A500 steel siv rau dab tsi?
- Kev them nyiaj yug lub tsev: ASTM A500 cov kav dej tau siv dav hauv kev txhawb nqa thiab thauj khoom -cov kabmob rau cov tsev siab - nce siab, ntev - txuas txuas, thiab cov nroj tsuag loj. Lawv muab kev txhawb nqa zoo, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb.
- Pipeline Engineering: Vim lawv lub zog siab, tiv thaiv corrosion, thiab kev ua tau zoo ntawm seismic, cov kav dej no kuj tau siv dav hauv cov kav dej engineering. Lawv tuaj yeem ua cov khoom siv rau dej, roj, thiab cov kav dej, tsim nyog rau kev tsim kho hauv nroog, cov kav dej, thiab lwm yam kev siv.
- Txoj Kev thiab Tunnel Engineering: Hauv txoj kev thiab qhov av engineering, ASTM A500 cov kav dej yog qhov kev xaiv zoo tshaj plaws rau kev txhawb nqa txoj hauv kev thiab kev txhawb nqa qhov. Lawv muab kev txhim khu kev qha- cov kabmob muaj peev xwm, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm txoj kev thiab qhov.
- Lwm Daim Ntawv Thov: Dhau li ntawm cov ntawv sau tseg saum toj no, cov kav dej no kuj tau siv dav hauv kev ua liaj ua teb irrigation systems, aquaculture chaw, kev txhawb nqa fais fab, thiab lwm yam. Lawv ua tau zoo heev hauv ntau qhov chaw thiab kev siv, ua tau raws li cov kev xav tau sib txawv.

ASTM A500 VS ASTM A252
| Yam ntxwv | ASTM A500 1 | ASTM A252, ASTM A252 |
|---|---|---|
| Kev siv thawj zaug | Cov khoom siv xws li kev tsim cov ncej, txuas hniav, thiab kev tsim kho dav dav. | Piling thiab yeeb nkab piling daim ntaub ntawv, feem ntau yog rau cov hauv paus sib sib zog nqus thiab marine lug. |
| Yam khoom | Ua nyob rau hauv ob qho tib si welded thiab seamless daim ntawv, siv carbon steel. | Tshwj xeeb rau cov yeeb nkab steel, feem ntau ua los ntawm vuam. |
| Cov duab | Muaj nyob rau hauv square, rectangular, thiab round shapes. | Feem ntau puag ncig nyob rau hauv cov duab, raws li nws yog npaj rau piling lub hom phiaj. |
| Lub zog thiab Qib | Muaj nyob rau hauv Qib B thiab C (nrog cov kev xav tau tshwj xeeb thiab lub zog tensile). | Qib nyob rau hauv Chav Kawm Muaj Zog (Yield Strength): Chav Kawm 1 (30 ksi), Chav Kawm 2 (35 ksi), Chav Kawm 3 (45 ksi), thiab Chav Kawm 4 (50 ksi). |
