Cov Lus Nug Feem Ntau:

Q: Qhov txawv ntawm ASTM A252 Qib 2 thiab Qib 3 rau kev piling yog dab tsi?
A: Qib 3 muaj zog dua (345 MPa vs 240 MPa yield) thiab siv rau cov hauv paus tob dua lossis cov kev xav tau siab dua. Qib 2 pheej yig dua thiab txaus rau feem ntau cov ntawv thov hauv paus dav dav (choj, tsev, chaw nres nkoj). Xaiv Qib 2 rau cov khoom thauj txheem, Qib 3 rau cov khoom hnyav lossis tsav tsheb tob dua.

Q: Koj puas muab cov kav dej A252 Qib 2 nrog cov txheej galvanized?
A: Yog. Peb muab kev galvanizing kub-dip raws li ASTM A123. Qhov ntev tshaj plaws rau kev galvanizing yog 12.5m. Yog tias cov pawg ntev dua, peb xav kom siv txheej epoxy lossis txheej bituminous.

Q: Qhov ntev tshaj plaws uas koj tuaj yeem tsim tau rau Qib 2 piling yeeb nkab yog dab tsi?
A: Qhov ntev tshaj plaws ntawm ib ntu yog 18m (JCOE) lossis 24m (UOE). Rau qhov ntev txog 60m, peb vuam ntau ntu txij thaum pib mus txog thaum kawg nrog kev vuam SAW circumferential tag nrho (100% UT tshuaj xyuas). Qhov no yog ib txwm muaj rau cov monopiles cua offshore.

Q: ASTM A252 puas xav tau kev kuaj hydrostatic?
A: Tsis yog. ASTM A252 tsis tas yuav tsum tau kuaj hydrostatic vim tias cov kav dej piling tsis yog cov uas muaj kev siab. Txawm li cas los xij, yog tias koj qhov project xav tau kev kuaj hydrostatic (piv txwv li, rau kev sib xyaw ua ke ntawm piling thiab kev thauj mus los ntawm cov kua dej), peb tuaj yeem ua nws ntawm tus nqi ntxiv.

Q: Cov txheej txheem twg raug pom zoo rau kev teeb tsa hauv dej hiav txwv hauv dej ntsev?
A: Yog siv rau hauv dej hiav txwv, siv cov thee tar epoxy (600-800 microns) lossis iav flake epoxy. Rau thaj chaw uas muaj dej txaws, peb pom zoo kom siv FBE lossis cov txheej epoxy tuab. Rau cov dej qab zib lossis av, cov yeeb nkab dub lossis cov nplaim uas muaj roj feem ntau txaus.

Q: Koj ua li cas thiaj paub tseeb tias cov welds muaj sia nyob rau kev tsav tsheb rauj?
A: Peb ua qhov kev sim flattening (yuav tsum tau ua) thiab kev sim khoov coj ntawm cov qauv weld. Rau cov pawg tsav tseem ceeb, peb kuj ua 100% UT ntawm weld seam thiab MPI ntawm weld toes. Peb kuj tuaj yeem muab kev sim cuam tshuam Charpy ntawm 0 ° C lossis qis dua yog tias tau teev tseg.

Q: Lub sijhawm ua cov kav dej qib 2 yog dab tsi?
A: Lub sijhawm ua tus qauv: 25-35 hnub rau cov kab uas hla ≤ 1,422mm. Rau cov phaj loj uas dov tau (> 1,422mm): 35-50 hnub. Rau cov pawg ntev uas vuam (txog li 60m): ntxiv 2 lub lis piam.
