    Lengthwise, tubes are manufactured in specified length from 3.5 m to 7.8 m with allowance +15 mm, without cutting and putting off burrs. Rounding radius is not more than 2s (two wall thickness of the tube). The curvature of the tube does not exceed 2 mm on 1 m of length of the tube. During tube manufacturing inside bead should not be more than 0.6 of the thickness of the tube wall.
