ERW Kab Yeeb Nkab rau Roj & Gas Pipeline
Peb ERW (Electric Resistance Welded) kab yeeb nkab yog siab -frequency welded carbon steel yeeb nkab engineered rau kev sib sau ua ke, kis tau tus mob, thiab faib cov roj, natural gas, thiab lwm yam roj av khoom. Ua los ntawm kub- dov steel coil los ntawm kev siab - zaus induction vuam txheej txheem ua raws li tag nrho - lub cev normalizing thiab tsis yog -kev kuaj kev puas tsuaj, peb cov ERW kab yeeb nkab xa cov qauv weld seam, cov phab ntsa tuab zoo ib yam, thiab txhim khu kev ua haujlwm siab thoob plaws qhov ntau thiab tsawg.
Tsis zoo li dav dav -Lub hom phiaj ERW yeeb nkab ua rau cov qauv lossis cov kua dej- cov qauv kev thauj mus los, cov kab yeeb nkab uas tsim los rau cov kev pabcuam roj thiab roj yog tsim, sim, thiab tau lees paub tshwj xeeb rau API 5L - npog weld seam kev ncaj ncees, kev sim hydrostatic, thiab cov cuab yeej cuab tam uas cov neeg ua haujlwm kav dej yuav tsum tau siv rau kev sib sau ua ke.
ERW PROCESS
Ntsiab nta
- Manufactured rauAPI 5L(PSL1 / PSL2) thiab ISO 3183 rau kab yeeb nkab kev pabcuam, nrog rauASTM A53thiab EN 10217 rau cov kev cai dav dav ERW yeeb nkab
- High- zaus induction vuam ua rau nqaim, tag nrho cov cua sov- cuam tshuam nrog qhov tsawg kawg ntawm qhov vuam tsis zoo
- 100% weld seam ultrasonic kuaj (UT) thiab kuaj hydrostatic ntawm txhua qhov ntev ua ntej xa zaub mov
- Muaj nyob rau hauv PSL1 thiab PSL2 qib zoo, nrog PSL2 muab cov chemistry nruj dua, tawv (Charpy impact), thiab NDT cov cai rau siab dua -siab lossis qaub- cov kav xa dej
- Bevel kawg, tiaj kawg, lossis threaded / coupled kawg tiav muaj nyob rau hauv qhov project specification
- Los tiv thaiv - kev xaiv txheej txheej corrosion: 3LPE, FBE, thee tar epoxy, lossis cov yeeb nkab liab qab rau cov neeg siv khoom
Qib
API 5LQib B, X42, X46, X52, X56, X60, X65, X70 (PSL1 thiab PSL2). Qib X- qib siab dua (X60 thiab siab dua) feem ntau tau teev tseg rau qhov ntev- nrug, siab- cov kav xa hluav taws xob uas cov phab ntsa thickness txo thiab qhov hnyav yog qhov tseem ceeb ntawm kev tsim; Qib B thiab X42 tseem muaj nyob rau hauv kev sib sau ua ke thiab qis dua - cov kev sib faib siab.
Daim Ntawv Loj & Phab Ntsa Thickness
| Sab nraud | NPS (hauv) | Phab ntsa Thickness | Kwv yees li. Qhov hnyav (kg / m) |
|---|---|---|---|
| 60.3mm ib | 2" | 3.9-5.5 hli | 5.4–7.5 |
| 114.3mm ib | 4" | 4.5-8.6 hli | 12.2–22.3 |
| 168.3mm ib | 6" | 5.0-11.0 hli | 20.1–42.4 |
| 2 19.1mm | 8" | 5.9-12.7 hli | 31.5–65.2 |
| 3 23,9mm | 12" | 6.4-17.5 hli | 50.0–128.6 |
| Txog li 630mm OD | Kev cai | mus txog 18mm | Ntawm kev thov |
Standard ntev: 6m, 12m, los yog random / ob chav random ntev (RL / DRL) rau API 5L. Kev cai ntev muaj nyob ntawm kev thov.
Qhov hnyav ntawm kev xam cov qauv
Luj (kg/m)=π × (OD − t) × t × 0.00785
Qhov twg OD=sab nraud (mm), t=phab ntsa thickness (mm). Qhov no yog tib cov qauv siv thoob plaws API 5L phab ntsa thickness cov rooj thiab cov qauv kab yeeb nkab hnyav kab kos, thiab nws siv sib npaug rau ib qho kev cai OD / phab ntsa - tuab ua ke tsis tau teev saum toj no - muaj txiaj ntsig rau kev txheeb xyuas cov ntawv pov thawj zeb los yog kwv yees cov raj xa hluav taws xob thaum lub sijhawm sib tw.
Cov lus nug nquag nug (FAQ)
Q: Qhov txawv ntawm ERW kab yeeb nkab thiab ERW cov yeeb nkab yog dab tsi?
A: ERW kab yeeb nkab yog tsim thiab sim rau API 5L, uas suav nrog kev sim hydrostatic xeem, vuam seam UT, thiab cov cuab yeej cuab yeej cuab tam tshwj xeeb rau cov kev pabcuam hauv cov kav dej. ERW cov qauv yeeb nkab, los ntawm qhov sib piv, feem ntau yog tsim los rau ASTM A500 lossis cov qauv zoo sib xws rau kev thauj khoom -cov qauv siv thiab tsis nqa API 5L ntawv pov thawj.
Q: Qhov txawv ntawm PSL1 thiab PSL2 kab yeeb nkab yog dab tsi?
A: PSL2 (Product Specification Level 2) muaj qhov yuav tsum tau nruj dua li PSL1 rau cov tshuaj muaj pes tsawg leeg, yuav tsum tau Charpy V-notch impact toughness tests, tighter tensile property ranges, and additional NDT - ua rau nws qhov kev xaiv ntau dua rau siab dua -cov kav xa hluav taws xob siab thiab qaub- PSL ib puag ncig txaus{1} kev pabcuam qis dua thiab faib kab.
Q: Puas ERW kab yeeb nkab hloov seamless kab yeeb nkab?
A: Rau feem ntau ntawm kev xa tawm thiab xa tawm ntawm ntug hiav txwv mus txog qib X70, API 5L- tau ntawv pov thawj ERW kab yeeb nkab yog qhov lees txais dav thiab tus nqi ntau dua - muaj txiaj ntsig zoo rau cov yeeb nkab seamless. Seamless yeeb nkab yog feem ntau teev rau siab -siab, siab- kub, los yog tseem ceeb qaub- ntu kev pab cuam qhov twg weld-seam- kev tsim kho dawb yog xav tau los ntawm tus neeg teb xov tooj specification.
