What Is Spiral Pipe?
Spiral Pipe is a spiral steel pipe manufactured by crimping the ends of a strip of steel into a helical shape.
Also called spiral duct, some pipes are made by pressing or deep drawing. The clawed portion is made of overlapping steel strips and has high strength, and the clawed portion runs in a spiral pattern around the circumference of the pipe, increasing the strength of the pipe as a whole.
Spiral Pipe is often used as air conditioning ducts in building construction. The smooth inner surface of the pipe results in very little pressure loss, and installation and pipe connection are easy. Various materials are available, including hot-dip galvanized steel sheet, stainless steel, galvalume steel sheet, and PVC steel sheet.
Uses of Spiral Pipe
Spiral Pipes are used in a wide range of locations as ducts for air conditioning.
1. Factories, Etc.
- Exhaust air of petrochemical plants and pulp manufacturing plants
- Exhaust air of semiconductor manufacturing plants
- Exhaust air from factories in seaside areas
- For exhaust air of factories using chemicals and gases
- Exhaust from animal housing for experiments and clean rooms for experiments
2. Industrial and Public Buildings, Etc.
- Ducts for air conditioning of operating rooms in hospitals
- Flue ducts in factories and stores, heat-retaining piping in plants
- Ducts in office and retail buildings
- Exhaust pipes in tunnels
- Ducts for dust collection in industrial buildings
- Ventilation for sewage and human waste treatment plants
3. Residences, Etc.
- Residential chimneys
- Boilers for water heaters
- Ventilation ducts for kitchen and bathroom toilets in housing complexes, ducts for heating and cooling
Other Information on Spiral Pipe
Features of Spiral Pipe
Spiral Pipe has the following characteristics
1. High Strength
The entire duct is reinforced because it is manufactured with a gauze fold, and it is strong enough to withstand applications such as high-speed ducts, dust collection ducts, and smoke exhaust ducts.
2. Low Friction Loss and Leakage
Spiral Pipe’s high strength results in less deformation during airflow and high roundness. The smooth inner surface of the spiral pipe minimizes air resistance and friction loss. In addition, the spiral spiral ducts have a smaller leakage volume than square ducts, etc., because the spiral ducts are spiral-shaped, which reduces the cost of heat insulation work around the ducts.
3. Easy Installation and Connection
Another major advantage of Spiral Pipe is the ease of installation work, such as connecting Spiral Pipe and suspending it from the ceiling.
Although the degree of resistance varies depending on the material, it is excellent in touch resistance, heat resistance, chemical resistance, and weather resistance. Of course, the price varies depending on the material, so it is necessary to select the material that best suits the application.
