Copper Capillary Tube
Copper Capillary Tube Application:
Usually,Copper Capillary Tube is the name given to all tubes whose outside diameter is less than 4 mm. Wall thickness is usually less than 1 mm and, in some special cases, it may be extremely thin, although never less than 0.25 mm. Capillary tubing is usually supplied in coils and, apart from exceptions, it comes in annealed form.
Copper capillary tubing is used throughout the refrigeration and air conditioning industry for restriction applications. This tubing is produced in C12200 copper to the hard drawn temper. It is plug-drawn to close tolerances and processed to meet specification ASTM B360, with clarification in regard to end finish and flow testing. Color coding of tube is also available.
Special emphasis has been attached to the production of capillary tube with ends that are free of burrs and chips. This is achieved by brush deburring with rotating wire brushes. After the ends are finished, they are examined under an illuminated 3X power magnifier to assure burrs and chips have been removed.
