Ah36 Ah40 ABS Shipbuilding Hlau Phaj

"Ah36 Ah40 ABS Shipbuilding Steel Phaj" yog hais txog shipbuilding steel phaj ntawm AH36 thiab AH40 qib ntawv pov thawj los ntawm American Bureau of Shipping (ABS).

 

AH36 thiab AH40 yog cov hlau tsis tshua muaj zog uas feem ntau siv hauv kev tsim nkoj vim lawv cov khoom siv zoo heev thiab kev sib txuas. Cov hlau no muaj cov yam ntxwv hauv qab no:

 

Cov khoom ntawm AH36 thiab AH40 Steel Phaj:

 

1. Siab zog:

 

AH36 muaj qhov tsawg kawg nkaus yield zog ntawm 355 MPa, thaum AH40 muaj qhov siab tshaj tawm lub zog ntawm 390 MPa. Lub zog no tso cai rau kev tsim kho cov nkoj sib dua thiab ua haujlwm zoo dua yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees.

Lub zog siab ntawm cov hlau no ua rau lawv tuaj yeem tiv taus ntau yam kev thauj khoom thiab kev ntxhov siab los ntawm cov nkoj thaum lub sijhawm ua haujlwm, suav nrog hydrostatic siab, dynamic loads los ntawm nthwv dej thiab cua, thiab cov khoom thauj.

 

2. Zoo Toughness:

 

Ob lub AH36 thiab AH40 steels pom zoo toughness, uas yog qhov tseem ceeb rau kev siv nkoj tsim. Toughness yog hais txog lub peev xwm ntawm cov khoom siv los nqus lub zog thiab tiv thaiv kev puas tsuaj thaum muaj kev cuam tshuam lossis kev thauj khoom tam sim ntawd.

Nyob rau hauv ib puag ncig marine, ships raug rau dynamic rog thiab muaj peev xwm cuam tshuam, yog li muaj steel nrog zoo toughness pab kom muaj kev ruaj ntseg thiab durability ntawm lub nkoj.

 

3. Zoo Weldability:

 

Cov hlau no yog cov weldable heev, tso cai rau kev yooj yim fabrication thiab sib dhos ntawm cov khoom hauv nkoj. Weldability yog qhov tseem ceeb hauv kev tsim cov nkoj vim nws txiav txim siab qhov zoo thiab lub zog ntawm cov pob qij txha welded.

Lub weldability ntawm AH36 thiab AH40 steels tso cai rau siv ntau yam txheej txheem vuam, xws li shielded hlau arc vuam (SMAW), roj hlau arc vuam (GMAW), thiab flux-cored arc vuam (FCAW).

 

4. Corrosion Resistance:

 

Thaum tsis muaj corrosion-resistant ntawm lawv tus kheej, AH36 thiab AH40 steels tuaj yeem tiv thaiv nrog cov txheej txheem lossis lwm yam kev tiv thaiv corrosion los txhim kho lawv cov kav ntev hauv cov dej hiav txwv.

Cov txheej txheem tiv thaiv corrosion feem ntau rau shipbuilding steel muaj xws li tha xim, galvanizing, thiab cathodic tiv thaiv.

 

Daim ntawv thov ntawm AH36 thiab AH40 Steel Phaj hauv Shipbuilding:

 

1. Hull Kev Tsim Kho:

 

AH36 thiab AH40 steel phaj yog dav siv hauv kev tsim cov nkoj hulls. Lub zog siab thiab toughness ntawm cov hlau no ua rau lawv tsim nyog rau kev tiv thaiv lub zog ntawm lub cev thaum lub sij hawm navigation.

Cov hlau phaj yog welded ua ke los tsim cov qauv hull, muab lub zog tsim nyog thiab ruaj khov rau lub nkoj.

 

2. Deck thiab Bulkhead Panels:

 

Cov hlau no kuj tau siv rau lawj plating thiab bulkhead panels, uas ua rau muaj kev ncaj ncees thiab kev faib tawm ntawm lub nkoj.

Deck thiab bulkhead panels ua los ntawm AH36 lossis AH40 steel tuaj yeem tiv taus cov khoom thauj los ntawm cov khoom thauj, cov khoom siv, thiab cov neeg ua haujlwm, nrog rau lub zog muaj zog los ntawm nthwv dej thiab cua.

 

3. Cov qauv ntawm ntug dej hiav txwv:

 

Ntxiv rau kev tsim cov nkoj, AH36 thiab AH40 steels kuj tseem siv rau hauv kev tsim kho ntawm ntug dej hiav txwv platforms thiab lwm cov qauv hauv hiav txwv.

Lub zog siab thiab corrosion kuj ntawm cov hlau no ua rau lawv tsim nyog rau kev tiv thaiv ib puag ncig marine hnyav thiab cov khoom hnyav cuam tshuam nrog kev ua haujlwm sab nrauv.

 

Specification peb muab:

Thickness	2-200 hli
Dav	1000-4000 hli
Ntev	5000-15000 hli

 

 

Qee qhov kev tswj xyuas zoo thiab cov ntawv pov thawj suav nrog:

 

1. Kev kuaj khoom:

 

Tshuaj ntsuam xyuas kom paub tseeb cov tshuaj muaj pes tsawg leeg ntawm cov hlau.

Kev sim tshuab, suav nrog kev sim tensile, kev sim cuam tshuam, thiab kev sim hardness, txhawm rau txheeb xyuas lub zog thiab toughness ntawm cov hlau.

Kev kuaj tsis muaj kev puas tsuaj, xws li kuaj ultrasonic thiab kuaj hluav taws xob, txhawm rau txheeb xyuas cov teeb meem sab hauv hauv cov hlau phaj.

 

2. Daim ntawv pov thawj los ntawm Pawg Neeg Saib Xyuas:

 

ABS daim ntawv pov thawj ua kom ntseeg tau tias cov hlau phaj ua tau raws li cov qauv thiab cov kev cai tsim los ntawm American Bureau of Shipping rau daim ntawv thov kev tsim khoom.

Kev lees paub los ntawm lwm lub koom haum kev faib tawm, xws li Lloyd's Register, Det Norske Veritas (DNV), thiab Bureau Veritas (BV), kuj tseem yuav tsum tau nyob ntawm qhov project specifications thiab tus chij xeev ntawm lub nkoj.
