Cov Lus Nug Feem Ntau (FAQ) - Cov Yeeb Nkab Hlau Marine Piling
Q: Qhov txawv ntawm ASTM A252 GR.3 thiab EN 10248 S355GP rau kev tsim cov piling hauv dej hiav txwv yog dab tsi?
A: ASTM A252 GR.3 (Tus qauv Asmeskas) muaj qhov tsawg kawg nkaus ntawm 345 MPa (50,000 psi), thaum EN 10248 S355GP (Tus qauv European) muaj qhov tsawg kawg nkaus ntawm 355 MPa (51,500 psi). EN 10248 S355GP kuj muaj cov kev txwv tshuaj lom neeg nruj dua me ntsis (qis dua C, P, S) thiab cov kev cai kuaj qhov kub qis qis. Ob qho tib si yog qhov tsim nyog rau cov ntawv thov marine piling. Qhov kev xaiv feem ntau nyob ntawm qhov project specification thiab regional standard preference. Rau cov projects hauv Asmeskas thiab Asia ua raws li API/ASTM cov qauv, GR.3 yog qhov nyiam dua. Rau European, Middle Eastern, thiab African projects, S355GP feem ntau yog teev tseg.
Q: Kuv yuav tsum xaiv cov txheej txheem tsim khoom twg rau kuv qhov project piling pipe - ERW lossis LSAW?
A: Rau sab nraud txoj kab uas hla mus txog 660mm (26 nti), ERW feem ntau pheej yig dua thiab muab sijhawm ua khoom sai dua. Rau txoj kab uas hla los ntawm 508mm txog 3,000mm (20 txog 120 nti), LSAW yog qhov xav tau vim tias ERW thev naus laus zis tsis tuaj yeem tsim cov txoj kab uas hla loj dua no. Rau txoj kab uas hla saum 3,000mm (120 nti), SSAW (kauv vuam) yuav raug txiav txim siab. Cov kev cai ntawm phab ntsa kuj tseem cuam tshuam rau kev xaiv cov txheej txheem - LSAW tuaj yeem ua tiav phab ntsa tuab dua (txog li 50.8mm) piv rau ERW (feem ntau txog li 25.4mm). Womic Steel tuaj yeem qhia txog cov txheej txheem zoo tshaj plaws raws li koj cov kev xav tau tshwj xeeb thiab cov peev nyiaj project.
Q: Lub nplhaib hlau sacrificial yog dab tsi thiab thaum twg yuav tsum siv nws?
A: Lub nplhaib hlau sacrificial yog ib ntu hlau luv luv (feem ntau yog 50-100mm dav, 6-12mm tuab, sib phim cov yeeb nkab OD) vuam rau qhov kawg ntawm lub yeeb nkab piling. Nws nqus cov zog cuam tshuam los ntawm lub rauj tsav pawg, tiv thaiv qhov kawg ntawm cov yeeb nkab los ntawm kev hloov pauv, buckling, lossis tawg. Cov nplhaib sacrificial raug pom zoo rau:
● Kev tsav tsheb nyuaj (xuab zeb tuab, xuab zeb, pob zeb tawg)
● Cov rauj tsoo pawg hnyav (kev cuam tshuam zog siab)
● Cov kav dej nyias nyias (qhov sib piv ntawm txoj kab uas hla mus rau qhov tuab > 50)
● Cov haujlwm tseem ceeb uas kev puas tsuaj ntawm cov kav dej yuav ua rau lub sijhawm qeeb
● Cov kav dej uas yuav tsum tau dej tsis pub dhau tom qab tsav tsheb
Q: Muaj pes tsawg txoj kev xaiv rau cov yeeb nkab marine piling? Koj puas tuaj yeem muab cov kav ntev ntxiv kom txo tau qhov sib txuas ntawm thaj teb?
A: Qhov ntev txheem yog 6m, 12m, thiab 18m. Rau cov haujlwm tob thiab dej hiav txwv, peb muab cov qhov ntev tshwj xeeb txog li 60m (200 feet) nyob ntawm txoj kab uas hla thiab phab ntsa tuab. Qhov ntev ntev ntxiv muaj cov txiaj ntsig zoo: txo tus lej ntawm cov kev sib txuas hauv thaj teb (tus nqi teeb tsa qis dua, lub sijhawm sai dua), kev ua haujlwm txuas ntxiv zoo dua, thiab txo qhov kev pheej hmoo ntawm qhov tsis zoo ntawm weld. Txawm li cas los xij, qhov ntev ntev dua xav tau kev thauj mus los tshwj xeeb (cov thawv tiaj tiaj, cov nkoj loj, lossis cov khoom thauj project) thiab tej zaum yuav muaj cov nqi logistics siab dua. Peb pom zoo kom ua kom zoo dua qhov ntev raws li qhov xav tau ntawm project, kev xaiv thauj mus los, thiab kev txwv kev nkag mus rau qhov chaw. Thov muab koj cov ntsiab lus project rau qhov ntev tshwj xeeb muaj thiab lub sijhawm ua.
Q: Muaj cov kev xaiv txheej dab tsi rau cov yeeb nkab marine piling los tiv thaiv kev xeb ntawm dej hiav txwv?
A: Peb muaj ntau txoj kev xaiv tiv thaiv xeb rau cov chaw nyob hauv dej hiav txwv:

3LPE / 3LPP (Peb Txheej Polyethylene / Polypropylene):Kev tiv thaiv txhua yam zoo tshaj plaws thiab kev tiv thaiv corrosion, qhov tuab ib txwm yog 2.0-4.5 hli, tsim nyog rau cov chaw nyob hauv dej hiav txwv uas muaj kev kub ntxhov.
Cov roj av epoxy:Kev tiv thaiv dej zoo heev thiab kev tiv thaiv cathodic, qhov tuab feem ntau yog 300-600 microns.
Kub Dip Galvanizing:Txheej zinc (feem ntau yog 85-100 microns), muab kev tiv thaiv ntawm cov ntsiab lus puas tsuaj ntawm txheej.
Cov kua Epoxy:Cov txheej txheem siv rau thaj teb rau kev kov thiab kho.
Kev Txheej Txheem Qhov Hnyav ntawm Pob Zeb (CWC):Rau cov kav dej hauv qab dej uas xav tau qhov tsis zoo buoyancy.
Rau feem ntau ntawm cov ntawv thov kev sib txuas ntawm cov dej hiav txwv, 3LPE lossis FBE txheej ua ke nrog kev tiv thaiv cathodic (sacrificial anodes lossis impressed current) yog tus qauv kev lag luam. Kev xaiv txheej nyob ntawm cov dej hiav txwv (kub, salinity, oxygen content), tsim lub neej (20-50 xyoo), thiab cov peev nyiaj project.
Q: Koj puas tuaj yeem muab cov yeeb nkab piling nrog kev tshuaj xyuas sab nraud (SGS, BV, TÜV, DNV, LR)?
A: Yog. Peb txais tos thiab pab txhawb kev tshuaj xyuas los ntawm DNV, BV, SGS, TÜV, ABS, LR, lossis lwm tus neeg sawv cev uas cov neeg siv khoom xaiv tsa thaum lub sijhawm tsim khoom (pom kev sim cov khoom siv raw, kev tshuaj xyuas qhov ntev, NDT, thiab kev tshuaj xyuas zaum kawg) thiab ua ntej xa khoom. 3.2 daim ntawv pov thawj tshuaj xyuas uas tau lees paub los ntawm cov koom haum thib peb tau tso cai raug muab tas li thaum thov. Rau cov haujlwm hauv hiav txwv thiab dej hiav txwv uas xav tau kev pom zoo los ntawm lub koom haum faib tawm (DNV, ABS, LR, BV), peb sib koom tes ncaj qha nrog lub koom haum rau kev tuaj koom ntawm tus neeg soj ntsuam thiab kev pom zoo ntawm cov ntaub ntawv.
Q: Yuav tsum muaj kev sim tsis puas tsuaj (NDT) dab tsi rau cov yeeb nkab marine piling?
A: Rau ASTM A252 GR.3, cov kev cai NDT txheem yog txwv (tsis muaj NDT yuav tsum tau ua rau qib txheem). Txawm li cas los xij, rau cov ntawv thov tseem ceeb hauv hiav txwv thiab ntug dej hiav txwv, peb pom zoo thiab tuaj yeem muab:
Kev Ntsuas Ultrasonic 100% (UT)ntawm cov hlua khi thiab cov yeeb nkab lub cev (rau LSAW thiab ERW)
Kev Tshuaj Xyuas Cov Khoom Sib Nqus (MPI)ntawm cov ntiv taw vuam thiab thaj chaw kub-cuam tshuam
Kev Kuaj Mob X-ray (RT)ntawm qhov txuas ntawm qhov vuam (qhov chaw lossis tag nrho ntev)
Kev luam theej duab UT laminarntawm cov npoo phaj ua ntej vuam (rau LSAW)
Rau EN 10248 S355GP, kev kuaj ntxiv suav nrog UT lossis MPI yuav raug teev los ntawm tus neeg yuav khoom. Peb ib txwm pom zoo kom tham txog cov kev cai ntawm NDT thaum lub sijhawm hais nqe kom paub tseeb tias qhov kev kuaj thiab cov ntaub ntawv raug.
Q: Qhov ntev tshaj plaws uas koj tuaj yeem muab rau cov yeeb nkab loj (piv txwv li, 2,000mm OD × 25mm WT) yog dab tsi?
A: Rau 2,000mm OD × 25mm WT, peb tuaj yeem muab ib qho ntev txog li 24m (kwv yees li 80 feet) rau LSAW txheej txheem. Rau cov kab uas hla saum toj no 1,500mm, qhov ntev tshaj plaws feem ntau yog txwv los ntawm qhov muaj phaj loj thiab kev txwv kev thauj mus los. Thov hu rau peb nrog koj cov kev xav tau tshwj xeeb (OD, WT, ntev, ntau npaum li cas) rau kev ntsuam xyuas peev xwm ntxaws thiab cov lus hais lub sijhawm ua. Rau cov haujlwm xav tau qhov ntev tshaj qhov txwv kev thauj mus los tus qauv (piv txwv li, >24m rau cov kab loj), peb tuaj yeem pab nrog kev npaj logistics project suav nrog barge lossis kev npaj thauj mus los tshwj xeeb.
Q: Koj puas muab kev pab txiav kom ntev rau cov yeeb nkab piling? Koj tuaj yeem ua tiav qhov kam rau siab li cas?
A: Yog. Peb muab kev txiav kom raug rau qhov ntev uas cov neeg siv khoom teev tseg nrog kev kam rau siab. Kev kam rau siab qhov ntev yog +50mm / -0mm raws li ASTM A252 thiab EN 10248 xav tau. Rau cov haujlwm uas xav tau kev kam rau siab ze dua, peb tuaj yeem ua tiav ± 3mm rau txoj kab uas hla mus txog 660mm (ERW) thiab ± 5mm rau txoj kab uas hla loj dua (LSAW) nrog kev ua tiav ntxiv. Kev txiav tuaj yeem ua raws li qhov kawg beveling (30 ° -35 ° bevel lub kaum sab xis nrog 1.6 hli ± 0.8 hli tsaws) rau kev vuam taub qab teb lossis qhov kawg tiaj tiaj raws li qhov xav tau. Thov qhia koj cov kev xav tau kev kam rau siab ntawm theem hais lus.
Q: Lub sijhawm ua khoom siv rau ASTM A252 GR.3 lossis EN 10248 S355GP marine piling pipe yog dab tsi?
A: Lub sijhawm ua tus qauv rau cov yeeb nkab piling uas tsim los ntawm lub Hoobkas (tsis yog los ntawm Tshuag) yog kwv yees li 30-45 hnub rau cov txheej txheem ERW thiab 45-60 hnub rau cov txheej txheem LSAW, nyob ntawm seb muaj pes tsawg, txoj kab uas hla, phab ntsa tuab, thiab cov kev cai kuaj tshwj xeeb.
