浙江至德鋼(gang)業有(you)限公司技術人(ren)員了(le)解到國外某海邊新建(jian)工廠(chang)，工廠(chang)用(yong)水(shui)是由海水(shui)除(chu)氯(lv)離(li)(li)子(zi)后使用(yong)，配管(guan)設(she)計(ji)人(ren)員認為已(yi)經(jing)增加了(le)配套的除(chu)氯(lv)離(li)(li)子(zi)裝置，選(xuan)用(yong)普(pu)通碳鋼(gang)管(guan)子(zi)，并布置在地(di)面上。但是，根據(ju)所在國家(jia)的規范條文解釋描述，這種海水(shui)除(chu)氯(lv)離(li)(li)子(zi)水(shui)并非全部(bu)除(chu)去了(le)氯(lv)離(li)(li)子(zi)，不能選(xuan)用(yong)普(pu)通碳鋼(gang)管(guan)道，必須使用(yong)玻(bo)璃(li)鋼(gang)管(guan)道。因(yin)詳細設(she)計(ji)已(yi)經(jing)進行到80％階段，不宜再(zai)埋地(di)敷設(she)玻(bo)璃(li)鋼(gang)管(guan)道，配管(guan)設(she)計(ji)人(ren)員認為玻(bo)璃(li)鋼(gang)管(guan)道如果在地(di)上敷設(she)則管(guan)材易老化(hua)。

  但是(shi)，根據(ju)AWWA M45《玻(bo)(bo)(bo)(bo)璃鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)設計(ji)規(gui)(gui)范》、AWWA C950-01《玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)壓(ya)力管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)》、API Spec 15LR《低壓(ya)玻(bo)(bo)(bo)(bo)璃鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)和管(guan)(guan)(guan)(guan)(guan)件》、API Spec 15HR《高(gao)壓(ya)玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)管(guan)(guan)(guan)(guan)(guan)線管(guan)(guan)(guan)(guan)(guan)規(gui)(gui)范》、APIRP 15TL4《玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)管(guan)(guan)(guan)(guan)(guan)的(de)維(wei)護與使(shi)用(yong)推薦作法(fa)》、ASTM D2996-01《長絲纏繞玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)（玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)增強熱固(gu)性樹脂）管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)標準規(gui)(gui)范》、ASTM D2992《玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)（增強的(de)熱固(gu)樹脂玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)）管(guan)(guan)(guan)(guan)(guan)及配件用(yong)液體靜壓(ya)設計(ji)基礎標準實施(shi)規(gui)(gui)程》、ASTM D2996-01《長絲纏繞玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)（玻(bo)(bo)(bo)(bo)璃纖(xian)(xian)維(wei)增強熱固(gu)性樹脂）管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)標準規(gui)(gui)范》等規(gui)(gui)范，玻(bo)(bo)(bo)(bo)璃鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)完全可以(yi)布置在地(di)面(mian)上，可以(yi)選用(yong)不怕太陽直曬的(de)玻(bo)(bo)(bo)(bo)璃鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)。玻(bo)(bo)(bo)(bo)璃鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)的(de)質量約是(shi)普通(tong)碳鋼(gang)(gang)的(de)20％～30％，熱膨脹系數(shu)是(shi)普通(tong)碳鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)道(dao)(dao)的(de)3倍左右。
