    SSAW Steel Pipe Yemvura Yepasi Pevhu

    Pombi yeSimbi yeSSAW Yemugero weMvura wePasi pevhu Mufananidzo Wakaratidzwa
    • SSAW Steel Pipe Yemvura Yepasi Pevhu

    Tsananguro pfupi:

    Tinokugamuchirai kusumo yechigadzirwa chepombi yemusono inotenderera inounzwa kwamuri neCangzhou Spiral Steel Pipe Group Co., Ltd., kambani inotungamira mukugadzira mapaipi esimbi anotenderera uye zvigadzirwa zvekuputira mapaipi muChina.


    Ruzivo rweChigadzirwa

    Matagi eChigadzirwa

    Kuburitswa kwesimbi yakasungirirwa yesimbi inotenderera yakanyudzwa mudengapombi dzemigero yemvura yepasi pevhu

    Cangzhou Spiral Steel Pipe Group Co., Ltd. yatanga pombi yayo itsva yesimbi ine musono, pombi yesimbi ine musono ichachinja indasitiri yemapaipi emvura yepasi pevhu. Pombi iyi inochinja zvinhu mumusika wekutakura mvura netsvina yemumaguta nekuda kwehunhu hwayo hwepamusoro uye mashandiro ayo epamusoro.

    Mapaipi esimbi eSSAWYakagadzirwa nesimbi dzakarukwa sezvinhu zvekugadzira, dzinoburitswa pakupisa kwakafanana, uye dzinosungirirwa neautomatic double-waya double-sided submited arc welding process. Iyi tekinoroji yekugadzira itsva inoita kuti pave nekunyatsojeka uye kugara kwenguva refu, zvichiita kuti mapaipi edu ave akakodzera kushandiswa kwemvura yepasi pevhu.

    Pombi Yemugero Wemvura Wepasi Pevhu

    Moyo weizvipombi yesimbi inotendererandiyo dhizaini yayo yakasiyana yekutenderera. Simbi iyi inoiswa mumudziyo wepombi yakasungirirwa uye inopetwa zvishoma nezvishoma nemaroller akawanda kuti igadzire chubhu yakatenderera isina chinhu ine mukaha wekuvhura. Inokwanisa kugadzirisa huwandu hwekudzikisa hweroller yekuburitsa, uye mukaha wekuchinjisa unogona kudzorwa pakati pe1-3mm kuti ive nechokwadi chekubatana kwakasimba uye kusina mukaha. Pamusoro pezvo, magumo ese ejointi yakasungirirwa anopenya zvakakwana, zvichipa kupedzisa kwakakwana.

    Mapaipi esimbi eSSAW ane hunhu hwakati wandei hunoasiyanisa nemapaipi esimbi echinyakare. Chimiro chayo chedenderedzwa chine simba rakanaka uye chinodzivisa simba rekunze, zvichiita kuti sisitimu yekuendesa mvura ive yakachengeteka uye yakavimbika. Pamusoro pezvo, nzira yekushongedza yemhando yepamusoro inoita kuti majoini asadonhe uye anodzivirira mvura kubuda kana kusvibiswa. Nekuvakwa kwayo kwakasimba uye kubatana kwakasimba, pombi iyi inoita kuti ishande kwenguva refu uye inoderedza zvinodiwa pakugadzirisa, zvichiita kuti ive mhinduro inodhura kune chero chirongwa chemvura yepasi pevhu.

    a. Nzira yekubvisa oxidation inotsanangurwa seinotevera:

    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.

    Chigadzirwa ichi chinoshamisa chakagadzirirwa kusangana nezvinodiwa zvakasiyana-siyana zveindasitiri. Ingave kuvaka masisitimu emvura emaguta uye ekufambisa tsvina kana kutakura gasi rechisikigo nemafuta munzvimbo refu, mapaipi akasungirirwa arc welded anotenderera ndiwo sarudzo yekutanga. Kugona kwawo kunosvika kumasisitimu emapombi, zvichipa kugadzikana kusingaenzaniswi uye kugona kutakura mutoro. Nesimba rawo rakakura uye kuvimbika, mapaipi edu anopfuura zvese zvinotarisirwa maererano nekushanda uye kugara kwenguva refu.

    KuCangzhou Spiral Steel Pipe Group Co., Ltd., kuzvipira kwedu kune hunhu hwakanaka hakuchinji. Neruzivo rwemakore akawanda muindasitiri, tinodada nekupa zvigadzirwa zvemhando yepamusoro zvinosangana nezvinodiwa zvepamusoro. Zvivako zvedu zvekugadzira zvemazuva ano uye maitiro ekudzora mhando akasimba zvinoita kuti pombi yega yega yesimbi inoputirwa nesimbi inobuda mufekitori ive yemhando yepamusoro.

    Pombi yeSSAW

    Muchidimbu, pombi yesimbi yakasungirirwa inotenderera inodzika pasi pevhu ichachinja indasitiri yemapaipi emvura ari pasi pevhu. Iine kuvakwa kwepamusoro-soro, majoini asingadonhe uye simba guru, pombi iyi ndiyo sarudzo yakanakisisa kune chero chirongwa chekutumira mvura. Tenda kuti Cangzhou Spiral Steel Pipe Group Co., Ltd. inogona kukupa mhinduro yakanakisa yekusangana nezvaunoda. Nakidzwa neramangwana remasisitimu emapaipi emvura yepasi pevhu uchishandisa mapaipi esimbi eSSAW.
