    Pipe yeMusono weSpiral yemhando yepamusoro

    Pipe yeMusono weSpiral yemhando yepamusoro Mufananidzo wakaratidzwa
    • Pipe yeMusono weSpiral yemhando yepamusoro

    Tsananguro pfupi:

    Pombi yedu yemusono yemhando yepamusoro yakakodzera kushandiswa kwakasiyana-siyana, kusanganisira kuvaka, mafuta negesi, uye kutakurwa kwemugungwa. Nesimba rayo guru uye kugara kwenguva refu, yakagadzirirwa kutsungirira kumanikidzwa uye kuramba ngura, zvichiita kuti ive mhinduro inogara kwenguva refu yezvinodiwa zvako zvepombi.


    Ruzivo rweChigadzirwa

    Matagi eChigadzirwa

    Tichiunza pombi yedu yemhando yepamusoro yespiral-seam, chigadzirwa chinoratidza simba, kugara kwenguva refu uye hunyanzvi hwekugadzira nemazvo. Yakagadzirwa uchishandisa nzira yepamusoro yespiral welding, mapaipi edu anogadzirwa kubva kuma coil esimbi anoputirwa nekupisa akagadzirwa nokungwarira kuita chimiro che cylindrical uye anosungirirwa pamwe chete nemusono wespiral. Iyi nzira itsva yekugadzira haingobatsiri chete chimiro chemapaipi, asiwo inoita kuti agone kumira zvakanyanya.

    Kukambani yedu, tinozvirumbidza nekuzvipira kwedu kusingazununguki mukugutsa vatengi. Mumakore apfuura, takavaka mukurumbira wekubudirira nekuisa pamberi zvinodiwa nevatengi vedu padanho rega rega rekutenga. Kubva pakubvunzana usati watengesa kusvika pakutsigira mukati mekutengesa uye masevhisi akazara ekutengesa mushure mekutengesa, takazvipira kusangana nezvinodiwa nevatengi vedu. Maitiro aya anotarisa vatengi vedu akatiwanira kuvimba nekuvimbika kwevatengi vedu, avo vanogara vachikoshesa mhando yezvigadzirwa zvedu uye kuvimbika kwemasevhisi edu.

    Hunhu hwedu hwepamusoropombi yemusono inotendererayakakodzera kushandiswa kwakasiyana-siyana, kusanganisira kuvaka, mafuta negesi, uye kutakurwa kwemugungwa. Nesimba rayo guru uye kugara kwenguva refu, yakagadzirirwa kutsungirira kumanikidzwa uye kuramba ngura, zvichiita kuti ive mhinduro inogara kwenguva refu yezvinodiwa zvako zvepombi.

    Kubatsira Kwechigadzirwa

    1. Chimwe chezvakanakira zvikuru zvepombi yemusono inotenderera isimba rayo rakanaka. Maitiro ekubatanidza spiral anogonesa kusanganisa nguva dzose, nokudaro zvichiwedzera kunaka kwechimiro chepombi. Izvi zvinoita kuti ive yakanaka kutakura mvura nemagasi pasi pekumanikidzwa kwakanyanya.

    2. Maitiro ekugadzira anoshanda zvakanaka, zvichiita kuti mapaipi marefu agadziriswe pasina chikonzero chekubatanidza, izvo zvinogona kunge zviri zvinhu zvisina kunaka.

    3. Imwe mukana mukuru wepombi yemusono inotendereraimhando yekushandiswa kwayo kwakasiyana-siyana. Inogona kugadzirwa muhukuru hwakasiyana-siyana uye ukobvu hwemadziro kuti ishandiswe mumhando dzakasiyana-siyana kubva pakutakura mafuta negesi kusvika kumasisitimu emvura.

    4. Makambani anogadzira mapaipi aya anonyanya kukoshesa kugutsikana kwevatengi uye anopa mabasa akazara ekutengesa usati watengesa, panguva yekutengesa, uye mushure mekutengesa. Kuzvipira uku kunoita kuti vatengi vagamuchire zvigadzirwa zvakagadzirirwa zvavanoda, zvichiwedzera ruzivo rwavo rwese.

    Kushaikwa kwechigadzirwa

    1. Maitiro ekubatanidza spiral anogona kuoma kupfuura nzira dzechinyakare dzekubatanidza, izvo zvinogona kukonzera mitengo yakakwira yekugadzira.

    2. Kunyange zvazvo mapaipi emusono akasimba, anogona kunge asinganyanyi kubatwa nengura kupfuura mamwe mapaipi uye anoda machira ekudzivirira kana kurapwa.

     

    pombi yesimbi inotenderera

     

     

    Mibvunzo Inowanzo bvunzwa

    Mubvunzo 1: Chii chinonzi spiral seam pipe?

    Pombi yemusono inotenderera inogadzirwa uchishandisa nzira yakasarudzika inonzi spiral welding process. Iyi tekinoroji itsva inosanganisira ma coil esimbi anoputirwa nekupisa anogadzirwa kuita chimiro che cylindrical uye anosungirirwa pamwe chete nemusono unotenderera. Pombi inobuda haina kungova nesimba rakawanda chete asiwo inogara kwenguva refu, zvichiita kuti ive yakakodzera kushandiswa kwakasiyana-siyana, kusanganisira kutakurwa kwemafuta negesi, kuwanikwa kwemvura uye rutsigiro rwechivakwa.

    Q2: Sei uchifanira kusarudza pombi yemusono yemhando yepamusoro?

    Chinhu chikuru chinobatsira pamapombi emusono emhando yepamusoro ndechekugadzirwa kwawo kwakasimba. Maitiro ekubatanidza mapombi anotenderera anobvumira kusungirirwa nguva dzose, izvo zvinowedzera kusimba uye kuramba kumanikidzwa kwepombi. Pamusoro pezvo, mapombi aya anogona kugadzirwa muhukuru hwakasiyana-siyana uye ukobvu kuti agutse zvinodiwa nemapurojekiti akasiyana.

    Mubvunzo 3: Chii chandinofanira kutsvaga mumutengesi?

    Pakusarudza mutengesi we spiral seam tube, zvakakosha kusarudza kambani inonyanya kugutsikana nevatengi. Tsvaga mutengesi anopa mabasa akazara ekutengesa, kutengesa, uye mushure mekutengesa. Kambani ine mukurumbira ichaita shuwa kuti zvigadzirwa zvayo zvinosangana nezvinodiwa zvakatarwa uye inogona kugutsa zvaunoda, ichiva nechokwadi chekuti unogamuchira zvigadzirwa nemasevhisi emhando yepamusoro ayo vatengi vako vachafarira.
