In order to promote the application of chemical building materials and plastic pipe in our country, the national industry departments have issued a number of related industrial policy and promotion file; In order to accelerate the development of chemical building materials and plastic pipe industry development speed, local governments also successively introduced encourages the development of chemical building materials and plastic pipe policy document.

 

At present, the plastic pipe construction in our country brought in order to promote our country's chemical building materials and the application of plastic pipe, national industry departments have issued a number of related industrial policy and promotion files; In order to accelerate the development of chemical building materials and plastic pipe industry development speed, local governments also successively introduced encourages the development of chemical building materials and plastic pipe policy document.

 

At present, the plastic pipe in the field of construction in our country accumulated usage up to nearly 20 million tons. 2008, plastic pipeline engineering construction industry usage reached more than 200, ten thousand tons, including: municipal engineering use about 1.3 million tons, construction of about 700000 tons, the market share of around 45% in 2008.

 

Urban water supply, the application of the plastic pipe, urban water supply plastic pipe mainly PVC -u, PE pipe is given priority to. Main specifications: PVC - U tubes for DN40-710 - mm; PE pipe is DN40-800 mm, maximum to 1600 mm. At present, the cumulative amount of laying: PVC - U tubes reached nearly 90000 km, PE tube reached more than 70000 kilometers, other plastic pipeline almost 20000 kilometers.

 

City gas in plastic pipe: the application of city gas plastic pipe varieties are: high density polyethylene pipe (HDPE), medium density polyethylene (MDPE). Main specifications for 3/4 "- 450 - mm, maximum to 630 mm, at present, MDPE and HDPE pipe in the low pressure gas pipe network in cities the cumulative amount of laying up to 90000 km.

 

Building to cold, hot water, the application of the plastic pipe: building water supply (cold, hot water) plastic pipe varieties are: rigid PVC pipe (PVC -u), chlorinated polyvinyl chloride (PVC) pipe - C (PVC), polyethylene (PE), crosslinked polyethylene pipe (PE - X), polypropylene (PP - R, PP - B) steady-state pipe (pp-r), plastic aluminum, ABS engineering plastic pipes, such as inspecting &controlling plastic pipe. Form for the leading product in the presence of rules copolymerization polypropylene (pp-r), aluminous model multiple tube (PAP) and cross-linked polyethylene pipe (PE - X), etc. Main specifications for DN16-32 mm, use small amounts DN40, (, DN63 automtic. At present, the total project usage reached more than 150 meters (2 million tons).

 

Buildings heating, the application of the plastic pipe, plastic pipe heating varieties are: heat-resistant polyethylene pipe (PE - RT), crosslinking aluminous model multiple tube (XPAP), cross-linked polyethylene pipe (PE - X), polypropylene (PP - R, PP - B), polybutylene (PB) and so on. Main specifications for DN16-32 mm, at present, the plastic pipe in the radiator heating and low temperature hot water floor radiant heating engineering, the cumulative amount of 5 billion meters.

 

Experts according to the construction of housing and urban and rural industry development speed did analysis: in the next few years as the housing and urban and rural construction continued demand for plastic piping, the annual demand is expected to about 3 million tons.
