— Ib Phau Ntawv Qhia Tag Nrho rau Tus Txheej Txheem Lavxias rau Kev Ua Roj Refining & Petrochemical Kev Lag Luam
Kev Lag Luam Yeeb Nkab Sanon - Koj Tus Neeg Muab Khoom Uas Ntseeg Tau ntawm GOST Cov Yeeb Nkab Hlau Uas Tiv Thaiv Kub
1. Txheej Txheem Txheem & Cov Khoom Siv
15Х5М (Latin spelling: 15Kh5M) yog ib hom yeeb nkab hlau uas tsis kub hnyiab raws li Lavxias GOST system, tsim tawm raws li GOST 550‑2020 (Cov Kav Hlau Tsis Muaj Qhov Txuas Rau Kev Ua Roj thiab Kev Lag Luam Petrochemical). Nws kuj tseem sib xws nrog cov qauv thoob ntiaj teb xws liASTM A335 P5.
Cov khoom siv no yog cov hlau uas tsis tshua muaj zog thiab tiv taus cua sov uas yog chromium-molybdenum. Nws cov txiaj ntsig tseem ceeb yog kev ruaj khov zoo heev thaum kub thiab txias, tiv taus kev nkag mus, thiab tiv taus kev xeb nruab nrab. Nws ua haujlwm tau zoo hauv qab qhov kub thiab txias thiab siab thiab siv tau ntev, ua rau nws siv dav hauv kev tsim cov kav dej thiab cov khoom siv uas nyuaj.
Kev txhais lub npe qib:
Cov ntsiab lus carbon 15 ≈ 0.15%
Х (Kh) = Chromium (Cr)
5 ≈ 5% chromium
M (M) = Molybdenum (Mo)
Nrog keeb kwm ntev hauv kev lag luam Lavxias thiab ntau qhov kev hloov kho tus qauv (GOST 550‑75 → GOST 550‑2020), cov kev cai lij choj tau raug hloov kho tas li, ua kom qib no ruaj khov ua cov khoom siv rau kev ua roj thiab kev siv petrochemical.
2. Kev Tshuaj Lom Zem & Kev Tswj Xyuas Kev Huv Si
Raws li GOST 550‑2020, cov tshuaj lom neeg ntawm 15Х5М yog raws li nram no:
| Khoom | Cov Ntsiab Lus Ntau (%) | Lub luag haujlwm |
|---|---|---|
| C (Cov pa roj carbon) | ≤0.15 | Sib npaug zog thiab kev tawv, txo qhov kev pheej hmoo ntawm kev vuam tawg |
| Si (Silicon) | ≤0.50 | Txhim kho kev tiv thaiv oxidation thiab kev ruaj khov kub siab |
| Mn (Manganese) | ≤0.50 | Txhim kho qhov ua haujlwm kub thiab ua rau lub zog ntxiv |
| Cr (Chromium) | 4.50‑6.00 | Tsim ib zaj duab xis oxide ntom ntom, muab kev tiv thaiv corrosion thiab cua sov |
| Mo (Molybdenum) | 0.45‑0.60 | Ua kom muaj zog kub thiab tiv taus kev nkag mus |
| Ni (Nickel) | ≤0.60 | Txhim kho qhov tawv nqaij qis-kub |
| P (Phosphorus) | ≤0.030 | Tswj cov brittleness txias |
| S (Sulfur) | ≤0.025 | Txo qhov kev pheej hmoo ntawm kev kub hnyiab |
Qhov kev sib koom ua ke ntawm chromium (Cr) thiab molybdenum (Mo) tsim ib txheej oxide tiv thaiv rau ntawm qhov chaw hlau, ua kom zoo tiv taus qhov kub siab oxidation thiab corrosive media.
3. Cov Khoom Siv Kho Tshuab & Kev Kho Mob Kub
Nyob rau hauv tus me nyuam mob (normalized + tempered), 15Х5М seamless kav dej yuav tsum ua tau raws li cov khoom siv kho tshuab hauv qab no:
| Vaj tse | Tus nqi | Kev Ntsuas Tus Qauv |
|---|---|---|
| Lub zog tensile | ≥ 392 MPa | — |
| Lub Zog Tawm | ≥ 216 MPa | — |
| Kev ntev | ≥ 22% | — |
| Qhov nyuaj (HB) | ≤ 197 HB | — |
Cov txheej txheem kho cua sov: Ua kom zoo li qub (900‑950°C) + Tempering (650‑700°C) - tshem tawm cov kev ntxhov siab seem thiab ua kom cov qauv noob zoo dua. Qhov kub tseem ceeb: Ac1 = 815°C, Ac3 = 848°C.
Kev vuam tau: Kev vuam tau nruab nrab. Pom zoo kom ua ntej cua sov (feem ntau yog 150‑200°C), thiab pom zoo kom kho cua sov tom qab vuam kom txo kev ntxhov siab.
4. Cov Ntawv Thov Ib Txwm Muaj
Cov yeeb nkab hlau no siv dav hauv cov xwm txheej kub thiab siab hauv qab no:
| Daim Ntawv Thov | Kev Siv Tshwj Xeeb | Cov xwm txheej ua haujlwm |
|---|---|---|
| Kev Ua Roj | Cov raj cua sov tawg, cov kav dej reactor, cov khoom sib pauv cua sov, cov kab ntsuas | Tiv taus txog li 600 ° C, tiv taus hydrogen embrittlement thiab sulfur corrosion |
| Kev Lag Luam Petrochemical | Cov kav dej ua haujlwm kub siab, cov khoom siv sab hauv, cov khoom twj tso kua mis | Kev raug rau lub sijhawm ntev rau cov khoom siv kub thiab siab |
| Kev Tsim Hluav Taws Xob | Cov raj xa dej kub siab, cov seem rov ua kom sov | Tiv taus qhov siab tshaj 10 MPa |
| Kev Pabcuam Kub Siab Dav Dav | Kev ua haujlwm tas mus li saum 500 ° C | Kev ruaj khov ntev ntawm qhov kub siab |
Qhov kub siab tshaj plaws uas pom zoo kom siv yog 600°C. Hauv cov cub tawg roj, nws txoj kev tiv taus hydrogen thiab sulfur corrosion ua rau lub neej ntawm cov khoom siv ntev dua.
5. Cov Qib Sib Npaug Thoob Ntiaj Teb
15Х5М sib raug rau ntau tus qauv thoob ntiaj teb, ua rau kev nrhiav khoom thoob ntiaj teb thiab kev hloov pauv yooj yim dua:
| Txheej Txheem Txheem | Qib Sib Npaug |
|---|---|
| Tuam Tshoj (GB) | 12Cr5Mo (lub npe tshiab) / 1Cr5Mo (qub) |
| Tebchaws Meskas (ASTM/ASME) | A335 P5(yeeb nkab) / SA387 Gr.5 (phaj) / A182 F5 (forgings) |
| Tebchaws Europe (EN) | X12CrMo5 (cov khoom siv lej 1.7362) |
| Nyiv Pooj (JIS) | STBA25 |
Lus Cim Txog Kev Yuav Khoom: 15Х5М yog cov khoom siv tshuaj lom neeg thiab tshuab zoo ib yam li Tuam Tshoj GB/T 9948 qib 12Cr5Mo. Cov chaw tsim khoom hauv Suav teb tuaj yeem tsim cov khoom raws li cov lus qhia ntawm Lavxias, thiab daim ntawv pov thawj khoom siv tuaj yeem teev cov qib sib npaug ntawm GOST thiab GB/ASME thaum thov.
6. Txheej Txheem Tsim Khoom & Kev Ntsuas Zoo
Cov kav dej seamless 15Х5М yog tsim los ntawm cov txheej txheem hauv qab no:
Kev tho qhov kub: Cov hlau kheej kheej uas kub txog 1200‑1300°C, tom qab ntawd tho los ntawm lub tshuab tho qhov rotary kom ua cov plhaub khoob.
Kev dov tas mus li: Siv lub tshuab dov tas mus li uas khaws cia kom zoo dua qhov tuab ntawm phab ntsa, nrog rau kev kam rau OD tswj tau hauv ± 0.5%.
Kev kho cua sov: Ua kom zoo li qub (900‑950°C) + Tempering (650‑700°C) - tshem tawm cov kev ntxhov siab seem thiab ua kom cov qauv noob zoo dua.
Kev sim tsis ua puas tsuaj: Kev sim ultrasonic (UT) thiab kev sim eddy tam sim no (ET) ua kom tsis muaj qhov tsis zoo sab hauv.
Kev lav zoo:
Txhua pawg khoom muaj Daim Ntawv Pov Thawj Xeem Zeb (MTC) tiav.
Peb tuaj yeem muab daim ntawv pov thawj EN 10204 Hom 3.1 lossis 3.2.
Kev tshuaj xyuas los ntawm cov neeg thib peb los ntawm SGS, BV, TÜV tau txais kev txhawb nqa.
Kev taug qab tag nrho los ntawm tus lej cua sov mus rau cov khoom tiav.
7. EU CBAM Carbon Tariff - Xaiv Sanon kom Txo Cov Nqi Ua Raws Cai
Txij li hnub tim 1 Lub Ib Hlis Ntuj xyoo 2026, EU Carbon Border Adjustment Mechanism (CBAM) tau raug siv tag nrho, nrog rau kev lag luam hlau yog thawj qhov hauv kab. Yog tias koj tsis tuaj yeem muab cov ntaub ntawv tso pa tawm tiag tiag, EU yuav siv cov nqi tsis raug - raws li qhov nruab nrab ntawm 10 lub tebchaws uas tso pa tawm ntau tshaj plaws thoob ntiaj teb - uas txhais tau tias cov nqi se carbon siab dua.
Sanon Pipe Industry tau koom tes nrog TÜV NORD los pab cov chaw tsim khoom npaj rau kev ua raws li CBAM:
Cov ntaub ntawv ntsuas tiag tiag: Peb tuaj yeem muab cov ntaub ntawv txog kev tso pa roj carbon dioxide rau cov khoom lag luam raws li kev ntsuas qhov chaw tiag tiag, pab koj zam kev raug nplua.
Kev taug qab tag nrho: Cov ntawv qhia txog kev tso pa tawm los ntawm cov khoom siv raw mus rau cov khoom xa tawm tiav.
Kev pabcuam ua raws li txoj cai ib zaug xwb: Kev pabcuam nrog cov phiaj xwm saib xyuas, cov ntawv qhia txog kev tso pa tawm, kev kuaj cov ntaub ntawv, thiab 9 daim ntawv tshuaj xyuas tseem ceeb.
Kev xaiv Sanon txhais tau tias tsis yog tsuas yog cov kav hlau zoo xwb, tab sis kuj yog tus khub zoo rau kev taug kev EU CBAM carbon cov cai nrog kev ntseeg siab.
