On the other 11 Яе0.021.070 TU-86 the surface of the strips should be without bundles, rolled out of the cracks and bubbles, rolling and captured shells - Udalov. Allowed some risks, scratches, fingerprints from the rolls, nakoly - punctures, if the control sweep defects they cannot make the sizes of strips for the limit deviation on thickness. |
