浙(zhe)江至德(de)鋼(gang)業有限公(gong)司技(ji)術人員了(le)解到(dao)國外某海邊(bian)新建(jian)工(gong)(gong)廠，工(gong)(gong)廠用(yong)水(shui)(shui)是由海水(shui)(shui)除(chu)氯(lv)離(li)子(zi)后使(shi)用(yong)，配(pei)管(guan)(guan)(guan)設(she)計(ji)(ji)人員認為已經增(zeng)加(jia)了(le)配(pei)套(tao)的除(chu)氯(lv)離(li)子(zi)裝置，選(xuan)用(yong)普通碳(tan)鋼(gang)管(guan)(guan)(guan)子(zi)，并布(bu)置在(zai)地(di)面(mian)上(shang)。但是，根據所(suo)在(zai)國家(jia)的規范條文解釋描述(shu)，這種海水(shui)(shui)除(chu)氯(lv)離(li)子(zi)水(shui)(shui)并非全部除(chu)去了(le)氯(lv)離(li)子(zi)，不能(neng)選(xuan)用(yong)普通碳(tan)鋼(gang)管(guan)(guan)(guan)道(dao)(dao)，必須使(shi)用(yong)玻璃鋼(gang)管(guan)(guan)(guan)道(dao)(dao)。因詳細設(she)計(ji)(ji)已經進(jin)行到(dao)80％階段，不宜再(zai)埋地(di)敷設(she)玻璃鋼(gang)管(guan)(guan)(guan)道(dao)(dao)，配(pei)管(guan)(guan)(guan)設(she)計(ji)(ji)人員認為玻璃鋼(gang)管(guan)(guan)(guan)道(dao)(dao)如果在(zai)地(di)上(shang)敷設(she)則管(guan)(guan)(guan)材(cai)易老化。
