    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Kwa-Cangzhou Spiral Steel Pipes Group Co., Ltd., siyaziqhenya ukwethula impumelelo yethu yakamuva embonini yamapayipi ensimbi -Ipayipi le-SSAW.Lo mkhiqizo omusha uhlanganisa ubuchwepheshe obusezingeni eliphezulu nobungcweti obungenakuqhathaniswa ukuze unikeze izixazululo ezingenamthungo zezinhlelo zokusebenza ezihlukahlukene.

    Ipayipi le-SSAW liyi-aipayipi elishiselwe okuvunguzaeyenziwe ngamakhoyili ensimbi asezingeni eliphezulu.Sisebenzisa ubuchwepheshe be-extrusion obuthuthukisiwe ukuze siqinisekise izinga lokushisa elingaguquki kuyo yonke inqubo yokukhiqiza, bese senza i-arc welding engaphansi kwe-arc enezintambo ezimbili emaceleni ezenzakalelayo.Lobu buchwepheshe bokucophelela buqinisekisa isibopho esiqinile nesiqinile, okuholela epayipini eliqinile nelithembekile.

    Enye yezinzuzo ezibaluleke kakhulu zeKuvunguza ashiselwe tubeamandla ayo aphakeme, adlula lawo wepayipi elishiselwe ngomthungo oqondile.Lokhu kuyenza ilungele amaphrojekthi adinga ubuqotho besakhiwo obuthuthukisiwe.Ngaphezu kwalokho, ngenxa yenqubo yokukhiqiza eyingqayizivele, ipayipi elihlanganisiwe elivunguzayo lingakhiqizwa kusetshenziswa amabhilidi ensimbi emincane, okuvumela ukukhiqizwa kwamapayipi amakhulu obubanzi.Ukwengeza, ngokusebenzisa izikhala zobubanzi obufanayo, singakwazi ukukhiqiza kalula amashubhu anobubanzi obuhlukahlukene, siqhubeke sandise ukuguquguquka kwawo.

    Ipayipi le-SSAW

    Ngokuzibophezela okuqinile kwekhwalithi, inkampani yethu itshale izinsiza ezibalulekile ekumiseni izindawo zokukhiqiza ezisezingeni eliphezulu.Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inempahla ephelele ye-yuan eyizigidi ezingu-680.Kodwa okusehlukanisa ngempela yiqembu lethu elizinikele.Abasebenzi bethu abangama-680 ochwepheshe abanamakhono aphezulu bangamandla aqhuba impumelelo yethu.

    Siyaziqhenya ngomthamo wethu wokukhiqiza waminyaka yonke wamathani angu-400,000 wamashubhu ensimbi avunguzayo, adlula amazinga embonini.Lokhu okukhiphayo okungenakuqhathaniswa kudale inani eliphezulu kakhulu lokukhiphayo lama-yuan ayizigidi eziyizinkulungwane eziyi-1.8.Ithimba lethu elikhuthele liqinisekisa ukuthi zonke izisetshenziswa eziphuma endaweni yethu zinamathela ezindleleni zokulawula ikhwalithi eziqinile, eziqinisekisa amakhasimende ethu ikhwalithi ephezulu.

    Kafushane, amapayipi ashiselwe i-arc angaphansi kwamanzi ayi-spiral ayinguquko yemboni yamapayipi ensimbi.Ngamandla ayo aphakeme, ukuguquguquka okukhethekile nokuthembeka okungenakuqhathaniswa, iyisixazululo esikhulu sazo zonke izidingo zakho zamapayipi ashiselwe.Sebenzisana ne-Cangzhou Spiral Steel Pipes Group Co., Ltd. namuhla ukuze uthole ikusasa lemboni yamapayipi ensimbi.
