Cov qauv siv thiab kev siv:
- API 5LX70 Roj thiab roj xa cov yeeb nkab: Cov yeeb nkab steel no ua raws li API 5L specification thiab feem ntau yog siv hauv kev lag luam roj thiab roj rau kev thauj mus los hauv kev kub siab, kub kub ib puag ncig.
- A106: Cov yeeb nkab steel no ua raws li ASTM A106 specification thiab feem ntau yog siv rau kev thauj mus los ntawm cov kua xws li dej, roj, thiab cov nkev roj, nrog rau kev siv xws li boilers, tshav kub exchangers, boiler superheaters, thiab cov khoom siv kub.
Tshuaj muaj pes tsawg leeg thiab lub zog:
- API 5LX70 welded kab yeeb nkab: Muaj cov ntsiab lus qis carbon thiab manganese kom ntseeg tau zoo toughness thiab weldability, thaum muab siab yield thiab tensile zog ntawm 485MPa thiab 570MPa feem.
- A106: Muaj cov ntsiab lus carbon thiab manganese ntau dua, nws lub zog tensile yog 330MPa, 415MPa thiab 485MPa nyob ntawm qib (A106A, B, C), thiab nws yog siv rau kev thauj mus los ntawm cov dej hauv chav tsev kub.
Kev tsim khoom:
API 5LX70 Roj thiab roj yeeb nkab kab: Cov txheej txheem tsim muaj xws li steelmaking, dov, tho thiab kho cua sov, yuav tsum tau tswj nruj ntawm cov khoom zoo thiab kev ua haujlwm.
A106: Nrog rau ob qho tib si txias txias thiab kub dov txheej txheem, cov khoom yog dov thiab txias hauv kev tswj kom tau raws li cov khoom siv tshwj xeeb.
Corrosion resistance thiab daim ntawv thov scenarios:
- API 5L X70 Carbon Steel Kab Yeeb Nkab: Vim nws cov kev ua haujlwm siab thiab kev ntsuas tshwj xeeb los tiv thaiv corrosion (xws li cov txheej sab hauv thiab sab nraud, alloying), nws yog tshwj xeeb tshaj yog tsim rau siv nyob rau hauv ib puag ncig corrosive thiab high-temperature thiab high-pressure conveying dej num.
- A106: Feem ntau muaj kev tiv thaiv corrosion zoo, tab sis yuav xav tau kev tiv thaiv corrosion ntxiv hauv qhov chaw huab cua.
