Detailed Product Description

1.Introduction:

Double wall copper-brazed steel tubing(also known as the Bundy, double-wall pipe) is made of high-quality cold-rolled strip by the double-sided copper, rolled winding two laps (720 °) and brazing in the reduction  atmosphere. it has a high burst strength and good inner surface cleanliness, a good anti-vibration and fatigue-resistant properties. It is the best alternative to brass for its reliable performance. Comparing with brass, it has lighter weight, better performance, and lower price.

2.Usage:

Automotive and refrigeration industry used as pressure tube ,such as oil tubing, trachea, brake pipe, condensers, evaporators.

3.Standard:ASTM A254 ,SAE J527, GB11258-1998( YB-T4164-2007)

4.Size:

5.Main Characteristics:

Fine inside cleanness, high strength, nice elongation, good foundation for late processing, anti leakage, anti high pressure explosion, excellent anti corrosion power after surface treatment. It is an ideal material for tubes of condensation, evaporation and autos. The tube can be provided in coils or cut to length.
