ASTM A131 Nkoj Tsim Hlau Phaj yog cov qauv hlau phaj qauv rau kev tsim nkoj tsim los ntawm American Society for Testing and Materials (ASTM). Nov yog cov ncauj lus kom ntxaws txog nws:
Scope ntawm daim ntawv thov:
Feem ntau yog siv rau cov txheej txheem steel, phaj, tuav thiab rivet cov ntaub ntawv nyob rau hauv shipbuilding.
Kev faib tawm ntawm steel qib:

 

 

 

Ordinary zog qib: suav nrog qib A, B, D, CS thiab E. Cov ntsiab lus qis qis qis yog 34 ksi (235MPa). Cov qib sib txawv tuaj yeem muaj qhov sib txawv ntawm qhov toughness thiab haum rau qhov sib txawv ntawm lub nkoj cov qauv. Piv txwv li, qib A yog qib pib lub zog zoo tib yam thiab siv rau hauv qhov chaw uas qhov kev xav tau ntawm lub zog tsis yog siab tshwj xeeb; Qib E yuav siv tau rau hauv cov khoom tseem ceeb uas yuav tsum tau muaj zog toughness.

Qib siab zog: Muaj qib AH, DH, EH thiab FH. Cov ntsiab lus qis qis tshaj tawm yog 46 ksi (315MPa), 51 ksi (350MPa) lossis 57 ksi (390MPa) feem. Cov qib high-strength steel daim hlau no tuaj yeem ua tau raws li cov kev cai siv ntawm cov nkoj hauv ib puag ncig hnyav. Piv txwv li, cov nkoj loj thauj mus los hauv hiav txwv thiab cov roj tankers nrog cov kev xav tau siab rau cov qauv siv lub zog siv cov qib siab zog.
Cov yam ntxwv ua haujlwm:

Siab zog: Nws muaj kev ua tau zoo ntawm lub zog siab, uas tuaj yeem ua kom muaj kev ruaj khov zoo dua thiab kev nyab xeeb ntawm cov nkoj thaum lub sij hawm mus sij hawm ntev hauv qhov chaw hnyav. Piv txwv li, thaum ntsib cov dej hiav txwv hnyav xws li cua daj cua dub thiab nthwv dej, cov qauv hull tuaj yeem nyob ruaj khov thiab tsis yooj yim deformed lossis puas.

Corrosion kuj: Kev siv cov ntaub ntawv zoo thiab cov cuab yeej tiv thaiv corrosion siab heev tuaj yeem ua tau zoo rau kev pab lub neej ntawm cov nkoj. Txij li thaum ships khiav lag luam nyob rau hauv lub marine ib puag ncig rau ib ntev lub sij hawm, lub corrosiveness ntawm seawater poses siab yuav tsum tau rau corrosion kuj ntawm cov ntaub ntawv hull. ASTM A131 shipbuilding steel daim hlau tuaj yeem tiv taus dej hiav txwv zoo dua.
