Inkcazo emfutshane:

I-Womic Steel inika umbhobho wentsimbi we-ASTM A252 weBanga lesi-2 we-LSAW osemgangathweni ophezulu wokufaka iipali zesiseko, ii-piers zebhulorho, iziseko zesakhiwo, kunye nezakhiwo zaselwandle. IBanga lesi-2 linika amandla okuvelisa ubuncinci be-240 MPa (35,000 psi) kunye namandla okunciphisa ubuncinci be-415 MPa (60,200 psi), nto leyo eyenza ukuba ibe lolona didi lokufaka iipali oluchazwe kakhulu kwizicelo zesiseko ngokubanzi. Inkqubo ye-LSAW ibandakanya iindlela ze-JCOE, UOE, kunye ne-rolled plate welding, ezibonelela ngomthungo othe tye we-longitudinal kunye nozinzo oluhle kakhulu. Kwi-diameter enkulu okanye ii-dual pailing ezinzima (ukuya kuthi ga kwi-80mm ubukhulu bodonga), i-Womic isebenzisa i-plate rolling kunye ne-multi-pass submerged arc welding. Ububanzi bangaphandle ukusuka kwi-219mm ukuya kwi-3,000mm (8″ – 120″), ubukhulu bodonga ukusuka kwi-6.0mm ukuya kwi-80mm, ubude ukuya kuthi ga kwi-60m. Isatifikethi sokugaywa, uvavanyo lwe-ultrasonic oluyi-100% (umthungo we-weld), iziphelo ezibengezelayo okanye ezicacileyo, kunye nokwaleka okuchasene nokugqwala (i-coal tar epoxy, i-bitumen, i-zinc) ziyafumaneka. Zifanelekile kwiziseko zebhulorho, ukufakwa kwee-port, ukwakha iziseko ezinzulu, ii-cofferdams, iindonga zokugcina izinto, kunye nokufakwa kwee-highway.

Ubungakanani boMbhobho weNtsimbi ye-LSAW:Ububanzi obungaphandle: 219mm – 3,000mm (8″ – 120″), Ubukhulu bodonga: 6.0mm – 80mm (JCOE/UOE max 50.8mm, ipleyiti eqengqelweyo max 80mm), Ubude: 6m – 18m esemgangathweni, ubude obulungiselelweyo bufikelela kwi-60m

Umbhobho weNtsimbi weLSAW oMgangatho oMgangatho kunye noBanga:I-ASTM A252 Ibanga lesi-2; ikwafumaneka neBanga loku-1 nele-3; i-EN 10248 S235GP, S275GP, S355GP xa iceliwe

Ukusetyenziswa kwePipe yeNtsimbi ye-LSAW:Iinqwaba zesiseko sebhulorho, iinqwaba zezibuko kunye neenqanawa, ukwakha iziseko ezinzulu, ii-cofferdams, iinqwaba zodonga ezigcinayo, iziseko zeempawu zendlela enkulu, iingcango zebhulorho kaloliwe, iinqwaba zokwakha zexeshana, iinqwaba zefender zaselwandle, ukuzinzisa umhlaba

I-Womic Steel inikezela ngamaxabiso asemgangathweni aphezulu nanokukhuphisanayo e-ASTM A252 Grade 2 LSAW steel pipe, ii-steel piles piles, i-JCOE piling pipe, i-heavy wall structural pipe, i-long length piling pipe. Isatifikethi se-mill, uvavanyo lwe-hydro (onganyanzelekanga), ukuhlolwa kwe-UT weld, iziphelo ezibekiweyo/ezicacileyo, i-anti-corrosion coating iyafumaneka. Ubonelelo oluthe ngqo kwifektri yobunjineli bokwakha kunye neeprojekthi zaselwandle kwihlabathi liphela.

Imibuzo ebuzwa qho:

Q: Yintoni umahluko phakathi kwe-ASTM A252 Grade 2 kunye neGrade 3 yokuqokelela izinto?
A: Ibanga lesi-3 linamandla aphezulu (isivuno se-345 MPa xa kuthelekiswa ne-240 MPa) kwaye lisetyenziselwa iziseko ezinzulu okanye iimfuno zomthwalo ophezulu. Ibanga lesi-2 lingabizi kakhulu kwaye lanele ukusetyenziswa kweziseko ngokubanzi (iibhulorho, izakhiwo, amazibuko). Khetha iBanga lesi-2 kwimithwalo eqhelekileyo, iBanga lesi-3 kwimithwalo enzima okanye ukuqhuba ngokunzulu.

Q: Ngaba nibonelela ngemibhobho ye-A252 Grade 2 ene-galvanized coating?
A: Ewe. Sinikezela nge-hot-dip galvanizing ngokwe-ASTM A123. Ubude obuphezulu bokufaka i-galvaning yi-12.5m. Kwiinqwaba ezinde, sicebisa ukuba ufake i-epoxy coating okanye i-bituminous coating.

Q: Bungakanani ubude obuphezulu onokubuvelisa kumbhobho wokufaka iipayipi zeBanga lesi-2?
A: Ubude obuphezulu becandelo elinye yi-18m (JCOE) okanye i-24m (UOE). Kubude obufikelela kwi-60m, sidibanisa amacandelo amaninzi ukusuka ekuqaleni ukuya ekupheleni nge-SAW circumferential welds (100% UT ihlolwe). Oku kuqhelekile kwiimonopile zomoya olwandle.

Q: Ngaba i-ASTM A252 ifuna uvavanyo lwe-hydrostatic?
A: Hayi. I-ASTM A252 ayifuni uvavanyo lwe-hydrostatic kuba imibhobho yokufaka iipayipi ayithinteli uxinzelelo. Nangona kunjalo, ukuba iprojekthi yakho ifuna uvavanyo lwe-hydrotest (umz., ukufakelwa iipayipi ezidibeneyo kunye nokuthuthwa kolwelo), singayenza ngeendleko ezongezelelweyo.

Q: Yeyiphi i-coating ecetyiswayo xa kufakwe i-sea mounts emanzini anetyuwa?
A: Xa kuntywiliselwa emanzini olwandle, kucetyiswa i-coal tar epoxy (600-800 microns) okanye i-glass flake epoxy. Kwiindawo ezitshizayo, sicebisa i-FBE okanye i-epoxy coatings etyebileyo. Kwiindawo zamanzi acocekileyo okanye umhlaba, umbhobho omnyama ocacileyo okanye umphezulu onamafutha uhlala wanele.

Q: Uqinisekisa njani ukuba ii-welds ziyasinda xa ziqhutywa ngesando?
A: Senza uvavanyo lokuthamba (oluyimfuneko) kunye novavanyo lokugoba oluqondisiweyo kwiisampuli ze-weld. Kwiinqwaba eziqhutywa ngokubalulekileyo, senza ne-100% UT ye-weld seam kunye ne-MPI yeenzwane ze-weld. Singabonelela nangovavanyo lweCharpy impact kwi-0°C okanye ngaphantsi ukuba kuchaziwe.

Q: Lingakanani ixesha eliqhelekileyo lokuqalisa iipayipi zokufaka iipayipi zeBanga lesi-2?
A: Ixesha eliqhelekileyo lokukhokela: iintsuku ezingama-25-35 kwiidayamitha ≤ 1,422mm. Kwipleyiti enkulu eqengqelekayo enobubanzi (> 1,422mm): iintsuku ezingama-35-50. Kwiinqwaba ezinde ezidityanisiweyo (ukuya kuthi ga kwi-60m): yongeza iiveki ezi-2.

Isimbuku:Iimitha ezingama-42,000 (iikhilomitha ezingama-42), malunga neetoni ezili-10,800

Iinkcukacha:Iziphelo ezingenanto (isikwere esisikiweyo), i-coal tar epoxy coating (800 microns), uvavanyo lokuthamba (akukho mifantu kwi-1/3 diameter flattening). Uvavanyo lokugoba olukhokelwayo lokuguquguquka kwe-weld. I-100% UT ye-weld seam. I-Charpy impact kwi-0°C (min 27J, ifikelelwe kwi-50-80J). Ukuthe tye ≤ 0.2%. Uhlolo lweqela lesithathu yi-SGS Netherlands.

Isicelo:Ukwandiswa kwesiphelo sesikhongozeli eMaasvlakte 2, kwiZibuko laseRotterdam. Iingqumba zentsimbi zemibhobho zisebenza njengesiseko sodonga lwe-quay (iingqumba ezithwala umthwalo othe nkqo) kunye neengqumba zedolphin ezibophayo (umthwalo osecaleni). Ubunzulu bamanzi kwindawo yokumisa: 18m. Umhlaba unesanti kunye neengqimba zodongwe oluthambileyo.

Imingeni yoBugcisa kunye neZisombululo:

●Ukukhuselwa kokugqwala kwendalo eselunxwemeni– Ukuntywiliselwa emanzini anetyuwa kunye nendawo yokutshiza kwakufuna ugqubuthelo oluhlala ixesha elide. I-Womic efakwe i-epoxy yamalahle (800 microns DFT) eneeleya ezimbini. Ugqubuthelo ludlule uvavanyo lokutshiza ityuwa iiyure ezingama-3,000 (ASTM B117) olune-<2mm creep evela kwi-scribe. Ukufunyanwa kweholide kwi-4kV ngaphandle kokusilela.

●Iinqwaba ezinde zeendawo zokulala amanzi anzulu– Ubude beenqwaba ezifunekayo ze-28m (18m ukuya elwandle + 10m ngaphezulu komgca wodaka). Iindibano eziqhelekileyo ze-12m ziya kufuna ii-slices ezintathu zasentsimini. I-Womic inikeze ii-slices ezinde ze-18m (ipleyiti eqengqelekayo) kwiinqwaba ze-1,016mm, nto leyo enciphisa ii-slices zasentsimini ukusuka kwi-3 ukuya kwi-2 ngenqwaba nganye. Kwiinqwaba ezibalulekileyo zokubopha, sinikeze iinqwaba ezinde ze-28m ngokuhlanganisa iindawo ezimbini ze-14m (ezihlolwe yi-100% UT).

●Uxinzelelo oluphezulu lokuqhuba kwisanti exineneyo– Iprofayili yomhlaba ibandakanya iileya zesanti exineneyo ezine-SPT N-values ezingama-40-60. Uxinzelelo lokuqhuba iinqwaba lusondele kwi-70% yamandla okuvelisa. I-Womic yenze uvavanyo lokugoba olukhokelwayo (i-bend radius 4t, 180°) ngaphandle kokuqhekeka. Iisampulu zovavanyo oluthe tyaba azibonisanga kuqhekeka emva kokugoba kwe-1/2 diameter. Umthengi uxele ukuba akukho kusilela kwe-weld ngexesha lokuqhuba iinqwaba ezingama-3,200.

●Ukuqina kwempembelelo yokufakelwa ebusika– Amaqondo obushushu asebusika eRotterdam anokwehla aye kwi -5°C. I-Womic inike iBanga lesi-2 ukuqina okuphuculweyo kobushushu obuphantsi (iCharpy kwi-0°C min 27J, ifikelele kwi-50-80J). Oku akufunwa yi-ASTM A252 kodwa kongezwe ngumthengi njengesilumkiso.

●Izinto zothutho ukuya eMaasvlakte– Iipayipi zithunyelwa ukusuka eShanghai ukuya eRotterdam ngenqanawa enkulu (iintsuku ezingama-35). Ngenxa yokuba indawo yokulala yayincinci kwisiphelo sendlela, iWomic icwangcise ukuhanjiswa kwezinto ezintathu kwiinyanga ezi-4. Ukuthunyelwa ngakunye kwahambelana neshedyuli yokuqhuba yomenzi-mveliso. Zonke iitoni ezili-10,800 zithunyelwe ngexesha.

● Iziphumo:Ukwandiswa kwesiphelo kugqitywe kwikota yesithathu ka-2024. Zonke iipali ezingama-3,200 ziphumelele uvavanyo lomthwalo oguqukayo (PDA) kunye nomthamo wokuthwala odlula iimfuno zoyilo. Umthengi uthe: “Umgangatho wepayipi yeWomic kunye nokuthembeka kokuhanjiswa kwayo bekugqwesileyo.” IWomic Steel ngoku ngumthengisi ovunyiweyo weeprojekthi zezibuko laseRotterdam zexesha elizayo.
