浙江(jiang)至德鋼(gang)(gang)(gang)業有(you)限公司(si)技術(shu)人員了解到(dao)國外某海邊新建工(gong)廠，工(gong)廠用(yong)(yong)水(shui)是由海水(shui)除(chu)氯(lv)離子后使(shi)用(yong)(yong)，配管(guan)設(she)計人員認為已經增加了配套(tao)的除(chu)氯(lv)離子裝置，選用(yong)(yong)普通碳(tan)鋼(gang)(gang)(gang)管(guan)子，并(bing)布置在地面上。但是，根據所(suo)在國家的規范條文解釋描述，這種海水(shui)除(chu)氯(lv)離子水(shui)并(bing)非全部除(chu)去(qu)了氯(lv)離子，不(bu)能選用(yong)(yong)普通碳(tan)鋼(gang)(gang)(gang)管(guan)道(dao)(dao)，必(bi)須使(shi)用(yong)(yong)玻(bo)璃鋼(gang)(gang)(gang)管(guan)道(dao)(dao)。因詳細設(she)計已經進行(xing)到(dao)80％階段，不(bu)宜再埋地敷(fu)設(she)玻(bo)璃鋼(gang)(gang)(gang)管(guan)道(dao)(dao)，配管(guan)設(she)計人員認為玻(bo)璃鋼(gang)(gang)(gang)管(guan)道(dao)(dao)如果在地上敷(fu)設(she)則管(guan)材(cai)易老化。

  但是，根(gen)據(ju)AWWA M45《玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)(guan)設計規(gui)(gui)范(fan)》、AWWA C950-01《玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)壓力(li)管(guan)(guan)(guan)道(dao)(dao)》、API Spec 15LR《低壓玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)(guan)道(dao)(dao)和管(guan)(guan)(guan)件》、API Spec 15HR《高壓玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)管(guan)(guan)(guan)線管(guan)(guan)(guan)規(gui)(gui)范(fan)》、APIRP 15TL4《玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)管(guan)(guan)(guan)的(de)維(wei)護與使用推薦(jian)作法》、ASTM D2996-01《長絲(si)纏繞(rao)玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)（玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)增強(qiang)(qiang)熱(re)固(gu)(gu)性樹(shu)脂）管(guan)(guan)(guan)道(dao)(dao)標(biao)準規(gui)(gui)范(fan)》、ASTM D2992《玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)（增強(qiang)(qiang)的(de)熱(re)固(gu)(gu)樹(shu)脂玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)）管(guan)(guan)(guan)及配件用液體靜壓設計基礎標(biao)準實施規(gui)(gui)程》、ASTM D2996-01《長絲(si)纏繞(rao)玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)（玻(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)增強(qiang)(qiang)熱(re)固(gu)(gu)性樹(shu)脂）管(guan)(guan)(guan)道(dao)(dao)標(biao)準規(gui)(gui)范(fan)》等(deng)規(gui)(gui)范(fan)，玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)(guan)道(dao)(dao)完全可以布置在(zai)地面上，可以選用不怕(pa)太(tai)陽直曬的(de)玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)(guan)道(dao)(dao)。玻(bo)璃(li)(li)鋼(gang)(gang)(gang)管(guan)(guan)(guan)道(dao)(dao)的(de)質量約是普(pu)通(tong)碳(tan)鋼(gang)(gang)(gang)的(de)20％～30％，熱(re)膨脹系數是普(pu)通(tong)碳(tan)鋼(gang)(gang)(gang)管(guan)(guan)(guan)道(dao)(dao)的(de)3倍左右。
