API 5L X52 PSL2 vs API 5L X60
| Khoom | X52 PSL 2 | X60 PSL 2 |
| Yield zog | 360 MPa siab | 415 MPa rau |
| Lub zog | Nruab nrab | Siab dua |
| Nqe | qis | Siab dua |
| Weldability | Zoo heev | Zoo |
| Hom kev siv | Roj & roj kis tau tus mob | Siab - cov kav dej siab |
Siv X52 thaum:
- Pipeline siab yog nruab nrab
- Kev tswj tus nqi yog qhov tseem ceeb
- Yuav tsum muaj weldability zoo heev
Siv X60 thaum:
- Yuav tsum tau ua haujlwm siab dua
- Cov yeeb nkab phab ntsa thickness txo yog xav tau
Vim li cas thiaj xaiv X52 hloov X60?
Ntau tus engineers xaiv X52 vim tias:
- Yooj yim vuam
- Tsawg fabrication txaus ntshai
- Cov khoom siv qis dua
- Muaj zoo dua
X60 / X65 tuaj yeem txo cov phab ntsa tuab, tab sis lawv xav tau kev tswj xyuas nruj dua.
API 5L X52 PSL2 puas tuaj yeem siv rau Sour Service?
Yog lawm, tab sis cov kev xav tau ntxiv yuav siv tau:

- Kev xeem SSC
- NACE ua raws
- Tswj hardness
Rau qhov chaw qaub qaub hnyav, engineers tuaj yeem xaiv:
- Duplex stainless hlau
- CRA kab yeeb nkab
Kev ua haujlwm kub
API 5L X52 tsis yog tsim los ua lub siab -kub alloy. Rau refinery furnace piping lossis siab -kub hydrogen kev pab cuam, ASTM A335 alloy kav yog ib txwm nyiam.
Vuam
| Hom yeeb nkab | Kev tsim khoom |
| Seamless | Kub dov + piercing |
| ERW/HFW | Hluav taws xob kuj welding |
| LSAW | Longitudinal submerged arc vuam |
| SSAW | Kauv submerged arc vuam |
Vim li cas API 5L X52 Cov yeeb nkab tawg tom qab vuam?
- Tshaj tawm cua sov
- Cov khoom siv welding tsis raug
- Cov ntsiab lus hydrogen siab
- Tsis zoo preheating tswj
Welding Advice: API 5L X52 PSL2 has excellent weldability, but the PSL2 status requires specific attention to the Carbon Equivalent (CE). Pre-heating is rarely required for thin-wall sections, but for walls >25mm, ua ntej- cua sov ntawm 100℃raug pom zoo los tiv thaiv Hydrogen Induced Cracking (HIC).
Test Peb muab:
- Hydrostatic Test: 100% hydrostatic test yam tsis muaj qhov xau los ntawm cov vuam seam lossis cov yeeb nkab lub cev xav tau.
- Khoov Kev Xeem: Tsis muaj cov kab nrib pleb yuav tsum tshwm sim hauv ib feem ntawm cov qauv lossis qhib qhov vuam.
- Flattening test: Flattening test siv los ua pov thawj cov yeeb nkab ua yeeb yam hauv qab deformation.
- Kev taw qhia-kev sim khoov: Ua kom tawg tag;
- CVN cuam tshuam kev xeem: (Yuav tsum tau PSL2 yeeb nkab, rau seamless yuav tsum tau sim nrog cov yeeb nkab lub cev, rau welded kev ntsuam xyuas nrog rau cov yeeb nkab lub cev, weld seam thiab tshav kub- cuam tshuam zon HAZ xeem)
- DWT xeem: (Yuav tsum tau rau PSL2 yeeb nkab)
