Er það mælt með að nota kopar pípur fyrir bygging vatn vatnsveitu rör?

Innri veggur af kopar rör er þunnur og sléttur, gerir ekki form mælikvarði, og hefur mjög lítið vatn viðnám, sem dregur úr þrýsting tap og flutningur kostnaður. Vegna þess að kopar pípa hefur a lágt varma stækkun stuðull (1/10 það af plast rör) og a stór varma leiðni (4 sinnum það af ryðfríu stáli rörum), það á áhrifaríkan hátt dregur úr hita tap í heitu vatni pípum. Endurvinnsla hlutfall af kopar nær nær yfir 98% og vilja ekki orsök allir mengun til the umhverfi.

In order to promote this new type of water supply pipe, the Ministry of Construction, the Water Supply and Drainage Committee of the China Engineering Standardization Association, and the Standard Quota Department of the Ministry of Construction have done corresponding work, including specifying the national standard "Copper Pipe Fittings" GB11618.1~8 for copper pipe fittings. -89. In order to better meet the requirements of the construction industry, based on careful research, we also participated in the designation of the Ministry of Construction distribution standard "Copper Pipe Fittings for Construction" JG/T3031.1~8-1996. In the water supply and drainage design specifications, it is also clear that domestic water supply pipes "should be copper pipes in buildings with high usage requirements." These standards and specifications are formulated with full consideration of various situations. These all illustrate that copper pipes used in domestic water supply are not only non-toxic, but also advanced pipes.

Í röð til framkvæma það, að Ráðuneyti af Byggingarstarfsemi og fjórum öðru ráðuneyti (Ráðuneyti af Byggingarstarfsemi, Ríki Efnahagsmál og Viðskipti Þóknun, Tæknileg Eftirlit Skrifstofa, og Byggingar Efni Skrifstofa) sameiginlega kynnt á "Tilkynning á á brotthvarf af úrelt vörur í íbúðarhúsnæði framkvæmdir" á desember 13, 1999 (Byggingar Húsnæði [1999 ] No. 295), frekari skýrt skýrt tekið fram að að notkun af kopar pípur get einnig vera kynnt þar skilyrði leyfi.

In August 2000, the Science and Technology Department of the Ministry of Construction and the Planning and Development Department of the National Nonferrous Metals Industry Bureau jointly held a seminar on the promotion and application of copper pipes in Beijing. Later, the Ministry of Construction proposed to gradually promote the application of copper pipes in building water supply projects. First of all, it is adopted in the hot water supply system of hotel-type buildings, and the application fields are continuously broadened; it is also recommended to build sites in Shanghai, Beijing, Chongqing, Guangdong, Sichuan, Hubei, Fujian, Jiangsu, Zhejiang, Henan and other provinces and cities to gradually demonstrate promotion. In 2003, in order to strengthen the coordinated development of the production and application of construction steel, copper, and aluminum, the Ministry of Construction and the State Economic and Trade Commission established a corresponding working system, with the purpose of coordinating relevant departments and relevant units to jointly promote the production and application of construction metals. Research, develop, promote and apply technologies and products, accelerate the industrialization process, coordinate the formulation of technical policies and development plans, and promote the coordinated and healthy development of the industry. It also issued the "Notice on the Establishment of the "National Joint Conference on Coordination of Metal Technology and Application in Construction" (Jianbanke [2003] No. 3), which clarified the organizational form of the joint conference and formulated a work plan. This includes efforts to promote the application of copper water pipes in mid- to high-end buildings.

Í 2002, the fyrrverandi ríki efnahagsleg og verslun þóknun útgefið the "Nýleg þróun stefnumörkun af í iðnaði iðnaði" skýrslu, krefjast þróunar af kopar vinnslu vörur með vörur vörur með vöru markaði horfur, þar á meðal kopar vatn rör.

On May 15, 2017, the Ministry of Housing and Urban-Rural Development issued the industry standard "Technical Regulations for Pipeline Direct Drinking Water Systems in Buildings and Residential Areas" requiring that pipes should be copper pipes and other high-quality pipes that meet food-grade requirements.

Á mars 13, 2019, á ráðuneyti af Húsnæði og Þéttbýlis-dreifbýli þróun útgefið að þjóðarstaðall "Grænn Bygging Mat Staðall", sem verð verður hrint í framkvæmd á ágúst 1, 2019; það kveður á um að innandyra vatn vatnsveitu kerfi ætti að nota kopar pípur það eru tæringarþolnar, and hafa gott tæringu viðnám.
