Qhov txawv ntawm Astm A53 thiab A252 yog dab tsi?

ASTM A252 yeeb nkab yog dab tsi?

ASTM A252 yog ib qho kev tso cai tshwj xeeb tsim los ntawm American Society for Testing and Materials (ASTM), tshwj xeeb rau cov kav hlau siv hauv pawg tsav tsheb thiab kev sib sib zog nqus cov ntawv thov. Cov txheej txheem no nruj me ntsis hais txog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev ntev thiab kev sim cov yeeb nkab steel, ua kom lawv cov qauv zoo heev, ua haujlwm ntev thiab muaj peev xwm thauj khoom. Nws yog qhov kev xaiv zoo tshaj plaws rau lub hauv paus tej yaam num xws li Choj, cov tsev siab siab thiab cov chaw nres nkoj.

Astm A252 Pipe Dimensionsqhov ntev thiab specifications

ASTM A252 cov kav dej tau muab faib ua peb qib raws li qhov yuav tsum tau muaj zog: GR 1, GR 2, thiab GR 3, cov qib GR 3 muaj lub zog siab tshaj plaws. Nws qhov loj me yog hloov tau thiab tuaj yeem ua tau raws li kev xav tau ntawm engineering

Sab nraud txoj kab uas hla (OD): Los ntawm 6 ntiv mus rau 60 ntiv tes, thiab txawm tias qhov ntau thiab tsawg tuaj yeem tsim tau.

Phab ntsa tuab (WT): Feem ntau ntawm 0.188 nti thiab 0.500 nti, thiab tuaj yeem hloov kho raws li qhov yuav tsum tau ua ntawm compressive thiab khoov tsis kam.

Ntev: Tus qauv ntev yog 20 ko taw lossis 40 ko taw. Customized ntau lawm kuj txhawb raws li qhov yuav tsum tau ua.

Qhov ntau ntawm qhov ntau thiab tsawg no ua kom cov engineers tuaj yeem xaiv tus nqi zoo tshaj plaws rau cov haujlwm tshwj xeeb.

ASTM A252 yeeb nkab yog siv rau ntau yam kev siv, suav nrog:

1. Piling: Cov kav dej no feem ntau yog siv los ua pawg hauv av hauv kev tsim kho kom muaj kev ruaj ntseg thiab kev txhawb nqa rau cov qauv.
2. Txuas hniav: Lub zog thiab kav ntev ntawm ASTM A252 yeeb nkab ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim choj, qhov chaw uas nws tuaj yeem tiv taus cov khoom hnyav thiab ib puag ncig.
3. Marine Structures: Qhov kev tiv thaiv corrosion ntawm cov kav dej no tso cai rau lawv siv rau hauv marine daim ntaub ntawv xws li docks thiab piers.
4. Roj thiab Roj: Vim nws txoj kev tsim kho muaj zog, ASTM A252 yeeb nkab kuj tseem siv rau hauv kev lag luam roj thiab roj los thauj cov kua thiab roj.

Hauv cov ntsiab lus

Cias muab, ASTM A252 yeeb nkab yog ib qho tseem ceeb ntawm cov khoom siv rau ntau yam kev siv, xa kev ntseeg tau thiab lub zog. Lub Hoobkas no hauv Cangzhou, Hebei Xeev, yog lub chaw tsim khoom ntawm cov yeeb nkab no, ua kom nws cov khoom ua tau raws li cov qauv zoo tshaj plaws. Nrog rau kev cog lus rau kev ua tau zoo thiab tsom mus rau kev tsim kho tshiab, lub tuam txhab tseem ua lub luag haujlwm tseem ceeb hauv kev tsim kho thiab kev tsim kho vaj tse. Txawm hais tias koj tau koom nrog hauv qhov kev tsim kho loj lossis xav tau cov kav dej txhim khu kev qha, ASTM A252 yeeb nkab yog qhov kev xaiv zoo rau koj cov kev xav tau.
