Tau txais cov neeg siv khoom txaus siab yog peb lub tuam txhab lub hom phiaj rau qhov zoo.Peb yuav ua kom zoo los tsim cov kev daws teeb meem tshiab thiab zoo tshaj plaws, ua kom tiav koj cov kev qhia tshwj xeeb thiab muab kev pabcuam ua ntej muag, muag thiab tom qab muag rau koj.ASTM A519 4130 Cov Khoom Siv Hluav Taws Xob Seamless Steel Tube, Tag nrho cov tshuab tuaj txawv teb chaws zoo tswj thiab lav lub machining precision rau cov khoom muag.Tsis tas li ntawd, peb tam sim no muaj ib pab pawg neeg tswj hwm cov neeg ua haujlwm zoo thiab cov kws tshaj lij, uas ua rau cov khoom zoo thiab muaj peev xwm los tsim cov khoom tshiab los nthuav peb lub lag luam hauv tsev thiab txawv teb chaws.Peb ua tsaug cia siab tias cov neeg siv khoom tuaj rau kev lag luam tawg paj rau peb ob leeg.
Muaj ntau lub sijhawm rau cov kav dej no thaum lawv tswj ntau theem ntawm kev kub ntxhov.Feem ntau muaj sch 80, 100, 120, 140 thiab 160 uas muaj phab ntsa hnyav.Cov phab ntsa tuab tuab seamless yeeb nkab tuaj yeem ua tau ob npaug ntxiv zog thiab txhais tau tias yog XXS lossis XXS.Cov khoom siv tuaj yeem sib txawv vim muaj cov qib sib txawv ntawm cov pa roj carbon steel uas siv los ua cov phab ntsa tuab tuab carbon steel yeeb nkab hom.Lub ntim siab, siab ntws, siab siab tshuab zoo li cov roj thiab roj xa mus, cov kab dej, thiab lub tshuab fais fab cua txias txhua yam siv ntau hom,
Thick-walled seamless steel kav yog siv rau hauv kev txuag dej, petrochemical, tshuaj, hluav taws xob fais fab, kev ua liaj ua teb, kev tsim kho hauv nroog thiab lwm yam lag luam.Rau kev thauj mus los ua kua: kev xa dej thiab kev tso dej.Gas kev thauj mus los: natural gas, steam, liquefied petroleum gas.Kev siv cov qauv: siv los ua cov kav dej txuas txuas;docks, txoj kev, cov tsev thiab lwm yam qauv.
Tus yuam sij rau qhov zoo ntawm tuab-walled steel kav yuav tsum yog thickness uniformity.Kev tswj tsis tau ntawm phab ntsa tuab ntawm cov kav hlau tuab tuab ncaj qha cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm cov kav hlau, cov kav hlau tuab tuab, thiab cov kav hlau loj loj seamless steel kav.Nws feem ntau yog siv rau ntau yam kev ua thiab tuab-walled qhov chaw ua.,, cov phab ntsa tuab ntawm cov yeeb nkab steel yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom tom qab ua tiav, cov phab ntsa tuab ntawm cov yeeb nkab steel tsis raug tswj, thiab tag nrho cov hlau zoo tsis nruj.
Thick-walled steel kav xa mus rau cov kav hlau uas muaj txoj kab uas hla mus rau phab ntsa thickness piv tsawg dua 20. Feem ntau yog siv rau roj av geological laum kav, petrochemical cracking kav, boiler kav, bearing kav thiab high-precision structural kav rau tsheb, tsheb laij teb thiab kev dav hlau.Qhov zoo ntawm tuab-walled seamless steel kav yog nyob ntawm qhov uniformity ntawm phab ntsa thickness.
Round tube billet → cua sov → tho → peb-yob hla dov, nruam dov los yog extrusion → stripping → sizing (los yog txo txoj kab uas hla) → txias → straightening → hydraulic test (los yog flaw detection) → marking → warehousing.
Cov khoom siv ntawm cov kav hlau hnyav hnyav yog qhov ntsuas tseem ceeb los xyuas kom meej qhov kev siv kawg (cov khoom siv cuab yeej cuab tam) ntawm qhov hnyav wallthickness steel kav steel kav, thiab nws nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov yeeb nkab steel.Yog li ntawd, raws li qhov kev thov sib txawv, cov khoom siv ntawm cov khoom hnyav wallthickness steel kav tau qhia tshwj xeeb los ntawm cov yam ntxwv ntawm tensile lub zog, qhov taw tes tawm, thiab elongation.
1. Lub zog tensile
Hauv cov txheej txheem tensile, qhov siab tshaj plaws quab yuam (Fb) uas tus qauv dais thaum nws tawg yog qhov kev ntxhov siab (σ) tau los ntawm qhov chaw hla ntu ntu (Yog li) ntawm tus qauv, uas yog hu ua lub zog tensile (σb), thiab Chav tsev yog N / mm2 (MPa).Nws sawv cev lub peev xwm siab tshaj plaws ntawm cov khoom siv hlau los tiv thaiv kev puas tsuaj nyob rau hauv tensile quab yuam.
2. Yield point
Rau cov khoom siv hlau uas muaj qhov tshwm sim tshwm sim, qhov kev ntxhov siab ntawm cov qauv tuaj yeem txuas ntxiv mus ntev yam tsis muaj kev nce hauv lub zog thaum lub sij hawm ncab (tseem nyob twj ywm) yog hu ua qhov taw tes tawm.Yog tias lub zog poob qis, cov ntsiab lus sab saud thiab qis dua yuav tsum tau paub qhov txawv.Chav tsev ntawm qhov taw tes tawm yog N / mm2 (MPa).
3. Elongation tom qab tawg
Hauv kev sim tensile, qhov feem pua ntawm qhov ntev ntawm qhov ntsuas qhov ntev tau nce tom qab tus qauv tawg mus rau qhov ntsuas qhov ntev yog hu ua elongation.Qhia los ntawm σ, chav tsev yog %.
Tau txais cov neeg siv khoom txaus siab yog peb lub tuam txhab lub hom phiaj rau qhov zoo.Peb tab tom yuav ua kom zoo los tsim cov kev daws teeb meem tshiab thiab zoo tshaj plaws, ua kom tiav koj cov lus qhia tshwj xeeb thiab muab koj cov kev muag khoom ua ntej, muag thiab tom qab muag kev pabcuam rau Cov Lag Luam wholesaleASTM A519 4130 Cov Khoom Siv Hluav Taws Xob Seamless Steel Tube, Tsuas yog ua kom tiav cov khoom zoo lossis kev pabcuam kom txaus siab rau cov neeg siv khoom xav tau, tag nrho peb cov khoom tau raug tshuaj xyuas nruj me ntsis ua ntej xa khoom.
Lag luam wholesale Tuam Tshoj Yeeb Nkab thiab Tube, Tag nrho cov tshuab tuaj txawv teb chaws zoo tswj thiab lav lub machining precision rau cov khoom muag.Tsis tas li ntawd, peb tam sim no muaj ib pab pawg neeg tswj hwm cov neeg ua haujlwm zoo thiab cov kws tshaj lij, uas ua rau cov khoom zoo thiab muaj peev xwm los tsim cov khoom tshiab los nthuav peb lub lag luam hauv tsev thiab txawv teb chaws.Peb ua tsaug cia siab tias cov neeg siv khoom tuaj rau kev lag luam tawg paj rau peb ob leeg.
