American Standard ASTM A252 yog cov yeeb nkab piling khoom tus qauv uas tau siv dav hauv kev tsim kho thiab kev tsim vaj tsev. A252 specification suav nrog peb qib (1, 2, thiab 3), Qib 3 yeeb nkab piling khoom yog qhov kev xaiv tshaj plaws.

ASTM A252 cov ntsiab lus

ASTM A252 yog tus qauv specification rau welded thiab seamless steel yeeb nkab pawg. Nws npog lub nominal phab ntsa tuab ntawm lub tog raj kheej zoo steel yeeb nkab, cov yeeb nkab tsis suav nrog. Cov kav dej puag ncig no yog siv rau lub hom phiaj piling, ua si ua lub luag haujlwm tas li ntawm kev thauj khoom nqa thiab nqa lub siab. Tsis tas li ntawd, ua raws li lub plhaub tank kom sau nrog cov pob zeb ua ke ntawm qhov pom ntawm qhov project.

Cov qauv no tau hais txog qhov tseem ceeb hauv nti-phaus (tseem tuaj yeem txhais rau SI units), uas muab cov ntaub ntawv siv A252 yeeb nkab rau engineer lossis tus tsim qauv, rau lub hauv paus muaj zog ntawm kev tsim kho.

Tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm ASTM A252 yeeb nkab

Tus qauv muaj qhov txwv rau lub caij P (phosphorous) siab tshaj plaws 0.050%, vim P yuav ua rau cov hlau tsis muaj zog, thiab qhov tseem ceeb tshaj plaws yog tsis zoo rau kev ua haujlwm vuam. ASTM A252 tus qauv specifications tsuas yog txhais cov ntsiab lus ntawm phosphorous, lwm yam khoom raws li cov khoom siv carbon steel.

Mechanical Properties ntawm A252 yeeb nkab

Ntev ntev

Cov qauv siv rau kev ua ASTM A252 yeeb nkab

• ASTM A370 txoj kev tshuaj xyuas thiab cov ntsiab lus rau kev ntsuas cov khoom siv hlau.
• ASTM A751: Tshuaj ntsuam xyuas cov txheej txheem.
• ASTM A941: Terminology rau carbon, alloy thiab stainless hlau.
• E29 xyaum siv cov lej tseem ceeb hauv kev xeem kom txiav txim siab ua raws li qhov tshwj xeeb.

ASTM A252 pawg yeeb nkab cov khoom siv thiab kev tsim khoom

Xav txog ntawm cov khoom tsim, ASTM A252 yeeb nkab pawg tuaj yeem ua los ntawm cov txheej txheem seamless lossis welded.

Seamless yeeb nkab pawg

Seamless yeeb nkab pawg hu ua kub dov los yog txias kos thiab thermal nthuav seamless yeeb nkab.

Welded yeeb nkab pawg

Welded yeeb nkab pawg suav nrog ERW (hluav taws xob tsis kam welded), flash welded, fusion welded lossis sub-merged welded SSAW lossis LSAW. Longitudinal los yog helical kauv welded.

Raw khoom ua txheej txheem

Cov khoom siv raw hlau thiab hlau tuaj yeem ua los ntawm cov txheej txheem ntawm Open-hearth, Basic-oxygen, Hluav taws xob-kub.

Cov ntaub ntawv dab tsi yuav xav tau ua ntej yuav A252 yeeb nkab pawg

Ua ntej yuav cov yeeb nkab hauv qab ASTM A252 specification, cov ntaub ntawv hauv qab no yuav tsum tau:
a. Qhov ntau hauv ko taw, ' meter ', lossis tus naj npawb ntawm qhov ntev
b. Khoom npe nyob rau hauv steel yeeb nkab pawg
c. Kev tsim khoom hauv seamless lossis welded (ERW, EFW, LSAW, SSAW)
d. Qib (Muaj peb theem ntawm ASTM A252 Qib 3, 2, thiab 1)
e. Loj (OD thiab nominal phab ntsa thickness, lub sij hawm hauv ASME B36.10)
f. Length nyob rau hauv SGL, DGL los yog taag ntev.
g. Ends hom beveled los yog dawb xaus
h. Kev soj ntsuam ntsig txog thiab shipping cim

Kev them nyiaj tsis raug

Feem ntau cov imperfections saum npoo uas siab tshaj 25% yog hu ua qhov tsis xws luag, thiab rau qhov tsis xws luag uas tsis pub tshaj 22.5% ntawm nominal phab ntsa hauv qhov tob yuav raug kho los ntawm vuam. Ua ntej ua pob tw vuam rau ob pawg yeeb nkab, cov teeb meem no yuav tsum raug tshem tawm tag nrho.

A252 steel yeeb nkab pawg muaj peb qib

Raws li lub zog tensile thiab lub zog tawm los ASTM A252 tau muab faib ua peb pawg / qib:
a. ASTM A252 Qib 1
b. ASTM A252 Qib 2
c. ASTM A252 Qib 3

ASTM A252 Qib 3: Feem ntau siv cov khoom siv yeeb nkab

Hauv peb qib ntawm tus qauv no, ASTM A252 Qib 3 yeeb nkab piling yog feem ntau siv thiab siv hauv kev ua haujlwm piling. Vim tias nws muaj lub zog tensile siab dua (455 Mpa lossis 66, 000 psi) thiab tawm lub zog (310 Mpa lossis 45, 000 psi).

Kev Ntsuas Cov Lus Qhia rau A252 steel yeeb nkab piling hauv seamless thiab welded

Nws suav nrog:

Cov ntaub ntawv tsom xam

Kev Ntsuas Kub: Kev txwv rau cov ntsiab lus P, thiab cov txiaj ntsig kub yuav tsum tau tshaj tawm hauv MTC rau cov neeg siv khoom.
Kev tshuaj xyuas khoom: Kev xeem zaus yuav tsum tau txiav txim siab los ntawm cov yeeb nkab txoj kab uas hla, qhov twg, nyob rau hauv 14 nti 2 kuaj ib 200 daim, 14 mus rau 36 nti 2 kuaj ib 100 daim, saum 36 nti yog 2 ib 3000 ft.
Tensile xav tau: Cov nqi yuav tsum ua raws li lub zog tensile saum toj no thiab lub zog tawm los. Nws yuav tsum raug sau tseg tias yog tias tau txais qhov tsis paub meej qhov taw qhia, tom qab ntawd txhawm rau ntsuas qhov muaj zog ntawm lub zog sib haum mus rau qhov kev ua haujlwm ruaj khov ntawm {{0}}.2% ntawm qhov ntev gage ntawm cov qauv kuaj, lossis kuaj tag nrho txuas ntxiv ntawm 0.5% ntawm qhov ntev gage nyob rau hauv load.

Qhov hnyav thiab qhov ntev kam rau ua

Pipe pawg hnyav rau ib units(Feet, meter lossis ntev)
kam rau ua: A252 yeeb nkab pawg qhov hnyav yuav tsum nyob rau hauv +15% lossis -5% ntawm qhov ntsuas qhov ntsuas. OD tolerances ntawm +/-1%, phab ntsa thickness +/- 12%.
Ntev: Raws li tau teev tseg SRL, DRL, lossis qhov ntev 20 ft lossis 40 ft thiab kho.

Txawv tshaj lwm cov kav dej

Hydrostatic xeemtsis tau teev nyob rau hauv ASTM A252 yeeb nkab specification, raws li ib txwm piling yeeb nkab yog sau nrog cement thiab pob zeb thiab tsim, tsis yog rau cov kua kis tau tus mob, yog li hydrotest tsis tas yuav tsum tau.

Kev sim sib txawv rau seamless thiab welded yeeb nkab pawg

Seamless, welded, (Longitudinal lossis helical welded) txoj kev xeem sib txawv.Txheeb xyuas ASTM A252 yeeb nkab txheem specification kom paub meej ntxiv. Tab sis tag nrho cov hom no raug kuaj hauv chav tsev kub.

Pipe piling Prospective thiab kev siv

Niaj hnub no cov yeeb nkab piling yog tsim los rau ib qho kev taw qhia nrog kev sib sib zog nqus nrug thiab loj diameters siv, vim hais tias kev tsim kho, vaj tse, txuas hniav tam sim no tau nce siab dua super. Hauv Tebchaws Meskas lossis Nyiv cov yeeb nkab steel ntev tau mus txog 100 meter, txoj kab uas hla mus txog 2500 hli. Thiab nyob rau hauv Suav teb ntau dua.

Kev siv yeeb nkab piling

Lawv muaj kev txawj ntse los tswj cov khoom tsim nyog tau xa mus rau cov neeg siv khoom uas yuav ua kom muaj txiaj ntsig zoo rau lawv. Cov yeeb nkab steel yog muab los ntawm lawv yog ASTM A252 yeeb nkab uas muaj cov qauv cylindrical uas nqa cov khoom thauj thiab yog qhov tsim nyog rau ntau daim ntawv thov xws li

• Tsev
• Khaws cov phab ntsa
• Cov qauv sib txawv uas xav tau lub hauv paus tawv

Qhov no ua kom cov qauv yog cov khoom ruaj khov, vam khom nrog cov khoom zoo tshaj plaws uas yuav lav qhov toughness uas ua tau raws li cov kev cai thoob ntiaj teb.
