    Spiral yakakundwa Arc Welding mumafuta pipe mutsara wekuvaka: Kuverengera hupenyu hwebasa uye kuvimbika

    Spiral yakakundwa Arc Welding mumafuta pombi mutsara wekuvaka: Kuverengera hupenyu hwebasa uye kuvimbika kunoonekwa mufananidzo
    • Spiral yakakundwa Arc Welding mumafuta pipe mutsara wekuvaka: Kuverengera hupenyu hwebasa uye kuvimbika

    Tsananguro pfupi:

    Kuvakwa kweemafuta pipe mitsara Icho chiitiko chakakosha uye chakaoma izvo izvo zvinoda huwandu hwepamusoro hwe tekinoroji yeWalking. Pakati penzira dzakasiyana-siyana nzira dzinoshandiswa, dzakasarudzika Mune ino blog, isu tichasundira mukukosha kweHsaw muhombofu pombi uye tiongorore zvakanakira uye kukosha kukuru mukusangana nenyika's inokura yemafuta ekufambisa zvinodiwa.

    Iko kukosha kweHSAW mumafuta pombi kuvakwa:

    1. Simba uye Kusimba: Imwe yehunhu hwekutanga hweHSAw ndiko kugona kwayo kuumba yakasimba, yakakwirira-ine simba majoini. Iyo inoenderera ichichinjika tekinoroji iyi inokwidziridzwa kutendeka kwechimiro uye kwakashamisika kutadzira zvakakwirira zvekumanikidza, kupisa kwakanyanya uye zvinhu zvakatipoteredza izvoOree pombi mitsaratarisana panguva yehupenyu hwavo hwebasa.

    2. Hupenyu Hurefu uye Kuvimba Kwakasimba: LIOL PIPE Lines inotarisirwa kushanda zvisina musoro kwemakumi emakore, kutakura mafuta pasina kudzikisira kana kutadza. HSAW anoita basa rakakosha mukuzadzisa hupenyu hwakareba hwekushambadzira kwekupisa, kuderedza kushushikana kwekushambadzira, uye kudzivirira kutanga kwekutangisa nekupararira kwese kwekuvimbika kwepombi.

    3. Kushanda kwakasimba: HSAW inokwanisa kuenderera mberi nekuenderera mberi zvikamu zvePombi, saka zvine hunyanzvi hwakakosha mukuvaka pombi. Iyi nzira inoderedza nguva yekuteerera, inowedzera kubereka, inoderedza mari yekuvaka, uye inokodzera kusvika pakupedzisa nguva yepurojekiti.

    4 Mafuta emapiripi akavaka uchishandisa iyi nzira isingasviki yekukora kana kukundikana, kuvandudza kuchengeteka uye kuwedzera kushanda kwekushanda.

    5. Zvakanakira Zvemamiriro ekunze: HSAW anovimbisa kugadzirwa kwekunyatso trems neakakwirira zvakazara kurongeka. Izvi zvinoderedza mukana wePombi Corrosion uye inotevera mafuta kubhururuka, ichidzivirira zvakatipoteredza kubva kunjodzi dzinogona kuenderana nenjodzi dzakabatana nekutadza kwepombi.

    a. Iyo Deoxidation nzira inosarudzwa seinotevera:

    FF: Simbi yakaurayiwa zvizere ine nitrogen inosunga zvinhu mune huwandu hwakaringana kusunga inowanikwa nitrogen inowanikwa (semuenzaniso min. 0,020% yakazara al kana 0,015% solux al).

    b. Iko kukosha kwakanyanya kwe nitrogen hakuratidze kana mimwe yemakemikari ichiratidza mashoma ehuwandu hwehuwandu hwe0,020% neine shoma al / n chiyero che2: 1, kana zvakakwanira zvimwe zvisungo zve-n-zvinosunga zviripo. Iyo n-inosunga zvinhu ichanyorwa mugwaro rekuongorora.

    Mukupedzisa:

    Kuvakwa kwemafuta emapipi kunoda iyo yepamusoro-soro nzira yekuve nechokwadi, kuvimbika uye kuchengeteka. Spiral yakakundwa Arc Welding (HSAW) ndiyo technology yesarudzo yesarudzo iri mumunda uyu nekuda kwekugona kwayo kuumba yakasimba, yakasimba uye yakaremara maWelds. Nezvakanakira zvakawanda zvinosanganisira kuvimbika kutendeka, kuvaka kwakashanda, zvakadzama zvinobatsira uye zvakatipoteredza zvakanaka, HSAw zvinokonzeresa mukusangana nemafuta epasi rose zvidiki zvekufambisa. Sezvo indasitiri yemafuta ichiramba ichiwedzera, kushandiswa kweakarongeka matekinoroji akadai saHsaw kwakakosha kuchengetedza kutendeka uye kuvimbika kwemifuta yemafuta pasi rese.
