浙江至德鋼(gang)(gang)(gang)業(ye)有(you)限公(gong)司技術人(ren)(ren)(ren)員(yuan)(yuan)了(le)解(jie)到國(guo)(guo)外某海邊(bian)新建工(gong)廠，工(gong)廠用水(shui)是由海水(shui)除氯(lv)離子(zi)(zi)(zi)后使用，配(pei)管(guan)(guan)設(she)計人(ren)(ren)(ren)員(yuan)(yuan)認為已經(jing)增(zeng)加了(le)配(pei)套的(de)除氯(lv)離子(zi)(zi)(zi)裝置，選用普通碳鋼(gang)(gang)(gang)管(guan)(guan)子(zi)(zi)(zi)，并布置在地面上。但是，根據(ju)所在國(guo)(guo)家的(de)規范條文解(jie)釋(shi)描述，這(zhe)種海水(shui)除氯(lv)離子(zi)(zi)(zi)水(shui)并非全部除去了(le)氯(lv)離子(zi)(zi)(zi)，不能選用普通碳鋼(gang)(gang)(gang)管(guan)(guan)道(dao)，必須使用玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)道(dao)。因(yin)詳細設(she)計已經(jing)進行(xing)到80％階(jie)段，不宜再埋地敷設(she)玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)道(dao)，配(pei)管(guan)(guan)設(she)計人(ren)(ren)(ren)員(yuan)(yuan)認為玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)道(dao)如果在地上敷設(she)則管(guan)(guan)材易(yi)老化。
