Abstract
Rigid helically sewn tube with reinforcement ribs and splicing thread of the type formed from sheet metal bands or strips wound helically and crimped in this same direction, characterized in that each band in the adjacent margins has a seaming line and the rest in number and proportion to the width of a series of internal grooves that generate external nerves in the same helical arrangement, considerably reinforcing the body and allowing, in the association of complementary diameters, the joining of modules by threading.
