【正文】 lect problem for use Traditional watersupply tubular product adopt zincplated steel tube generally, because zincplated steel tube exchange the corrosion, Use shortlived , use for and send domestic water can satisfied with water quality sanitary standard shorting, Ministry of Construction is popularizing the application of the feed pipe of plastics energetically . A lot of districts and cities have already expressed regulations: Forbid designing and using the zincplated steel tube , use widely the feed pipe of plastics. The plastics supply water In charge of pared with metal pipeline, light, it is fine to able to bear the intensity of keeping, Send obstruction little liquid , able to bear chemistry better to corrode performance, it is convenient to install, The steel energyconservation of the province, merit of having long performance life etc.. Supply water and use plastics pipeline: Hard polyvinyl chloride( PVCU), high density polyethylene( HDPE), pay and unite polyethylene( PEX) , modify the polypropylene( PPR, PPC), gather butene( PB), aluminium mould and pound and in charge of and the steel is moulded and pound and is managed etc.. Choice of tubular product economic parative 1 course of technology, technology should from pressure, temperature, environment for use, install method,etc. go on and consider, Combine owners at the same time request and the house of grade,carry on and fix after being consider synthetically technology not economic. The above plastics supply water tubular product can supply water tubular product as house life. The economic and functional house conciliating Strand room in the face of the masses of with low and mediumlevel ines resident, can select for use hygiene grades of hard polyvinyl chloride in charge of as feed pipe mainly, In order to reduce the fabrication cost。 Mediumtohigh grade modity apartment available aluminium Mould and pound and in charge of or other plastics supply water the tubular product as the feed pipe. House mix hot water temperature that water order exceed 600 C, so abovementioned tubular product in charge of except hard polyvinyl chloride and aluminium plastics pound and in charge of( PEALPE), Mostly the tubular product can be regarded as the hot water pipeline of the house. ( 2) pipeline lay problem 1. give and drain off water it set up there arent one that in charge of 1)Will install it in the corner place of the kitchen, bathroom tomorrow. Adopting this kind of way of laying more in the design of house in the past, it is convenient for it to construct, But will reveal the pipeline and hinder the room beautifully tomorrow Watch, the households will mostly be hidden with the light quality material in the equipment two times. 2)Will install it in the overcast angle place of the outer wall of the building tomorrow. Way this suitable for southern weather warm district only, the minimum temperature in winter cant be lower than zero degrees Centigrade, In case water pipe waterlogging freeze ice is bloated to split pipeline, influence household use. Pipeline lay in outer wall, influence building to be beautiful, too inconvenient on manage and maintain in the future. 3)Lay it in the pipeline well. This way makes the room clean and beautiful , but the pipeline well has taken up the area of the bathroom, And pipeline construct, maintain relatively more difficult. Bathroom set up concentrate pipeline well, concentrate pipeline on assign in the well feed pipe, drain pipe, This is that the civilized importance lives in the kitchen of fortable house, bathroom Embodiment. I think : Should consider the establishment of the pipeline well of the bathroom in the mediumtohigh grade building conceptual design of modity apartment, Improve quality of using of bathroom promptly so , can solve hard polyvinyl chloride drain pipe rivers noise heavy problem, Improve the environmental quality level of the room。 Pipeline install and in the room, should influence kitchen, bathroom every sanitary equipment use of function tomorrow 2. supply water and prop up there arent tube House supply water prop up and in c
