浙江至(zhi)德鋼(gang)業有限公司(si)技術人員(yuan)了(le)解到(dao)國外某海(hai)邊新建工廠(chang)，工廠(chang)用(yong)(yong)水(shui)(shui)是由(you)海(hai)水(shui)(shui)除(chu)氯(lv)離子(zi)(zi)后使(shi)用(yong)(yong)，配(pei)(pei)管(guan)(guan)設計人員(yuan)認為(wei)已經增加了(le)配(pei)(pei)套的除(chu)氯(lv)離子(zi)(zi)裝置，選(xuan)用(yong)(yong)普(pu)通碳(tan)鋼(gang)管(guan)(guan)子(zi)(zi)，并布置在地(di)面上。但是，根(gen)據所在國家的規范條文解釋描述，這種(zhong)海(hai)水(shui)(shui)除(chu)氯(lv)離子(zi)(zi)水(shui)(shui)并非全部除(chu)去(qu)了(le)氯(lv)離子(zi)(zi)，不(bu)(bu)能選(xuan)用(yong)(yong)普(pu)通碳(tan)鋼(gang)管(guan)(guan)道(dao)，必須使(shi)用(yong)(yong)玻璃(li)(li)鋼(gang)管(guan)(guan)道(dao)。因(yin)詳細設計已經進行到(dao)80％階段，不(bu)(bu)宜再埋地(di)敷設玻璃(li)(li)鋼(gang)管(guan)(guan)道(dao)，配(pei)(pei)管(guan)(guan)設計人員(yuan)認為(wei)玻璃(li)(li)鋼(gang)管(guan)(guan)道(dao)如果在地(di)上敷設則管(guan)(guan)材易老化。
