round ducts: spiro pipes
Spiro pipes SPR
SPR spiral pipes made of galvanized sheets are the most popular ducts used in ventilation systems for air flow. Spirally rolled with a sheet metal tape, 137 mm wide, in which the edges of the tape are connected in a tight, crimped lock. Standardly produced in the length of 3 m. No extra charge in the length of 6 m. On special order, it is possible to produce pipes of any length in the range of 0.5 – 6 m. Thanks to maintaining sheet thickness standards, the tubes retain their stiffness without additional reinforcements up to a diameter of 560 mm. From 630 mm in diameter, the manufacturer uses reinforcement in the form of a longitudinal extrusion between the pipe locks.
