Sequent to cold working, the tubing shall be normailzed via an atmospherically controlled method to produce a finished product that will meet all requirement of SAJ525
Dimensions and Tolerances:
The tolerances applicable to the tubing outside diameter and inside diameter are shown in Table 1.
The tolerances applicable to the tubing wall thickness are shown in Table 2
