RINA Marine Steel Phaj Qib A

 

RINA Marine Steel Phaj Qib A yog hom hlau phaj ntawv pov thawj los ntawm Italian Classification Society (RINA) rau kev siv dej hiav txwv.

 

Cov yam ntxwv yooj yim:

 

Siv: Feem ntau yog siv rau hauv kev tsim cov nkoj hulls, decks, bulkheads, thiab lwm yam qauv ntawm cov nkoj. Nws kuj tseem tsim nyog rau cov qauv kev lag luam marine xws li offshore platforms thiab docks.

Yam ntxwv: Qib no ntawm steel phaj muaj lub zog zoo, toughness, thiab corrosion kuj, ua rau nws tsim nyog rau withstanding hnyav marine ib puag ncig.

 

Tshuaj muaj pes tsawg leeg:

 

Nws muaj cov ntsiab lus tshwj xeeb xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab lwm yam alloying ntsiab. Cov muaj pes tsawg leeg yog ua tib zoo tswj kom ntseeg tau tias cov khoom siv kho mob xav tau thiab tiv thaiv corrosion.

 

Mechanical Properties:

 

Lub zog: Nws muaj lub zog muaj zog thiab tensile zog. Lub zog tawm los qhia qhov kev ntxhov siab uas cov hlau pib deform mus tas li, thaum lub zog tensile sawv cev rau qhov siab tshaj plaws ntawm cov hlau tuaj yeem tiv taus ua ntej tawg.

Toughness: Ua kom pom qhov zoo toughness ntawm qhov kub thiab txias, kom ntseeg tau tias cov hlau tuaj yeem tiv taus qhov cuam tshuam thiab kev thauj khoom sai sai yam tsis tau tawg yooj yim.

Ductility: Muaj ductility txaus kom tso cai rau deformation thaum lub sij hawm fabrication thiab kev pab cuam yam tsis muaj cracking.

Corrosion Resistance:

 

Vim nws muaj pes tsawg leeg thiab kev kho mob, Qib A steel phaj muaj corrosion kuj zoo rau seawater, ntsev tsuag, thiab lwm yam corrosive hais nyob rau hauv marine ib puag ncig. Qhov no pab txhawm rau txuas lub neej kev pabcuam ntawm cov nkoj thiab cov qauv hauv hiav txwv.

 

Vuam thiab Fabrication:

 

Cov hlau phaj yog tsim rau ntau txoj kev vuam, nrog rau cov hlau thaiv hlau arc vuam (SMAW), roj hlau arc vuam (GMAW), thiab flux-cored arc vuam (FCAW). Cov txheej txheem vuam kom raug thiab kev tswj xyuas zoo yog qhov tseem ceeb los xyuas kom meej qhov kev ncaj ncees ntawm cov pob qij txha.

Nws tuaj yeem tsim tau yooj yim rau hauv cov duab sib txawv thiab ntau thiab tsawg siv cov txheej txheem kev tsim xws li txiav, khoov, thiab dov.

 

Kev Tswj Xyuas Zoo thiab Ntawv Pov Thawj:

 

RINA ua cov kev tswj xyuas nruj nruj thaum lub sijhawm tsim khoom thiab tshuaj xyuas qib A steel daim hlau. Qhov no suav nrog kev tshuaj xyuas tshuaj, kev sim tshuab, thiab kev tshuaj xyuas qhov ntev kom ntseeg tau tias ua raws li cov qauv thiab cov qauv tshwj xeeb.

Daim ntawv pov thawj los ntawm RINA muab kev lees paub ntawm qhov zoo thiab kev ua haujlwm ntawm cov hlau phaj rau kev siv dej hiav txwv.
