Qhov txawv ntawm Chav Kawm 1 thiab Chav Kawm 2 SA-387

SA-387 alloy steel daim hlauyog dav siv nyob rau hauvCov hlab ntsha siab, boilers, kub exchangers, thiab reactorsua haujlwm ntawm qhov kub siab.

Raws li tus kws tshaj lijsiab hlab ntsha steel phaj tsum, GNEE Steel feem ntau tau txais cov lus nug tseem ceeb los ntawm EPC cov neeg cog lus thiab cov khoom lag luam:

Qhov txawv ntawm Chav Kawm 1 thiab Chav Kawm 2 SA-387 yog dab tsi?

Qhov sib txawv tseem ceeb ntawm SA387 Class 1 thiab Class 2 steel phaj nyob hauv lawvmechanical zog, tshwj xeeb tshaj yog tensile thiab yield zog, nrog rau chav kawm 2 muab lub zog ntau dua (thiab qee zaum qis dua elongation) vim muaj peev xwm sib txawv ntawm kev kho cua sov lossis kev ua, thaum cov tshuaj muaj pes tsawg leeg tseem nyob ze rau cov qib zoo ib yam li Qib 11 lossis 22, ua rau Chav Kawm 2 tsim nyog rau siab dua - kev ntxhov siab, siab dua - qhov kub thiab txias.

Kab lus no muab cov lus piav qhia meej, siv tau los ntawm asiab nkoj thiab alloy steel kws tshaj lij kev pom, pab cov neeg yuav khoom xaiv qhov raug SA-387 chav kawm rau lawv cov ntawv thov thaum ua tau raws li ASME cov cai.

Thawj qhov sib txawv ntawmChav Kawm 1 thiab Chav Kawm 2 SA-387nyob hauv:

✅ Kev kho cua sov
✅ Mechanical zog xav tau
✅ Tsim muaj peev xwm siab thiab kub

Ntsiab Lus Txhais:

Chav Kawm 1→ Supplied nyob rau hauv lubRaws li -Rolled lossis Normalizedmob

Chav kawm 2→ Supplied nyob rau hauv lubNormalized thiab Tempered (N + T)mob

Qhov kev sib txawv no cuam tshuam rau lub zog, tawv, thiab qhov muaj txiaj ntsig kev ntxhov siab nyob rau hauv ASME cov lej tsim.

Siab tawm los thiab tensile zog

Zoo dua toughness thiab creep kuj

Txaus siab rau kev pabcuam tseem ceeb ntawm lub nkoj

Kev xaiv ntawm SA-387 Chav Kawm 1 thiab Chav Kawm 2 nyob ntawm koj cov khoom siv kev ua haujlwm thiab kev ua haujlwm tau zoo:

Thaum Yuav Siv SA-387 Chav Kawm 1:

Nruab nrab kub (tsawg dua los yog sib npaug rau 593 degree) thiab kev siv siab.

General -cov khoom siv hluav taws xob ua kom sov, qis- cov hlab ntsha, thiab cov kav dej.

Tus nqi -rhiab tej yaam num uas siab alloy ntsiab lus tsis tsim nyog.

 

Thaum Yuav Siv SA-387 Chav Kawm 2:

Siab - kub (txog 649 degree) thiab siab - cov khoom siv tseem ceeb.

Heavy- lub luag haujlwm lub raj plhaub cua sov hloov pauv, petrochemical reactors, thiab cov tshuab hluav taws xob.

Ib puag ncig ua rau corrosion lossis nkag mus, xws li cov pa roj ua kua qaub.

Ntawm GNEE, peb muabASTM A387-certified Class 1 thiab Class 2 steel phajua raws li cov kev xav tau ntawm cov khoom lag luam tsim khoom lag luam-tshwj xeeb tshaj yog rau cov tube plhaub kub exchangers, uas yog peb cov khoom tseem ceeb.

Peb SA-387 daim hlau muaj:
