Quick Details
Specifications
1. PRODUCT DETAIL:
copper coated tube(Bundy pipe) is type of double-wall or single-wall low carbon steel tube manufactured by rolling a copper-coated steel strip through 720 or 360 degree and resistance brazing the overlapped seams in a process called bundywelding. Ii may be zinc-coated and PVF-coated for corrosion protection. It's used in automotive hydraulic brake line in car manufactured in the USA.
