future downtime.
Don't replace the whole exchanger when only the bundle is corroded. We provide complete tube bundle replacement services for Shell & Tube Heat Exchangers.
We supply heavy-wall pressure retaining parts for reactors, towers, and vessels.
Precision-drilled components essential for flow distribution and structural integrity.
| Comparison Item | Gelan Solution | Industry Challenge |
|---|---|---|
| Obsolete Equipment | Reverse engineering with on-site 3D scanning and physical measurements to create new CAD models, ensuring full geometric compatibility | Many plants run static equipment 20+ years old; original OEM may be out of business and drawings are often lost |
| Lead Time & Emergency Response | Fast-track fabrication using stocked standard materials and dedicated production lines for rush orders, delivering in weeks | Waiting 6 months for OEM replacement parts is unacceptable during unplanned shutdowns |
| Recurring Corrosion & Failure | Material upgrades to Duplex Stainless Steel, Inconel, or Hastelloy based on failure analysis, extending maintenance cycles | Replacing failed parts with the same material leads to repeated failures and wasted money |
Retubing for Ethylene Crackers, Quench Exchangers, and Polymerization loop reactors.
High-pressure parts for Heat Recovery Steam Generators (HRSG) and boiler economizers.
Corrosion-resistant spares for Ammonia and Urea synthesis loops (High-pressure Strippers & Condensers).
We replicate used parts—even without drawings:
● 3D scanning
● Metallurgy testing
● Creep & fatigue validation
Better performance than the original design.
Every critical component can be produced to:
● ASME U / U2 Stamp
● PED CE
● EAC TR CU
● ISO 9001
100% traceable materials + full QA documentation.
Dedicated fabrication lines for tube bundles, coils, and channel heads
→ Minimize downtime → Recover productivity faster
Get the quality of Tier-1 OEMs without the price premium:
● Drop-in Replacement: Guaranteed to fit existing anchor points and piping.
● CAPEX Efficiency: Save 20-30% compared to buying complete new units from major licensors.
We manufacture parts for heat exchangers, fired heaters, pressure vessels, and static equipment—tube sheets, bundles, coils, channels, shells, and more.
Yes. You can replace just a tube bundle, coil, or channel head instead of a full exchanger—saving cost and shutdown time.
Absolutely. We ensure dimensional accuracy and improved service life—even with older equipment no longer supported by OEMs.
Yes. We recommend Duplex, Titanium, Hastelloy, and Inconel for corrosive and high-temperature media.
Send either:
● Component drawing, OR
● Used part for reverse engineering
Our team responds within 24–48 hours.
Don't let a failing component force a total shutdown. Send
us your drawings or photos of the damaged part.
