I-S235 J0 Spiral Steel Pipe - Ukusebenza Okuhle Kakhulu Kwepayipi Elikhulu Elishiselwe Ububanzi
Siyaziqhenya ukwethula umkhiqizo wethu osezingeni eliphezulu,S235 J0 Spiral Steel Pipe, eklanyelwe ukuhlangabezana nezidingo ezikhulayo zezimboni ezihlukahlukene.Njengomkhiqizi ohamba phambili kulo mkhakha, sisebenzisa ubuchwepheshe obuthuthukile nobungcweti ukuze sikhiqize ikhwalithi ephezuluipayipi lomugqa ngokuqina nokusebenza okukhethekile.
Amapayipi ethu ensimbi asontekile enziwa ngamakhoyili ensimbi ngokusebenzisa inqubo yokushisela ye-arc enezintambo ezimbili ezizenzakalelayo enezinhlangothi ezimbili.Ngobuchwepheshe bokubumba obungaguquki bokushisa, siqinisekisa ukuthi ishubhu ngalinye likhiqizwa ngokunemba okuphezulu nokungaguquguquki.Le nqubo yokukhiqiza ecophelelayo iqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zekhwalithi ephezulu, okuyenza ilungele ukusetshenziswa okuhlukahlukene.

Amapayipi ethu ensimbi asontekile enziwa ngamakhoyili ensimbi ngokusebenzisa inqubo yokushisela ye-arc enezintambo ezimbili ezizenzakalelayo enezinhlangothi ezimbili.Ngobuchwepheshe bokubumba obungaguquki bokushisa, siqinisekisa ukuthi ishubhu ngalinye likhiqizwa ngokunemba okuphezulu nokungaguquguquki.Le nqubo yokukhiqiza ecophelelayo iqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zekhwalithi ephezulu, okuyenza ilungele ukusetshenziswa okuhlukahlukene.
Uma kuqhathaniswa namapayipi endabuko ashiselwe,S235 J0 ipayipi lensimbi elivunguzayo inezici ezilandelayo ezibalulekile:
A. Phakathi nenqubo yokubumba, ipuleti lensimbi liyawohloka ngokulinganayo futhi linengcindezi encane eyinsalela.Lokhu akugcini nje ukwandisa impilo yepayipi, futhi kuqinisekisa ukuthi indawo yepayipi ibushelelezi futhi ayinayo imihuzuko noma amaphutha.
b.Inqubo yethu yokushisela i-arc enezinhlangothi ezimbili ethuthukisiwe yenza ukushisela okunembe kube sesimweni esihle kakhulu.Lokhu kunciphisa kakhulu ukwenzeka kokukhubazeka okufana nemiphetho engalungile, ukuchezuka kwe-welding, kanye nokushisela okungaphelele.Ngenxa yalokho, amapayipi ethu anekhwalithi enhle kakhulu yokushisela, kulula ukulawula nokuqinisekisa ukusebenza okuhle kakhulu.
C. Ikhwalithi iyinto eza kuqala kithi.Ngakho-ke, senza ukuhlola kwekhwalithi okuphelele kwe-100% kuwo wonke amapayipi ensimbi esiwakhiqizayo.Lokhu kuhlola okuphelele kuqinisekisa ukuthi amapayipi ethu ahlangabezana nezindinganiso eziphakeme kakhulu zemboni, okukunikeza ukuthula kwengqondo kuyo yonke inqubo yokukhiqiza nokusebenzisa.
Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., siyaziqhenya kakhulu ngokukhiqizaS235 J0 Spiral Steel Pipe.Sitholakala eDolobheni laseCangzhou, eSifundazweni saseHebei futhi besilokhu sisebenzela imboni kusukela ngo-1993. Ihlanganisa indawo engamamitha-skwele angu-350,000 kanye nempahla ephelele ye-yuan eyizigidi ezingu-680, kuye kwabeka isisekelo esiqinile samakhono amahle kakhulu okukhiqiza.Ithimba lethu elizinikele labasebenzi abanamakhono abangu-680 lisebenza ngokuzikhandla ukuze liqinisekise ukukhiqizwa okungenamthungo kanye nokulethwa ngesikhathi kwamathani angu-400,000 amapayipi ensimbi asontekile minyaka yonke.
