ASTM A333 / ASME SA333 yog tus qauv specification rau seamless thiab welded steel yeeb nkab rau daim ntawv thov nyob rau hauv tsis tshua muaj kub kev pab cuam thiab lwm yam kev siv uas yuav tsum tau notch toughness.
Dimensions thiab qhov ntau thiab tsawg program
Cov yeeb nkab tau ntsib ASME B36.10M nominal dimension standard. (NPS los yog sab nraud txoj kab uas hla thiab qhov nruab nrab thickness program naj npawb)
Lub caij no, qee qhov ntau thiab tsawg ntawm cov yeeb nkab yuav tsis muaj nyob rau hauv ASTM A333 tus qauv, vim tias cov phab ntsa hnyav dua muaj cov khoom tsis zoo. Yog tias tus neeg siv khoom muaj cov cai tshwj xeeb, cov lus qhia ntxiv hauv ASTM A333 yuav tsum ua raws.
Hom kev tsim khoom
Cov qauv muaj xws li welded (ERW) thiab seamless manufacturing hom. Cov khoom siv npog carbon thiab alloy steels.

Kev kho cua sov
Tag nrho cov seamless thiab welded steel yeeb nkab, tshwj tsis yog ASTM A333 Qib 8 thiab Qib 11, yuav tsum tau kho los tswj microstructure hauv kev xaiv raws li hauv qab no,
1.Normalized nyob rau hauv ib tug uniform kub tsis tsawg tshaj li 815℃[1500 ℉], thiab txias nyob rau hauv cov huab cua los yog nyob rau hauv lub txias chamber ntawm ib tug tswj cua kub qhov cub, los yog tom qab no tshav kub kev kho mob, ces tshav kub mus rau ib tug haum kub kom ua tiav.
2.Ntxiv rau qhov kev xaiv kev kho cua sov saum toj no, thiab nrog cov tuam txhab tsim khoom, nws yuav rov ua cov khoom siv rau qhov haum tempering.
Nyob rau hauv cov ntaub ntawv ntawm seamless steel yeeb nkab nyob rau hauv ASTM A333, reheat thiab tswj lub kub ua hauj lwm thiab kub xov ua hauj lwm kub mus rau ib tug tiav kub ntawm 845 mus rau 945℃[1550 mus rau 1750 ℉], thiab txias nyob rau hauv huab cua los yog nyob rau hauv ib tug tswj huab cua tiv thaiv los ntawm qhov pib kub ntawm ntau tshaj 845℃[1550 ℉] Rau ASTM A333 seamless steel yeeb nkab hauv Qib 1, Qib 6 thiab Qib 10, nws tuaj yeem raug kho los ntawm qhov kub tsis sib xws ntawm ntau dua 815℃[1500℉], tom qab ntawd quenched hauv cov kua thiab rov ua kom sov kom haum rau qhov kub thiab txias, hom kev kho cua sov no tuaj yeem hloov cov phiaj xwm dhau los kuj tau muab los ntawm ASTM}3 Grade ASTM A 3 / ASTM A 3 / ASTM 3 / AST 8 thiab Qib 11, kev kho cua sov yuav tsum ua tau raws li tus qauv specification.
Rau ASTM A333 Qib 1, Qib 6 thiab Qib 10 steel yeeb nkab, thiab nws tsis raug tso cai ntxiv cov tshuaj tsis tau teev tseg hauv qhov tshwj xeeb, tab sis nws raug tso cai ntxiv cov khoom rau steel deoxidation.
