1. API 5L yog dab tsi? – Ntiaj teb no Standard rau Kab Pipes
API 5Lyog tus txheej txheem thoob ntiaj teb siv dav tshaj plaws raukab cevsiv nyob rau hauvpetroleum, natural gas, oilfield sau thiab thauj, thiab pipeline engineering industries.Qhov no yog lub ntiaj teb no benchmark rau pipeline pipelines, thiab kev nkag siab nws yog ib qho tseem ceeb rau tej export rau cov cheeb tsam xws li Brazil, Middle East, los yog Southeast Asia, raws li ntau tej yaam num txais yuav nws ib sab los yog es tsis txhob ntawm lub zos NBR los yog lwm yam qauv.
ERW (Electric Resistance Welded Yeeb Nkab)
-Ua los ntawm siab - zaus kuj welding(HFW)
-Ncaj longitudinal weld (welded seam ntawm cov yeeb nkab hauv)
-High dimensional precision, zoo nto zoo
-Feem ntau yog siv rau cov kav dej hiav txwv, cov kav dej, kev siv cov qauv, thiab lwm yam.
-OD: 21.3–610mm (1/2"–24")|Phab ntsa: 1.6–20mm|Ntev: 6m / 12m
Qib X42 & X46belongs rau lubnruab nrab -strength kab yeeb nkab seriesRaws li API 5L.
Ua ntej quoting API 5L X42 / X46 ERW kav, nco ntsoov xyuas:
1.Qib – X42 lossis X46?
2.PSL Level – PSL1 lossis PSL2? (Qhov no txiav txim siab 5-15% tus nqi sib txawv)
3.Size range – OD thiab phab ntsa thickness (piv txwv li, 219mm OD × 6.35mm WT)
4.Ntev – Random (feem ntau 6–12m) lossis kho?
5.Xaus xaus - Plain kawg, beveled kawg, los yog threaded?
6.Txheej - Liab qab, 3PE, FBE, lossis lwm yam?
7.Quantity – Ton los yog tag nrho cov Pieces los yog Meters
8.Destination - Txhawm rau kom paub meej tias yuav tsum muaj ntawv pov thawj hauv cheeb tsam (INMETRO, thiab lwm yam)
9.Mill daim ntawv pov thawj - EN 10204 Hom 3.1 lossis 3.2?
10.Thib peb -kev tshuaj ntsuam xyuas - SGS, BV, lossis tus neeg siv khoom- raug xaiv?

Cov Kev Ntsuas Tseem Ceeb rau ERW Yeeb Nkab (PSL1 vs. PSL2):
| Kuaj | PSL1 | PSL2 |
| Hydrostatic Test | Yuav tsum tau | Yuav tsum tau (siab dua margin) |
| Flattening Test | Yuav tsum tau | Yuav tsum tau |
| Charpy V-Qhov cuam tshuam | Tsis xav tau | Yuav tsum tau (pipe lub cev + weld seam) |
| Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT) | Visual + xaiv tau | Ultrasonic / Radiographic yuav tsum tau |
| Tensile Test (Weld Seam) | Tsis xav tau | Yuav tsum tau |
Thaum Yuav Qhia PSL1 vs. PSL2
| PSL1 yog tsim rau: | PSL2 yuav tsum muaj rau: |
| Tsawg-kev sib sau ua ke / ntws kab | Hla -cov roj & roj xa hluav taws xob hauv lub tebchaws |
| Tsis yog -kev faib dej tseem ceeb | Offshore thiab subsea pipelines |
| Ib ntus lossis luv luv -kev pabcuam- lub neej kav dej | Kev pabcuam qaub (H₂S-muaj ib puag ncig) |
| Tus nqi -tsim cov haujlwm uas ua rau tsis ua haujlwm tsawg | Siab -pas kis kab mob |
| Cov kav xa dej hauv Cov Kev Sib Haum Siab Loj (HCAs) raws li cov cai tswj hwm |
