Give and drain off water on skyscraper design supply water exertion, to lay pipeline of tubular product, water gauge produce family set up, establishment and empty of pottype boiler now Transfer condensation water discharge issue discuss together with colleagues. ( 1)supply water tubular product select 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 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。 Pipeline install and in the room, should influence kitchen, bathroom every sanitary equipment use of function tomorrow supply water and prop up there arent tube House supply water prop up and in charge of pipe diameter one ≤ 32mm, de of battle, little plastics feed pipe of pipe diameter is the crooked state, So the house supplies water and is propped up and in charge of being remended and adopted and set up secretly. Supply water to prop up to manage darkly There are thes way had: （ 1)Set up in the brick wall secretly. Wall turn on and in charge of trough in brick when constructing, in charge of trough width tube +20 mm, de of external diameter, degree of depth tube external diameter de, The pipeline is imbedded and managed directly Trough, and with in charge of card fix in trough of inning charge of son. （ 2)Whether pipe diameter supply water and prop up and last de ≤ 20mm,can set up at floor secretly piece make level by layer. Turn on and in charge of trough in floor( ground) the board when constructing, it wides trough have to be de +10 mm deeply 1/2 of the de, Half pipeline imbed and in charge of trough, and with in charge of card fix in trough of inning charge of tube. Aluminium mould pound and in charge of and pay a
