API 5L X52 ERW Pipe yog dab tsi?
API 5L X52 (tseem hu ua L360 raws li ISO{3}}raws li kev xaiv) yog carbon steel kab yeeb nkab qib nrog qhov tsawg kawg nkaus tawm lub zog ntawm 360 MPa (52,200 psi). Lub npe "X52" qhia txog qhov kev tawm dag zog lub zog, qhia hauv ntau txhiab psi.
X52 yeeb nkab tuaj yeem tsim los ntawm ntau txoj hauv kev - seamless, ERW, thiab submerged arc vuam (SAW/LSAW) - tab sis ERW yog cov txheej txheem ntau tshaj plaws thiab kev lag luam rau cov yeeb nkab nrog ib txoj kab uas hla sab nraud txog li 24 ntiv tes (610 hli). Thaum lub sij hawm ERW manufacturing, steel coil yog txias- ua rau hauv ib lub cylindrical zoo thiab cov seam yog koom nrog siab - zaus hluav taws xob kuj welding, tsis muaj ntxiv muab tub lim hlau. Qhov no ua rau cov yeeb nkab nrog cov phab ntsa tuab zoo ib yam, ib qho kev sib txuas du, thiab qhov zoo ntawm qhov tseeb.
X52 zaum hauv nruab nrab ntawm API 5L lub zog ntaiv - muaj zog dua qib B, X42, thiab X46, tab sis qis dua X56, X60, X65, thiab X70. Nws yog dav suav hais tias yog ib qho ntawm cov feem ntau txiav txim qib vim hais tias nws npog ntau yam ntawm onshore pipeline siab yuav tsum tsis muaj tus nqi ntxiv ntawm qib siab dua.
Tshuaj muaj pes tsawg leeg
API 5LX52 yeeb nkab muaj nyob rau ntawm ob yam khoom tshwj xeeb theem - PSL1 thiab PSL2 - txhua tus nrog cov kev txwv ntawm cov pa roj carbon, manganese, thiab cov khoom seem. Cov duab hauv qab no siv rau cov yeeb nkab nrog phab ntsa thickness Tsawg dua lossis sib npaug li 25 hli; hnyav phab ntsa yeeb nkab yuav raug kev sib tham nrog cov neeg tsim khoom.
| Element | PSL1 (welded) | PSL2 – X52N (Normalized) |
|---|---|---|
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.26% | Tsawg dua lossis sib npaug li 0.24% |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 1.40% | Tsawg dua lossis sib npaug li 1.40% |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.030% | Tsawg dua lossis sib npaug li 0.025% |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.030% | Tsawg dua lossis sib npaug li 0.015% |
| Nb + V + Ti | - | Tsawg dua lossis sib npaug li 0.15% |
| Copper (Cu) | Tsawg dua lossis sib npaug li 0.50% | Tsawg dua lossis sib npaug li 0.50% |
Manganese cov ntsiab lus tuaj yeem nce ntxiv los ntawm 0.05% rau txhua txhua 0.01% txo cov pa roj carbon, txog li 1.65%.
PSL2 yeeb nkab yuav raug nruj dua chemistry tswj thiab ntxiv microalloying (niobium, vanadium, titanium) los kho cov qauv nplej thiab txhim kho toughness - qhov no yog ib qho laj thawj PSL2 yeeb nkab feem ntau teev rau siab dua - qhov tshwm sim los yog qaub - cov kav xa dej.
Mechanical Properties

|---|---|---|
| Yield zog (min) | 360 MPa (52,200 psi) | 360-530 MPa (nyob ntawm tus me nyuam tus mob) |
| Tensile zog (min) | 460 MPa (66,700 psi) | 460-760 MPa |
| Weld Tensile zog | Ntau dua lossis sib npaug li 460 MPa | Ntau dua lossis sib npaug li 460 MPa |
| Elongation | Raws li API 5L formula raws li tus ntoo khaub lig-sectional cheeb tsam | Ib tus qauv API 5L, feem ntau Ntau dua lossis sib npaug li 21% |
| Yield/Tensile Ratio | Tsis txwv | Max . 0.93 (PSL2) |
PSL2 kuj tseem yuav tsum tau ua Charpy V- qhov ntsuas qhov cuam tshuam thiab ntsuas hydrostatic ntawm txhua qhov ntev ntawm cov yeeb nkab, nrog rau kev ua kom nruj dua qhov ntev dua PSL1 - cov neeg yuav khoom ua haujlwm ntawm cov kav raj xa dej yuav tsum paub meej tias PSL qib twg lawv qhov project specification xav tau ua ntej xaj.
Standard Sizes
ERW ntau lawm ntawm X52 yeeb nkab feem ntau npog:
Sab nraud txoj kab uas hla (OD):21.3mm - 630 hli
Phab ntsa Thickness (WT):2.0mm-18 hli
Ntev:Random lengths (5.8–12m) los yog tsau / ob npaug -random lengths ib tus neeg yuav tsum tau muaj

Kev Qhia Txog Kev Yuav Khoom: Yuav Ua Li Cas Ua Ntej Koj xaj
1. Paub meej tias PSL1 vs. PSL2 cov caiPSL2 yog qhov yuav tsum tau ua rau ntau qhov kev tswj hwm lossis cov kav dej tawm sab nraud thiab tuaj nrog kev sim nruj dua, nruj dua chemistry, thiab yuav tsum tau kuaj xyuas qhov cuam tshuam. Kev txiav txim siab tsis ncaj ncees lawm PSL qib yog ib qho kev ua yuam kev ntau tshaj plaws thiab raug nqi ntau hauv cov kab yeeb nkab yuav khoom.
2. Muab cov qhab nias rau koj qhov kev ua haujlwm siabX52 tsis yog qhov kev xaiv zoo ib txwm muaj - yog tias koj qhov project tsim lub siab thiab cov kav dej txoj kab uas hla hu rau qib siab dua -lub zog, siv X60 lossis X70 tuaj yeem txo cov phab ntsa tuab (thiab yog li qhov hnyav thiab tus nqi) rau tib qhov kev ntsuas siab. Tus neeg muag khoom uas tuaj yeem tawm tswv yim txog kev lag luam no - tawm, tsis yog tsuas yog muag cov qib koj thov, yog qhov tsim nyog ua ntej.
3. Txheeb xyuas cov ntaub ntawv vuam thiab kuajNug rau daim ntawv pov thawj zeb xeem (MTC) uas qhia cov tshuaj muaj pes tsawg leeg, cov txiaj ntsig kev ntsuas tshuab, thiab - rau PSL2 - Charpy cuam tshuam cov txiaj ntsig thiab cov ntaub ntawv ntsuas hydrostatic rau cov khoom siv tiag tiag, tsis yog cov ntaub ntawv dav dav.
4. Tshawb xyuas qhov yuav tsum tau ua ntawm lub npoo thiab txheejX52 yeeb nkab tuaj yeem muab tau liab qab, oiled, los yog nrog los tiv thaiv - cov txheej txheem corrosion (FBE, 3-txheej PE, thee tar epoxy) nyob ntawm qhov chaw teeb tsa. Paub meej tias qhov no tau teev meej meej hauv koj daim ntawv xaj khoom, vim tias cov txheej txheem txheej txheem cuam tshuam rau lub sijhawm ua haujlwm thiab tus nqi.
5. Paub meej tias qhov kawg tiav thiab ntim khoomKab yeeb nkab feem ntau yog muab nrog beveled xaus rau thaj chaw vuam. Qhia meej lub kaum sab xis, kev tiv thaiv kawg (cov kaus mom yas kawg), thiab cov kev cai bundling kom tsis txhob muaj kev puas tsuaj rau kev thauj mus los, tshwj xeeb tshaj yog rau kev xa tawm mus ntev -.
6. Nug txog NACE MR0175 ua raws li kev pabcuam qaubYog tias lub raj xa dej yuav nqa qaub (H2S-} muaj) cov xov xwm, paub meej tias tus neeg xa khoom tuaj yeem muab X52 cov kav dej sib ntsib NACE MR0175/ISO 15156 cov cai, uas suav nrog cov khoom siv ntxiv thiab cov khoom siv tswj.
FAQ
Q: Cov ntaub ntawv dab tsi yuav tsum tuaj nrog API 5L X52 yeeb nkab xaj?
A: Yam tsawg kawg nkaus, koj yuav tsum tau txais daim ntawv pov thawj zeb xeem (MTC) uas qhia cov lej ntsuas kub, cov tshuaj muaj pes tsawg leeg, thiab cov txiaj ntsig kev ntsuas tshuab rau qhov tseeb ntau lawm. Rau PSL2 kev txiav txim, qhov no kuj tseem yuav suav nrog Charpy qhov kev sim cuam tshuam thiab cov ntaub ntawv ntsuas hydrostatic. Yog tias cov yeeb nkab nqa API monogram, daim ntawv pov thawj yuav tsum xa mus rau API daim ntawv tso cai tus lej, uas cov neeg yuav khoom tuaj yeem txheeb xyuas qhov API tus kheej daim ntawv tso cai database.
Q: Yuav ua li cas yog qhov yuav tsum tau phab ntsa thickness rau X52 yeeb nkab xam?
A: Phab ntsa tuab feem ntau txiav txim siab siv cov qauv tsim cov raj xa dej (xws li Barlow's formula) raws li cov qauv tsim, cov yeeb nkab sab nraud txoj kab uas hla, tso cai rau kev ntxhov siab (feem pua ntawm SMYS), thiab cov qauv tsim los ntawm cov kav dej siv tau. Qhov kev suav no yuav tsum tau ua los ntawm tus kws tshaj lij cov kav dej uas tsim nyog es tsis yog xaiv los ntawm phab ntsa- tuab "txoj cai ntawm tus ntiv tes xoo," txij li hauv qab - qhia txog phab ntsa thickness yog qhov teeb meem kev nyab xeeb.
Q: API 5L X52 ERW puas tuaj yeem kub -dip galvanized?
A: Yog lawm, X52 ERW yeeb nkab tuaj yeem kub -dip galvanized rau kev tiv thaiv corrosion saum toj no - hauv av lossis tsis - daim ntaub ntawv faus. Rau cov kev pabcuam faus rau hauv cov kav dej, cov txheej txheej sab nraud xws li 3- txheej PE (3LPE) lossis fusion-bonded epoxy (FBE) feem ntau tau teev tseg ntau dua li galvanizing, vim lawv muab kev tiv thaiv ntev dua - tiv thaiv av-sab corrosion.
Q: Dab tsi cuam tshuam rau lub sijhawm ua haujlwm thaum xaj API 5L X52 ERW yeeb nkab?
A: Cov yam ntxwv muaj xws li kev txiav txim kom muaj nuj nqis, seb qhov yuav tsum tau ua OD / WT ua ke yog twb nyob rau hauv ntau lawm los yog yuav tsum tau teem caij, PSL2 xeem yuav tsum tau (uas ntxiv sij hawm soj ntsuam), txheej yuav tsum tau, thiab export packing / ntaub ntawv. Cov neeg yuav khoom ua haujlwm rau lub sijhawm kawg ntawm qhov project yuav tsum paub meej tias lub sijhawm ua haujlwm hauv kev sau ntawv ua ntej muab daim ntawv xaj, tshwj xeeb tshaj yog rau PSL2 lossis cov yeeb nkab coated.
