DNV Marine Steel Phaj Qib FH32 Zoo

DNV Marine Steel Phaj Qib FH32 yog cov khoom siv hlau zoo nrog cov yam ntxwv tshwj xeeb thiab kev siv hauv kev lag luam marine.

 

Tshuaj muaj pes tsawg leeg:
Cov qib steel no feem ntau muaj cov tshuaj tiv thaiv kab mob kom ntseeg tau tias nws ua tau zoo. Nws muaj cov ntsiab lus xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab ntau yam alloying ntsiab nyob rau hauv cov kev txwv tshwj xeeb. Piv txwv li, cov ntsiab lus carbon feem ntau yog khaws cia qis kom tswj tau qhov weldability thiab toughness.

 

Mechanical Properties:

 

Tensile zog: Nws muaj qee qhov tensile lub zog ntau yam, uas ua rau nws tuaj yeem tiv taus lub zog ntawm cov qauv hauv hiav txwv. Lub zog tensile muab lub peev xwm tiv taus ncab thiab tawg hauv qab load.

Yield zog: Lub zog tawm los qhia qhov kev ntxhov siab uas cov hlau pib deform plastically. Lub zog tawm los ntau dua ua kom muaj kev ncaj ncees ntawm cov khoom siv marine.

Impact Toughness: Cov kev cuam tshuam zoo toughness yog qhov tseem ceeb rau kev tiv thaiv kev thauj mus los thiab kev cuam tshuam tam sim ntawd, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig marine qhov twg nthwv dej thiab kev sib tsoo tuaj yeem tshwm sim. FH32 steel qib yog tsim los kom muaj kev cuam tshuam txaus toughness ntawm ntau qhov kub thiab txias.

 

Corrosion Resistance:
Nyob rau hauv marine ib puag ncig, corrosion yog ib qho kev txhawj xeeb tseem ceeb. DNV Marine Steel Phaj Qib FH32 feem ntau yog kho lossis alloyed los txhim kho nws cov corrosion kuj. Qhov no yuav pab kom ntev lub neej kev pab cuam ntawm marine lug thiab txo nqi txij nkawm.

Daim ntawv thov:

 

Shipbuilding: Siv nyob rau hauv kev tsim cov nkoj hulls, decks, bulkheads, thiab lwm yam structural Cheebtsam. Nws lub zog siab thiab toughness ua rau nws tsim nyog rau kev tiv thaiv cov dej hiav txwv hnyav.

Offshore Structures: Siv nyob rau hauv kev tsim kho ntawm ntug dej hiav txwv platforms, roj rigs, thiab cua turbines. Nws tuaj yeem tiv taus qhov corrosive marine ib puag ncig thiab cov khoom hnyav los ntawm nthwv dej, cua, thiab khoom siv.

Marine Pipelines: tuaj yeem siv rau kev tsim cov kav dej hiav txwv uas thauj cov roj, roj, thiab lwm yam khoom siv. Cov hlau tsis muaj zog thiab cov khoom siv kho tshuab ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov kav dej no.

 

Quality Assurance:
Raws li cov khoom lag luam tau lees paub los ntawm DNV (Det Norske Veritas), nws tau dhau los ua cov txheej txheem tswj xyuas zoo thiab tshuaj xyuas. Qhov no ua kom cov phaj hlau ua tau raws li cov qauv tsim nyog thiab cov lus qhia tshwj xeeb rau kev siv dej hiav txwv.
