ROUND DUCTS

ROUND SPIRAL PIPE

Spiral pipe is fabricated from steel strips helicoidically wound and seamed with a four ply lockseam, which gives the pipe added rigidity. The seam is outside the pipe wall leaving the inside free of obstruction for an optimized air flow.

Spiral pipe is used in a variety of commercial and industrial applications for ventilation and dust or fume collection. They can be made of galvanized steel, satin coat steel, mild steel, or aluminum. They are available in standard lengths of 10 and 5 feet (3050 mm and 1525 mm) or any other length on demand

ROUND LONGITUDINALLY WELDED PIPE
Made from 4 or 5 foot (1220 mm or 1525 mm) metal sheets, these pipes are fully welded lengthwise. They are also available pre-assembled in other lengths and configurations as specified. These pipes are used mainly for industrial applications where thicker walls are needed or where other materials not available in spiral pipe are requested.
