Raws li Lub Nkoj Cov Qauv Txheej Txheem thiab Cov Txheej Txheem Kev Nyuaj Siab

 

Main Support Structure ntawm Hull
Rau qhov tseem ceeb xws li keel thiab sab hauv qab plating uas dais loj hydrostatic siab thiab yoj cuam tshuam quab yuam, steels uas muaj zog yield zog yog yuav tsum tau. Piv txwv li, AH36, DH36, thiab EH36 series muaj qhov tsawg kawg nkaus lub zog tawm los (qhov tsawg kawg nkaus lub zog ntawm AH36 yog 355MPa), uas tuaj yeem ua kom ntseeg tau tias lawv tsis deform thaum nqa lub luj ntawm lub nkoj thiab cov dej sab nraud, muab cov khoom ruaj khov. longitudinal thiab hauv qab kev txhawb nqa rau lub nkoj.

 

Deck thiab Cargo - nqa cheeb tsam
Lub lawj yuav tsum tau nqa ntau yam khoom xws li qhov hnyav ntawm cov khoom thauj, lub siab ntawm cov khoom siv, thiab qhov cuam tshuam ntawm cov nthwv dej. Cov hlau uas muaj qhov sib npaug zoo ntawm lub zog thiab tawv zoo li AH32 steel yog qhov kev xaiv tsim nyog dua. Nws tuaj yeem tiv thaiv cov yas deformation vim lub hauv zos overloading thaum lub sij hawm cov txheej txheem ntawm cargo tuav thiab tswj cov txheej txheem kev ncaj ncees nyob rau hauv cov kev cuam tshuam ntawm cov nthwv dej, ua kom muaj kev ruaj ntseg ntawm lub nkoj thauj khoom - nqa thiab cov neeg ua haujlwm.

 

Cargo Oil Tank Area (rau Cov Roj Tankers)
Thaum lub tsheb thauj khoom roj tank cheeb tsam ntawm cov roj tanker ruptures, nws yuav ua rau muaj kev huam yuaj loj heev. Yog li ntawd, thaj chaw no muaj cov kev xav tau siab heev rau kev ua haujlwm ruaj khov. High - toughness steels xws li EH32 thiab EH36 tuaj yeem tiv thaiv kev puas tsuaj ntawm cov khoom siv roj tank qauv thaum lub nkoj tab tom sib tsoo, khiav hauv av, lossis raug rau lwm yam kev cuam tshuam tsis txaus ntseeg, ua kom muaj kev nyab xeeb ntawm kev taug kev.

 

Ua ke Machining thiab Vuam Properties

 

Machining Properties
Thaum lub sij hawm lub nkoj - lub tsev txheej txheem, cov hlau yuav tsum mus los ntawm machining txheej txheem xws li txiav, dabtsi yog khoov, thiab sib sau. Yog hais tias cov duab ntawm lub nkoj lub Cheebtsam yog complex, nws yog tsim nyog los xaiv steel nrog zoo machining zog. Qee qhov siab-lub zog marine carbon steels yuav tsum xav txog qhov tsawg kawg nkaus khoov vojvoog thaum lub sijhawm khoov kom tsis txhob muaj cov kab nrib pleb tshwm sim los ntawm kev khoov ntau dhau. Yog li ntawd, raws li cov kev cai tshwj xeeb ntawm cov txheej txheem machining, cov hlau uas tuaj yeem hloov kho rau cov kev ua haujlwm machining no yuav tsum raug xaiv los xyuas kom meej tias cov khoom zoo tom qab machining ua tau raws li lub nkoj - cov qauv tsim.

 

Vuam Khoom
Lub nkoj yog tsim los ntawm ntau cov khoom hlau welded ua ke, yog li kev vuam zoo yog qhov tseem ceeb heev. Xaiv lub siab - lub zog marine carbon steel nrog zoo weldability, thiab cov khoom sib txawv tuaj yeem txuas ruaj khov los ntawm cov txheej txheem vuam tsim nyog (xws li siv qis - hydrogen electrodes lossis roj - shielded vuam). Ntxiv mus, thaum lub sij hawm welding txheej txheem, kev tswj nruj ntawm vuam tsis (xws li vuam tam sim no, voltage, thiab vuam ceev) tuaj yeem ua kom ntseeg tau tias lub zog thiab tawv ntawm cov welded sib koom ua ke zoo ib yam li cov khoom siv hauv paus, txhim kho tag nrho cov kev ntseeg tau ntawm cov khoom siv. nkoj tus qauv. Piv txwv li, rau qee qhov tseem ceeb uas yuav tsum tau ua kom muaj kev sib tw siab, steel nrog kev ruaj khov vuam yuav tsum raug xaiv los xyuas kom meej qhov vuam zoo.

 

 

 

 

 

LR yog hais txog Lloy'd Register of Shipping hauv UK, nrhiav tau nyob rau hauv 1760, thawj tus tswv cuab ntawm International Classification Society.

 

Qib A yog lub nkoj hull siv steel phaj nrog lub zog ib txwm muaj. Nws muaj ABDE 4 qib.

Lub zog tawm los tsis qis dua 235N / M2

 

 

Xa mus rau Cov Qauv Tseem Ceeb thiab Cov Lus Qhia tshwj xeeb

 

Classification Society Standards
Cov koom haum sib txawv (xws li LR - Lloyd's Register, ABS - American Bureau of Shipping, thiab lwm yam) muaj cov qauv qhia ntxaws thiab cov lus qhia tshwj xeeb rau nkoj - tsev steels. Thaum xaiv cov hlau, nws yog ib qho tsim nyog los xyuas kom meej tias cov hlau xaiv tau ua tau raws li qhov yuav tsum tau muaj ntawm cov kev faib tawm hauv zej zog uas lub nkoj belongs. Piv txwv li, LR Qib A steel yog lub nkoj - lub tsev hlau uas ua tau raws li cov qauv ntawm Lloyd's Register. Thaum tsim lub nkoj raws li Lloyd's Register's specifications, hom hlau no tuaj yeem txiav txim siab siv. Cov qauv no suav nrog ntau yam xws li tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev tswj xyuas zoo ntawm cov hlau thiab yog lub hauv paus tseem ceeb rau kev ua kom zoo thiab kev nyab xeeb ntawm lub nkoj.

 

International thiab National Industry Standards
Nyob rau tib lub sijhawm, nws tseem yuav tsum tau xa mus rau cov txheej txheem thoob ntiaj teb (xws li ISO cov qauv) thiab lub teb chaws (xws li lub nkoj - cov qauv tsim ntawm ntau lub teb chaws) cov qauv kev lag luam. Cov qauv no qhia meej txog ntau yam ntawm lub nkoj - lub tsev thiab muab kev qhia ntau dua rau kev xaiv cov khoom tsim nyog - lub zog marine carbon steel. Piv txwv li, nyob rau hauv lub hauv paus ntawm kev ua tau raws li cov kev faib pawg neeg cov qauv, xaiv raws li lub thoob ntiaj teb - siv steel zoo qauv yuav ua kom paub tseeb tias cov zoo thiab siv ntawm cov hlau.
