Ob leeg ASTM A516 Gr.70 thiab ASTM A105 yog cov hlau siv rau kev siv sib txawv, rau lub nkoj siab thiab flange fabrication feem. Tus nqi sib txawv ntawm ob tuaj yeem tshwm sim los ntawm ntau yam:
1. Khoom siv tus nqi sib txawv:
ASTM A516 Gr.70 feem ntau yog siv los tsim cov hlab ntsha siab, thiab nws cov ntaub ntawv yuav tsum ua kom tau raws li cov kev xav tau siab dua, suav nrog lub zog tensile, lub zog tawm los, cuam tshuam toughness, thiab lwm yam.ASTM A105 1yog siv los tsim cov flanges, uas feem ntau muaj cov khoom siv qis dua. Yog li ntawd, tus nqi tsim khoom ntawm ASTM A516 Gr.70 yuav siab dua.
2. Qhov sib txawv ntawm cov khoom siv:
ASTM A516 Gr.70 cov ntaub ntawv feem ntau xav tau kev ua haujlwm engineering thiab tuav kom tau raws li lawv cov kev xav tau hauv kev kub siab thiab kub kub. Qhov no tej zaum yuav xav tau ntau cov txheej txheem thiab cov khoom siv tswj, ntxiv cov nqi ntxiv.
3. Kev lag luam xav tau thiab khoom siv:
Kev lag luam xav tau thiab cov khoom siv sib txawv kuj tseem yuav cuam tshuam tus nqi. Yog tias qhov kev thov rau ASTM A516 Gr.70 siab thiab cov khoom siv me me, ces tus nqi yuav nce mus. Ntawm qhov tsis sib xws, yog tias cov khoom ntawm ASTM A105 txaus thiab qhov kev thov tsawg dua, tus nqi yuav qis dua.
4. Manufacturing complexity:
Flangesfeem ntau yooj yim rau kev tsim dua li cov hlab ntsha siab vim lawv feem ntau yog cov duab yooj yim dua. ASTM A516 Gr.70 cov khoom siv yuav xav tau kev ua haujlwm engineering ntxiv kom tau raws li qhov xav tau ntawm cov hlab ntsha ntawm ntau cov duab thiab ntau thiab tsawg.
Hauv cov ntsiab lus, tus nqi sib txawv ntawm ASTM A516 Gr.70 thiab ASTM A105 tuaj yeem raug ntaus nqi rau ntau yam xws li cov khoom siv, kev xav tau ntawm kev lag luam, muaj, thiab kev tsim khoom nyuaj. Thaum yuav khoom, cov khoom no yuav tsum tau ntsuas raws li cov kev xav tau tshwj xeeb thiab cov ntawv thov los xaiv cov khoom siv thiab xav txog nws tus nqi.
