The spiral wind pipe joint is circumferential seams, the strength is much higher than that of straight radial intensity, so can ensure that the joints at 1.5 times the working pressure without cracking, because the raw materials and the whole piece of galvanized steel galvanized steel sheet, a lower price, plus its factory production standard and standardization the cost is lower than the pipe, rectangular wind.
In addition, because of its small amount of support and hanger, less installation work, so the total cost is low. Because the four corners of the rectangular duct are prone to turbulence, the effective flow area is reduced, the air flow is good, and the effective flow area is large, so the noise of the commodity is small, because the intensity is large.
Spiral duct of the whole industry to develop, he is not relying on his price, should be the overall quality of the industry.
To the goal of energy saving, energy saving and environmental protection enterprises all around the theme of the activities, to increase investment in new product development, product design, manufacturing technology, production line technological transformation, promote the upgrading of equipment.
