CCS Qib D Shipbuilding Steel Sheet

CCS Qib C Shipbuilding Steel Sheet

CCS Qib D shipbuilding steel phaj feem ntau yog siv los tsim cov nkoj thiab cov nkoj uas caij nkoj hauv dej hiav txwv txias hauv qab qis dua 20 centigree.

GNEE steel foucs ntawm dov dav dav shipbuilding phaj, txog niaj hnub no, peb tuaj yeem dov qhov siab tshaj plaws thickness rau nkoj tsim phaj CCS Qib D yuav tsum yog 300 hli, thiab qhov siab tshaj plaws yuav tsum txog 4200mm.

Rau lub thickness saum toj no 40 hli, peb engineers qhia cov neeg muas zaub txais kev kho cua sov zoo rau CCS Qib D steel daim hlau.

Technical Requirements & Kev Pab Ntxiv:
♦ Kev ntsuam xyuas siab
♦ Z-Test (Z15,Z25,Z35)
♦ Qhov ntsuas kub tsis tshua muaj kev cuam tshuam
♦ Ultrasonic kuaj raws li ASTM A435, A577, A578
♦ Muaj ntawv pov thawj los ntawm ABS, LR, GL, BV, DNV, KR, NK, CCS, RINA
♦ Tshaj tawm Orginal Mill xeem daim ntawv pov thawj raws li EN 10204 FORMAT 3.1/3.2
♦ Kev txhaj tshuaj blasting thiab pleev xim, txiav thiab vuam raws li tus neeg siv khoom kawg

CCS qib D marine steel phaj yog hais txog ib hom hlau phaj uas ua tau raws li qhov yuav tsum tau muaj kev faib tawm ntawm Tuam Tshoj Classification Society (CCS) rau kev siv hauv marine daim ntaub ntawv, tshwj xeeb tshaj yog rau qib D. CCS yog ib qho kev lees paub kev faib tawm hauv zej zog lub luag haujlwm rau kev teeb tsa cov qauv thiab cov cai rau cov nkoj thiab cov qauv sab nrauv hauv Suav teb.

CCS qib D marine steel phaj feem ntau yog siv rau hauv kev tsim cov nkoj hulls thiab lwm cov qauv marine. Nws muaj lub zog zoo thiab lub zog toughness, ua rau nws tsim nyog rau kev tiv thaiv cov xwm txheej hnyav hauv hiav txwv. Cov phaj steel yog tsim los ntawm cov kev cai tshwj xeeb uas tau teev tseg los ntawm CCS, ua kom muaj kev ua raws li kev lag luam cov cai thiab cov qauv kev nyab xeeb.

Qib D qhia txog qib ntawm tensile lub zog thiab cuam tshuam toughness cov hlau phaj muaj. Nws qhia tau hais tias cov khoom muaj qhov tsawg kawg nkaus lub zog ntawm 235 MPa (megapascals) thiab lub zog tensile yam tsawg kawg nkaus ntawm 400-520 MPa. Cov khoom siv kho tshuab no ua rau CCS qib D marine steel daim hlau tsim nyog rau ntau yam qauv ntawm cov nkoj thiab cov chaw sab nrauv.

Ntxiv rau nws cov khoom siv kho tshuab, CCS qib D marine steel phaj tau dhau los ua cov txheej txheem kuaj thiab tshuaj xyuas kom zoo thiab ua raws li kev faib tawm hauv zej zog cov qauv. Qhov no suav nrog kev kuaj xyuas qhov ntev, kev tshuaj xyuas qhov muag, kev kuaj xyuas ultrasonic, thiab kev ntsuas khoom siv tshuab.

Thaum xaiv CCS qib D marine steel daim hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog tej yam xws li phaj thickness, dav, ntev, thiab lwm yam uas yuav tsum tau teev tseg rau ib qhov project lossis daim ntawv thov.

Zuag qhia tag nrho, CCS qib D marine steel daim hlau muab cov kev daws teeb meem txhim khu kev qha thiab ruaj khov rau kev tsim kho hauv hiav txwv, ua tau raws li cov kev cai nruj uas tau teev tseg los ntawm Tuam Tshoj Classification Society rau kev nyab xeeb thiab kev ua haujlwm zoo hauv hiav txwv.

CCS shipbuilding steel phaj feem ntau muab faib ua plaub qib: A, B, D, thiab E. Cov qib no muaj qhov sib txawv yam tsawg kawg nkaus yield thiab tensile zog thiab yog categorized raws li lawv cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom. CCS Qib A thiab CCS Qib B muaj qhov tsawg kawg nkaus lub zog ntawm 235 MPa (34,000 psi) thiab lub zog tensile yam tsawg kawg nkaus ntawm 400-520 MPa (58,000-75,000 psi){9}},000 psi), thaum CCS Class D thiab CCS Class E0 muaj qhov tsawg kawg nkaus 4 psi, Lub zog tensile yam tsawg kawg nkaus ntawm 440-570 MPa (64,000-83,000 psi).

Peb muaj txaus CCS Qib D Shipbuilding Steel Sheet hauv Tshuag, thiab peb tuaj yeem kho nws raws li koj xav tau.
