Application prospect of aluminum-plastic composite pipe

The total amount of hot and cold water pipes in the building should be determined through objective analysis of market demand, so as to balance supply and demand, and avoid excessive and urgent investment in the production of aluminum-plastic composite pipes.

The traditional galvanized steel pipe will be eliminated sooner or later, and the development of the indoor water supply pipe market is a historic opportunity to develop new pipes. But how big is the total consumption of this market, and how much can aluminum-plastic composite pipes account for? It should be actually analyzed and estimated.

One estimation method is to use 2 m of indoor water supply pipes per m of new residential building area. If China’s new residential buildings in 2000 were 300 million m2 (according to the construction statistics of the Ministry of Construction, China completed 345.27 million m2 of urban newly-built houses in 1996, of which residential housing was 300 million m2). 215.8 million m). The total demand for indoor water pipes is 600 million m. Assuming that 30% use various new plastic indoor water supply pipes, 180 million m is required. If aluminum-plastic composite pipes can account for 30% to 50% of them, the market for aluminum-plastic composite pipes in 2000 is about 60 million m to 90 million m. Compared with the European experience of using plastic water supply pipes for a long time, the actual performance of 65 million m of aluminum-plastic composite pipes in 1997, if the consumption of aluminum-plastic composite pipes in China reaches or exceeds 60 million m in 2000, it will be a very gratifying progress. . However, compared with the production capacity of aluminum-plastic composite pipes that has been invested in China, the difference between market demand and production capacity is nearly three times.
