A: Umlingani wethu we-galvanizing unobude bokugeza obungu-13.5m. Ngakho-ke, amapayipi afinyelela ku-12.5m angacwiliswa ngokuphelele futhi afakwe i-galvaning. Kumapayipi amade, singahlela i-galvanizing yesigaba noma sisebenzise enye indlela yokugqoka (i-epoxy ecebile nge-zinc). Sicela usithinte ukuze uthole izidingo ezithile zobude.

U: Ungakwazi yini ukugaya i-weld flush yensimbi yokwakha eveziwe?
A: Yebo. Kumapayipi abonakalayo (isib. amakholomu asezikhumulweni zezindiza, ama-arches ebhuloho), singagaya isivalo se-SAW weld ukuze sihlanzwe ngomzimba wepayipi. Lokhu kuwumsebenzi owengeziwe futhi wengeza izindleko nesikhathi sokuhola (cishe +15%). Sincoma ukucacisa le mfuneko ngesikhathi soku-oda.

Q: Yikuphi ukumbozwa okunconywayo ngensimbi yesakhiwo yangaphandle?
A: Ukuze kubonakale ngaphandle, i-primer coating (i-epoxy ecebile nge-zinc, ama-micron angu-60-80) iyindinganiso yokuvikela okwesikhashana ngesikhathi sokwakha. Ukuze kuvikelwe unomphela ngaphandle kokupenda, i-hot-dip galvanizing (ama-micron angu-85-100) ingcono kakhulu ezindaweni ezinolaka. Ukuze kusetshenziswe ngaphakathi, indawo enamafutha noma i-primer encane yanele.

Q: Yisiphi isikhathi esijwayelekile sokuhola sepayipi lesakhiwo le-S355JRH LSAW?

Imininingwane:Iziphetho ezingenalutho ezine-chamfer (yokushisela izinqe), izimbobo zokushisela ezifakwe phansi zihlanzwe emzimbeni wepayipi (imfuneko yesakhiwo eveziwe), i-primer coating (i-epoxy ecebile nge-zinc, ama-micron angu-60). Ukuhlolwa kokuthamba okuphoqelekile, ukuhlolwa kokugoba okuqondisiwe, i-UT engu-100% yomthungo wokushisela kanye ne-10% RT. Umthelela we-Charpy ku-0°C (min 27J, kufinyelelwe ku-80-120J). Ukumaka kwe-CE ngeSimemezelo Sokusebenza. Ukuhlolwa komuntu wesithathu yi-TÜV Rheinland. Wonke amapayipi adinga ukunemba ≤ 0.15% (kuqine kune-0.2%) ejwayelekile.

Isicelo:I-Al Wakrah Stadium (eyaziwa nangokuthi i-Al Janoub Stadium), enye yezindawo zeNdebe Yomhlaba ye-FIFA ka-2022. Isakhiwo sophahla sakhiwe ngenetha yekhebula elicindezelwe elinendandatho yokucindezela yensimbi kanye nezinsika ze-radial. Amapayipi e-LSAW asetshenziselwa indandatho yokucindezela eyinhloko (1,016mm OD) kanye nezinsika ze-radial truss (813mm, 610mm, 508mm). Uphahla luhlanganisa cishe ububanzi obungama-200m futhi luhlanganisa izihlalo ezingu-42,000.

Izinselele Zobuchwepheshe Nezixazululo:

● Insimbi eveziwe yezakhiwo - imfuneko yokugaya nge-weld– Isakhiwo sophahla lwenkundla sibonakala ngaphakathi nangaphandle. Iklayenti lalidinga ukuthi izigqoko zokushisela zifakwe emanzini emzimbeni wepayipi ukuze zibukeke zibushelelezi. I-Womic yayisigaya ngokushisela isebenzisa imishini yokugaya ezenzakalelayo elandelwa ukuqeda ngesandla. Ukushisela ngakunye kwahlolwa ukuthi kubushelelezi yini (ubulukhuni bomphezulu Ra ≤ 6.3μm). Lokhu kwenezele amasonto ama-2 ekukhiqizweni kodwa kwafinyelela ukuqeda kobuhle obudingekayo.

● Imfuneko yokunemba okuphezulu– Indandatho yokucindezela yayidinga amapayipi anokuqondile ≤ 0.15% (i-EN 10219 ejwayelekile ivumela u-0.2%). I-Womic isebenzise izinqubo ze-UOE kanye ne-JCOE ngokwandiswa komshini ukuze kufezwe ukuqondile okungu-0.08-0.12%. Ipayipi ngalinye lalinganiswa etafuleni lokuqondile (ukulungiswa kwelaser). Amapayipi angabekezeleli aqondiswa kusetshenziswa umshini wokucindezela we-hydraulic.

● Ukugqoka okuyinhloko kwendawo ehlane– I-Qatar inokushisa okuphezulu (kufika ku-50°C), umswakama ophezulu (kufika ku-85% ebusika), kanye nesihlabathi esisemoyeni. I-primer ye-epoxy ecebile nge-zinc (60 microns) yafakwa kuwo wonke amapayipi. Isembozo sidlule ekuhlolweni kokufuthwa ngosawoti (amahora ayi-1,000, i-ASTM B117) ngokukhukhuleka okungaphansi kuka-2mm. Ukutholwa kweholide ku-2kV. Ukunamathela kukalwe ku-8 MPa (ubuncane be-5 MPa).

● Izinto eziyinkimbinkimbi ngesikhathi sefasitela lokwakhiwa kwe-FIFA– Ukwakhiwa kwenkundla kwakunesimiso esiqinile (2020-2021). I-Womic ilethe amapayipi ngokuthunyelwa okungu-4 (ngalinye lalingamathani angu-800-1,000) ezinyangeni ezingu-8. Amapayipi athunyelwa esuka eShanghai aya eHamad Port (eDoha), athunyelwa ngamaloli amakhilomitha angu-45 aya endaweni yenkundla. Ngenxa yemikhawulo ye-COVID-19, abahloli be-Womic ngokwabo babengenakukwazi ukuhamba. Sahlela ukuhlolwa kofakazi abakude ngevidiyo ebukhoma (i-TÜV online). Wonke amathani angu-3,480 amukelwa kude.

● Ukuqina komthelela ekushiseni okuphansi okungenzeka kube khona– Nakuba iQatar ishisa, ubusuku ebusika bungehla bufike ku-10°C, futhi isakhiwo sophahla sibonakala. EN 10219 S355JRH sidinga umthelela weCharpy ku-0°C (27J min). I-Womic ifinyelele ku-80-120J, ngaphezu kakhulu kwesidingo. Imibiko yokuhlolwa ifakiwe kuphakheji ye-CE DoP.

●Umphumela:Inkundla yezemidlalo i-Al Wakrah yavulwa ngo-2022 futhi yabamba imidlalo eyisithupha yeNdebe Yomhlaba. Isakhiwo sophahla lwensimbi sidunyiswe kakhulu ngomklamo waso omuhle. Umakhi (umkhi wensimbi ohamba phambili waseYurophu) ubike ukuthi akukho zinkinga zokushisela ngesikhathi sokumiswa. Wonke amapayipi e-LSAW alingana kahle endaweni ngaphandle kokulungiswa kabusha. I-Womic Steel ithole incwadi yokubonga evela kumakhi oyinhloko "ngokunemba okuhle kakhulu kanye nokuqeda ukushisela." Inkundla iyaqhubeka nokusebenza njengendawo yezemidlalo nemicimbi esetshenziswa ngezindlela eziningi.
