I-A252 yeBanga lesi-2 Lepayipi Lepayipi Lensimbi Yezisekelo Embonini Yasogwini
Ezweni elihlala livela lokuthuthukiswa kwengqalasizinda, isidingo sezinto ezithembekile nezihlala isikhathi eside sibalulekile. Siyaziqhenya ngokunikela ngezinqwaba zethu ze-premium, eziklanyelwe ukuhlangabezana nezindinganiso eziqinile ezidingekayo kumapayipi egesi angaphansi komhlaba. Izinqwaba zethu zenziwa ngokunemba, okuqinisekisa ukuthi inqwaba ngayinye ikalwa ngayo ukuze kuqinisekiswe ukuthotshelwa kwemininingwane yemboni.
Izinqwaba zamapayipi ethu zenziwe ngensimbi ye-A252 GRADE 2, into eyaziwa ngamandla ayo nokuqina. Leli banga lensimbi lifaneleka ngokukhethekile izinhlelo zokusebenza ezifaka ukufakwa ngaphansi komhlaba lapho ubuqotho besakhiwo bezinto ezibonakalayo bubalulekile. Ipayipi lensimbi i-A252 GRADE 2 yakhelwe ukumelana nezimo ezinzima ngokuvamile okuhlangatshezwana nazo ezindaweni ezingaphansi komhlaba, okulenza libe inketho ekahle ekufakweni kwepayipi legesi.
Njengesitoko esithenjwayo sepayipi le-SSAW (Spiral Submerged Arc Welded), siqinisekisa ukuthi imikhiqizo yethu ihlangabezana namazinga aphezulu kakhulu. Inqwaba yepayipi ngayinye ikhiqizwa kusetshenziswa amasu okushisela athuthukile akhulisa amandla nokuqina kwempahla. Ipayipi lethu le-SSAW liyaziwa ngezakhiwo zalo ezinhle kakhulu zemishini futhi lilungele ukusetshenziswa okuhlukahlukene, kufaka phakathi amapayipi egesi yemvelo angaphansi komhlaba. Inqubo ye-welding ye-spiral ayihlinzeki nje kuphela isakhiwo esiqinile, kodwa futhi ivumela ubude obude ukuba bukhiqizwe, ukunciphisa isidingo samalunga kanye nokuthuthukisa ubuqotho okuphelele kokufakwa.

Ukuhlaziywa komkhiqizo
Insimbi akufanele ibe ngaphezu kuka-0.050% we-phosphorus.
Ukwehluka Okuvumelekile Kwesisindo Nobukhulu
Ubude benqwaba yamapayipi ngayinye buzokalwa ngokuhlukana futhi isisindo sawo angeke sihluke ngaphezu kuka-15% ngaphezulu noma u-5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle
Ukujiya kodonga kunoma iyiphi indawo akumele kube ngaphezu kuka-12.5% ngaphansi kogqinsi olushiwo
Ubude
Ubude obungahleliwe obubodwa: 16 kuya ku-25ft(4.88 kuya ku-7.62m)
Ubude obuphindwe kabili obungahleliwe: ngaphezulu kwama-25ft kuya ku-35ft(7.62 kuya ku-10.67m)
Ubude obufanayo: ukuhluka okuvumelekile ±1in
Iyaphela
Izinqwaba zamapayipi zizonikezwa iziphetho ezicacile, futhi ama-burrs ekugcineni azosuswa.
Lapho ukuphela kwepayipi okushiwo ukuthi kube yi-bevel iphela, i-engeli izoba ngu-30 kuya ku-35 degree
Ukumaka umkhiqizo
Ubude benqwaba yepayipi ngalinye buzomakwa ngokusemthethweni ngokufakwa isitensela, ukugxivizwa, noma ukugingqika ukuze kuboniswe: igama noma uhlobo lomkhiqizi, inombolo yokushisa, inqubo yomkhiqizi, uhlobo lomthungo we-helical, ububanzi obungaphandle, ukujiya kodonga okulinganiselwe, ubude, nesisindo ngobude beyunithi ngayinye, ukuqokwa okucacisiwe kanye nebanga.
Isici esiyinhloko sezinqwaba zethu ukungaguquguquki kwesisindo. Inqwaba ngayinye ikalwa ngokucophelela futhi sinamathela ekubekezeleni okuqinile ukuze siqinisekise ukuthi isisindo asihlukani ngaphezu kuka-15% noma 5% wesisindo sethiyori. Lokhu kunemba kubalulekile konjiniyela nosonkontileka abathembele ekucacisweni okunembile kwamaphrojekthi abo. Ngokugcina lezi zilinganiso zesisindo, sisiza ukuqinisekisa ukuthi inqubo yokufaka ihamba kahle nokuthi ukusebenza kwesakhiwo kwezinqwaba kuhlangabezana nezindinganiso ezilindelekile.
Ukuzibophezela kwethu kwikhwalithi kudlulela ngale kwenqubo yokukhiqiza. Siyaqonda ukuthi impumelelo yanoma iyiphi iphrojekthi ehilela amapayipi egesi angaphansi komhlaba incike ekuthembekeni kwezinto ezisetshenziswayo. Ngakho-ke, senza amasheke okulawula ikhwalithi aqinile kuzo zonke izigaba zokukhiqiza. Ithimba lethu lochwepheshe lizinikele ekuqinisekiseni ukuthi yonke inqwaba ihlangabezana nezimfuneko ezidingekayo futhi isetshenziswa ngokushesha lapho ilethwa.
Ngaphezu kwezinqwaba zekhwalithi ephezulu, siphinde sinikeze isevisi yamakhasimende enhle kakhulu nokusekelwa. Ithimba lethu elinolwazi lihlala likhona ukuze liphendule noma yimiphi imibuzo ongase ube nayo, linikeze isiqondiso sobuchwepheshe, futhi likusize ukhethe imikhiqizo efanele izidingo zakho ezithile. Siyaziqhenya ngokwakha ubudlelwano besikhathi eside namakhasimende ethu, siqinisekisa ukuthi abatholi kuphela umkhiqizo osezingeni lokuqala, kodwa futhi nokusekelwa abakudingayo ukuze baqedele ngempumelelo iphrojekthi yabo.
Kafushane, izinqwaba zamapayipi ethu e-premium ezenziwe ngensimbi ye-A252 GRADE 2, etholakala ngesevisi yethu yomthengisi wamapayipi we-SSAW, ziyisixazululo esiphelele sephrojekthi yakho yepayipi legesi engaphansi komhlaba. Ngokuzibophezela kwethu kwikhwalithi, ukunemba, kanye nokwaneliseka kwamakhasimende, ungasethemba ukuthi sizokunikeza ngezinto ozidingayo ukuze uqiniseke ukuthi ukuthuthukiswa kwengqalasizinda yakho kuyaphumelela futhi kuphephile. Khetha izinqwaba zamapayipi ethu ukuze uthole isisombululo esinokwethenjelwa, esiqinile, nesisebenzayo sezidingo zakho zokwakha ngaphansi komhlaba.
