Abstract

Process of maturation of tubes manufactured on mandrels and that keep after the boring some plasticity that only disappears after more or less prolonged drying, particularly cement-asbestos tubes, characterized by the fact that after boring, each tube is still soft in a rigid hollow mast, longer than the aforementioned pipe and therefore supporting the latter over its entire length, and this rotation is printed on this shaft, so that, throughout the hardening period, the tube rolls through the inner wall of the mast and due to this fact remains straight, while its normally lightly ovalized section, at the time of the derailment, remains perfectly circular.
