TECALEMIT FLEXIBLES® multitubes are comprised of MANURIL® tubes as defined in paragraph 3-1 which are then spiralled together, in some cases covered with a polyethylene film, and sheathed with a 1.5mm to 2mm thick polyvinyl chloride coating. TECALEMIT FLEXIBLES® multitubes : - reduce size of bundles comprised of individual tubes. - increase productivity in installation. - protect tubes from impacts and weather. - have low bend radius. The technique of spiralling gives remarkable flexibility and bend radius to the finished product and maintains tubes at the same length in bends. The thick PVC coating keeps a round shape and ensures excellent protection, not only mechanical but also against many acids, bases, alcohols and oils. The seven MANURIL® colours are used for easy identification of tubes. Specific productions are regularly carried out, for example incorporating tubes of different diameters, electric or communication cables, pulling cables, a circular reinforcing steel braid placed before the pvc coating, MANUlan® polyurethane tubes.
Marking of TECALEMIT FLEXIBLES® multitubes is as follows : “tecalemit flexibles - part N° - multitube n tubes IDxOD - batch N°“(for multitubes of n tubes). TECALEMIT FLEXIBLES® multitubes are regularly produced in lengths up to 1000 metres on reels. They are then repacked in multiple lengths of 25 metres.
