FAQ (Cov lus nug nquag nug)
Q1: Dab tsi yog qhov txawv ntawm X46N thiab zoo tib yam X46 steel yeeb nkab?
Qhov tseem ceeb sib txawv nyob hauvKev kho cua sov thiab kev ua haujlwm zoo. X46N tau txais kev kho kom zoo los kho cov qauv nplej thiab tshem tawm cov kev ntxhov siab uas nyob rau hauv qhov chaw, xa cov khoom zoo heev uas tsis tshua muaj siab - kub toughness, ruaj khov weldability thiab superior qaug zog tsis kam. Ordinary X46 kav uas tsis muaj qhov normalization muaj qhov tsis zoo toughness thiab muaj kev ntxhov siab tawg, tsuas yog haum rau ib txwm muaj - qhov kub thiab qis - siab ua haujlwm. X46N muaj feem xyuam rau qhov hnyav qis-kub, siab{10}}siab thiab corrosive ib puag ncig.
Q2: Yuav ua li cas xaiv ntawm PSL2 thiab PSL1? Lawv puas tuaj yeem siv sib xyaw?
Kev siv sib tov tsis pom zoo. PSL2 yog cov qib siab zoo steel qib nrog qhov yuav tsum tau qis- ntsuas qhov kub thiab txias, kev tiv thaiv kev tiv thaiv nruj dua thiab tag nrho- kev tiv thaiv tsis yog- kev ntsuas kev puas tsuaj, tsim kom ntev- roj & roj kis tau tus mob, siab- siab, qis- kub thiab cov haujlwm tseem ceeb. PSL1 tsis muaj qhov yuav tsum tau muaj kev cuam tshuam rau qhov yuav tsum tau ua thiab xoob qhov ntsuas qhov siab, tsuas yog rau qhov qis qis - siab & ib txwm - kev thauj mus los ntawm cov dej kub. PSL2 yog qhov yuav tsum tau ua rau cov haujlwm tseem ceeb, kev txiav txim xa tawm thiab siab - ua haujlwm siab.
Q3: Yuav ua li cas xaiv peb cov tshuaj tiv thaiv -corrosion txheej rau kev ua haujlwm sib txawv?
1. 3 LPE txheej: Kev xaiv hwm zoo rau ntev -qhov deb faus roj & roj kav, ntsev- alkali av thiab siab - thaj chaw corrosion, kev pab lub neej tshaj 50 xyoo nrog cov nqi siab dua rau kev ua haujlwm ntev-; 2.Dub Varnish Txheej: Kev xaiv nyiaj txiag rau cov dej hauv nroog & dej thiab cov kav dej faus zoo tib yam nrog kev ua haujlwm zoo heev; 3.Kub-Dip Galvanized Txheej: Zoo tagnrho rau sab nraum zoov cov kav dej siv hluav taws xob thiab cov chaw nyob nruab nrab ntawm qhov nruab nrab corrosion nrog cov nqi tu qis.
Q4: Puas muaj kev ua haujlwm customized? Lub voj voog xa khoom yog dab tsi?
Kev hloov kho tag nrho yog txaus siab, suav nrog tsis yog -txoj kab uas hla & phab ntsa thickness, ruaj ntev, beveling, tshwj xeeb thickened txheej thiab sab hauv & sab nrauv kho. Cov lus qhia tshwj xeeb yog nyob rau hauv Tshuag nrog 3-5 hnub xa khoom; customized thiab tshwj xeeb txheej txiav txim yuav siv sij hawm 7-10 hnub, txhawb loj batch ntau lawm.
Q5: Cov yeeb nkab puas tuaj yeem tsim los ntawm qhov kub thiab txias? Puas yog pob txha tawg puas yuav tshwm sim hauv qhov chaw txias?
Tsis muaj pob txha tawg tshwm sim. Featuring normalized X46N txheej txheem thiab PSL2 hwm qib, cov yeeb nkab muaj tus qauv 0℃Charpy cuam tshuam lub zog Ntau dua los yog sib npaug rau 27J thiab zoo heev qis-kub toughness, tiv taus qhov kub tsis txias mus rau -40℃. Nws hloov kho kom haum rau lub caij ntuj no qis- qhov kub thiab txias kev tsim kho nyob rau sab qaum teb thaj tsam thiab txias - cheeb tsam cov kav xa dej, ua haujlwm raws li cov kav dej uas tsis muaj qhov kub thiab txias.
Q6: Puas yog cov tshuaj tiv thaiv- cov khaubncaws sab nraud povtseg hnav- tiv taus thiab kev laus -resistant? Puas yuav txheej tev tawm thaum thauj thiab teeb tsa?
Tag nrho peb txheej txheej tau txais kev lag luam siab - txheej txheem txheej txheem nrog kev ruaj ntseg ruaj khov . 3LPE txheej nta ultra- muaj zog adhesion thiab cuam tshuam tiv thaiv av kev sib txhuam; dub kua roj vanish zaj duab xis yog ntom thiab saj zawg zog; galvanized txheej cov ntaub ntawv metallurgical bonding tsis tev. Tsis muaj txheej txheej puas los yog tev tshwm sim raws li kev thauj mus los, hoisting thiab installation. Cov txheej txheej muaj zog muaj rau kev tsim kho hnyav.
Q7: Cov khoom puas txhawb nqa thib peb -kev kuaj xyuas tog? Txoj cai warranty yog dab tsi?
Txhua yam khoom txhawb nqa tag nrho SGS thib peb- tog rov- kev tshuaj xyuas thiab ua raws li API 5L cov qauv. Warranty: 15- xyoo warranty rau steel substrate, tshaj 30- xyoo warranty rau 3LPE txheej, tshaj 20- xyoo warranty rau galvanized txheej, thiab 10-xyoo warranty rau dub varnish txheej. Lub neej kev pab cuam tom qab muag yog muab rau kev puas tsuaj rau tib neeg thiab kev siv tsis ua phem.
