P110 yog qib siab -qib seamless steel yeeb nkab rau kev siv roj av raws li API 5CT tus qauv, muaj nyob rau qis- alloy siab- lub zog steel. Nws cov txiaj ntsig tseem ceeb yog:
Lub zog siab load-cov kabmob muaj peev xwm: Lub zog muaj zog nce mus txog 758-965MPa, lub zog tensile Ntau dua lossis sib npaug rau 862MPa, haum rau ultra- qhov dej tob thiab cov roj thiab cov pa roj;
Corrosion kuj: Los ntawm optimized tshuaj muaj pes tsawg leeg (xws li tus piv ntawm chromium thiab molybdenum), nws muaj peev xwm tiv taus qhov yaig ntawm corrosive media xws li H₂S;
Txheej txheem kev sib raug zoo: Txhawb kev kos duab txias, kub dov, thiab cov txheej txheem kho cua sov kom tau raws li qhov xav tau ntawm engineering sib txawv.
Raws li cov khoom siv tseem ceeb rau oilfield casing, P110 yog dav siv nyob rau hauv shale gas extraction, coalbed methane txoj kev loj hlob, thiab geothermal zoo tsim.
Kev soj ntsuam tshuaj muaj pes tsawg leeg ntawm P110 cov ntaub ntawv raws li API 5CT tus qauv
| Tshuaj muaj pes tsawg leeg | Cov ntsiab lus Range(%) |
|---|---|
| C | 0.26 - 0.35 |
| Si | 0.17 - 0.37 |
| Mn | 0.40 - 0.70 |
| Cr | 0.80 - 1.10 |
| Mo | 0.15 - 0.25 |
| P | Tsawg dua lossis sib npaug li 0.020 |
| S | Tsawg dua lossis sib npaug li 0.010 |
Cov ntsiab lus carbon ncaj qha cuam tshuam rau qib zog ntawm P110; Tshaj li 0.35% tuaj yeem ua rau muaj kev cuam tshuam rau vuam tawg.
Cov nyhuv synergistic ntawm chromium thiab molybdenum tso cai rau nws kom muaj kev ruaj ntseg hauv sulfur - muaj ib puag ncig.
Mechanical zog
| Performance Indicators | Standard Requirements |
|---|---|
| Tensile zog (MPa) | Ntau dua lossis sib npaug rau 862 |
| Yield zog (MPa) | 758 - 965 |
| Elongation (%) | Ntau dua lossis sib npaug li 18 |
| Impact Test | Lub zog cuam tshuam loj dua lossis sib npaug rau 27J ntawm -20 degree |
| Hardness | Tsawg dua lossis sib npaug rau 241HB (Brinell Hardness) |
Kev tsim tawm lub zog ntau yam tsim siv rau hauv tus account ob qho tib si lub siab xav tau ntawm qhov tob tob thiab qhov ua tau ntawm cov khoom siv;
Qhov ntsuas kub ntawm qhov ntsuas kub yog teem rau ntawm -20 degree, npog feem ntau cov roj hauv cheeb tsam txias thiab roj av.
Kev Muag Khoom thiab Kev Ua Haujlwm Zoo
Raws li tus tswj hwm nruj ntawm API 5CT tus qauv, peb cov P110 seamless steel kav muaj cov txiaj ntsig hauv qab no:
Tag nrho- txheej txheem tswj kom zoo: Los ntawm steelmaking mus rau kev kho cua sov, txhua batch ntawm cov khoom raug kuaj ultrasonic, hardness testing, thiab cuam tshuam kev kuaj;
Customized cov kev pabcuam: Peb txhawb cov xov tshwj xeeb, txheej txheej txheej, thiab kev ua kom zoo dua qub kom ua tau raws li qhov xav tau ntawm cov xwm txheej tshwj xeeb xws li shale roj thiab lub zog hauv av;
Kev cog lus ntawm kev koom tes: Peb cov khoom tau dhau API Q1 daim ntawv pov thawj thiab muab cov ntaub ntawv pov thawj thib peb -, muab kev tiv thaiv tag nrho rau koj cov haujlwm engineering.
