3. Emerging Technologies
- Enhanced inner tube surface corrugation for improved turbulence at low Reynolds number flow is advancing double pipe heat transfer coefficient for viscous fluid heating. Growing corrugated tube adoption is improving double pipe thermal efficiency at the low flow velocities typical of viscous pharmaceutical and polymer service.
- Modular hairpin double pipe unit design enabling field capacity extension by adding hairpin modules is advancing for pilot and scale-up plant flexibility. Increasing modular double pipe design is improving plant operator ability to scale heat exchange capacity without replacing existing units during production increases.
- Non-destructive testing of double pipe inner tube wall thickness using phased array ultrasound is advancing for predictive corrosion maintenance. Continued UT inspection capability is improving double pipe exchanger life management at pharmaceutical and chemical facilities requiring documented tube integrity.
- PTFE and fluoropolymer-lined double pipe exchangers for aggressive chemical service are advancing in manufacturing quality for pharmaceutical and semiconductor applications. Expanding lined double pipe availability is improving heat exchange options for highly corrosive process streams incompatible with stainless steel.
