浙(zhe)江至德鋼(gang)業有(you)限公司技術人員了解到國外某海(hai)(hai)邊新(xin)建工廠，工廠用(yong)水(shui)是(shi)由(you)海(hai)(hai)水(shui)除氯(lv)離(li)(li)子(zi)后使用(yong)，配(pei)管設計人員認(ren)為已(yi)(yi)經(jing)增加了配(pei)套的除氯(lv)離(li)(li)子(zi)裝置，選(xuan)用(yong)普通(tong)碳鋼(gang)管子(zi)，并(bing)(bing)布(bu)置在(zai)(zai)(zai)地(di)面(mian)上(shang)。但(dan)是(shi)，根據所(suo)在(zai)(zai)(zai)國家的規范條文解釋描述，這種海(hai)(hai)水(shui)除氯(lv)離(li)(li)子(zi)水(shui)并(bing)(bing)非全部除去了氯(lv)離(li)(li)子(zi)，不能(neng)選(xuan)用(yong)普通(tong)碳鋼(gang)管道(dao)，必(bi)須使用(yong)玻(bo)璃(li)鋼(gang)管道(dao)。因詳細設計已(yi)(yi)經(jing)進行到80％階段，不宜再埋地(di)敷(fu)設玻(bo)璃(li)鋼(gang)管道(dao)，配(pei)管設計人員認(ren)為玻(bo)璃(li)鋼(gang)管道(dao)如果在(zai)(zai)(zai)地(di)上(shang)敷(fu)設則管材易老化。

  但是，根據AWWA M45《玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)管(guan)設計規范(fan)(fan)》、AWWA C950-01《玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)壓力管(guan)道(dao)(dao)(dao)》、API Spec 15LR《低壓玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)管(guan)道(dao)(dao)(dao)和管(guan)件(jian)》、API Spec 15HR《高壓玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)管(guan)線(xian)管(guan)規范(fan)(fan)》、APIRP 15TL4《玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)管(guan)的(de)(de)維(wei)(wei)(wei)(wei)護與使用(yong)推薦作法》、ASTM D2996-01《長絲纏繞(rao)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)（玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)增強熱(re)固(gu)性樹脂）管(guan)道(dao)(dao)(dao)標(biao)(biao)準規范(fan)(fan)》、ASTM D2992《玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)（增強的(de)(de)熱(re)固(gu)樹脂玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)）管(guan)及配件(jian)用(yong)液(ye)體(ti)靜壓設計基礎標(biao)(biao)準實施規程》、ASTM D2996-01《長絲纏繞(rao)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)（玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)維(wei)(wei)(wei)(wei)增強熱(re)固(gu)性樹脂）管(guan)道(dao)(dao)(dao)標(biao)(biao)準規范(fan)(fan)》等(deng)規范(fan)(fan)，玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)管(guan)道(dao)(dao)(dao)完全可以布(bu)置在地面(mian)上(shang)，可以選用(yong)不(bu)怕(pa)太陽直曬的(de)(de)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)管(guan)道(dao)(dao)(dao)。玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)管(guan)道(dao)(dao)(dao)的(de)(de)質(zhi)量約是普通碳鋼(gang)的(de)(de)20％～30％，熱(re)膨脹系(xi)數是普通碳鋼(gang)管(guan)道(dao)(dao)(dao)的(de)(de)3倍左右(you)。
