Copper Tube

Get ASTM B75 Copper Welded Tubing, Copper Seamless Tubes free sample

One of the specifications considered in the manufacture of Copper Tube is the ASTM B75. Apart from conforming to the chemical parameters, the specified ASTM B75 Copper Welded Tubing also need to conform to the mechanical parameters as well. In terms of the chemistry of these copper tubes, the content of elements copper, arsenic and phosphorous must be met with the chemical requirements specified in the ASTM B75. On the other hand, the Copper ERW Tubes conform to the mechanical property with the requirements such as tensile strength, yield strength, Rockwell hardness, as well as straightening being followed through. Moreover, there are certain tests which not only determine the chemistry and the mechanical properties of the Copper Round Tubing, but these tests are also devised to check if the other requirements such as electrical mass resistivity, grain size and dimensions meet the ASTM B75 specification.


While the specification takes into consideration Copper Seamless Tubes with regards to the construction, these tubes can be formed in various shapes such as round, square and rectangular.  Devised in a manner that could be used to change a high pressure liquid refrigerant into a low pressure spray of refrigerant, a Copper Capillary Tube in simple words is a really thin tube. The aggregate of pressure drop for a capillary tube tends to be dependent on both the tube’s length as well as its inside diameter.
