浙江至德鋼業有(you)限公司技(ji)術人員了(le)解(jie)到(dao)國(guo)外某海邊新建工廠，工廠用(yong)水是由(you)海水除(chu)氯離(li)子(zi)后使用(yong)，配(pei)管(guan)(guan)(guan)設(she)(she)計(ji)人員認為已經(jing)(jing)增加了(le)配(pei)套的除(chu)氯離(li)子(zi)裝(zhuang)置(zhi)，選用(yong)普(pu)通(tong)碳鋼管(guan)(guan)(guan)子(zi)，并(bing)布置(zhi)在(zai)地(di)面上。但是，根據(ju)所在(zai)國(guo)家的規(gui)范(fan)條文解(jie)釋描述，這種海水除(chu)氯離(li)子(zi)水并(bing)非(fei)全部(bu)除(chu)去了(le)氯離(li)子(zi)，不能選用(yong)普(pu)通(tong)碳鋼管(guan)(guan)(guan)道，必須(xu)使用(yong)玻(bo)璃鋼管(guan)(guan)(guan)道。因詳細設(she)(she)計(ji)已經(jing)(jing)進行到(dao)80％階段，不宜再埋地(di)敷設(she)(she)玻(bo)璃鋼管(guan)(guan)(guan)道，配(pei)管(guan)(guan)(guan)設(she)(she)計(ji)人員認為玻(bo)璃鋼管(guan)(guan)(guan)道如果(guo)在(zai)地(di)上敷設(she)(she)則管(guan)(guan)(guan)材易老化。

  但是，根據AWWA M45《玻璃(li)(li)(li)鋼管(guan)(guan)設計(ji)規(gui)(gui)范》、AWWA C950-01《玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)壓力管(guan)(guan)道(dao)(dao)(dao)》、API Spec 15LR《低壓玻璃(li)(li)(li)鋼管(guan)(guan)道(dao)(dao)(dao)和(he)管(guan)(guan)件(jian)(jian)》、API Spec 15HR《高壓玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)管(guan)(guan)線管(guan)(guan)規(gui)(gui)范》、APIRP 15TL4《玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)管(guan)(guan)的(de)(de)維(wei)護(hu)與使用(yong)(yong)推薦作法》、ASTM D2996-01《長(chang)(chang)絲纏繞玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)（玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)增強(qiang)熱(re)(re)(re)固性樹(shu)(shu)脂）管(guan)(guan)道(dao)(dao)(dao)標(biao)準規(gui)(gui)范》、ASTM D2992《玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)（增強(qiang)的(de)(de)熱(re)(re)(re)固樹(shu)(shu)脂玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)）管(guan)(guan)及配件(jian)(jian)用(yong)(yong)液體(ti)靜壓設計(ji)基礎標(biao)準實施規(gui)(gui)程》、ASTM D2996-01《長(chang)(chang)絲纏繞玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)（玻璃(li)(li)(li)纖(xian)(xian)(xian)維(wei)增強(qiang)熱(re)(re)(re)固性樹(shu)(shu)脂）管(guan)(guan)道(dao)(dao)(dao)標(biao)準規(gui)(gui)范》等規(gui)(gui)范，玻璃(li)(li)(li)鋼管(guan)(guan)道(dao)(dao)(dao)完全可以布置在地面上，可以選用(yong)(yong)不(bu)怕(pa)太陽直曬的(de)(de)玻璃(li)(li)(li)鋼管(guan)(guan)道(dao)(dao)(dao)。玻璃(li)(li)(li)鋼管(guan)(guan)道(dao)(dao)(dao)的(de)(de)質(zhi)量約是普(pu)通(tong)(tong)碳鋼的(de)(de)20％～30％，熱(re)(re)(re)膨(peng)脹(zhang)系數是普(pu)通(tong)(tong)碳鋼管(guan)(guan)道(dao)(dao)(dao)的(de)(de)3倍左右。
