1, product standardization.
Spiral duct fittings (ie, fittings and joints) have been highly automated, systematically designed and produced, and have an industrial quality control system.
2. Low installation cost.
的时间。 The installation time of a circular ventilation duct system is only 1/3 of that of a similar rectangular duct.
3, usually only a small installation space can save space.
的圆形管道可取代250 × 150mm的矩形管道。 Without increasing any pressure drop, a round pipe with a diameter of 200mm in the same installation space can replace a 250 x 150mm rectangular pipe. Without adding additional installation space, several parallel circular pipes can replace flat rectangular pipes. Taking all factors into account, in most cases, circular ventilation ducts take up less space than rectangular ducts. For the same pressure characteristics, the installation space of several round pipes is often the same or less than that of a rectangular pipe.
4, the pressure drop of the duct: As we all know, the wind resistance of the circular duct is much smaller than that of the rectangular duct.
5. Precision bite molding process: The molds used in the imported equipment are all special steel structures. Even after three or five years of use, the surface of the pressing mold remains unchanged, so that the surface of the galvanized steel sheet is not damaged. Extend the service life of the air duct, meanwhile, the joints are even and flat, the mouth is tight, the connection is strong, and the seal is good.
6. The safety seal has a leak-proof system.
，降低成本。 7. The exquisite spiral pressing corrugated rib process makes the spiral duct have the best strength to withstand the pressure. After increasing the spiral corrugated rib, the thickness of the undercut at the mouth is four times that of the pipe body, thereby increasing the rigidity of the pipeline and showing It has the advantages of sturdiness, and can bear the largest pressure load so that it is not easy to deform. It can reduce 15% on the pipe and reduce the cost.
9, the pipeline layout is beautiful, strong three-dimensional: when the pipeline as a building feature must be exposed, the beautiful code of the molding flange to connect the duct with the duct.
