Product Description
Product Overview
This 3.16×0.5mm steel Bundy tube manufactured to EN10305-1 DC04 standard features a double-wall construction with copper coating, designed specifically for high-pressure applications including compressor systems and automotive components.
Construction & Manufacturing Process
Double-walled steel tubing is produced from electrolytic copper-coated steel strip wound into a continuous tubular with a double-layered wall. The tube undergoes copper brazing in a specialized furnace using the coated copper as filler metal, creating a seamless, high-strength pressure pipe.
Key Performance Advantages
- Superior pressure resistance and vibration fatigue strength
- Excellent solderability and workability for terminal preparation
- Enhanced bendability and traceability throughout manufacturing
- Ideal for high-vibration applications in refrigeration compressors
