Imibuzo ebuzwa qho:
Q: Yintoni umahluko phakathi kwe-EN 10219 S355JRH kunye ne-EN 10210 S355JRH?
A: I-EN 10219 yenzelwe iindawo ezingenanto ezifakwe kwi-welded (ukuwelda kunye nokwenziwa kwenziwa kubushushu begumbi). I-EN 10210 yenzelwe iindawo ezingenanto ezigqityiweyo ezishushu (ezingenamthungo okanye ezifakwe kwi-welded emva koko zinyangwa ngobushushu). Kwimibhobho ye-LSAW, i-EN 10219 ngumgangatho ofanelekileyo. Iindawo ezigqityiweyo ezishushu ze-EN 10210 zihlala zingenamthungo okanye i-ERW. Zombini zineempawu ezifanayo zoomatshini.
Q: Ngaba ungabonelela nge-S355J2H (impembelelo kwi -20°C) endaweni ye-S355JRH?
A: Ewe. I-S355J2H iyafumaneka xa iceliwe kwiindlela zokusetyenziswa ezisebenzisa ubushushu obuphantsi njengezakhiwo zaselunxwemeni okanye zase-arctic. Ulwakhiwo lweekhemikhali lufana kodwa lunemida eqinileyo kunye nefuthe eliqinisekisiweyo leCharpy kwi -20°C (ubuncinane be-27J). Iindleko ezongezelelweyo ziyasebenza.
Q: Ngaba ninika uphawu lwe-CE kwiipayipi ze-EN 10219?
A: Ewe. I-Womic Steel inesiqinisekiso soLawulo lweMveliso yoMzimba (i-FPC) ngokwe-EN 10219. Sinikezela ngophawu lwe-CE oluneSibhengezo sokuSebenza (i-DoP) kwiipayipi ezithengiswa kwiCandelo lezoQoqosho laseYurophu (i-EEA). Oku kuqinisekisa ukucocwa kwerhafu ngokulula kunye nokwamkelwa kweprojekthi.
Q: Bungakanani ubude obuphezulu bokusebenzisa i-hot-dip galvanizing?
A: Iqabane lethu lokufaka i-galvanizing linobude bebhafu obuyi-13.5m. Ke ngoko, imibhobho efikelela kwi-12.5m inokuntywiliselwa ngokupheleleyo kwaye igqunywe nge-galvanizing. Kwimibhobho emide, singalungiselela i-galvanizing yecandelo okanye sisebenzise enye indlela yokugquma (i-epoxy etyebileyo kwi-zinc). Nceda unxibelelane nathi ngeemfuno ezithile zobude.
Q: Ngaba ungayigaya i-weld flush ukuze intsimbi yesakhiwo eveziweyo ibonakale?
A: Ewe. Kwimibhobho ebonakalayo yesakhiwo (umz., iikholamu kwizikhululo zeenqwelo moya, ii-arches zebhulorho), singayigaya isiciko se-SAW weld ukuze sihlambe kunye nomzimba wepayipi. Lo ngumsebenzi owongezelelweyo kwaye wongeza iindleko kunye nexesha lokuqalisa (malunga ne-+15%). Sicebisa ukuba ucacise le mfuneko ngexesha loku-odola.
Q: Yeyiphi i-coating ecetyiswayo kwintsimbi yesakhiwo yangaphandle?
A: Ukuze kubonakale ngaphandle, i-primer coating (i-epoxy etyebileyo kwi-zinc, i-60-80 microns) iyindlela eqhelekileyo yokukhusela okwethutyana ngexesha lokwakha. Ukuze kukhuselwe ngokusisigxina ngaphandle kokupeyinta, i-hot-dip galvanizing (i-85-100 microns) ingcono kakhulu kwiindawo ezinoburhalarhume. Kwizicelo zangaphakathi, umphezulu ofakwe ioyile okanye i-primer encinci yanele.
Q: Lingakanani ixesha eliqhelekileyo lokuqalisa umbhobho wesakhiwo se-S355JRH LSAW?
A: Ixesha eliqhelekileyo lokufaka izinto: iintsuku ezingama-30-45 kwiisayizi ze-JCOE/UOE. Kwipleyiti eqengqelekayo eludongeni olunzima (> 50mm): iintsuku ezingama-45-60. Kwi-welded kunye ne-ground finish: yongeza iiveki ezi-2. Kwi-hot-dip galvanizing: yongeza iiveki ezi-1-2 kuxhomekeke kwishedyuli yokuhlamba.

● OD 1,016mm (40″) × Ubunzima 30.0mm – 1,200 yeemitha (malunga neetoni ezingama-840) ezenziwe ngepleyiti egoqiweyo enye
Isimbuku:Iimitha ezili-10,700 (10.7 km) zombhobho wolwakhiwo, malunga neetoni ezingama-3,480
Iinkcukacha:Iziphelo ezingenanto zine-chamfer (yokudityaniswa kweempundu), ii-weld caps ezigutyungelweyo ukuya emzimbeni wepayipi (imfuneko yoyilo ebonakalayo), i-primer coating (i-epoxy etyebileyo ye-zinc, ii-microns ezingama-60). Uvavanyo lokuthamba oluyimfuneko, uvavanyo lokugoba olukhokelwayo, i-100% UT yomthungo we-weld kunye ne-10% RT. Impembelelo yeCharpy kwi-0°C (min 27J, ifikelelwe kwi-80-120J). Uphawu lwe-CE oluneSibhengezo sokuSebenza. Uhlolo lweqela lesithathu yi-TÜV Rheinland. Zonke iipayipi zifuna ukuthe tye ≤ 0.15% (kunobunzima kune-0.2%) eqhelekileyo.
Isicelo:I-Al Wakrah Stadium (ekwaziwa ngokuba yi-Al Janoub Stadium), enye yeendawo zeNdebe yeHlabathi yeFIFA ka-2022. Ulwakhiwo lophahla lune-net yentambo exineneyo eneringi yoxinzelelo lwentsimbi kunye nee-radial trusses. Iipayipi ze-LSAW zisetyenziselwe iringi yoxinzelelo oluphambili (1,016mm OD) kunye nee-radial truss chords (813mm, 610mm, 508mm). Uphahla lufikelela malunga ne-200m ububanzi kwaye lugubungela izihlalo ezingama-42,000.
Imingeni yoBugcisa kunye neZisombululo:
● Intsimbi evezwe ngobugcisa - imfuneko yokugaya nge-weld– Ulwakhiwo lophahla lwenkundla lubonakala ngaphakathi nangaphandle. Umthengi wayefuna ukuba ii-weld caps zigutyungelwe emzimbeni wombhobho ukuze zibukeke zigudile. I-Womic yenza ukugaya i-weld kusetyenziswa oomatshini bokugaya abazenzekelayo abajikeleza umhlaba emva koko bagqitywe ngesandla. I-weld nganye ihlolwe ukuba igudile na (uburhabaxa bomphezulu uRa ≤ 6.3μm). Oku kongeze iiveki ezi-2 kwimveliso kodwa kwafikelela kwisiphelo esifunekayo sobuhle.
● Imfuneko yokuthe tye kakhulu– Isangqa soxinzelelo sasifuna imibhobho enobungqindilili ≤ 0.15% (i-EN 10219 esemgangathweni ivumela i-0.2%). I-Womic isebenzise iinkqubo ze-UOE kunye ne-JCOE ngokwandiswa koomatshini ukuze kufezekiswe ubungqindilili obuyi-0.08-0.12%. Umbhobho ngamnye ulinganiswe kwitafile yobungqindilili (ulungelelwaniso lwelaser). Imibhobho enganyamezelaniyo yalungiswa kusetyenziswa i-hydraulic press.
● Ukwambathisa okuphambili kwindawo yasentlango– IQatar inobushushu obuphezulu (ukuya kuthi ga kwi-50°C), ukufuma okuphezulu (ukuya kuthi ga kwi-85% ngexesha lasebusika), kunye nesanti ephefumulayo. I-primer ye-epoxy enobutyebi be-zinc (60 microns) isetyenzisiwe kuzo zonke iipayipi. I-coating iphumelele uvavanyo lokutshiza ngetyuwa (iiyure ezili-1,000, i-ASTM B117) kunye nokuqhekeka okungaphantsi kwe-2mm. Ukufunyanwa kweholide kwi-2kV. Ukuncamathela kulinganiswa kwi-8 MPa (ubuncinci be-5 MPa).
● Izinto ezintsonkothileyo ngexesha lokwakhiwa kweFIFA– Ukwakhiwa kwebala lemidlalo bekuneshedyuli encinci (2020-2021). IWomic yazisa iipayipi ngemithwalo emi-4 (nganye ifikelela kwiitoni ezingama-800-1,000) kwiinyanga ezi-8. Iipayipi zathunyelwa ukusuka eShanghai ukuya eHamad Port (eDoha), emva koko zathunyelwa ngelori ezingama-45km ukuya kwindawo yebala lemidlalo. Ngenxa yemiqathango ye-COVID-19, abahloli beWomic ngokwabo babengenakukwazi ukuhamba. Salungiselela ukuhlolwa okubonwa ngabantu abakude ngevidiyo ebukhoma (i-TÜV kwi-intanethi). Zonke iitoni ezingama-3,480 zamkelwa kude.
● Ukuqina kwempembelelo kubushushu obuphantsi obunokubakho– Nangona iQatar ishushu, ubusuku ebusika bunokwehla bufikelele kwi-10°C, kwaye isakhiwo sophahla sibonakala. EN 10219 S355JRH sifuna iCharpy impact kwi-0°C (27J min). I-Womic ifikelele kwi-80-120J, ngaphezu kwemfuneko. Iingxelo zovavanyo zifakiwe kwiphakheji ye-CE DoP.
●Isiphumo:Ibala lemidlalo i-Al Wakrah lavulwa ngo-2022 laza labamba imidlalo emithandathu yeNdebe yeHlabathi. Isakhiwo sophahla lwentsimbi sidunyiswe kakhulu ngoyilo lwaso oluhle. Umakhi (umyili wentsimbi ophambili waseYurophu) uxele ukuba akukho ziphene zokuwelda ngexesha lokwakhiwa. Zonke iipayipi ze-LSAW zilingana kakuhle kwindawo ngaphandle kokulungiswa kwakhona. I-Womic Steel ifumene ileta yombulelo evela kumakhi oyintloko "ngokuchaneka okugqwesileyo kunye nokugqitywa kokuwelda." Ibala lemidlalo liyaqhubeka nokusebenza njengendawo yemidlalo nemicimbi esetyenziswa ngeendlela ezininzi.
