    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Kwa-Cangzhou Spiral Steel Pipes Group Co., Ltd., siyaziqhenya kakhulu ngokwethula intuthuko yethu yakamuva embonini yamapayipi ensimbi -Ipayipi le-SSAWLo mkhiqizo omusha uhlanganisa ubuchwepheshe obusezingeni eliphezulu nobungcweti obungenakuqhathaniswa ukuze unikeze izixazululo ezingenamthungo zezinhlelo zokusebenza ezahlukahlukene.

    Ipayipi le-SSAW liyiipayipi elihlanganisiwe eliyindilingayenziwe ngamakhoyili ensimbi asezingeni eliphezulu. Sisebenzisa ubuchwepheshe obuthuthukisiwe bokukhipha ukuze siqinisekise izinga lokushisa elihambisanayo kuyo yonke inqubo yokukhiqiza, bese senza ukushisela kwe-arc okufakwe ngokuzenzakalelayo okunezintambo ezimbili ezicijile. Lobu buchwepheshe obucophelelayo buqinisekisa ukubopha okuqinile nokuhlala isikhathi eside, okuholela epayipini eliqinile nelithembekile.

    Enye yezinzuzo ezibaluleke kakhulu ze-ishubhu elihlanganisiwe eliyindilingaamandla ayo aphezulu, adlula lawo epayipi elihlanganisiwe eliqondile. Lokhu kuyenza ifaneleke kakhulu kumaphrojekthi adinga ubuqotho besakhiwo obuthuthukisiwe. Ngaphezu kwalokho, ngenxa yenqubo yayo yokukhiqiza eyingqayizivele, ipayipi elihlanganisiwe elijikelezayo lingakhiqizwa kusetshenziswa ama-billet ensimbi amancane, okuvumela ukukhiqizwa kwamapayipi amakhulu anobubanzi. Ngaphezu kwalokho, ngokusebenzisa izikhala ezinobubanzi obufanayo, singakha kalula amapayipi anobubanzi obuhlukene, sandise ukuguquguquka kwawo.

    Ipayipi le-SSAW

    Ngokuzibophezela okuqinile ekhwalithini, inkampani yethu itshale imali eningi ekumiseni izikhungo zokukhiqiza zesimanje. Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inempahla elinganiselwa ku-680 million yuan. Kodwa okusenza sahluke ngempela yithimba lethu elizinikele. Ithimba lethu labachwepheshe abanamakhono aphezulu abangu-680 yilona elisiqhubela phambili empumelelweni yethu.

    Siyaziqhenya ngomthamo wethu wonyaka wokukhiqiza wamathani angu-400,000 ensimbi ejikelezayo, edlula amazinga omkhakha. Lo mkhiqizo ongenakuqhathaniswa udale inani eliphakeme kakhulu lomkhiqizo elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8. Ithimba lethu elikhuthele liqinisekisa ukuthi yonke idivayisi ephuma esikhungweni sethu ilandela izinyathelo zokulawula ikhwalithi eziqinile, okuqinisekisa amakhasimende ethu ikhwalithi ephezulu.

    Ngamafuphi, amapayipi ahlanganisiwe e-spiral submited arc ashintsha umdlalo embonini yamapayipi ensimbi. Ngamandla awo aphezulu, ukuguquguquka okumangalisayo kanye nokuthembeka okungenakuqhathaniswa, iyisisombululo esiphezulu sazo zonke izidingo zakho zamapayipi ahlanganisiwe. Bambisana ne-Cangzhou Spiral Steel Pipes Group Co., Ltd. namuhla ukuze uzwe ikusasa lemboni yamapayipi ensimbi.
