據湖南省長沙(sha)(sha)市(shi)(shi)住(zhu)房(fang)和城鄉(xiang)建(jian)設(she)委(wei)員(yuan)會消(xiao)息，為貫徹長沙(sha)(sha)市(shi)(shi)委(wei)、市(shi)(shi)政府(fu)提(ti)出的(de)(de)(de)建(jian)設(she)國(guo)家中心城市(shi)(shi)和品質(zhi)長沙(sha)(sha)的(de)(de)(de)要求，進(jin)(jin)一步確保長沙(sha)(sha)市(shi)(shi)的(de)(de)(de)供(gong)水(shui)(shui)安全可靠度和進(jin)(jin)一步提(ti)高(gao)長沙(sha)(sha)市(shi)(shi)的(de)(de)(de)供(gong)水(shui)(shui)水(shui)(shui)質(zhi)，有效(xiao)提(ti)高(gao)長沙(sha)(sha)市(shi)(shi)民的(de)(de)(de)健康生活水(shui)(shui)平，該委(wei)于(yu)2017年8月2日(ri)(ri)發布了新的(de)(de)(de)《住(zhu)宅供(gong)水(shui)(shui)技(ji)(ji)術導(dao)則(ze)(ze)》（下(xia)稱(cheng)《導(dao)則(ze)(ze)》）。結(jie)合長沙(sha)(sha)市(shi)(shi)實(shi)際情況對(dui)原《長沙(sha)(sha)市(shi)(shi)建(jian)筑供(gong)水(shui)(shui)一戶一表及二次供(gong)水(shui)(shui)技(ji)(ji)術導(dao)則(ze)(ze)（試行(xing)(xing)）》進(jin)(jin)行(xing)(xing)了全面修訂。新《導(dao)則(ze)(ze)》將于(yu)2017年11月1日(ri)(ri)起正式(shi)實(shi)施。隨著(zhu)新《導(dao)則(ze)(ze)》的(de)(de)(de)實(shi)施，長沙(sha)(sha)市(shi)(shi)的(de)(de)(de)城市(shi)(shi)管(guan)網系統將有望全面迎來不(bu)銹鋼給(gei)水(shui)(shui)管(guan)時代。據了解(jie)，長沙(sha)(sha)市(shi)(shi)是繼深圳市(shi)(shi)后，以政府(fu)主管(guan)部(bu)門文件形(xing)式(shi)對(dui)管(guan)道材料(liao)進(jin)(jin)行(xing)(xing)明確規定的(de)(de)(de)城市(shi)(shi)。

 值(zhi)得(de)一提的(de)(de)是，該(gai)《導(dao)則》的(de)(de)第八章，對管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)(cai)及配(pei)件(jian)(jian)做出(chu)了(le)明確規定。如(ru)：生(sheng)(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)給(gei)(gei)(gei)水(shui)(shui)系(xi)統采(cai)(cai)(cai)用(yong)(yong)(yong)(yong)的(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)(cai)、配(pei)件(jian)(jian)應(ying)符合國家標(biao)(biao)(biao)準的(de)(de)規定；小區室(shi)外給(gei)(gei)(gei)水(shui)(shui)埋地(di)管(guan)(guan)(guan)(guan)(guan)道DN＜100mm的(de)(de)生(sheng)(sheng)活給(gei)(gei)(gei)水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道及配(pei)件(jian)(jian)均應(ying)采(cai)(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)(xiu)鋼材(cai)(cai)(cai)質(zhi)；不(bu)銹(xiu)(xiu)(xiu)(xiu)鋼管(guan)(guan)(guan)(guan)(guan)的(de)(de)壁厚應(ying)根據工程(cheng)地(di)質(zhi)條件(jian)(jian)、荷載、安裝環(huan)(huan)境、使用(yong)(yong)(yong)(yong)壓(ya)力等確定；小區室(shi)外給(gei)(gei)(gei)水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道至泵(beng)房生(sheng)(sheng)活飲(yin)用(yong)(yong)(yong)(yong)水(shui)(shui)水(shui)(shui)箱(xiang)及泵(beng)房內生(sheng)(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)給(gei)(gei)(gei)水(shui)(shui)系(xi)統管(guan)(guan)(guan)(guan)(guan)道的(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)(cai)與配(pei)件(jian)(jian)應(ying)采(cai)(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)(xiu)鋼材(cai)(cai)(cai)質(zhi)；小區市政直供生(sheng)(sheng)活飲(yin)用(yong)(yong)(yong)(yong)水(shui)(shui)系(xi)統非埋地(di)給(gei)(gei)(gei)水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道的(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)(cai)及配(pei)件(jian)(jian)應(ying)采(cai)(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)(xiu)鋼材(cai)(cai)(cai)質(zhi)；二次(ci)加壓(ya)設施至用(yong)(yong)(yong)(yong)戶水(shui)(shui)表(biao)前給(gei)(gei)(gei)水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道的(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)(cai)與配(pei)件(jian)(jian)應(ying)采(cai)(cai)(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)(xiu)鋼材(cai)(cai)(cai)質(zhi)；生(sheng)(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)給(gei)(gei)(gei)水(shui)(shui)系(xi)統進(jin)水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)和出(chu)水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)宜作藍色色標(biao)(biao)(biao)，并(bing)以(yi)文(wen)字表(biao)示高(gao)、中、低(di)壓(ya)力分(fen)區，用(yong)(yong)(yong)(yong)箭頭(tou)標(biao)(biao)(biao)明水(shui)(shui)流方向(xiang)。水(shui)(shui)流方向(xiang)及加壓(ya)分(fen)區的(de)(de)標(biao)(biao)(biao)識間(jian)距不(bu)大(da)于5m；埋地(di)的(de)(de)不(bu)銹(xiu)(xiu)(xiu)(xiu)鋼管(guan)(guan)(guan)(guan)(guan)應(ying)根據土質(zhi)和環(huan)(huan)境條件(jian)(jian)采(cai)(cai)(cai)取(qu)合適的(de)(de)防腐措施。

 從上(shang)文可(ke)以明(ming)(ming)顯看到，新《導則》對管(guan)道應(ying)(ying)用的措辭明(ming)(ming)確，均以“應(ying)(ying)”這個字眼(yan)做出明(ming)(ming)確規定，其(qi)中(zhong)“S304以上(shang)等級不銹鋼”亦處于明(ming)(ming)顯的突出位置。長沙有關方面(mian)的態度和力度可(ke)謂是(shi)鮮明(ming)(ming)且不含糊，模棱兩可(ke)、混(hun)水摸(mo)魚(yu)的工(gong)程商(shang)或(huo)供應(ying)(ying)商(shang)將無機可(ke)乘。

 近年來，飲(yin)用(yong)水(shui)(shui)管(guan)(guan)的(de)(de)質量(liang)問題引起(qi)了(le)央視等主流(liu)媒體和(he)(he)(he)政府有關(guan)職能部門的(de)(de)關(guan)注和(he)(he)(he)重視，不銹鋼水(shui)(shui)管(guan)(guan)憑借其他材質如銅管(guan)(guan)、鍍鋅管(guan)(guan)、塑料(liao)管(guan)(guan)等難以(yi)比(bi)擬的(de)(de)優(you)勢而(er)日益受(shou)到工程商、經銷商和(he)(he)(he)消費者的(de)(de)關(guan)注、歡迎和(he)(he)(he)青睞。可以(yi)想見的(de)(de)是，未(wei)來除了(le)深圳、長(chang)沙外，必將(jiang)會有越來越多(duo)的(de)(de)地方(fang)出(chu)臺(tai)相應的(de)(de)政策(ce)措施(shi)推(tui)廣(guang)(guang)不銹鋼水(shui)(shui)管(guan)(guan)的(de)(de)應用(yong)。值得一(yi)提的(de)(de)是，目前在(zai)國內的(de)(de)廣(guang)(guang)東、四川、浙(zhe)江等地已涌現一(yi)批具有品牌(pai)優(you)勢和(he)(he)(he)規模實力且深耕不銹鋼水(shui)(shui)管(guan)(guan)市場多(duo)年的(de)(de)企業。

 隨著環(huan)保理念的逐步加(jia)強(qiang)，不銹鋼水管(guan)必將(jiang)在未來(lai)幾年(nian)內(nei)強(qiang)勢襲(xi)來(lai)！
