Toyo Alchitite Industry Air Conditioning Spiral Duct
The inner surface of the cylinder is smooth, resulting in very little pressure loss, and the installation and continuation of the pipe are also easy.
Spiral ducts are spiral steel pipes made by winding strip steel with a width of 100mm to 150mm and a thickness of 0.5mm to 1.0mm, while crimping both ends of the strip steel. The overlapping sections consist of four layers of strip steel that spiral around the outer circumference of the pipe, enhancing the pipe's strength.
