Yuav Ua Li Cas Xaiv Ntawm SA516 Gr.60 thiab Gr.70 rau Koj Lub Tank LPG
Xaiv qhov raug lub nkoj siab steel phaj rau LPG (liquefied petroleum gas) cia tank yog qhov kev txiav txim siab tseem ceeb. Nws cuam tshuam ncaj qhakev nyab xeeb, kev tswj hwm kev tswj hwm, cov nqi tsim khoom, thiab lub tank lub neej ua haujlwm.
Ob ntawm cov khoom siv feem ntau tau teev tseg raws li ASME Boiler thiab Pressure Vessel Code yogTIAB SA 516 Gr.60thiabTIAB SA 516 Gr.70. Txawm hais tias ob qho tib si yog cov pa roj carbon zoo heev rau nruab nrab thiab qis dua - kev pabcuam kub, lawv tsis hloov pauv.
Cov lus qhia no rhuav tshem qhov sib txawv tseem ceeb - cov khoom siv kho tshuab, cuam tshuam rau tus nqi, tsim cov kev xav tau siab, thiab kev txiav txim siab vuam- los pab koj txiav txim siab xaiv rau koj qhov project LPG tank tom ntej.
Kev sib piv ceev: SA516 Gr.60 vs. SA516 Gr.70
| Parameter | TIAB SA 516 Gr.60 | TIAB SA 516 Gr.70 |
|---|---|---|
| Yam tsawg kawg Tensile Strength | 60 ksi (415 MPa) | 70 ksi (483 MPa)- 16% muaj zog dua |
| Yam tsawg kawg Yield Strength | 32 ksi (220 MPa) | 38 ksi (262 MPa)- 19% siab dua |
| Hom Kev Ua Haujlwm Siab | qis rau nruab nrab | Nruab nrab mus rau siab |
| Tus nqi kwv tij ib tuj | Lub hauv paus | Siab dua me ntsis (kwv yees . 5-8%) |
| Hom LPG Tank Hom | Me me hauv tsev tso tsheb hlau luam, bulk cia ntawm nruab nrab siab | Loj ASME-stamped tanks, thauj cov nkoj, siab - cov mos txwv tso tsheb hlau luam |
Tsim Siab thiab Tank Loj
TIAB SA 516 Gr.70
TIAB SA 516 Gr.70muaj tus nqi siab dua tso cai rau hauv ASME Code (Section VIII, Division 1). Qhov no txhais tau tias rau lubtib phab ntsa thickness, Gr.70 tank tuaj yeem tiv taus siab dua sab hauv. Conversely, rau covtib lub siab ntsuas, koj tuaj yeem siv lub phaj nyias nyias Gr.70, txo qhov hnyav tag nrho.
TIAB SA 516 Gr.60
TIAB SA 516 Gr.60yog tsim nyog rau qis dua - cov ntawv thov siab los yog loj dua, ntau lub tso tsheb hlau luam qhov chaw siab hauv nruab nrab thiab qhov hnyav txo qis yog qhov tseem ceeb.
Tswv yim piv txwv
Loj, mos txwv -style LPG cia lub nkoj ua haujlwm ntawm 250 psi yuav luag yuav tsum tau SA516 Gr.70 kom tau raws li cov cai- xav tau kev ntsuas kev ntxhov siab yam tsis muaj phab ntsa tuab. Rau ib tug me me, domestically rated tank ntawm 100 psi, Gr.60 tej zaum yuav zoo kawg nkaus txaus thiab ntau yig.
Tsawg-Temperature Toughness (LPG Service)
LPG khaws cia nyob rau hauv siab raws li ib tug kua, uas boils nyob ib ncig ntawm -43℃(-45℃F) atmospheric siab. Thaum lub tank ua haujlwm nyob rau hauv siab, lawv yuav tsum nyob twj ywmtawv thiab ductiletxawm nyob rau qhov kub thiab txias ambient los yog thaum lub sij hawm cia siab poob.
Ob leeg Gr.60 thiab Gr.70 yog tsim los rau nruab nrab thiab qis dua -kev pabcuam kub.Feem ntau, ob qib tuaj yeem ua tau raws li Charpy V-qhov ntsuas qhov ntsuas qhov ntsuas ntawm -40℃(-40℃F) thaum teev nrognormalized tshav kub kho.
Peb qhov kev pom zoo:Rau txhua lub tank LPG hauv cov huab cua txias (piv txwv li, Northern USA, Canada, Europe),ib txwm qhia normalized SA516 Gr.70. Lub zog siab dua ua ke nrog cov ntawv pov thawj qis- qhov kub thiab txias cuam tshuam ua rau muaj kev nyab xeeb ntxiv rau kev tiv thaiv kev puas tsuaj.
Weldability thiab Fabrication
Ob qib muaj qhov zoo tshaj plaws weldability vim lawv cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.30%) thiab qis carbon sib npaug (CE).
Tsis muaj qhov sib txawv loj:Koj tuaj yeem welding ob qho tib si Gr.60 thiab Gr.70 siv tus qauv qis- cov txheej txheem hydrogen (SMAW, GMAW, FCAW, SAW) nrog preheating feem ntau tsis tas yuav tsum tau rau cov phaj nyias (hauv qab 25mm) raws li lub khw muag khoom ib txwm muaj.
Thicker phaj:Rau cov seem tshaj 38 hli, ob qib yuav tau txais txiaj ntsig los ntawm qhov nruab nrab preheat (50-100 degree) thiab tom qab vuam kub kho (PWHT) raws li ASME xav tau.
Cov kab hauv qab:Fabrication nyuaj yog ze li qub. Koj qhov kev xaiv yuav tsis raug tsav los ntawm weldability.
Koj yuav tsum xaiv qib twg?
| Yog tias koj qhov project LPG tank xav tau ... | Pom zoo Qib |
|---|---|
| ASME Code stamp (feem ntau cov nkoj LPG ua lag luam) | TIAB SA 516 Gr.70(nyiam dua rau siab dua tso cai) |
| High design pressure (>200 psi) los yog txoj kab uas hla loj | TIAB SA 516 Gr.70(kom txo cov phab ntsa thickness) |
| Certified low-kub toughness mus rau -40 degree | Ob leeg, nrog Normalized(Gr.70 muaj zog dua) |
| Tus nqi pib tsawg tsawg, tsis tshua muaj siab, tsis yog -code tank | TIAB SA 516 Gr.60 |
| Thauj LPG tank (txoj kev / tsheb ciav hlau) - qhov hnyav yog qhov tseem ceeb | TIAB SA 516 Gr.70(lwm lub nkoj) |
| Txoj haujlwm hauv cheeb tsam nrog kev soj ntsuam nruj (xws li EU, North America) | SA516 Gr.70 nrog EN 10204 3.2 |

FAQ
01.Dab tsi yog qhov tsawg kawg nkaus tsim kub rau ASME SA516 Gr.70 siab nkoj steel phaj?
SA516 Gr.70 tshwj xeeb tsim raunruab nrab thiab qis dua -kev pabcuam kub. Tus txheej txheem tso cai rau kev sim cuam tshuam mus rau-40 ° F (-40 ° F)thaum cov khoom raug txiav txim nyob rau hauv lubnormalizedmob.
Rau LPG tso tsheb hlau luam thiab lwm lub nkoj siab ua haujlwm hauv huab cua txias, peb xav kom qhia meejnormalized SA516 Gr.70 nrog Charpy V- ntsuas qhov cuam tshuam ntawm -40 degree. Qhov no ua kom lub phaj tuav zoo heev toughness thiab tiv thaiv nkig tawg nyob rau hauv cia li kub poob los yog siab hloov. Rau cov ntawv thov hauv qab -40 degree, lwm yam qis- carbon lossis npib tsib xee-alloy steels yuav tsum tau.
02.Yog preheating yuav tsum tau thaum vuam SA516 Gr.70 steel phaj?
Yog lawm, SA516 Gr.70 muajzoo heev weldabilityvim nws cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.30%) thiab qis carbon sib npaug (CE). Rau cov phaj nyias nyias (feem ntauhauv qab 25mm / 1 nti), preheating yogtsis xav taunyob rau hauv lub khw tej yam kev mob thaum siv qis - hydrogen vuam txheej txheem (SMAW, GMAW, FCAW, SAW).
Txawm li cas los xij, raucov phaj tuab (tshaj 38mm), los yog thaum lub ambient kub yog tsawg (qis dua 5℃/ 41℃F), ib tug nruab nrab preheat ntawm50-100 ° F (120-210 ° F)raug pom zoo kom txo qis kev pheej hmoo ntawm hydrogen-induced cracking. Ib txwm ua raws li cov txheej txheem vuam tsim nyog (WPS) thiab ASME Code cov cai. Post-weld heat treatment (PWHT) tej zaum yuav xav tau rau cov ntu tuab lossis cov kev pabcuam tshwj xeeb.
03.Yog SA516 Gr.70 thiab A516 Gr.70 tib yam? Qhov txawv li cas?
Lawv yogyeej tseem zoo tib yamnyob rau hauv cov nqe lus ntawm tshuaj muaj pes tsawg leeg thiab mechanical zog. Qhov txawv yog purely nyob rau hauv lubnpe convention:
SIB 516hais txog covASMEspecification (Tshooj II, Ntu A) - siv rau cov hlab ntsha siab ua rau lubASME Boiler thiab Pressure Vessel Code.
A516hais txog covASTMspecification - tus qauv qub tsim los ntawm ASTM International.
Nyob rau hauv kev xyaum, feem ntau cov hlab ntsha siab manufacturers qhiaTIAB SA 516 Gr.70vim ASME Code yuav tsum muaj "SA" npe rau code-stamped nkoj. Txawm li cas los xij, cov khoom siv yog tib yam. Ntau tus neeg muag khoom (xws li Yuxin Steel) tsim cov phiaj xwm sib ntsibASME SA516 thiab ASTM A516xav tau ib txhij.
04.Koj puas muab EN 10204 Hom 3.2 ntawv pov thawj rau SA516 Gr.70 daim hlau? Tus nqi thiab lub sijhawm ua haujlwm yog dab tsi?
Yog, kiag li.Peb tuaj yeem muab tauEN 10204 Hom 3.2Kev soj ntsuam daim ntawv pov thawj rau SA516 Gr.70 daim hlau thaum thov.
