Copper tubes widely used in air conditioning, refrigeration,
construction, decoration, hardware tools manufacturing, auto
fittings, heating elements, ship building etc.
We offer copper pipes as clients requirements, manufacturing
according to main countries standards, such as ASTM B280, ASTM B88,
ASTM B111, AS1432, GBT 5231-2001, EN12449:1999, EN3600:2002
etc.
The tubes should be produced from the following coppers, and
the manufacturer has the option to supply anyone of them, unless
otherwise specified:
