CCS Qib E Shipbuilding Steel Phaj - Qhov Kawg Qis -Temperature Marine Structural Steel

CCS Qib E shipbuilding steel phaj yog aib txwm -strength marine structural steeltau ntawv pov thawj los ntawm Tuam Tshoj Classification Society (CCS). Raws li qhov siab tshaj - cov ntaub ntawv qib siab nyob rau hauv CCS dav dav - lub zog shipbuilding steel series (Qib A, B, D, thiab E), CCS Qib E yog tsim tshwj xeeb kom xa tau tshwj xeeb qis- kub toughness thiab kev ntseeg tau ntawm cov qauv hauv cov dej hiav txwv huab cua.

Cov phaj hlau no tau siv dav hauv kev tsim cov nkoj hulls, offshore platforms, thiab cov khoom siv hauv hiav txwv uas yuav tsum tau tiv thaiv dej hiav txwv. Nws yog qhov kev xaiv zoo tshaj plaws thaum qhov project specifications xav tau kev txhim khu kev qha ntawm qhov kub thiab txias li tsawg-40 degree.

Vim li cas thiaj xaiv Qib E?
Thaum tag nrho plaub qib sib piv cov txiaj ntsig thiab lub zog tensile, qhov sib txawv tseem ceeb yogqis-kub los cuam tshuam toughness. CCS Qib E yog qib nkaus xwb hauv cov koob no uas tau lees paub qhov kev ua tau zoo ntawm -40 degree, ua rau nws yog qhov yuav tsum tau xaiv rau cov nkoj thiab cov khoom siv sab nrauv ua haujlwm hauv cov dej txias lossis raug kev ntxhov siab ib puag ncig.

Xaiv CCS Qib E tsis yog hais txog kev ua kom tau raws li qhov tshwj xeeb - nws yog hais txogkev pheej hmoo mitigation. Hauv Arctic tej yam kev mob, cov khoom tsis ua hauj lwm tsis yog ib qho kev xaiv. Qib E muab cov kev lav phib xaub thiab pov thawj kev ntseeg siab uas tiv thaiv koj cov neeg coob, koj cov khoom muaj nqis, thiab koj lub koob npe nrov.

FAQ

01.Qhov txawv ntawm CCS Qib E thiab Qib D yog dab tsi?

Ob leeg muaj tib qhov tawm los (235 MPa) thiab lub zog tensile (400-520 MPa). Qhov sib txawv tseem ceeb yog qhov ntsuas qhov kub thiab txias: Qib D raug kuaj ntawm -10 degree, thaum Qib E raug kuaj ntawm-40 degree, ua rau Qib E tsuas yog xaiv rau Arctic thiab sub- ib puag ncig Arctic.

02.CCS Qib E puas tuaj yeem welded yam tsis muaj preheating?

Yog lawm, vim nws cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.18%), CCS Qib E muaj kev sib txuas zoo heev. Txawm li cas los xij, rau daim hlau tuab dua 40mm lossis nyob rau hauv qhov chaw txias, qhov preheat ntawm 50-100℃raug pom zoo los tiv thaiv hydrogen-induced cracking. Ib txwm ua raws cov txheej txheem vuam pom zoo (WPS).

03.Koj puas muab daim phiaj nrog - tog thib peb soj ntsuam?

Yog lawm. Peb txhawb SGS, BV, ABS, DNV, thiab LR tshuaj xyuas. Peb tseem tuaj yeem npaj ua pov thawj rau cov khoom siv kho tshuab thiab tshuaj ntsuam xyuas ntawm peb lub zeb. Txhua qhov kev tshuaj xyuas tau koom tes nrog koj lub sijhawm ua haujlwm.

04.Yam tsawg kawg nkaus kom muaj nuj nqis (MOQ) yog dab tsi?

Peb MOQ yog 10 tons ib qhov loj me. Rau kev txiav txim mus sib hais lossis ceev me me -batch yuav tsum, peb tuaj yeem ua raws li tsawg li 3 tons. Hu rau peb pab neeg muag khoom rau kev npaj kev cai.
