Brief Introduction
galvanized steel spiral duct fittings
PRODCUT DETAILS
TheGalvanized Steel Pipe Fittings and Nipples
TheGalvanized Steel Pipe Fittings and Nipples installation of spiral duct significantly reduces the connection point between pipes, so that the leakage of pipe fitting joint is reduced to a minimum. The typical length of spiral duct is 3~6m, while that of the typical rectangular duct is only 1~1.5m.The connection of two spiral air ducts only requires one pipe joint,
while the connection ofGalvanized Steel Pipe Fittings and Nipples traditional rectangular air ducts usually requires a completely independent double-flange system.
1.Standardized products
TheGalvanized Steel Pipe Fittings and Nipples production of spiral pipe fittings (pipe fittings and joints) has been highly automated and systematized with industrialized quality control.
2. LowGalvanized Steel Pipe Fittings and Nipples installation costA circular duct system takes about a third as long to install as a similar rectangular duct.
3, usuallyGalvanized Steel Pipe Fittings and Nipples only a small installation spaceA 200mm diameter circular pipe in the same mounting space can replace a 250 150mm rectangular pipe without increasing any pressure drop.ParallelGalvanized Steel Pipe Fittings and Nipples circular pipes can replace flat rectangular pipes without adding extra installation space.
All things considered, for the mostGalvanized Steel Pipe Fittings and Nipples part, circular pipes take up less space than rectangular ones.For the same pressure characteristics, theGalvanized Steel Pipe Fittings and Nipples installation space of several circular pipes is often the same or less than that of a rectangular pipe.Many rectangularGalvanized Steel Pipe Fittings and Nipples piping systems require a 4-bolt system to be installed, thus adding 40 to 80mm in all directions of the piping.
4.Galvanized Steel Pipe Fittings and Nipples Pressure reduction: the wind resistance of the circular duct is much smaller than that of the rectangular duct.
5, the precision of Galvanized Steel Pipe Fittings and Nipples process: imported equipment mould are adopted by the special steel structure, even using the three to five years, its Galvanized Steel Pipe Fittings and Nipples suppression of Galvanized Steel Pipe Fittings and Nipples mould surface remain unchanged, making the Galvanized Steel Pipe Fittings and Nipples surface of galvanized steel plate is not damaged, greatly extend the service life of the duct, uniform flat seam at the same time, bite tight, even the Galvanized Steel Pipe Fittings and Nipples relay is strong and good sealing.
6. Safety Galvanized Steel Pipe Fittings and Nipples sealing ring anti-leakage system
7, delicate Galvanized Steel Pipe Fittings and Nipples spiral suppress stare blankly Galvanized Steel Pipe Fittings and Nipples technology make spiral duct has the best strength under pressure, increase the spiral stare Galvanized Steel Pipe Fittings and Nipples blankly after reinforcement, bite hidden seam thickness is four times the size of the pipe body, Galvanized Steel Pipe Fittings and Nipples pipeline of Galvanized Steel Pipe Fittings and Nipples very large rigidity, shows the advantages of strong, can Galvanized Steel Pipe Fittings and Nipples withstand the maximum pressure load and nondestructive deformation, Galvanized Steel Pipe Fittings and Nipples material thickness can be reduced by 15%, reduce the cost.
8. For the Galvanized Steel Pipe Fittings and Nipples same cross-sectional area, the circumference of the rectangular duct with a aspect ratio of 1:3 is 40% longer than the circumference of the spiral duct, saving material; Similarly, due to the length of spiral duct, Galvanized Steel Pipe Fittings and Nipples insulation materials can be reduced accordingly.
9, the Galvanized Steel Pipe Fittings and Nipples pipeline layout is beautiful, three-dimensional strong: when the pipeline as an architectural characteristics and must be Galvanized Steel Pipe Fittings and Nipples exposed, beautiful and elegant shape flange duct will be the best choice.10,Galvanized Steel Pipe Fittings and Nipples socket type spiral round wind pipe installation.
