Product Description
DELLOK YONGHUI Dual-Enhanced Finned Tubes
DIESTA represents innovative finned tube technology specifically engineered for air cooled heat exchangers. This advanced solution utilizes enhanced surfaces to improve plant efficiency and reduce construction costs while maintaining compliance with robust oil & gas industry standards including API 661.
Key Applications
- LNG air-cooler systems including MR compressor intercoolers and aftercoolers
- Refrigerant coolers (desuperheater, condenser and subcooler)
- Ethylene quench-water air coolers for naphtha-based crackers
- Gas processing plants and compression stations
- Refinery operations
- Available for both greenfield projects and revamp debottlenecking applications
Performance Benefits
Cost Savings
Achieve up to 20% reduction in air-cooler field length, resulting in significant savings on structures, piping, wiring, and foundation costs.
Revenue Enhancement
Substantial operational benefits depending on process conditions, with LNG air-cooler optimization delivering up to 3% capacity increase.
Environmental Impact
Improved system efficiency reduces compression work, contributing to a lower CO₂ footprint.
Technical Design
The DIESTA tube features a bimetallic construction with an aluminum sleeve fully covering the base carbon steel tube. External aluminum fins are embedded into the sleeve grooves, while enhancement structures optimize both airside and tubeside heat transfer performance.
Airside Features
Combined groove and dimple structures on aluminum fins provide enhanced heat transfer while maintaining mechanical strength, fouling resistance, and cleanability equivalent to standard extruded finned tubes.
Tubeside Features
Internal helical fin structure increases tube side heat transfer coefficient while effectively managing pressure drop.
Frequently Asked Questions
What are the primary benefits of DIESTA finned tubes?
Benefits include up to 20% CAPEX savings through reduced air-cooler field length, increased revenue potential with up to 3% capacity improvement in LNG applications, and enhanced environmental performance through reduced compression work.
How is the DIESTA tube constructed?
The tube features a bimetallic design with an aluminum sleeve covering the carbon steel base tube. Aluminum fins are embedded into sleeve grooves, with enhancement structures on both airside and tubeside for optimal heat transfer.
What makes the airside fins unique?
The airside fins incorporate both groove and dimple structures that have been mechanically qualified for fouling resistance, cleanability, and strength matching standard extruded finned tubes.
