    Mapaipi Ozungulira a Chitoliro Chowotcherera Mapaipi Achitsulo

    Kuwotcherera Mzere wa Mapaipi Mapaipi achitsulo a Spiral Seam Chithunzi Chowonetsedwa
    • Mapaipi Ozungulira a Chitoliro Chowotcherera Mapaipi Achitsulo

    Kufotokozera Kwachidule:

    Takulandirani ku chiyambi cha malonda a chitoliro cha msoko chozungulira chomwe chabweretsedwa kwa inu ndi Cangzhou Spiral Steel Pipe Group Co., Ltd., kampani yopanga mapaipi achitsulo chozungulira ndi zinthu zokutira mapaipi ku China.

    Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., Yathumapaipi ozungulira a msokondi zinthu zapamwamba kwambiri zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Mapaipi athu adapangidwira ntchito zosiyanasiyana ndipo amadziwika chifukwa cha kulimba kwawo, mphamvu zawo komanso kukana dzimbiri.

    Mpweya wa kaboni ndiye chinthu chofunikira kwambiri pa chitsulo ndipo ndi maziko osiyanitsa chitsulo ndi chitsulo. Mapaipi athu ozungulira ozungulira amapangidwa ndi chitsulo cha kaboni chapamwamba kwambiri chomwe chimaonetsetsa kuti chili ndi mphamvu komanso kulimba. Chifukwa cha kuchuluka kwa kaboni komwe ali nako, mapaipi athu ndi oyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

    Kuwonjezera pa kaboni, machubu athu ozungulira ali ndi zinthu zina zofunika monga nickel ndi chromium. Nickel ndi chitsulo cha ferromagnetic chomwe chimawonjezera mphamvu ndi kunyezimira kwa chitoliro chonse. Kuphatikiza apo, chimalimbana ndi dzimbiri ndipo chimatsimikizira kuti mapaipi athu amakhala ndi moyo wautali. Komabe, Chromium ndi chinthu chofunikira kwambiri mu chitsulo chosapanga dzimbiri ndipo chimakhala ndi kukana kwabwino kwa dzimbiri. Kuphatikizidwa kwa chromium m'mapaipi athu ozungulira kumawonjezera moyo wawo wautali komanso kudalirika.

    Chimodzi mwa zabwino zazikulu za mapaipi athu ozungulira ndi kapangidwe kawo kopanda msoko, komwe kumachitika kudzera muukadaulo wapamwamba wowotcherera. Ukadaulo wathu wapamwamba kwambiri wowotcherera wa SAWH (Submerged Arc Spiral Welding) umatsimikizira mgwirizano wolimba komanso wokhalitsa pakati pa mbale zachitsulo za mapaipi. Ukadaulo uwu wowotcherera sumangowonjezera mphamvu zamakina a paipi, komanso umawonetsetsa kuti mkati mwake mukhale wosalala, zomwe zimathandiza kuti madzi kapena mpweya wosiyanasiyana uyende bwino.

    Mapaipi athu ozungulira amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kuphatikizapo mafuta ndi gasi, mayendedwe amadzi, zomangamanga ndi chitukuko cha zomangamanga. Itha kugwiritsidwa ntchito m'mapulojekiti am'mphepete mwa nyanja ndi m'mapulogalamu apaipi pazifukwa zosiyanasiyana. Chifukwa cha kukana dzimbiri komanso mphamvu zake zokoka, mapaipi athu ndi chisankho choyamba chowotcherera mapaipi m'malo ovuta.

    a. Njira yochotsera poizoni m'thupi imatchulidwa motere:

    FF: Chitsulo chophwanyika bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka).

    b. Mtengo wapamwamba kwambiri wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al komwe kuli 0,020% ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati pali zinthu zina zokwanira zomangira N. Zinthu zomangira N ziyenera kulembedwa mu Chikalata Chowunikira.

    Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., timaika patsogolo ubwino ndi kukhutitsidwa kwa makasitomala. Gulu lathu lodzipereka la akatswiri limaonetsetsa kuti chitoliro chilichonse chozungulira chikutsatira njira zowongolera bwino khalidwe kuti chikwaniritse miyezo yapadziko lonse lapansi. Kuphatikiza apo, timapereka mitundu yosiyanasiyana ya zokutira mapaipi, kuphatikizapo epoxy, polyethylene ndi simenti, kuti chitolirocho chikhale cholimba komanso cholimba komanso kuti chikhale ndi moyo wautali.

    Cangzhou Spiral Steel Pipe Group Co., Ltd. imadzitamandira popereka mapaipi apamwamba kwambiri ozungulira omwe amagwiritsidwa ntchito m'njira zosiyanasiyana. Timayang'ana kwambiri pakupanga zinthu molondola, ukadaulo wapamwamba wowotcherera ndi zipangizo zabwino kuti tipatse makasitomala mayankho odalirika komanso ogwira mtima pazosowa zawo za mapaipi. Tikhulupirireni kuti tikwaniritse zosowa zanu zonse ndikuwona nokha kudalirika ndi kulimba kwa mapaipi athu ozungulira.
