连接方便简单; (1) Easy and simple connection ;
The installation of the spiral air pipe can reduce the connection points between the air pipe and the air pipe, so that the leakage of the joint of the pipe can be minimized. Moreover, only one joint is needed to connect two spiral ducts, and the connection of traditional rectangular ducts requires a completely independent double flange system.
standardized products ;
Spiral duct fittings
, including pipe fittings and joints, have been automated, systematic and produced with industrial quality control.
Low installation cost
The installation time of the spiral duct is only one third of that of the rectangular duct.
Usually requires less installation space
Under the premise of no additional installation space, several parallel spiral ducts can replace rectangular ducts, and they occupy less space than rectangular ducts.
The wind resistance of spiral duct is much smaller than that of rectangular duct.
Precision bite forming process
The molds used are all special steel structures. Even after several years of use, the surface of the pressing mold can remain unchanged, and the surface of the galvanized steel sheet will not be damaged. Good sealing.
Leak-proof system of safety sealing ring, using spiral pressing rib technology
The process can make the spiral air duct have a good pressure resistance, the thickness of the bite slot is four times that of the pipe body, which increases the rigidity and superiority of the pipe, and can withstand large pressure loads without damage and deformation. ，降低了成本。 In addition, the material thickness can be reduced by 15%
, which reduces costs.
