American Standard ASTM A179, seamless cold drawn low carbon steel heat exchanger and condenser tube.
 
This pipe materials and Chinese GB 10 # somewhat similar. But you should note that not correspond to over steel can be used to do this a number of steel. You should pay attention to the detailed requirements of the original standard, pipe inspection and testing what should be done, do not use just any garbage 10 # steel instead oh.
 
Another A179 standard surface finish of the steel pipe is also a requirement, A179 steel hardness of the finished product is also a requirement, general domestic small pipe factory, arrange improper heat treatment process, often resulting in inferior quality steel.
Must pay attention to, oh, not corresponds to a steel can, moreover, not all of the 10 # steel A179 can be used to make steel pipe. Standard chemical element composition which has made ​​its requirements, some steel mills  GB is 10 # steel, but Ann A179 is unqualified. Be sure to pay attention to Oh.
