浙江至德(de)鋼(gang)(gang)(gang)業有限公司技(ji)術人(ren)員(yuan)了解(jie)到(dao)國外某(mou)海(hai)邊(bian)新建工廠，工廠用(yong)水是(shi)(shi)由海(hai)水除(chu)(chu)氯離子后使用(yong)，配管(guan)設(she)計人(ren)員(yuan)認為已經增(zeng)加了配套的(de)除(chu)(chu)氯離子裝置(zhi)，選用(yong)普通碳(tan)鋼(gang)(gang)(gang)管(guan)子，并布(bu)置(zhi)在(zai)地(di)面上。但是(shi)(shi)，根據(ju)所在(zai)國家的(de)規(gui)范條文解(jie)釋(shi)描述，這種海(hai)水除(chu)(chu)氯離子水并非全(quan)部除(chu)(chu)去了氯離子，不能選用(yong)普通碳(tan)鋼(gang)(gang)(gang)管(guan)道(dao)(dao)，必(bi)須(xu)使用(yong)玻璃(li)鋼(gang)(gang)(gang)管(guan)道(dao)(dao)。因詳細(xi)設(she)計已經進行到(dao)80％階段，不宜再埋地(di)敷設(she)玻璃(li)鋼(gang)(gang)(gang)管(guan)道(dao)(dao)，配管(guan)設(she)計人(ren)員(yuan)認為玻璃(li)鋼(gang)(gang)(gang)管(guan)道(dao)(dao)如果在(zai)地(di)上敷設(she)則管(guan)材易老(lao)化。
