1. Dimensional accuracy

The permissible deviation from the outer diameter of the weld treatment includes the elliptical circle a in categories I and II.

I.Deviation of the inner and outer diameter of class mm

Outer route	Intake air diversion
<>	±0.10
≥25-38.1	±0.15
>38.1-50	±0.20
≥50-63.5	0.25
>63.5-76	±0.30
≥76-102	±0.40

Deviation of the outer diameter of class II mm

Outer route	Intake air diversion
≤10	±0.15
>10-32	±0.20
>32-50	±0.30
>50	±0.8%

The allowed deviation from the welded tube wall thickness (excluding welding) is 10% of the wall thickness, but the minimum allowable deviation is 0.02 MMS.

The length of the weld scale is 3 ms to 9 ms, and the overall length of the scale is 6 Ms.

The seam length is fixed to the normal length and the allowed deviation is ± 5 mm.

Welded pipe that maintains the measurement of China's leg by partial retraction must not be less than 2.0 mm.
