1. Thickness variation can’t lead the wall out the limit deviations concerning wall thickness.
2. In pipe cross-section the deviation from right angle can’t be more than ±1.5°.
3. Pipe curvature can’t be more than 2 mm for 1m of length.
Pipes are produced without adjustment, in this case curvature is not regulated.
