LR AW Steel

LR A Steel, tseem hu ua Lloyd's Register pom zoo steel, suav nrog ntau qib tseem ceeb steel. Nov yog qhov tob saib ntawm nws cov qib steel tseem ceeb, kev siv, cov qauv steel, thiab txoj kev kho saum npoo:

 

Main Steel Qib:

 

LR AH32: Cov hlau muaj zog no tau siv dav hauv kev tsim cov nkoj rau cov qauv ntawm lub nkoj, lub lawj, thiab cov bulkheads. Nws muaj cov khoom siv kho tshuab zoo heev, suav nrog lub zog siab tawm los thiab zoo toughness.

LR AH36: Zoo ib yam li AH32, AH36 kuj yog ib qho kev xaiv nrov rau kev tsim nkoj. Nws muaj lub zog ntau dua thiab tsim nyog rau cov ntawv thov uas yuav tsum muaj kev ncaj ncees ntau dua.

LR DH32 thiab LR DH36: Cov qib no yog tsim los rau cov ntawv thov uas xav tau kev ua kom muaj zog, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias. Lawv feem ntau siv nyob rau hauv cov qauv ntawm ntug dej hiav txwv thiab cov nkoj ua haujlwm hauv thaj chaw txias.

 

Cov ntawv thov tseem ceeb:

 

Shipbuilding: LR A steel yog siv dav hauv kev tsim kho ntawm ntau hom nkoj, nrog rau cov nkoj thauj khoom, cov nkoj thauj khoom, thiab cov neeg caij nkoj. Lub zog siab thiab ua haujlwm ntev ntawm cov hlau no ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub nkoj cov qauv.

Offshore Structures: Offshore platforms, roj rigs, thiab cua turbines feem ntau siv LR A steel vim nws muaj peev xwm tiv taus qhov hnyav marine ib puag ncig thiab hnyav hnyav.

Kev tsim kho choj: Qee zaum, LR A steel tuaj yeem siv rau hauv kev tsim cov choj, tshwj xeeb tshaj yog nyob rau hauv cov chaw ntug dej hiav txwv lossis raug rau qhov chaw muaj corrosive.

Cov qauv hlau:
Lloyd's Register tau tsim cov qauv nruj rau LR A steel los xyuas kom meej nws qhov zoo thiab kev ua tau zoo. Cov qauv no suav nrog cov khoom xws li tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev ntev, thiab cov txheej txheem vuam. Cov qauv raug hloov kho tsis tu ncua kom muaj kev cuam tshuam txog kev nce qib thev naus laus zis tshiab thiab cov kev xav tau ntawm kev lag luam.

 

Kev kho saum npoo:

 

Kev pleev xim: Ib txoj hauv kev zoo tshaj plaws rau LR A steel yog pleev xim. Lub tshuab pleev xim tsim nyog tuaj yeem muab kev tiv thaiv corrosion, UV hluav taws xob, thiab puas. Kev xaiv xim yog nyob ntawm daim ntawv thov tshwj xeeb thiab ib puag ncig.

Galvanizing: Kub-dip galvanizing kuj tseem siv tau los tiv thaiv LR A hlau los ntawm corrosion. Cov txheej txheem no yog immersing cov hlau nyob rau hauv ib da dej ntawm molten zinc, uas tsim ib tug tiv thaiv txheej rau saum npoo.

Kev Txhaj Tshuaj Blasting thiab Primer Application: Kev txhaj tshuaj blasting feem ntau yog siv los ntxuav cov hlau saum npoo thiab tshem tawm xeb thiab nplai. Tom qab txhaj tshuaj blasting, primer yog siv los muab kev tiv thaiv thawj zaug thiab txhim kho cov adhesion ntawm cov txheej tom ntej.

Kev tiv thaiv Cathodic: Qee qhov xwm txheej, kev tiv thaiv cathodic tuaj yeem siv nrog rau lwm txoj kev kho saum npoo. Qhov no suav nrog kev siv hluav taws xob tsis zoo rau cov hlau los tiv thaiv corrosion los ntawm kev txi ib qho anode.
