    Mwachidule

    "Lamulani muyezo ndi tsatanetsatane, wonetsani mphamvu ndi khalidwe". Bizinesi yathu yayesetsa kukhazikitsa ogwira nawo ntchito agulu ogwira ntchito bwino komanso okhazikika ndikuwunika njira yabwino yoyendetsera ntchito pamtengo wokwanira wa GB5310 20G 20MnG 20MoG High Pressure Seamless Steel Boiler Pipes. Pakali pano, tikhoza kupereka pafupifupi mitundu yonse ya carbon zitsulo ndi Cr-Mo aloyi mipope zitsulo ndi koyenera ndipo anapeza mbiri yabwino ndi magawo akuluakulu pa msika zoweta ndi kunja.
    Mayankho athu amadziwika kwambiri komanso odalirika ndi ogwiritsa ntchito ndipo amatha kukumana ndikusintha kosalekeza kwa zosowa zachuma ndi chikhalidwe. Ndife olandiridwa kwa makasitomala atsopano ndi akale ochokera m'mitundu yonse kuti atilumikizane ndi mabizinesi am'tsogolo ndikupambana!

    Kugwiritsa ntchito

    Amagwiritsidwa ntchito kwambiri popanga zitsulo zapamwamba kwambiri za carbon structural steel, alloy structural chitsulo ndi mapaipi achitsulo osatentha osagwira kutentha osasunthika kuti azitha kuthamanga kwambiri komanso mapaipi otenthetsera pamwamba.

    Amagwiritsidwa ntchito kwambiri pakuthamanga kwambiri komanso kutentha kwambiri kwa boiler (chubu chapamwamba chotenthetsera, chubu chotenthetsera, chubu chowongolera mpweya, chubu chachikulu cha nthunzi yama boiler okwera komanso okwera kwambiri). Pansi pa kutentha kwa mpweya wa flue ndi mpweya wa madzi, chubucho chidzasungunuka ndi kuwononga. Ndikofunikira kuti chitoliro chachitsulo chikhale chokhazikika kwambiri, kukana kwambiri makutidwe ndi okosijeni ndi dzimbiri, komanso kukhazikika kwadongosolo.

    Utali:

    Utali wanthawi zonse wa mipope yachitsulo ndi 4 000 mm ~ 12 000 mm. Pambuyo pokambirana pakati pa wogulitsa ndi wogula, ndikudzaza mgwirizanowu, ukhoza kuperekedwa mapaipi achitsulo ndi kutalika kwa 12 000 mm kapena kufupikitsa kuposa I 000 mm koma osachepera 3 000 mm; kutalika kwapang'onopang'ono Kuchuluka kwa mapaipi achitsulo osakwana 4,000 mm koma osachepera 3,000 mm sikuyenera kupitilira 5% ya kuchuluka kwa mapaipi achitsulo omwe amaperekedwa.

    Kulemera kwake:
    Pamene chitoliro chachitsulo chimaperekedwa molingana ndi m'mimba mwake mwadzina ndi makulidwe a khoma lodziŵika kapena m'mimba mwake mwadzina ndi makulidwe a khoma, chitoliro chachitsulo chimaperekedwa molingana ndi kulemera kwake. Itha kuperekedwanso molingana ndi kulemera kwamalingaliro.
    Pamene chitoliro chachitsulo chimaperekedwa molingana ndi m'mimba mwake mwadzina ndi makulidwe ochepa a khoma, chitoliro chachitsulo chimaperekedwa molingana ndi kulemera kwake; maphwando ogulitsa ndi ofunikira amakambirana. Ndipo zikuwonetsedwa mu mgwirizano. Chitoliro chachitsulo chikhoza kuperekedwanso molingana ndi kulemera kwa chiphunzitso.

    Kulekerera kulemera:
    Malinga ndi zofunikira za wogula, pambuyo pokambirana pakati pa wogulitsa ndi wogula, ndi mu mgwirizano, kupatuka pakati pa kulemera kwake ndi kulemera kwake kwa chitoliro chachitsulo kudzakwaniritsa zofunikira izi:
    a) Chitoliro chachitsulo chimodzi: ± 10%;
    b) Gulu lililonse la mapaipi achitsulo okhala ndi kukula kochepa kwa 10 t: ± 7.5%.

    Chofunikira Choyesa

    Mayeso a Hydraustatic:

    Chitoliro chachitsulo chiyenera kuyesedwa hydraulically mmodzimmodzi. Kuthamanga kwakukulu koyesa ndi 20 MPa. Pansi pa kukakamizidwa kwa mayeso, nthawi yokhazikika iyenera kukhala yosachepera 10 s, ndipo chitoliro chachitsulo sichiyenera kutuluka.

    Wogwiritsa ntchito akavomera, kuyesa kwa hydraulic kumatha kusinthidwa ndi kuyesa kwa eddy panopa kapena kuyesa kwa maginito kutayikira.

    Mayeso Osawononga:

    Mipope yomwe imafuna kuyang'anitsitsa kwambiri iyenera kuyang'aniridwa ndi ultrasonically mmodzimmodzi. Pambuyo pa zokambiranazo zimafuna chilolezo cha chipanicho ndipo zafotokozedwa mu mgwirizano, mayesero ena osawononga akhoza kuwonjezeredwa.

    Mayeso a Flattening:

    Machubu okhala ndi mainchesi akunja opitilira 22 mm adzayesedwa kuphwanyidwa. Palibe delamination yowoneka, mawanga oyera, kapena zonyansa zomwe ziyenera kuchitika panthawi yonse yoyesera.

    Kuyesa kwa Flaring:

    Malinga ndi zofunika za wogula ndi ananena mu mgwirizano, chitoliro zitsulo ndi awiri akunja ≤76mm ndi khoma makulidwe ≤8mm akhoza kuchita flaring mayeso . Kuyesera kunkachitika kutentha kwa chipinda ndi taper ya 60 °. Pambuyo pakuwotcha, kutentha kwapakati pakunja kuyenera kukwaniritsa zofunikira patebulo lotsatirali, ndipo zoyeserera siziyenera kuwonetsa ming'alu kapena ming'alu.
