Brazed Double Wall copper-coated Bundy tube used for Compressor


Copper brazed double-wall steel tube is made of steel strip which is copper plated on both sides. It has widely applied for automobiles, refrigerators and other hydraulic system industries.


Brazed Double Wall Tubing

Double-wall tubing is produced by roll forming copper-coated carbon steel strip into a double wrapped tubular shape as shown in the cross-sectional diagram. The formed tube is passed through a controlled atmosphere brazing furnace where it is fused together to produce a sealed tube. Double-wall tubing is ideally suited for use in applications that are subject to high levels of vibration and fatigue, such as household and commercial refrigeration compressors.


Single-Wall Steel Tubing with the same coating range as double-wall tubing but with the addition of a nickel-coated internal diameter to withstand the corrosive environment created by modern-day fuels.

Single & Double Wall Steel Tubing Bundy tubes that can be combined with an extensive range of corrosion- and abrasion-prevention coatings such as NyAl (aluminum and polyamide coating), NyZinc (zinc and polyamide coating), NyGal (Galfan and polyamide coating), PVF and many others. These tubes can also be provided with a polypropylene jacket to provide outstanding abrasion resistance.
