PPR pipe main stream

Domestic: PPR pipe main stream "as the hydropower project of the pipe, in just two or three years has been upgrading several times." Woodpecker decoration, according to the Commissioner of the registered inspector Zhaotai Yu introduced the first stainless steel tube, galvanized steel, and aluminum plastic pipe, and then include the PPR plastic pipes, etc., and, finally, the international standards of current and thin-walled copper tube. Which galvanized pipe, PVC pipe has been almost eliminated; plastic composite pipe, brass and stainless steel tube defects or because of their high cost and other reasons, the actual amount of decoration in the present is not, the most commonly used is the PPR pipes. However, "These pipes have not been the test of time, some construction in recent years the overall pipeline system problems occur, many of the hidden dangers left behind a few years ago." Such as galvanized pipe out of the muddy yellow water; aluminum tube compression easily when burst. Even the main stream of PPR pipe, there are some problems: In the long-term use in the precipitates will be generated on the human body has not yet been determined. Overseas: what the most widely used copper pipe quality is the best? It is understood that the current international use than brass. Brass both high and low temperature resistance, strength, environmental protection and sanitation has a distinct advantage. Copper in the developed countries or regions in both water supply and drainage system monopoly. Such as Hong Kong, copper accounted for 70% of the market, residential construction in the domestic water system is required by law to use brass. Britain and other developed countries established a higher prevalence of brass. But in China, the utilization rate has been low brass. Wuhan Golden Harvest Group Open Houses and technology lecturer Wu Jixiang told reporters, "In addition to the high cost of factors, but also, and we use the concept of a great relationship." Cities in the domestic market, according to optimistic estimates, about nearly 10% usage. Currently concentrated in high-end users brass, such as five-star hotel and senior housing communities. "By contrast, the phenomenon of burst water pipes in these areas will be significantly less than normal."
