Demension Tolerance

The specified outside diameter is 48.3 mm and the specified wall thickness is 3.2 mm for type 3 and 4.0 mm for type 4
Tolerances on dimensions
The tolerance on specified outside diameter is +/-0.5 mm.
The tolerance on out of roundness is included in the diameter tolerance.
The tueraire o yal tiuckires -10% However, for seamless tubes,a deviation from specified wall thickness of more than 10% bur no more than 15% of the specified thickness may occur in smooth transition areas over no more than 25% of circumference.
The inside diameter of tubes shall allow insertion of a gauge of diameter 37.7 mm for a minimum length of 200 mm
