I-SSAW Pipe API Spec 5L (PSL2) yoMbhobho weGesi yeNdalo
ECangzhou Spiral Steel Pipes Group Co., Ltd., sinebhongo kakhulu ngokubonisa impumelelo yethu yamva nje kushishino lwemibhobho yentsimbi -umbhobho we-SSAW.Le mveliso entsha idibanisa iteknoloji yokusika kunye nobuchule obungenakulinganiswa ukubonelela ngezixazululo ezingenamthungo kwiintlobo ezahlukeneyo zezicelo.
Umbhobho we-SSAW yiumbhobho odityanisiweyoyenziwe kwi-coil yentsimbi ekumgangatho ophezulu.Sisebenzisa itekhnoloji ye-extrusion ephezulu yokuqinisekisa ubushushu obungaguqukiyo kuyo yonke inkqubo yemveliso, kwaye emva koko senze i-arc yokuwelda i-arc ezenzekelayo ngamacala amabini.Ubuchwephesha obucokisekileyo buqinisekisa ibhondi eqinile kwaye ehlala ihleli, ekhokelela kumbhobho oqinileyo nothembekileyo.

Enye yeenzuzo ezibalulekileyo zeityhubhu edityanisiweyongamandla ayo angaphezulu, adlula lawo ombhobho odityanisiweyo othe ngqo.Oku kuyenza ilungele iiprojekthi ezifuna imfezeko yolwakhiwo olwandisiweyo.Ukongeza, ngenxa yenkqubo yayo ekhethekileyo yokuvelisa, i-spiral welded pipe inokuveliswa kusetyenziswa iibhilidi zentsimbi ezincinci, ezivumela ukuveliswa kwemibhobho emikhulu yobukhulu.Ukongeza, ngokusebenzisa izikhewu ezinobubanzi obufanayo, sinokwenza ngaphandle komgudu ukwenza iityhubhu ezinobubanzi obahlukeneyo, sandise ngakumbi ukuguquguquka kwayo.
Ngokuzibophelela ngamandla kumgangatho, inkampani yethu ityale izibonelelo ezibalulekileyo ekusekeni amaziko okuvelisa akumgangatho ophezulu.Inkampani ithatha indawo ye-350,000 yeemitha zesikwere kwaye inempahla ye-yuan ezigidi ezingama-680.Kodwa eyona nto isahlulayo liqela lethu elizinikeleyo.Abasebenzi bethu abangama-680 abanezakhono eziphezulu banamandla okuqhuba impumelelo yethu.
Siyazingca ngomthamo wethu wonyaka wemveliso yeetoni ezingama-400,000 zeetyhubhu zentsimbi ezijikelezayo, ezidlula imigangatho yoshishino.Le mveliso ingenakulinganiswa idale ixabiso lemveliso eliphezulu kakhulu le-1.8 yeebhiliyoni zeeyuan.Iqela lethu elikhutheleyo liqinisekisa ukuba zonke izixhobo ezishiya indawo yethu zithobela eyona milinganiselo ingqongqo yolawulo lomgangatho, iqinisekisa abathengi bethu umgangatho ophezulu.
Isishwankathelo, imibhobho ye-arc edityanisiweyo ye-spiral iyinto etshintshayo kushishino lwemibhobho yentsimbi.Ngamandla ayo aphezulu, ukuguquguquka okukhethekileyo kunye nokuthembeka okungenakulinganiswa, sisisombululo esiphezulu kuzo zonke iimfuno zakho zemibhobho edityanisiweyo.Sebenzisana neCangzhou Spiral Steel Pipes Group Co., Ltd. namhlanje ukufumana ikamva loshishino lombhobho wentsimbi.
