Product Description
3.16×0.5mm Double Wall Brazing Steel Tubing
SPCC thin wall galvanized tubing engineered specifically for compressor applications requiring exceptional vibration resistance and durability.
Product Overview
Double-wall brazed steel tubing is manufactured by roll forming copper-coated carbon steel strips into a double-wrapped tubular configuration, then fused together in a controlled atmosphere brazing furnace to create a completely sealed tube structure.
This construction method makes double-wall tubing ideal for applications subject to high levels of vibration and fatigue, particularly in household and commercial refrigeration compressors where reliability is critical.
Available Coating Options
Both single and double wall Bundy tubes can be enhanced with various corrosion- and abrasion-prevention coatings:
- NyAl (aluminum and polyamide coating)
- NyZinc (zinc and polyamide coating)
- NyGal (Galfan and polyamide coating)
- PVF coatings
- Polypropylene jackets for outstanding abrasion resistance
