AMS2244 AEROSPACE MATERIAL SPECIFICATION Tolerances (R) Titanium and Titanium Alloy Tubing
AMS4945 This specification covers a titanium alloy in the form of seamless tubing,the sizes tolerance follow the AMS2244 Tolerances,Titanium and Titanium Alloy Tubing
1.AMS2244 SCOPE: This specification covers established manufacturing tolerances applicable to titanium and titanium alloy tubing.These tolerances apply to all conditions, unless otherwise noted.The term "excl" is used to apply only to the higher figure of the specified range.
1.1 Tubing shall be specified in either inch/pound units or Sl units. When inch/pound units are used, the tolerances shown for SI units are not applicable.When Sl units are used, the tolerances for inch/pound units are not applicable.
2. DIAMETER:
When specified, OD tolerances shall apply to the ID but not to both ID and OD of the same lot of tubing.Mean OD is the average of two measurements taken at right angles to each other. Diameter tolerances include ovality except for tubing having specified wall thickness less than 4% of the specified OD; for tubing with specified wall thickness less than 4% of the specified OD,the ovality tolerance shall be double the diameter tolerance.
2.1 Seamless,Cold Reduced,Annealed or Stress Relieved:
Shall be as shown in Table 1.
