據湖(hu)南省長(chang)(chang)(chang)沙(sha)(sha)市(shi)住(zhu)房和城(cheng)鄉建設委(wei)員會消息，為貫徹長(chang)(chang)(chang)沙(sha)(sha)市(shi)委(wei)、市(shi)政府提出(chu)的(de)(de)(de)(de)建設國家中心城(cheng)市(shi)和品質長(chang)(chang)(chang)沙(sha)(sha)的(de)(de)(de)(de)要求(qiu)，進(jin)一(yi)步確(que)保長(chang)(chang)(chang)沙(sha)(sha)市(shi)的(de)(de)(de)(de)供水安全可(ke)靠度(du)和進(jin)一(yi)步提高長(chang)(chang)(chang)沙(sha)(sha)市(shi)的(de)(de)(de)(de)供水水質，有效提高長(chang)(chang)(chang)沙(sha)(sha)市(shi)民的(de)(de)(de)(de)健康(kang)生(sheng)活水平，該委(wei)于2017年(nian)8月(yue)2日發(fa)布了新的(de)(de)(de)(de)《住(zhu)宅(zhai)供水技(ji)術(shu)導(dao)則(ze)》（下(xia)稱(cheng)《導(dao)則(ze)》）。結合長(chang)(chang)(chang)沙(sha)(sha)市(shi)實(shi)際情況對原《長(chang)(chang)(chang)沙(sha)(sha)市(shi)建筑(zhu)供水一(yi)戶一(yi)表及二次供水技(ji)術(shu)導(dao)則(ze)（試行）》進(jin)行了全面(mian)修訂(ding)。新《導(dao)則(ze)》將于2017年(nian)11月(yue)1日起(qi)正式實(shi)施。隨著(zhu)新《導(dao)則(ze)》的(de)(de)(de)(de)實(shi)施，長(chang)(chang)(chang)沙(sha)(sha)市(shi)的(de)(de)(de)(de)城(cheng)市(shi)管(guan)網系統將有望全面(mian)迎來不(bu)銹鋼給水管(guan)時代。據了解(jie)，長(chang)(chang)(chang)沙(sha)(sha)市(shi)是(shi)繼深圳市(shi)后(hou)，以(yi)政府主管(guan)部門文件形式對管(guan)道材(cai)料(liao)進(jin)行明確(que)規(gui)定的(de)(de)(de)(de)城(cheng)市(shi)。

 值得一提的(de)是，該《導則》的(de)第八章，對管(guan)(guan)(guan)(guan)材(cai)(cai)及(ji)配(pei)件做出(chu)了明(ming)確規(gui)定(ding)(ding)。如：生(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)系(xi)統采(cai)(cai)用(yong)(yong)(yong)(yong)的(de)管(guan)(guan)(guan)(guan)材(cai)(cai)、配(pei)件應(ying)(ying)(ying)符合國(guo)家標(biao)準的(de)規(gui)定(ding)(ding)；小(xiao)區(qu)室外(wai)(wai)給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)埋地管(guan)(guan)(guan)(guan)道(dao)DN＜100mm的(de)生(sheng)活給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道(dao)及(ji)配(pei)件均(jun)應(ying)(ying)(ying)采(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以上等(deng)級不(bu)(bu)銹(xiu)鋼材(cai)(cai)質(zhi)；不(bu)(bu)銹(xiu)鋼管(guan)(guan)(guan)(guan)的(de)壁厚應(ying)(ying)(ying)根(gen)(gen)據工程地質(zhi)條(tiao)件、荷載、安裝環境、使用(yong)(yong)(yong)(yong)壓力(li)等(deng)確定(ding)(ding)；小(xiao)區(qu)室外(wai)(wai)給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道(dao)至(zhi)泵房生(sheng)活飲用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)箱及(ji)泵房內(nei)生(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)系(xi)統管(guan)(guan)(guan)(guan)道(dao)的(de)管(guan)(guan)(guan)(guan)材(cai)(cai)與配(pei)件應(ying)(ying)(ying)采(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以上等(deng)級不(bu)(bu)銹(xiu)鋼材(cai)(cai)質(zhi)；小(xiao)區(qu)市(shi)政直供生(sheng)活飲用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)系(xi)統非埋地給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道(dao)的(de)管(guan)(guan)(guan)(guan)材(cai)(cai)及(ji)配(pei)件應(ying)(ying)(ying)采(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以上等(deng)級不(bu)(bu)銹(xiu)鋼材(cai)(cai)質(zhi)；二次加壓設施至(zhi)用(yong)(yong)(yong)(yong)戶水(shui)(shui)(shui)(shui)(shui)表(biao)前(qian)給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道(dao)的(de)管(guan)(guan)(guan)(guan)材(cai)(cai)與配(pei)件應(ying)(ying)(ying)采(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以上等(deng)級不(bu)(bu)銹(xiu)鋼材(cai)(cai)質(zhi)；生(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)給(gei)(gei)水(shui)(shui)(shui)(shui)(shui)系(xi)統進水(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)和出(chu)水(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)宜作藍色(se)色(se)標(biao)，并(bing)以文(wen)字(zi)表(biao)示高、中(zhong)、低壓力(li)分區(qu)，用(yong)(yong)(yong)(yong)箭頭標(biao)明(ming)水(shui)(shui)(shui)(shui)(shui)流方向。水(shui)(shui)(shui)(shui)(shui)流方向及(ji)加壓分區(qu)的(de)標(biao)識間距不(bu)(bu)大于5m；埋地的(de)不(bu)(bu)銹(xiu)鋼管(guan)(guan)(guan)(guan)應(ying)(ying)(ying)根(gen)(gen)據土質(zhi)和環境條(tiao)件采(cai)(cai)取合適的(de)防腐(fu)措施。

 從上文可以明(ming)(ming)(ming)顯(xian)看到，新《導則(ze)》對管道應(ying)用的措辭明(ming)(ming)(ming)確，均以“應(ying)”這個(ge)字眼(yan)做出明(ming)(ming)(ming)確規定，其中“S304以上等級不(bu)銹(xiu)鋼”亦(yi)處于明(ming)(ming)(ming)顯(xian)的突出位(wei)置(zhi)。長沙有關方面(mian)的態度(du)和力度(du)可謂(wei)是鮮明(ming)(ming)(ming)且不(bu)含糊，模棱兩可、混水摸(mo)魚(yu)的工程商(shang)(shang)或供(gong)應(ying)商(shang)(shang)將無(wu)機(ji)可乘。

 近年來(lai)，飲(yin)用(yong)水管(guan)(guan)(guan)的(de)(de)質量問(wen)題引起了(le)央視(shi)等主流媒體和(he)政(zheng)府(fu)有關職能部門的(de)(de)關注和(he)重視(shi)，不(bu)銹鋼水管(guan)(guan)(guan)憑借其他材質如(ru)銅管(guan)(guan)(guan)、鍍鋅管(guan)(guan)(guan)、塑(su)料管(guan)(guan)(guan)等難(nan)以(yi)比擬的(de)(de)優勢而日(ri)益受(shou)到工程商、經銷商和(he)消(xiao)費者的(de)(de)關注、歡(huan)迎和(he)青睞(lai)。可以(yi)想(xiang)見(jian)的(de)(de)是(shi)，未來(lai)除了(le)深圳、長沙(sha)外，必(bi)將(jiang)會有越來(lai)越多的(de)(de)地方出臺相應(ying)的(de)(de)政(zheng)策措(cuo)施(shi)推(tui)廣不(bu)銹鋼水管(guan)(guan)(guan)的(de)(de)應(ying)用(yong)。值(zhi)得一提(ti)的(de)(de)是(shi)，目前在國內的(de)(de)廣東、四(si)川、浙江等地已涌現一批具有品牌(pai)優勢和(he)規模實力且深耕不(bu)銹鋼水管(guan)(guan)(guan)市場多年的(de)(de)企業。

 隨著環保理念(nian)的逐步加強，不銹鋼水管必(bi)將(jiang)在未來幾年內強勢(shi)襲來！
