    Amapayipi ensimbi e-SSAWenziwe ngamakhoyili ensimbi ama-strip njengezinto zokusetshenziswa, akhishwa ngaphansi kwezinga lokushisa elingashintshi, futhi ashiselwe inqubo yokushisela ye-arc enezintambo ezimbili ezizenzakalelayo enezinhlangothi ezimbili.Lobu buchwepheshe bokukhiqiza obusha buqinisekisa amazinga aphezulu okunemba nokuqina, okwenza amapayipi ethu afaneleke ekufakweni kwemigqa yamanzi angaphansi komhlaba.

    Ipayipi Lomugqa Wamanzi Angaphansi Komhlaba

    Inhliziyo yalokhuipayipi lensimbi elivunguzayoumklamo wayo ozungezayo oyingqayizivele.Insimbi ye-strip ifakwa kudivayisi yepayipi elishiselwe futhi kancane kancane igoqwe ngamarola amaningi ukuze kwakheke ishubhu eliyindilinga elingenalutho elinesikhala esivulekayo.Inamandla okulungisa inani lokunciphisa le-roller extrusion, futhi igebe le-weld lingalawulwa phakathi kuka-1-3mm ukuze kuqinisekiswe uxhumano olungenamthungo noluqinile.Ukwengeza, iziphetho zombili zejoyinti elishiselwe zishibilika kahle, zinikeza isiphetho esihle.

    Amapayipi ensimbi e-SSAW anezici eziningana eziwahlukanisa namapayipi ensimbi endabuko.Isakhiwo sayo esivunguzayo sinamandla amakhulu kakhulu nokumelana namandla angaphandle, okuqinisekisa ukuphepha nokuthembeka kwesistimu yokulethwa kwamanzi.Ngaphezu kwalokho, inqubo yokushisela yekhwalithi ephezulu iqinisekisa ukuthi amalunga awavuzi futhi avimbele ukugeleza kwamanzi noma ukungcola.Ngokwakhiwa kwalo okuqinile nokuxhumana okuvikelekile, lelipayipi liqinisekisa ukusebenza okuhlala isikhathi eside futhi linciphisa izidingo zokunakekelwa, okulenze libe yisixazululo esingabizi kakhulu kunoma iyiphi iphrojekthi yomzila wamanzi angaphansi komhlaba.

    a.Indlela ye-deoxidation ikhethwe kanje:

    FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).

    b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

    Lo mkhiqizo oyingqayizivele uklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zemboni.Ukuthi ukwakhiwa kwamapayipi kamasipala amanzi kanye nezinhlelo zokuthutha indle noma ukuthutha igesi yemvelo namafutha ngokuhamba amabanga amade, amapayipi ashiselwe yi-arc angaphansi kwamanzi ayisinqumo sokuqala.Ukuguquguquka kwayo kudlulela ezinhlelweni zenqwaba yamapayipi, okuhlinzeka ngokuzinza okungenakuqhathaniswa namandla okuthwala umthwalo.Ngamandla abo aphakeme nokuthembeka, amapayipi ethu adlula konke okulindelwe ngokusebenza nokuphila isikhathi eside.

    Kwa-Cangzhou Spiral Steel Pipe Group Co., Ltd., ukuzibophezela kwethu ekwenzeni okuhle akunyakazi.Njengoba sineminyaka eminingi yesipiliyoni nobuchwepheshe bemboni, siyaziqhenya ngokuletha imikhiqizo yekhwalithi ehlangabezana namazinga aphezulu.Izikhungo zethu zokukhiqiza ezisezingeni eliphezulu kanye nezinqubo eziqinile zokulawula ikhwalithi ziqinisekisa ukuthi wonke amapayipi ensimbi ashiselwe yi-spiral arc ashiselwe ephuma efektri asezingeni eliphezulu kakhulu.

    Ipayipi le-SSAW

    Ngamafuphi, ipayipi lensimbi elishiselwe ngaphansi kwe-arc eliguquguqukayo lizoshintsha imboni yamapayipi amanzi angaphansi komhlaba.Ifaka ukwakhiwa okusezingeni eliphezulu, amajoyinti angavuzi namandla aphakeme, leli payipi liyisinqumo esiphezulu kunoma iyiphi iphrojekthi yokudluliswa kwamanzi.Kholwa ukuthi i-Cangzhou Spiral Steel Pipe Group Co., Ltd. ingakunikeza isisombululo esingcono kakhulu sokuhlangabezana nezidingo zakho.Izwa ikusasa lezinhlelo zamapayipi amanzi angaphansi komhlaba ngepayipi lensimbi le-SSAW.
