據湖(hu)南(nan)省長沙市(shi)(shi)住房和城(cheng)鄉建(jian)設委(wei)員會消息，為貫徹長沙市(shi)(shi)委(wei)、市(shi)(shi)政府提出的建(jian)設國家中(zhong)心城(cheng)市(shi)(shi)和品質長沙的要(yao)求，進(jin)一步確保長沙市(shi)(shi)的供(gong)水(shui)安全(quan)可靠度和進(jin)一步提高長沙市(shi)(shi)的供(gong)水(shui)水(shui)質，有效提高長沙市(shi)(shi)民的健康生活水(shui)平，該委(wei)于(yu)2017年8月2日(ri)發布了新的《住宅供(gong)水(shui)技術(shu)(shu)導則(ze)》（下(xia)稱《導則(ze)》）。結合長沙市(shi)(shi)實際(ji)情(qing)況(kuang)對(dui)原(yuan)《長沙市(shi)(shi)建(jian)筑供(gong)水(shui)一戶一表(biao)及(ji)二次供(gong)水(shui)技術(shu)(shu)導則(ze)（試行）》進(jin)行了全(quan)面(mian)(mian)修訂(ding)。新《導則(ze)》將于(yu)2017年11月1日(ri)起正式實施(shi)。隨著新《導則(ze)》的實施(shi)，長沙市(shi)(shi)的城(cheng)市(shi)(shi)管網(wang)系統將有望全(quan)面(mian)(mian)迎來不銹鋼給水(shui)管時代。據了解(jie)，長沙市(shi)(shi)是繼深圳市(shi)(shi)后(hou)，以政府主管部門文件形式對(dui)管道材料進(jin)行明確規定的城(cheng)市(shi)(shi)。

 值得一提的(de)(de)(de)(de)是，該《導則》的(de)(de)(de)(de)第八(ba)章，對管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)及配(pei)件(jian)(jian)做出了明確規(gui)定(ding)。如：生(sheng)(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)給水(shui)(shui)系統(tong)(tong)采(cai)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)、配(pei)件(jian)(jian)應(ying)(ying)(ying)符合國家標(biao)準的(de)(de)(de)(de)規(gui)定(ding)；小區(qu)(qu)室外給水(shui)(shui)埋(mai)(mai)地管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)DN＜100mm的(de)(de)(de)(de)生(sheng)(sheng)活給水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)及配(pei)件(jian)(jian)均應(ying)(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)鋼(gang)材(cai)(cai)質(zhi)；不(bu)銹(xiu)(xiu)(xiu)鋼(gang)管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)壁厚應(ying)(ying)(ying)根據工程地質(zhi)條件(jian)(jian)、荷載、安裝環境(jing)、使用(yong)(yong)(yong)(yong)壓(ya)力等確定(ding)；小區(qu)(qu)室外給水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)至泵(beng)房生(sheng)(sheng)活飲(yin)(yin)用(yong)(yong)(yong)(yong)水(shui)(shui)水(shui)(shui)箱及泵(beng)房內(nei)生(sheng)(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)給水(shui)(shui)系統(tong)(tong)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)與配(pei)件(jian)(jian)應(ying)(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)鋼(gang)材(cai)(cai)質(zhi)；小區(qu)(qu)市政直供生(sheng)(sheng)活飲(yin)(yin)用(yong)(yong)(yong)(yong)水(shui)(shui)系統(tong)(tong)非埋(mai)(mai)地給水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)及配(pei)件(jian)(jian)應(ying)(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)鋼(gang)材(cai)(cai)質(zhi)；二次加壓(ya)設施至用(yong)(yong)(yong)(yong)戶水(shui)(shui)表前(qian)給水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)與配(pei)件(jian)(jian)應(ying)(ying)(ying)采(cai)用(yong)(yong)(yong)(yong)（S304）以(yi)(yi)上等級(ji)不(bu)銹(xiu)(xiu)(xiu)鋼(gang)材(cai)(cai)質(zhi)；生(sheng)(sheng)活用(yong)(yong)(yong)(yong)水(shui)(shui)給水(shui)(shui)系統(tong)(tong)進水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)和(he)出水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)宜(yi)作(zuo)藍色(se)色(se)標(biao)，并以(yi)(yi)文字表示(shi)高、中(zhong)、低壓(ya)力分區(qu)(qu)，用(yong)(yong)(yong)(yong)箭(jian)頭標(biao)明水(shui)(shui)流(liu)方(fang)向。水(shui)(shui)流(liu)方(fang)向及加壓(ya)分區(qu)(qu)的(de)(de)(de)(de)標(biao)識間距不(bu)大于(yu)5m；埋(mai)(mai)地的(de)(de)(de)(de)不(bu)銹(xiu)(xiu)(xiu)鋼(gang)管(guan)(guan)(guan)(guan)(guan)應(ying)(ying)(ying)根據土質(zhi)和(he)環境(jing)條件(jian)(jian)采(cai)取合適(shi)的(de)(de)(de)(de)防腐措施。

 從上文可(ke)(ke)(ke)以(yi)明(ming)(ming)顯看(kan)到，新(xin)《導則》對管道(dao)應用(yong)的措辭(ci)明(ming)(ming)確，均以(yi)“應”這個字眼做出明(ming)(ming)確規定，其中“S304以(yi)上等級不銹鋼(gang)”亦處于明(ming)(ming)顯的突出位置。長沙有關方面的態(tai)度(du)和力度(du)可(ke)(ke)(ke)謂是鮮明(ming)(ming)且不含糊，模(mo)棱兩可(ke)(ke)(ke)、混水摸(mo)魚的工程商或供應商將無機可(ke)(ke)(ke)乘。

 近年來，飲(yin)用水管的(de)(de)(de)(de)質量問題引起了(le)央(yang)視(shi)等(deng)(deng)主(zhu)流媒體和(he)(he)政(zheng)(zheng)府有關(guan)職能部(bu)門的(de)(de)(de)(de)關(guan)注和(he)(he)重視(shi)，不銹鋼(gang)(gang)水管憑借其(qi)他(ta)材質如銅管、鍍鋅管、塑料管等(deng)(deng)難以比擬(ni)的(de)(de)(de)(de)優勢而(er)日益(yi)受到工程商、經銷商和(he)(he)消費者的(de)(de)(de)(de)關(guan)注、歡迎和(he)(he)青睞。可以想(xiang)見的(de)(de)(de)(de)是，未來除了(le)深圳、長沙外，必將會(hui)有越來越多的(de)(de)(de)(de)地(di)方出臺(tai)相(xiang)應的(de)(de)(de)(de)政(zheng)(zheng)策措施推廣不銹鋼(gang)(gang)水管的(de)(de)(de)(de)應用。值(zhi)得(de)一提的(de)(de)(de)(de)是，目(mu)前在國內的(de)(de)(de)(de)廣東(dong)、四川(chuan)、浙江等(deng)(deng)地(di)已涌現一批具(ju)有品牌優勢和(he)(he)規模(mo)實力(li)且深耕不銹鋼(gang)(gang)水管市場多年的(de)(de)(de)(de)企業(ye)。

 隨著(zhu)環保理念的逐(zhu)步加強，不銹鋼(gang)水管必將在未來(lai)幾年內強勢(shi)襲來(lai)！
