    FF: Simbi yakafa zvizere ine zvinhu zvinosunga nitrogen muhuwandu hwakakwana kuti isunge nitrogen iripo (semuenzaniso 0,020% yeAl yose kana 0,015% yeAl inonyungudika).
    b. Kukosha kwakanyanya kwenitrogen hakushandi kana makemikari ari muchikamu ichi achiratidza huwandu hweAl hushoma hwe0,020% nechiyero cheAl/N che2:1, kana kana paine zvimwe zvinhu zveN-binding zvakakwana. Zvinhu zveN-binding zvinofanira kunyorwa muGwaro reKuongorora.

    Maitiro ekugadzira

    Pombi yakasungirirwa inotenderera, inozivikanwawo seSSAW (spiral submerged arc welded) pipe, inogadzirwa uchishandisa nzira dzekugadzira spiral uye submerged arc welding. Maitiro acho anotanga nekurapa strip yesimbi yakamonerwa uye wobva wakombamisa strip kuita spiral shape. Kubatanidza otomatiki arc welding kunoshandiswa kubatanidza mipendero yemipendero pamwe chete, zvichigadzira weld inoenderera mberi muhurefu hwepombi. Nzira iyi inoita kuti joint irambe yakasimba uye yakasimba uku ichideredza zvikanganiso uye ichichengetedza chimiro chayo.

    Mabhenefiti epombi yesimbi yekabhoni yakasungirirwa nesimbi inotenderera

    1. Simba uye kugara kwenguva refu:Spiral welded kabhoni simbi mutopotainozivikanwa nekusimba kwayo kwakanyanya uye kugara kwenguva refu, zvichiita kuti ikwanise kushandiswa inoda kuramba kumanikidzwa kwakanyanya uye kushanda kwenguva refu.

    2. Kushanda Nemutengo Wakanaka: Mapaipi aya anopa mhinduro isingadhuri nekuda kwemaitiro awo ekugadzira anoshanda zvakanaka, mitengo yakaderera yezvinhu zvakagadzirwa, uye kudiwa kwevashandi kwakaderera zvichienzaniswa nemamwe marudzi emapaipi.

    3. Kuchinja-chinja: Kuchinja-chinja kwepombi yesimbi yekabhoni yakasungirirwa nesimbi inotenderera kunoita kuti ikwanise kushandiswa mumabasa akasiyana-siyana, kusanganisira kutakurwa kwemvura, kutakurwa kwemafuta negasi, zvivakwa zvekuunganidzira, masisitimu etsvina, uye maitiro akasiyana-siyana emaindasitiri.

    4. Kururama kwemativi: Maitiro ekugadzira spiral anogona kudzora saizi nemadziro epombi nemazvo, zvichiita kuti pave nekurongeka uye kufanana kwekugadzirwa.

    Kushongedza Arc Yakanyudzwa neHelical

    Nzvimbo dzekushandisa

    1. Indasitiri yemafuta negasi rechisikigo: Mapaipi esimbi ecarbon akasungirirwa nesimbi anoshandiswa zvakanyanya muindasitiri yemafuta negasi rechisikigo, kunyanya mukutakura mafuta asina kucheneswa, gasi rechisikigo nezvigadzirwa zvepeturu. Simba rawo nekukwanisa kwawo kutsungirira mamiriro ekumanikidzwa kwakanyanya zvinoita kuti akwanise kushandiswa pamapaipi ari kure.

    2. Kutakura Mvura: Ingave yekupa mvura yemumaguta kana yekudiridza, mapaipi esimbi ecarbon anosungirirwa nesimbi anopa mhinduro yakanaka nekuda kwekusagona ngura, kusimba uye nyore kuisa.

    3. Rutsigiro rwechivakwa: Rudzi urwu rwepombi runoshandiswa zvakanyanya muindasitiri yekuvaka kupa rutsigiro rwechivakwa chezvivakwa, mabhiriji, madoko nemamwe mapurojekiti ezvivakwa. Kugara kwenguva refu kwavo uye kuramba kwavo zvinhu zvekunze zvinoita kuti vavimbike mukushandiswa kwakadaro.

    4. Mashandisirwo Emaindasitiri: Mapaipi esimbi yekabhoni akasungirirwa nesimbi anoshandiswa muzvikamu zvakasiyana-siyana zvemaindasitiri zvakaita sekugadzira makemikari, mafekitori emagetsi uye mabasa ekuchera migodhi nekuda kwekugona kwawo kubata tembiricha yakakwira, kumanikidzwa uye nharaunda dzinopisa.

    Mukupedzisa

    Pombi yesimbi yekabhoni yakasungirirwa nesimbi yakasungirirwa, sengePombi yeX42 SSAW, yakachinja maitiro ekunamira mapaipi esimbi, zvichiunza mabhenefiti akawanda kumaindasitiri akasiyana. Simba rayo, kugara kwenguva refu, kushanda zvakanaka kwemari uye kurongeka kwehukuru hwayo zvinovimbisa kusimba kwechimiro mukushandiswa kwakasiyana-siyana. Kukwanisa kutsungirira kumanikidzwa kwakanyanya, tembiricha nenzvimbo dzinopisa zvinoita kuti ive yakakodzera kutapurirana mafuta negasi, kuwanikwa kwemvura nedzimwe nzvimbo dzemaindasitiri. Saka, kana zvasvika pakunamira mapaipi esimbi, kushandiswa kwemapaipi esimbi esimbi akasungirirwa nesimbi inotenderera kunoramba kuri mhinduro yakavimbika uye inoshanda yekuona kuti zvivakwa zvinogara kwenguva refu uye zvinogara kwenguva refu.

    Kuedzwa kweHydrostatic

    Kureba kwepaipi imwe neimwe kunofanira kuyedzwa nemugadziri kusvika pakumanikidzwa kwemvura kuchaita kuti pamadziro epaipi pave nekumanikidzwa kusingasviki 60% yesimba remubereko rakatarwa patembiricha yemumba. Kumanikidzwa kunofanira kutsanangurwa nemuenzaniso unotevera:

    Kusiyana Kunobvumidzwa Muhuremu neMakuriro

    Kureba kwepombi imwe neimwe kunofanira kuyerwa zvakasiyana uye huremu hwayo hahufanirwe kusiyana ne10% pamusoro kana 5.5% pasi pehuremu hwayo hwepfungwa, zvichiverengerwa uchishandisa hurefu hwayo nehuremu hwayo pahurefu hweyuniti imwe neimwe.
    Dhayamita yekunze haifanirwe kusiyana kupfuura ±1% kubva padhayamita yekunze yakatarwa.
