2. Kauj Ruam -los ntawm - Cov txheej txheem tsim khoom
Kev tsim cov kav dej seamless steel yog cov txheej txheem kev ua haujlwm siab uas muaj ntau theem tseem ceeb - los ntawm kev xaiv cov khoom siv raw mus rau kev tshuaj xyuas tiav. Hauv qab no yog ib kauj ruam -los ntawm- kauj ruam qhia txog yuav ua li cas seamless kav yog tsim nyob rau hauvHuayang steel yeeb nkab.
| Theem | Txheej txheem piav qhia | Lub Hom Phiaj/Qhov tshwm sim |
|---|---|---|
| 1. Kev xaiv Billet | High -zoo round billets raug xaiv, feem ntau yog ua los ntawm carbon steel los yog hlau alloy. | Xyuas kom cov khoom zoo ib yam. |
| 2. Cua sov | Billets yog rhuab nyob rau hauv ib tug rotary hearth rauv ntawm ib ncig ntawm 1200 degree. | Softens lub billet rau tho. |
| 3. Kev tho | Lub rhuab billet yog pierced siv Mannesmann piercer los tsim lub plhaub hollow. | Tsim qhov pib qhov nyob rau hauv lub billet. |
| 4. Elongation thiab Rolling | Lub plhaub dhau los ntawm elongators lossis mandrel mills kom ua tiav cov phab ntsa tuab thiab txoj kab uas hla. | Tswj cov yeeb nkab qhov ntev thiab smoothness. |
| 5. Qhov loj me thiab txo qis | Cov kav dej yog dov mus ntxiv kom zoo dua qhov ntev thiab roundness. | Ua kom pom tseeb qhov tseeb. |
| 6. Kev kho cua sov | Cov kav dej tau normalizing lossis quenching thiab tempering. | Txhim kho txhua yam khoom thiab toughness. |
| 7. Ncaj thiab txiav | Cov kav dej yog straightened thiab txiav mus rau qhov ntev. | Npaj cov kav dej rau kev tshuaj xyuas thiab xa khoom. |
| 8. Tsis yog -Kev Ntsuas Kev Ua Phem (NDT) | Ultrasonic los yog eddy tam sim no kuaj yog ua. | Txheeb xyuas qhov tsis xws luag sab hauv lossis qhov chaw. |
| 9. Tiav & Kos npe | Cov kav dej yog beveled, pleev xim rau, thiab cim nrog specifications. | Ua kom traceability thiab tiv thaiv nto. |
CovMannesmann tho txoj kevtseem yog cov txheej txheem ntau tshaj plaws rau kev tsim cov kav dej seamless mus txog 24 inches inch. Rau loj diameters, lubplug zeblos yogstretch txo zebtxheej txheem yuav raug siv.
3. Kev kho cua sov thiab ua kom tiav
Tom qab dov, kev kho cua sov yog qhov tseem ceeb rau kev ua tiav qhov xav tau lub zog thiab ductility. Cov qib sib txawv xav tau kev kho cua sov tshwj xeeb:
| Qib | Kev kho cua sov | Yam khoom tshwm sim |
|---|---|---|
| ASTM A106 Gr.B | Li qub | Txhim kho toughness |
| ASTM A335 P11 | Quenched thiab Tempered | Siab creep kuj |
| API 5L X65 | Li qub | Txhim khu lub zog thiab weldability |
Surface finishing suav nrogtxhaj tshuaj blasting, kua roj vanish txheej, beveling, thiab kawg tiv thaiv kaus mom. Cov no tiv thaiv corrosion thiab mechanical puas thaum tuav thiab thauj.
NtawmHuayang steel yeeb nkab, tag nrho cov kav dejkuaj hydrostaticallyua ntej ua zaub mov xa tuaj, xyuas kom txhua tus ua tau raws li cov neeg siv khoom tshwj xeeb thiab cov qauv thoob ntiaj teb.
4. Dimensional Standards thiab Tolerances
Seamless kav yog tsim raws li thoob ntiaj teb cov qauv uas txhais tau lawvSab nraud txoj kab uas hla (OD), phab ntsa thickness, thiab ntev kam rau ua. Hauv qab no yog qee cov qauv ntsuas qhov sib txawv ua raws liHuayang steel yeeb nkab.
| Txuj | Daim ntawv thov | OD Ntau (mm) | Phab ntsa Thickness (mm) | Ntev Options |
|---|---|---|---|---|
| API 5L | Roj & Roj pipelines | 21.3–660 | 2.77–70 | 5.8m / 11.8m / R.L. |
| ASTM A106 / A53 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106) thiab ASTM A106 / A53 | Kev kub siab thiab kev siv tshuab | 21.3–610 | 2.11–65 | 6m / 12m / Kev cai |

Nco tseg:RL.=Random Ntev; CL .=Custom Length
Txhua tus qauv txhaisqhov tolerances, xws li ± 0.5% rau OD thiab ± 10% rau phab ntsa thickness. Cov kev tolerances no ua kom zoo ib yam thiab yooj yim compatibility nrog fittings thiab flanges thaum lub sij hawm installation.
5. Dimensional raug thiab kuaj
Precision nyob rau hauv phab ntsa thickness thiab txheej kab yog qhov tseem ceeb, tshwj xeeb tshaj yog rausiab -siab lossis siab - qhov kub thiab txias. Huayang txais yuavTsis siv neeg ultrasonic thickness gaugesthiablaser -raws li OD ntsuas tshuabkom tswj tau qhov tseeb.
Ntxiv nrog rau cov kev sim tshuab, cov hauv qab notsis yog -kev kuaj kev puas tsuaj (NDT)tau ua:
Kev kuaj ultrasonic (UT):Nthuav cov flaws sab hauv.
Eddy Current Testing (ECT):Txheeb xyuas cov kab nrib pleb.
Kev Ntsuas Hydrostatic:Txheeb xyuas qhov nruj nruj.
Magnetic Particle Test (MT):Tshawb xyuas qhov tsis sib xws.
Txhua yeeb nkab yog stamped nrog anws tus lej traceabilitytxuas mus rau tus xov tooj cua sov thiab daim ntawv pov thawj.
6. Dimensional Standards thiab Project Design
Dimensional qauv ua lub luag haujlwm tseem ceeb hauvpipeline tsim, muaj peev xwm txaus, thiab vuam compatibility. Cov kws tsim qauv yuav tsum xaiv cov yeeb nkab qhov ntau thiab tsawg raws li tsis yog ntawm kev ntsuas siab xwb tab sis kuj nyob ntawmntev muajthiabfabrication xav tau.
Piv txwv li:
API 5Ltsom rau kev thauj mus los rau cov roj thiab roj.
ASTM A106 1yog qhov zoo dua rau kev siv siab -kub.
TS EN 10216ua haujlwm rau European kev lag luam rau cov tshuab siab.
NtawmHuayang steel yeeb nkab, peb tuav tag nrho ua raws li cov qauv no, ua rau peb cov khoom siv los ntseeg siab hauv cov haujlwm thoob plawsAsia, Middle East, Africa, thiab South America.
7. Kev xaiv txiav thiab ntev
Txawm hais tias tus qauv kav ntev yog feem ntau 6m lossis 12m, Huayang kuj muabkev cai txiav cov kev pab cuamraws li qhov project xav tau. Qhov kev hloov pauv no txo qis cov khib nyiab thiab ua kom nrawm rau kev teeb tsa ntawm -site.
Cov haujlwm sib txawv yuav tsum muaj qhov ntev ntev:
Tsau Ntev (± 10mm):Zoo tagnrho rau prefabricated systems.
Random Ntev (5-12m):Siv rau cov kav xa dej thiab khiav mus ntev.
Exact Cut Length:Rau cov tshuab tseem ceeb xws li boiler raj.
