Spiral duct

Formed by connecting a series of spiral or straight pipes and stamping seam welded or hand-made pipe fittings with quick plugs or flanges, the spiral ductwork of MEGAUNITY can meet the requirements of European <DW144> in quality, and the seal capacity can reach the highest of <DW143>, i.e., Class D. The spiral ductwork has been widely used in ships, ocean engineering, public buildings, central ventilation system of houses, industrial ventilation and other fields. And the seal capacity can reach the highest of <DW143>, i.e., Class D.

Product Advantage:

Operating pressure: Withstanding voltage of 3 kPa, and resisting temperature of 120℃;

The largest diameter can be 2,500 mm, and the wall thickness can be 2.5 mm;

The ventilation system composed of spiral duct and fitting can meet the requirements of European <DW144> in quality, and the seal capacity can reach the highest of <DW143>, i.e., Class D.

Imported advanced professional production equipment, spiral duct die making, uniform internal embossing, pipe fitting mould hold-down shaping, standardized and large-scale production, precise size, modern appearance, small wind resistance, and no scratch;

The seam welding process adopted does no harm to the galvanized layer, and the welded joint is neat and aesthetically pleasing with long service life;

Coiled and fixed by F typed silicon seal, it does not slide or fall off during installation, and has good sealing effect and long service life;

Easy to install, and save installation cost;

The insulation system uses the glass silk certified by GL, DNV, ABS and other classification societies as insulating layer, and thus is of light weight, good effect of insulation and long life cycle;

The insulation system has tube plugged both inside and outside, thus having high installation strength.
