Product Introduction
Aluminum Microchannel Tube 1-220 mm Wall
Aluminum microchannel tube (industry aliases: multi-hole extruded tube, flat multi-port tube, MPE tube) pushes wall bandwidth to an industry-leading 1 mm–220 mm, giving design engineers freedom to optimize surface-to-volume ratios from 50 m²/m³ up to 1 200 m²/m³.
The enlarged internal fin-to-channel interface lifts overall heat-transfer coefficient (HTC) by ≥30 % versus conventional round pipe, translating into 15 % lower kWh consumption for residential and commercial HVAC units .
Product Features
Aluminum Microchannel Tube 1-220 mm Wall
We continuous-seam-weld 3003-modified or 6063-T5 billet through a 12 000-ton porthole press, maintaining ≤±0.02 mm wall tolerance and ≥6 MPa burst pressure even at the 220 mm ultra-thick corner.
Every coil passes 2.5 MPa helium leak test (<1×10⁻⁹ Pa·m³/s) and 1 000 h neutral salt-spray to ASTM B117, ensuring 15-year field life in coastal or polluted environments .
Typical outer dimensions span 10 mm–220 mm width × 1.2 mm–30 mm height; channel count 3–90, hydraulic diameter 0.4 mm–8 mm.
Options include zinc-spray 5–25 g/m², chromate-free flux coating, or internal rifling for super-critical CO₂ heat-pump systems.
Supplied straight (3/6 m), LWC (≤300 kg), or CNC bended to ≤0.5×tube height radius without crack
