The elucidation of the residential water supply has always been important to the adoption of steel, iron, galvanized pipe, because the
inner wall is easy to rust, scaling, the growth of bacteria and microorganisms harmless impurities, so that the water caused by "secondary
pollution" in the pipeline transporting. Daily subsistence, the quality of drinking water and water mains peace is a core of people save
families. The metal tube has four major life for life shortcomings: rust, easy to corrupt, leaky, easy to scale. Galvanized steel is corrupt
after breeding all kinds of microorganisms, to purify the water in the pipe. Clean tap water to take care of bacteria like tangible killer,
always intimidate people healthy.
The past 10 years, some get rich country has been around the legislative or create industry regulations to stop the use of galvanized steel
pipe as the water conveyance pipe, and the comprehensive use of the green pipe does not rust, no corruption, no leakage, no scaling good
pipe.
Recently, the "12th five times the two sessions, the world people s deputies also proposed on the initiation of comprehensive implementation
of new energy saving green pipe, to promote energy saving and the cycle of economic growth". Suppression of cold-galvanized steel and
various types of composite cast iron water pipe to limit the use of hot dip galvanized pipe, promoting the use of new types of plastic pipe
and plastic pipe and other green pipe is imperative. "
It is reported that staff initiated the relevant part of the State to introduce a series of policies and the pace of financial subsidies,
and the comprehensive implementation of the same green pipe of HDPE these new energy saving and environmental protection.
According to the first volume of building materials experts, China produced important green pipe polyethylene pipe (PE), polypropylene tube
(PP), polybutylene pipe (PB) plastic composite pipe (PAP), more than 80% of these pipes with in the construction of water supply and
radiation heating. Relative the rest of plastic pipe, more properly used for indoor small-bore water pipes, radiation mining gentle floor
heating, indoor low-pressure gas pipe. 1997 aluminum tube using a narrow range, yield less, the market rarely trafficking. However, since
1997, because the Ministry of Construction in the new room, limited use galvanized pipe, recommend use of polyethylene pipes, polypropylene
pipes, new green pipe, polybutylene pipe and plastic composite pipe is, the green pipe market sales potential, sales booming, some types of
demand exceeding supply, the people a new economic increase point and become a popular investment. According to market inquiries visit the
performance of these green pipes for two consecutive years from 2002 to 2003 recovery in production has reached more than 3 million tons, it
is estimated that 2012 will span more than 3.5 million tons.
Market inquiries, visit the performance of 1997 In the future, because the green pipe market is heating up around the herd, has resulted in
the market is very chaotic, quality, yield and cost of ups and downs of market co-operation is very severe. In this regard, the Secretary-
General of the Association of suppliers of domestic molds and metal plastic property Luo Baihui the first volume, at the present plastic
pipe in China market economy is more severe, a wide range of plastic pipe production enterprises over 3000 years producing ability of over
15 million tons with an annual capacity enterprises amounted to more than 10,000 tons of 300, 20 more than an annual capacity of over 10
million tons.
Britain at the end several years of sharp market cooperation and consolidation in the industry, some of the equipment, the degree of
difference, a small production line, production of small, low quality, small factories around to enter the market and new collaborators rare
opportunity to enter. Estimated polyethylene pipe in the next several years, polypropylene pipes, polybutylene pipe and aluminum-plastic
composite pipe and green plastic pipe market will link to a stable growth trend.
Followed by the growth of science and technology, the quality of people s subsistence inexhaustible progress, self-care sense of
inexhaustible strengthen the "Healthy" and "peace" as the two main themes that contemporary people save most families. Analogy,
environmentally friendly plastic pipe water supply pipe with galvanized steel due to have the strengths of harmful corrosion resistance,
thermal conductivity is small, while more was the favorite of the contemporary city people seeking a healthy and stylish subsistence. Green
plastic pipe market in the future will inherit a stable increase in growth.
