    Imibhobho yeSpiral eWelded Carbon Steel yeMibhobho yeGesi yeNdalo engaphantsi komhlaba- EN10219 Umfanekiso obonakalayo
    • Imibhobho yeSpiral eWelded Carbon Steel yeMibhobho yeGesi yeNdalo engaphantsi komhlaba - EN10219

    Inkcazelo emfutshane:

    Ukwazisa i-spiral welded carbon steel pipe kwizicelo zemibhobho yerhasi yendalo ephantsi komhlaba. Lo mbhobho womgangatho ophezulu uhambelana nemigangatho ye-EN10219 kwaye unikezela ngoluhlu lweenzuzo kwiintlobo ezahlukeneyo zokusetyenziswa kwezoshishino kunye nezorhwebo.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Enye yeenzuzo eziphambili zespiral welded carbon steel umbhobhokukukwazi ukuvelisa imibhobho yobubanzi obuhlukeneyo kusetyenziswa imicu yobubanzi obufanayo. Oku kunenzuzo ngakumbi kwizicelo ezifuna imicu emxinwa yentsimbi ukuvelisa imibhobho yentsimbi enobubanzi obukhulu. Le nkqubo yokuvelisa izinto ezintsha iqinisekisa ukuba iibhobho eziveliswayo azigcini nje kuphela kwaye zinamandla, kodwa zinomgangatho ohambelanayo.

    Imibhobho yentsimbi yentsimbi ye-Spiral edityanisiweyo yenzelwe ngokukodwa ukufakelwa kwemibhobho yegesi yendalo ephantsi komhlaba kwaye ithobela iimfuno ezingqongqo zeEN10219. Lo mgangatho uchaza iimfuno zokuhanjiswa kwezobugcisa kumacandelo angaphakathi afakwe kwi-welded welding ye-non-alloy steels kunye ne-fine-grained steels. Umbhobho ke ngoko ukulungele ngokufanelekileyo ukusetyenziswa kwimibhobho yerhasi yendalo engaphantsi komhlaba apho ukuxhathisa umhlwa kunye nokuthembeka kwesakhiwo kubalulekile.

    a. Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding. Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

    Ukongeza kokuguquguquka kwayo ekwenzeni imibhobho yentsimbi enobubanzi obukhulu, imibhobho yentsimbi yekhabhoni edityanisiweyo ibonelela ngezinto ezininzi ezintle. I-teknoloji ye-welding ye-spiral iqinisekisa ukuba umbhobho unomgangatho wangaphakathi ogudileyo, ukunciphisa uxinzelelo kunye nokuphucula iimpawu zokuhamba. Oku kubaluleke kakhulu kwimibhobho yegesi yendalo, apho ukuhamba okusebenzayo nokungathintelekiyo kubaluleke kakhulu ekusebenzeni kakuhle.

    Ukongeza, i-spiral welded carbon steel pipe ixhathisa kakhulu ku-corrosion, iyenza ilungele ukufakwa phantsi komhlaba apho ukuvezwa kokufuma kunye nezinto zomhlaba zinokubeka esichengeni intembeko yombhobho. Ukwakhiwa kwayo eyomeleleyo kunye nezinto ezihlala ixesha elide ziyenza ilungele ukusetyenziswa ixesha elide kwiimeko ezinzima zokusingqongileyo.

    Ukusetyenziswa komgangatho ophezulu wekhabhoni yensimbi kuqinisekisa ukuba imibhobho ineempawu ezibalaseleyo zomatshini, kubandakanywa amandla aphezulu kunye nokuchasana kwempembelelo. Oku kwenza kube lukhetho oluthembekileyoumbhobho wegesi yendalo ongaphantsi komhlabaukufakwa, njengoko imibhobho inokuthi ixhomekeke kwimithwalo yangaphandle kunye nomonakalo onokwenzeka.

    Isishwankathelo, imibhobho yentsimbi ye-spiral edityanisiweyo lolona khetho lungcono kwizicelo zemibhobho yegesi yendalo ephantsi komhlaba. Inkqubo yayo yokuvelisa izinto ezintsha ivumela ukuveliswa kwemibhobho yentsimbi ebanzi ububanzi ukusuka kwimicu emxinwa yentsimbi, iqinisekisa umgangatho ongaguqukiyo kunye nokuqina. Umbhobho uhlangabezana neemfuno zomgangatho we-EN10219 kwaye unokumelana nokugqwesa okugqwesileyo, umphezulu ogudileyo wangaphakathi kunye neempawu zoomatshini ezomeleleyo, oko kuyenza ilungele ukusetyenziswa ixesha elide elithembekileyo kufakelo lombhobho werhasi yendalo ephantsi komhlaba.
