A516 Gr70 steel phajPuas yog cov khoom siv feem ntau hauv cov hlab ntsha tsim tawm, muaj kev cuam tshuam zoo heev, thiab muaj peev xwm tiv thaiv nruab nrab}- kub siab. Xaiv cov ntawv tsim nyog A516 Gr70 grit0 steel hlau yuav tsum muaj txoj hauv kev ua kom zoo nkauj kom ua raws li cov qauv kev lag luam thiab cov qauv kev lag luam.
Kauj ruam 1: Hais kom cov tuab tuab li ntawm qhov ntsuas qhov ntsuas siab
Lub thickness ntawm A516 Gr70 steel phaj tau txiav txim siab ncaj qha los ntawm qhov siab tshaj plaws ua haujlwm ntawm lub nkoj siab. Lub phaj yuav tsum tau tiv thaiv sab hauv thiab sab nraud tsis muaj deformation lossis tsis ua tiav.
A516 Gr70 thickness xaiv
Piv Txwv: Thickness rau 10MPA Tshuaj Cia Tank
Xav tias tsim cov tshuaj txiav tav rov qab nrog cov kab hauv qab no:
- MAX MAX MAX SIAB SIAB (P)=10 mpa mpa
- Sab hauv lub taub (d)=2000 hli
- Ua haujlwm kub=250℃(pub muaj kev ntxhov siab s rau A516 Gr70 ntawm qhov kub no {}} mpa mpa mpa)
- Weld Hom =}-}}}}}}}}}}}}}}}} {= 1.0)
Hloov pauv tsis rau hauv cov qauv:
- Thickness (t) {{{{= (p × d) / (2 × d × e- 0.2 × p)
- t = (10 × 2000) / (2 × 185 × 1.0 - 0.2 × 10)
- t = 20000 / (370 - 2)
- t=20000 / 368 ≈ 54.35mm
Txawm li cas los xij, tus nqi no sawv daws tsuas yog yuav tsum thickness. Ntxiv cov nyiaj pub ntxiv yuav tsum tau ntxiv thaum xaiv qhov tseeb:
Corrosion Allowance (feem ntau 1 {- 3mm rau cov xov xwm tsis yog-corrosive, 3-5mm rau cov khoom siv tsis muaj zog)
Kev Tso Cai Siv Khoom Siv (piv txwv li, 1-2 hli rau kev txiav, dov, machining, thiab lwm yam)
Kauj ruam 2: Xaiv cov khoom ntawv pov thawj raws li kev sib raug zoo
Cov hom kua lossis roj khaws cia lossis thauj hauv lub nkoj siab txiav txim siab cov ntawv pov thawj xav tau rau A516 Gr70 Steel phaj. Txawv tawm txawv cov lus qhia tshwj xeeb cov cai ntawm cov khoom siv.
Cov ntawv pov thawj tseem ceeb los xav txog:
- ASME BPV daim ntawv pov thawj: Yuav tsum tau rau cov nkoj siab hauv kev lag luam feem ntau. A516 Gr70 daim hlau yuav tsum ua raws li ASME SAMEA66 / SA516M cov qauv, uas qhia meej cov tshuaj muaj kuab lom thiab cov khoom siv neeg kho mob.
- Tsawg - kub} Cov ntawv pov thawj kub (LT qib kev ua haujlwm yog tsawg dua lossis sib npaug ntawm -10℃yuav tsum tau xaiv.
Kauj ruam 3: Piv txog A516 GR70 nrog A515 GR70 kom paub meej tias cov khoom siv haum
A515 Gr70 yog lwm cov roj carbon steel rau cov hlab roj siab, tab sis nws txawv ntawm A516 Gr70 hauv cov yam ntxwv ua tau zoo.

Kauj ruam 4: Paub meej ntxiv cov kev cai ntxiv
- Hlau phaj loj me:Nco ntsoov tias qhov dav thiab ntev ntawm A516 Gr70 cov paib hlau phim lub nkoj tsim los txo Weld leeg suav. Rau cov loj - riam tso tsheb hlau luam (ID> 3M), phiaj hlav ntau dua los yog sib npaug rau kev txo kom muaj nuj nqis.
