Classification And Development Prospect Of Seamless Aluminum Ducts
Aluminum Duct is safe and reliable, hygienic and environmental protection, economical application, thin-walled pipelines and new reliable, simple and convenient method of connecting the development of success, it has more other pipe irreplaceable advantages, the application of the project will be more and more , The use will become increasingly popular, promising.
With the implementation of China's reform and opening up policy, the rapid growth of the national economy, urban housing, public buildings and large-scale construction of tourist facilities, hot water supply and domestic water supply put forward new requirements. In particular, water quality problems, people pay more and more attention, the requirements are also rising. Galvanized aluminum pipe This commonly used pipe because of its easy to corrosive, under the influence of national policies, will gradually withdraw from the stage of history, plastic pipe, composite pipe and copper pipe has become a common pipe system pipe. But in many cases, the aluminum Duct is more advantageous, especially the wall thickness of only 0.6 ~ 1.2mm thin-walled aluminum Ducts in the quality of drinking water systems, hot water systems and safety, health first water supply system, with Safe and reliable, health and environmental protection, economic and other characteristics. Has been domestic and foreign engineering practice proved to be the best performance of the water supply system, the new, energy saving and environment-friendly one of the pipe is also a very competitive water supply pipe, will improve water quality, improve people's living standards play Comparable effect.
