據(ju)湖南省長(chang)沙(sha)(sha)市(shi)住(zhu)房(fang)和城(cheng)鄉建設委員會(hui)消息(xi)，為貫徹長(chang)沙(sha)(sha)市(shi)委、市(shi)政府提出的(de)建設國(guo)家中心城(cheng)市(shi)和品質(zhi)長(chang)沙(sha)(sha)的(de)要求，進一(yi)(yi)步(bu)確(que)保長(chang)沙(sha)(sha)市(shi)的(de)供水(shui)(shui)(shui)安全可靠度和進一(yi)(yi)步(bu)提高長(chang)沙(sha)(sha)市(shi)的(de)供水(shui)(shui)(shui)水(shui)(shui)(shui)質(zhi)，有效提高長(chang)沙(sha)(sha)市(shi)民的(de)健康生活水(shui)(shui)(shui)平(ping)，該委于(yu)2017年(nian)(nian)8月2日(ri)發布(bu)了新(xin)的(de)《住(zhu)宅供水(shui)(shui)(shui)技術導則(ze)》（下稱《導則(ze)》）。結合長(chang)沙(sha)(sha)市(shi)實(shi)際情況對原《長(chang)沙(sha)(sha)市(shi)建筑供水(shui)(shui)(shui)一(yi)(yi)戶一(yi)(yi)表及(ji)二次(ci)供水(shui)(shui)(shui)技術導則(ze)（試行(xing)）》進行(xing)了全面修訂(ding)。新(xin)《導則(ze)》將于(yu)2017年(nian)(nian)11月1日(ri)起正式(shi)實(shi)施(shi)(shi)。隨著(zhu)新(xin)《導則(ze)》的(de)實(shi)施(shi)(shi)，長(chang)沙(sha)(sha)市(shi)的(de)城(cheng)市(shi)管(guan)(guan)網系(xi)統將有望(wang)全面迎來不銹鋼給(gei)水(shui)(shui)(shui)管(guan)(guan)時代。據(ju)了解，長(chang)沙(sha)(sha)市(shi)是繼深圳市(shi)后，以政府主管(guan)(guan)部門(men)文件形式(shi)對管(guan)(guan)道材料進行(xing)明確(que)規定的(de)城(cheng)市(shi)。

 值得一(yi)提的(de)(de)(de)是(shi)，該《導(dao)則》的(de)(de)(de)第八章(zhang)，對管(guan)(guan)(guan)(guan)材(cai)(cai)及(ji)配(pei)件(jian)(jian)做(zuo)出了明(ming)確規定。如(ru)：生活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)(tong)采(cai)用(yong)(yong)(yong)(yong)的(de)(de)(de)管(guan)(guan)(guan)(guan)材(cai)(cai)、配(pei)件(jian)(jian)應(ying)(ying)符合國家標(biao)(biao)準(zhun)的(de)(de)(de)規定；小區室(shi)外(wai)給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)埋地管(guan)(guan)(guan)(guan)道DN＜100mm的(de)(de)(de)生活給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道及(ji)配(pei)件(jian)(jian)均應(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以上(shang)等(deng)(deng)級不(bu)(bu)(bu)銹鋼(gang)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)；不(bu)(bu)(bu)銹鋼(gang)管(guan)(guan)(guan)(guan)的(de)(de)(de)壁厚應(ying)(ying)根據工程地質(zhi)(zhi)(zhi)(zhi)條件(jian)(jian)、荷載、安(an)裝環(huan)境、使用(yong)(yong)(yong)(yong)壓(ya)力(li)等(deng)(deng)確定；小區室(shi)外(wai)給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道至(zhi)泵(beng)房生活飲(yin)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)箱及(ji)泵(beng)房內生活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)(tong)管(guan)(guan)(guan)(guan)道的(de)(de)(de)管(guan)(guan)(guan)(guan)材(cai)(cai)與配(pei)件(jian)(jian)應(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以上(shang)等(deng)(deng)級不(bu)(bu)(bu)銹鋼(gang)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)；小區市政直(zhi)供生活飲(yin)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)(tong)非埋地給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道的(de)(de)(de)管(guan)(guan)(guan)(guan)材(cai)(cai)及(ji)配(pei)件(jian)(jian)應(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以上(shang)等(deng)(deng)級不(bu)(bu)(bu)銹鋼(gang)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)；二次加壓(ya)設施(shi)至(zhi)用(yong)(yong)(yong)(yong)戶水(shui)(shui)(shui)(shui)(shui)(shui)表前給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)道的(de)(de)(de)管(guan)(guan)(guan)(guan)材(cai)(cai)與配(pei)件(jian)(jian)應(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以上(shang)等(deng)(deng)級不(bu)(bu)(bu)銹鋼(gang)材(cai)(cai)質(zhi)(zhi)(zhi)(zhi)；生活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)給(gei)水(shui)(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)(tong)進(jin)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)和(he)出水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)宜作(zuo)藍色(se)色(se)標(biao)(biao)，并以文字表示高、中、低壓(ya)力(li)分(fen)區，用(yong)(yong)(yong)(yong)箭頭標(biao)(biao)明(ming)水(shui)(shui)(shui)(shui)(shui)(shui)流方向(xiang)。水(shui)(shui)(shui)(shui)(shui)(shui)流方向(xiang)及(ji)加壓(ya)分(fen)區的(de)(de)(de)標(biao)(biao)識間距不(bu)(bu)(bu)大于5m；埋地的(de)(de)(de)不(bu)(bu)(bu)銹鋼(gang)管(guan)(guan)(guan)(guan)應(ying)(ying)根據土質(zhi)(zhi)(zhi)(zhi)和(he)環(huan)境條件(jian)(jian)采(cai)取合適的(de)(de)(de)防腐措施(shi)。

 從上文可以(yi)明(ming)顯(xian)看到，新《導則》對管道(dao)應用的(de)措辭明(ming)確(que)，均以(yi)“應”這(zhe)個字眼做出(chu)明(ming)確(que)規定(ding)，其(qi)中“S304以(yi)上等級不銹鋼”亦(yi)處于明(ming)顯(xian)的(de)突出(chu)位置(zhi)。長沙有關方面的(de)態度和力度可謂是(shi)鮮(xian)明(ming)且不含糊，模棱兩可、混水摸魚(yu)的(de)工程商或供(gong)應商將無機可乘。

 近(jin)年(nian)來，飲用(yong)水(shui)管(guan)(guan)的(de)(de)(de)質(zhi)量(liang)問題引起了央視(shi)等(deng)主流(liu)媒(mei)體和(he)政府有(you)(you)關職能部門的(de)(de)(de)關注(zhu)和(he)重視(shi)，不(bu)銹鋼水(shui)管(guan)(guan)憑借(jie)其(qi)他材質(zhi)如(ru)銅(tong)管(guan)(guan)、鍍鋅管(guan)(guan)、塑(su)料管(guan)(guan)等(deng)難以(yi)(yi)比(bi)擬的(de)(de)(de)優勢(shi)(shi)而日益受(shou)到工程(cheng)商(shang)、經銷商(shang)和(he)消費者的(de)(de)(de)關注(zhu)、歡迎和(he)青睞。可(ke)以(yi)(yi)想見的(de)(de)(de)是(shi)，未來除了深圳、長沙(sha)外(wai)，必將會有(you)(you)越來越多的(de)(de)(de)地(di)方出臺相應(ying)的(de)(de)(de)政策措施推(tui)廣(guang)不(bu)銹鋼水(shui)管(guan)(guan)的(de)(de)(de)應(ying)用(yong)。值得一提(ti)的(de)(de)(de)是(shi)，目前在國(guo)內(nei)的(de)(de)(de)廣(guang)東、四川、浙江等(deng)地(di)已(yi)涌現(xian)一批(pi)具有(you)(you)品(pin)牌優勢(shi)(shi)和(he)規模實(shi)力(li)且深耕不(bu)銹鋼水(shui)管(guan)(guan)市場多年(nian)的(de)(de)(de)企業。

 隨著(zhu)環保理念的逐(zhu)步加強，不銹鋼水(shui)管必將(jiang)在未(wei)來(lai)幾年內強勢襲來(lai)！
