Sanonpipe - Koj Tus Neeg Muab Khoom Uas Ntseeg Tau ntawm GOST Tus Qauv Kub-Tiv Thaiv Cov Kav Hlau
1. Txheej Txheem Txheem & Kev Tso Khoom Siv
15Х5М(Latin transliteration: 15Kh5M) yog ib qho yeeb nkab hlau uas tsis kub hnyiab raws li Lavxias teb sab GOST tus qauv, siv raws liGOST 550-2020(Cov Kav Hlau Seamless rau Kev Ua Roj thiab Kev Lag Luam Petrochemical), thaum tseem ua raws li cov qauv thoob ntiaj teb xws li ASTM A335 P5. Qib no yog rauCr-Mo cov hlau tsis tshua muaj zog tiv taus cua sovtsev neeg. Nws lub zog tseem ceeb yog nyob rau hauv kev ruaj khov zoo heev thaum kub siab, tiv taus kev nkag, thiab tiv taus kev xeb nruab nrab, ua rau kev ua haujlwm ruaj khov mus sij hawm ntev hauv qab qhov kub thiab txias thiab siab. Nws yog siv dav hauv kev thauj mus los hauv cov kav dej tshwj xeeb thiab cov xwm txheej tsim khoom siv.
Kev faib tawm ntawm cov khoom siv: 15qhia txog cov pa roj carbon ntawm kwv yees li 0.15%;Хsawv cev rau Chromium (Cr);5qhia txog cov ntsiab lus Chromium ntawm li 5%;Мsawv cev rau Molybdenum (Mo). Qib no muaj keeb kwm ntev hauv kev lag luam Lavxias, tau dhau los ntawm ntau qhov kev hloov kho tus qauv (GOST 550-75 → GOST 550-2020), nrog rau kev hloov kho tas li. Nws tau dhau los ua ib qho ntawm cov ntaub ntawv txheem rau kev lag luam roj thiab 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 (%) | Kev Tshawb Fawb Txog Kev Ua Haujlwm |
| C (Cov pa roj carbon) | ≤0.15 | Sib npaug lub zog thiab kev tawv, txo qhov kev pheej hmoo ntawm kev vuam tawg |
| Si (Silicon) | ≤0.50 | Txhim kho kev tiv thaiv oxidation, txhim kho kev ruaj ntseg kub siab |
| Mn (Manganese) | ≤0.50 | Txhim kho qhov ua haujlwm kub, 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 kev hloov pauv ntawm qhov 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 cov txheej oxide ntom ntom ntawm cov hlau, ua kom zoo tiv taus qhov kub siab oxidation thiab corrosion nruab nrab.
3. Cov Khoom Siv Kho Tshuab & Cov Kev Xav Tau Kev Kho Mob Kub
Nyob rau hauv tus me nyuam mob (normalized + tempered), 15Х5М seamless steel yeeb nkab yuav tsum ua tau raws li cov khoom siv kho tshuab hauv qab no:
| Qhov Ntsuas Kev Ua Tau Zoo | Tus nqi | Kev Ntsuas Txheem |
| Lub zog tensile (σb) | ≥ 392 MPa | — |
| Lub Zog Tawm (σs) | ≥ 216 MPa | — |
| Kev ntev (δ5) | ≥ 22% | — |
| Qhov nyuaj (HB) | ≤ 197 HB | — |
Cov Txheej Txheem Kho Mob Kub:Kev ua kom zoo li qub (900-950°C) + Kev ua kom sov (650-700°C) – tshem tawm cov kev ntxhov siab seem thiab ua kom cov qauv ntawm cov noob zoo dua. Qhov kub tseem ceeb: Ac1 = 815°C, Ac3 = 848°C.
Kev vuam tau:Cov khoom siv no muaj peev xwm vuam tau nruab nrab. Yuav tsum tau ua kom sov ua ntej (feem ntau yog 150-200°C) thaum lub sijhawm vuam, thiab kev kho cua sov tom qab vuam kom txo qhov kev ntxhov siab yog qhov pom zoo.
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 Av | Cov raj cua sov tawg, cov kav dej reactor, cov khoom sib pauv cua sov, cov kab ntsuas | Tiv taus txog li600°C, tiv taus hydrogen embrittlement thiab sulfur corrosion |
| Kev Lag Luam Petrochemical | Cov txheej txheem kav dej kub, cov khoom siv sab hauv, cov khoom twj tso kua mis | Kev raug rau lub sijhawm ntev rau cov xov xwm kub thiab siab |
| Lub zog thiab lub zog | Cov raj xa dej kub siab, cov seem rov ua kom sov | Tiv taus qhov siab tshaj 10 MPa |
| Cov Xwm Txheej Kub Siab | Kev ua haujlwm tas mus lisiab tshaj 500 ° C | Kev ua haujlwm ruaj khov ntev hauv qab qhov kub heev |
Qhov kub siab tshaj plaws uas pom zoo kom siv tau600°CHauv cov chaw ua kom tawg cov khoom siv roj, nws txoj kev tiv thaiv rau hydrogen embrittlement thiab sulfur corrosion ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua.
5. Cov Qauv Thoob Ntiaj Teb Sib Npaug
15Х5М sib raug zoo nrog ntau qib thoob ntiaj teb, ua rau kev nrhiav tau thiab hloov pauv thoob ntiaj teb yooj yim dua:
| Txheej Txheem Txheem | Qib Sib Npaug |
| Tuam Tshoj (GB) | 12Cr5Mo(lub npe tshiab) /1Cr5Mo(lub npe qub) |
| Tebchaws Meskas (ASTM/ASME) | A335 P5(cov yeeb nkab tsis muaj qhov sib txuas) /SA387 Qib 5(phaj) /A182 F5(cov khoom siv forging) |
| Tebchaws Europe (EN) | X12CrMo5(tus lej lej 1.7362) |
| Nyiv Pooj (JIS) | STBA25 |
Lus Cim Txog Kev Yuav Khoom:15Х5М yog sib xws nrog Suav teb tus qauv GB / T 994812Cr5Mohauv ob qho tib si tshuaj lom neeg thiab cov khoom siv kho tshuab. Cov chaw tsim khoom hauv Suav teb tuaj yeem tsim khoom raws li cov lus txib ntawm Lavxias, thiab daim ntawv pov thawj khoom siv tuaj yeem teev cov qib sib npaug ntawm Lavxias thiab Suav / Asmeskas tib lub sijhawm.
6. Cov Txheej Txheem Tsim Khoom & Kev Ntsuas Zoo
Cov kav hlau tsis muaj seamless 15Х5М yog tsim los ntawm cov txheej txheem tsim khoom hauv qab no:

7. EU CBAM Carbon Tariff: Xaiv Sanonpipe kom txo cov nqi ua raws li txoj cai
Txij li thaum Lub Ib Hlis 1, 2026, EU Carbon Border Adjustment Mechanism (CBAM) tau nkag mus rau hauv nws theem kev sau cov pa roj carbon dioxide, nrog rau kev lag luam hlau yog lub hom phiaj tseem ceeb. Yog tias cov ntaub ntawv tso pa tawm tiag tiag tsis tuaj yeem muab tau, EU yuav siv cov nqi tsis raug - raws li qhov nruab nrab ntawm 10 lub tebchaws uas tso pa tawm ntau tshaj plaws hauv ntiaj teb - uas txhais tau tiascov nqi them rau cov pa roj carbon ntau dua.
Sanonpipe tau koom tes nrog TÜV Nord los pab cov chaw tsim khoom hauv kev npaj ua raws li CBAM:
Kev Txhawb Nqa Cov Ntaub Ntawv Ntsuas:Peb tuaj yeem muab cov ntaub ntawv txog kev tso pa roj carbon rau cov khoom lag luam raws li kev ntsuas ntawm qhov chaw, pab koj zam kev nplua rau tus nqi tsis raug.
Kev taug qab tag nrho:Cov ntawv qhia txog kev tso pa tawm tag nrho los ntawm kev siv cov khoom siv raw mus rau kev xa khoom tiav
Kev Pabcuam Ua Raws Cai Ib Zaug Xwb:Kev pab hauv kev npaj cov phiaj xwm saib xyuas, cov ntawv qhia txog kev tso pa tawm, kev kuaj cov ntaub ntawv, thiab 8 lwm cov ntaub ntawv tseem ceeb ntawm kev tshuaj xyuas
Kev xaiv Sanonpipe txhais tau tias tsis yog tsuas yog xaiv cov kav hlau zoo xwb, tab sis kuj xaiv tus khub zoo rau kev ua raws li EU carbon tariff.
