Quick Details
Specifications
1. PRODUCT DETAIL:
Bundy 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.
1 ) Advantage of yellow zinc coated Tube:
a. Good corrosion resistance;
b. Excellent mechanical properties;
c. Low-pressure loss;
d. Comparatively light in weight
e. Sturdy shape, pleasant to the eye when exposed;
f. Impervious to harmful chemical;
g. Cost effective;
h. Recyclable & have resale value.
2 ) Plating: Cooper coated
3 ) Certifiction: ISO9001
4 ) Package: cut-to-length /in coils, as your requirement.
5 ) Standard: Country YB/T4164--2007
6 ) Shape: Round
7 ) Raw materials: low carbon steel tube/ BHG2
8 ) Surface treatment: white /dark green/ orange red/ olive green/ color zinc
