    Kuyambitsa chitoliro chachitsulo cha S235 J0 - njira yosunthika yopangidwa kuti ikwaniritse zosowa zosiyanasiyana zamakampani amakono. Zopangidwa mu fakitale yamakono yomwe ili mumzinda wa Cangzhou, m'chigawo cha Hebei, kampani yathu yakhala ikutsogolera kupanga zitsulo kuyambira 1993. Kampaniyi imakhala ndi malo a 350,000 square meters ndipo ili ndi chuma chonse cha RMB 680 miliyoni. Ndife onyadira kukhala ndi antchito odzipereka a akatswiri aluso 680 odzipereka kupereka zinthu zapamwamba kwambiri.

    Chimodzi mwazinthu zodziwika bwino za S235 J0 spiral zitsulo chitoliro ndi kusinthasintha kwake modabwitsa m'mimba mwake komanso makulidwe a khoma. Kusinthasintha kumeneku kumatithandiza kukwaniritsa zofunikira zosiyanasiyana zopangira, makamaka popanga mapaipi apamwamba kwambiri okhala ndi mipanda. Kaya mukufuna chitoliro chomanga, mafuta ndi gasi, kapena ntchito zina zamafakitale, chitoliro chathu cha S235 J0 chimapangidwa kuti chikwaniritse zolimba.ASTM A139zitsulo chitoliro mfundo kuonetsetsa kudalirika ndi ntchito ngakhale malo wovuta kwambiri.

    Kudzipereka kwathu ku khalidwe labwino ndi luso lamakono kumatanthauza kuti chitoliro chilichonse cha S235 J0 spiral steel pipe chimayesedwa mozama komanso njira zoyendetsera bwino, kuonetsetsa kuti zomwe mumalandira sizimangokwaniritsa komanso kupitirira miyezo yamakampani. Ndi zomwe takumana nazo komanso ukadaulo wathu, tadzipereka kupatsa makasitomala athu mayankho abwino kwambiri ogwirizana ndi zosowa zawo zenizeni.

    Ubwino wa Zamankhwala

    1. Mmodzi mwa ubwino waukulu wa ASTM A139 zitsulo chitoliro ndi kusinthasintha ake awiri ndi makulidwe a khoma specifications. Kusintha kumeneku kumalola opanga kupanga mipope mumitundu yosiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana za polojekiti.

    2. Kuthekera kopanga kwa kampani ngati yathu, yomwe ili ku Cangzhou, m’chigawo cha Hebei, kumawonjezera ubwino wa ASTM A139.

    3. Yakhazikitsidwa mu 1993, fakitale yathu ili ndi malo okwana masikweya mita 350,000, ili ndi chuma chonse cha RMB 680 miliyoni, ndipo imalemba antchito aluso 680. Zomangamanga zazikuluzi zimatithandiza kukwaniritsa zosowa za makasitomala osiyanasiyana pamene tikukhalabe ndi miyezo yapamwamba yopangira.

    Kuperewera kwa katundu

    1. Muyezo wa ASTM A139 sungathe kukwaniritsa zofunikira zonse za mapulogalamu ena, zomwe zimapangitsa kuti ntchito ikhale yochepa kwambiri.

    2. Njira yopangira ikhoza kukhala yovuta komanso yokwera mtengo kusiyana ndi miyezo ina, yomwe ingakhudze mitengo ndi kupezeka.

    FAQ

    Q1: ASTM A139 ndi chiyani?

    ASTM A139 ndi muyezo womwe umafotokoza zofunikira za chitoliro chachitsulo chosakanizidwa ndi magetsi. Mapaipiwa amagwiritsidwa ntchito pochepetsa kupanikizika kwambiri ndipo amadziwika ndi mphamvu zawo komanso kulimba kwawo. Muyezowu umatsimikizira kuti mapaipi amakumana ndi zida zamakina komanso kapangidwe kake, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

    Q2: Ubwino wa S235 J0 wozungulira chitsulo chitoliro ndi chiyani?

    Chimodzi mwazabwino zazikulu za S235 J0 zozungulira zitsulo chitoliro ndi kusinthasintha kwake m'mimba mwake ndi makulidwe a khoma. Kusinthasintha kumeneku kumapangitsa opanga kupanga chitoliro chapamwamba, chokhala ndi mipanda yokhuthala chomwe chimatha kupirira zipsinjo zazikulu ndi zovuta. Kutha kusintha izi kumapangitsa chitoliro cha S235 J0 kukhala chisankho chabwino kwambiri pama projekiti omwe amafunikira kukula ndi mphamvu zenizeni.
