    Kukwesha Pipe Line Spiral Seam Steel Pombi

    Kuwedera Mutsetse wePaipi Mapaipi eSimbi Anotenderera Mufananidzo Wakaratidzwa
    • Kukwesha Pipe Line Spiral Seam Steel Pombi

    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

    KuCangzhou Spiral Steel Pipe Group Co., Ltd., Yedumapaipi emusono anotendererazvigadzirwa zvemhando yepamusoro zvinosangana nezvinodiwa zveindasitiri. Mapaipi edu akagadzirirwa kushandiswa kwakasiyana-siyana uye anozivikanwa nekugara kwenguva refu, kusimba uye kuramba ngura.

    Kabhoni ndiyo chinhu chinonyanya kukosha musimbi uye ndiyo hwaro hwekusiyanisa simbi nesimbi. Mapaipi edu emusono anotenderera akagadzirwa nesimbi yekabhoni yemhando yepamusoro inoita kuti pave nesimba rakawanda uye kugara kwenguva refu. Nehuwandu hwayo hwekabhoni hwakanaka, mapaipi edu akakodzera kushandiswa kwakasiyana-siyana mumaindasitiri.

    Pamusoro pekabhoni, machubhu edu espiral seam ane zvimwe zvinhu zvakakosha zvakaita senickel nechromium. Nickel isimbi ine ferromagnetic inowedzera simba uye kupenya kwepombi. Pamusoro pezvo, inodzivirira ngura uye inoita kuti pombi dzedu dzigare kwenguva refu. Kune rumwe rutivi, chromium chinhu chakakosha musimbi isina ngura uye ine kuramba ngura kwakanaka. Kuiswa kwechromium mumapombi edu espiral seam kunowedzera hupenyu hwavo hwenguva refu uye kuvimbika.

    Chimwe chezvakanakira zvikuru zvemapaipi edu emusono wespiral idhizaini yawo isina musono, iyo inowanikwa kuburikidza netekinoroji yepamusoro yekuwelda. Tekinoroji yedu yemazuva ano yekuwelda yeSAWH (Submerged Arc Spiral Welding) inovimbisa chisungo chakasimba uye chinogara kwenguva refu pakati pemaplate esimbi emapaipi. Tekinoroji iyi yekuwelda haingowedzere hunhu hwemuchina wepaipi chete, asiwo inovimbisa kuti mukati mepombi munogara zvakanaka, izvo zvinoita kuti mvura dzakasiyana-siyana kana magasi zvifambe zvakanaka.

    Mapombi edu emusono anotenderera anoshandiswa zvakanyanya mumaindasitiri akawanda, anosanganisira mafuta negesi, kutakurwa kwemvura, kuvaka nekuvandudza zvivakwa. Anogona kushandiswa mumapurojekiti ekunze nekunze kwegungwa uye mumasisitimu emapombi kune zvinangwa zvakasiyana. Nekudzivirira kwayo ngura uye simba rayo rekudhonza, mapombi edu ndiwo sarudzo yekutanga yekuwedera mapaipi munzvimbo dzakaoma.

    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.

    KuCangzhou Spiral Steel Pipe Group Co., Ltd., tinoisa hunhu uye kugutsikana kwevatengi pakutanga. Chikwata chedu chevashandi vakazvipira chinoona kuti pombi yega yega yemusono inoongororwa zvakanyanya kuti isvike padanho repasi rose. Pamusoro pezvo, tinopa nzira dzakasiyana-siyana dzekuputira pombi, kusanganisira epoxy, polyethylene uye simende, kuti tiwedzere kuramba ngura kwepombi uye kuwedzera hupenyu hwayo hwekushanda.

    Pombi yeSSAW

    Muchidimbu

    Cangzhou Spiral Steel Pipe Group Co., Ltd. inodada nekupa mapaipi emhando yepamusoro espiral seam kune akasiyana siyana mashandisirwo. Tinonyanya kutarisa pakugadzira nemazvo, tekinoroji yepamusoro yekuwelda uye zvinhu zvemhando yepamusoro kuti tipe vatengi mhinduro dzakavimbika uye dzinoshanda kune zvavanoda pakuisa mapaipi. Vimba nesu kuti tizadzise zvese zvaunoda uye tizvionere kuvimbika uye kusimba kwemapaipi edu espiral seam.
