A252 yeeb nkab yog categorized raws li cov qauv ntawm American Society for Testing and Materials. ASTM A252 yeeb nkab nta cov ntsiab lus phosphorus siab tshaj plaws ntawm 0.050%, uas tuaj yeem ua rau cov khoom me ntsis nkig thaum cov txheej txheem vuam.
Qib no feem ntau qhia txog qib phosphorus tso cai, thaum lwm yam tshuaj lom neeg ua raws li cov pa roj carbon monoxide-steel compositions. Cov kav dej no ua haujlwm raws li kev thauj khoom mus tas li- cov kabmob cov kabmob, ua rau kev tsim cov plhaub lossis cov pob zeb ua ke - puv pawg.
Cov kav dej hloov tau tau muab faib ua peb pawg- Qib 1, 2, thiab 3. Ntawm lawv, ASTM A252 Gr 3 Carbon Steel Pipe nthuav tawm lub zog siab tshaj plaws, muab lub zog tensile yam tsawg kawg nkaus ntawm 456 MPa thiab qhov tsawg kawg nkaus yield zog ntawm 310 MPa.
Cov pa roj carbon-steel variants yog dav siv nyob rau hauv fabrication assemblies, structural frameworks, tiv thaiv casings, piling project, txuas hniav, thiab micro-pile foundations.
ASTM A252 Yeeb Nkab Pile feem ntau yog siv rau hauv kev sib sib zog nqus hauv paus ua haujlwm, pab hloov cov khoom thauj los ntawm cov txheej txheem loj mus rau cov txheej hauv av. Cov kav dej no tuaj yeem muab rau nrog qhib- xaus lossis kaw- xaus kev teeb tsa thiab tuaj yeem nruab nrog lub kaus mom lossis ntim nrog pob zeb rau kev sib khi.
Hlau Yeeb Nkab Pile ASTM A252 yog tsim nyob rau hauv cov sij hawm xws li SCH 40, XS, 80, XXS, thiab 160. Txhawm rau txhim khu kev ruaj ntseg, cov pawg no tuaj yeem galvanized rau kev txhim kho kev puas tsuaj thiab corrosion. Standard mov lengths muaj xws li ib qho random, ob chav random, thiab uniform lengths.
Piping Cheebtsam hauv qib ASTM A252 yog tsim nyob rau hauv ob qho tib si seamless thiab welded ntau yam. ASTM A252 Welded Steel Yeeb Nkab yog tsim los ntawm kev tsim cov nplooj ntawv steel lossis strips thiab vuam lawv longitudinally, kauv, lossis ncaj.
Cov nqi no -cov kav dej zoo feem ntau yog xaiv rau qis-siab thiab nruab nrab- qhov kev pabcuam kub. Ntawm qhov tod tes, ASTM A252 Seamless Pipes yog tsim los ntawm cua sov steel billets thiab extruding lawv los ntawm kev tsim tuag kom ua tiav qhov ntev.
Seamless kav muab kwv yees li 20% ntau dua load-cov kabmob muaj peev xwm piv rau cov welded hom, txawm tias lawv tuaj nrog cov nqi ntau dua. Peb cov khoom yog tus nqi sib tw thoob plaws txhua qhov chaw faib khoom - xav tias dawb hu rau peb kom paub meej ntxiv.
