— Isikhokelo Esipheleleyo kwiMigangatho yaseRashiya yokuCoca iOyile kunye neeNkampani zePetrochemical
Ishishini leeMpayipi zeSanon – Umthengisi wakho othembekileyo weeMpayipi zeNsimbi ezimelana nobushushu zeGOST
1. Inkqubo eQhelekileyo kunye noBuchule beZinto
I-15Х5М (upelo lwesiLatini: 15Kh5M) ludidi lombhobho wentsimbi engenamthungo enganyangekiyo kubushushu phantsi kwenkqubo ye-GOST yaseRashiya, eyenziwe ngokuhambelana ne-GOST 550‑2020 (Iipayipi zeNtsimbi ezingenamthungo zokuCoca iOyile kunye neePetrochemical IndustriesIkwahambelana nemigangatho yamazwe ngamazwe efana neI-ASTM A335 P5.
Le nto iyinxalenye yosapho lwentsimbi olumelana nobushushu oluphantsi lwe-chromium-molybdenum. Iingenelo zayo eziphambili kukuzinza okuphezulu kobushushu, ukumelana nokuqhekeka, kunye nokumelana nokugqwala okuphakathi. Isebenza ngokuthembekileyo phantsi kweemeko zobushushu obuphezulu kunye noxinzelelo oluphezulu ngexesha elide lokusebenza, nto leyo eyenza ukuba isetyenziswe kakhulu kwiinkqubo zombhobho ezifuna amandla kunye nemveliso yezixhobo.
Ukucazulula igama lebanga:
Umxholo wekhabhoni oyi-15 ≈ 0.15%
Х (Kh) = I-Chromium (Cr)
5 ≈ 5% i-chromium
М (M) = iMolybdenum (Mo)
Ngembali ende kushishino lwaseRashiya kunye nohlaziyo oluninzi olusemgangathweni (GOST 550‑75 → GOST 550‑2020), iimfuno zobugcisa ziye zaphuculwa rhoqo, nto leyo eyenza olu didi luqine njengesixhobo sokulinganisa ukucocwa kweoyile kunye nokusetyenziswa kwepetrochemical.
2. Ukwakhiwa kweeKhemikhali kunye noLawulo lokuCoca
Ngokutsho kweGOST 550‑2020, ukwakheka kweekhemikhali ze-15X5М ngolu hlobo lulandelayo:
| I-elementi | Uluhlu Lomxholo (%) | Indima |
|---|---|---|
| C (Ikhabhoni) | ≤0.15 | Ilinganisela amandla kunye nokuqina, inciphisa umngcipheko wokuqhekeka kwe-welding |
| I-Si (iSilicon) | ≤0.50 | Iphucula ukumelana ne-oxidation kunye nozinzo lobushushu obuphezulu |
| I-Mn (iManganese) | ≤0.50 | Iphucula ukusebenza kakuhle kobushushu kwaye yonyusa amandla |
| I-Cr (iChromium) | 4.50‑6.00 | Yenza ifilimu ye-oxide exineneyo, enika ukugqwala kunye nokumelana nobushushu |
| IMo (iMolybdenum) | 0.45‑0.60 | Inyusa amandla obushushu obuphezulu kunye nokumelana nokurhubuluza |
| I-Ni (iNickel) | ≤0.60 | Iphucula ukuqina kobushushu obuphantsi |
| I-P (iPhosphorus) | ≤0.030 | Ilawula ukubanda okubuthathaka |
| S (Isalfure) | ≤0.025 | Yehlisa umngcipheko wokunqongophala kobushushu |
Isiphumo sokusebenzisana kwe-chromium (Cr) kunye ne-molybdenum (Mo) kudala umaleko we-oxide okhuselayo kumphezulu wentsimbi, ochasa ngempumelelo i-oxidation yobushushu obuphezulu kunye ne-corrosive media.
3. Iipropati zoomatshini kunye nonyango lobushushu
Kwimeko yokuhanjiswa (eqhelekileyo + ethambileyo), imibhobho engenamthungo ye-15Х5М kufuneka ihlangabezane nezi mpawu zilandelayo zoomatshini:
| Ipropati | Ixabiso | Umgangatho woVavanyo |
|---|---|---|
| Tensile strength | ≥ 392 MPa | — |
| Unikeze Amandla | ≥ 216 MPa | — |
| Ukwandiswa | ≥ 22% | — |
| Ubunzima (HB) | ≤ 197 HB | — |
Inkqubo yokunyanga ubushushu: Ukulungisa (900‑950°C) + Ukushisa (650‑700°C) – kususa uxinzelelo olushiyekileyo kwaye kuphucule isakhiwo sengqolowa. Amaqondo obushushu abalulekileyo: Ac1 = 815°C, Ac3 = 848°C.
Ukuwelda: Ukuwelda okuphakathi. Kucetyiswa ukufudumeza (ngesiqhelo i-150‑200°C), kwaye kuyacetyiswa unyango lobushushu emva kokuwelda.
4. Izicelo eziqhelekileyo
Lo mbhobho wentsimbi usetyenziswa kakhulu kwezi meko zilandelayo zobushushu obuphezulu kunye noxinzelelo oluphezulu:
| Intsimi yesicelo | Iindlela Ezithile Zokusebenzisa | Iimeko Zokusebenza |
|---|---|---|
| Ukucocwa kweoyile | Iityhubhu zesithando somlilo eziqhekekayo, imibhobho yereactor, izinto zokutshintsha ubushushu, imigca yezixhobo | Imelana nobushushu obufikelela kwi-600°C, imelana nokuqhekeka kwehydrogen kunye nokubola kwesulfure |
| Ishishini lePetrochemical | Imibhobho yenkqubo yobushushu obuphezulu, izixhobo zangaphakathi, iinxalenye zepompo | Ukuchatshazelwa ixesha elide kubushushu obuphezulu kunye noxinzelelo oluphezulu |
| Ukuveliswa koMbane | Iityhubhu zebhoyila ezinoxinzelelo oluphezulu, iindawo zokuvuselela i-heater | Iyamelana noxinzelelo olungaphezulu kwe-10 MPa |
| Inkonzo yobushushu obuphezulu ngokubanzi | Ukusebenza okuqhubekayo ngaphezulu kwama-500°C | Uzinzo lwexesha elide kumaqondo obushushu aphezulu |
Ubushushu obuphezulu obucetyiswayo buyi-600°C. Kwii-oven eziqhekekayo ze-refinery, ukumelana kwayo nohlaselo lwe-hydrogen kunye nokugqwala kwesalfure kwandisa ubomi bezixhobo.
5. Amanqaku alinganayo kumazwe ngamazwe
I-15Х5М ihambelana nemigangatho eyahlukeneyo yamazwe ngamazwe, iququzelela ukufunwa kunye nokutshintshwa kwehlabathi:
| Inkqubo esemgangathweni | Ibanga elilinganayo |
|---|---|
| ITshayina (GB) | 12Cr5Mo (uphawu olutsha) / 1Cr5Mo (endala) |
| I-USA (ASTM/ASME) | A335 P5(ipayipi) / SA387 Gr.5 (ipleyiti) / A182 F5 (izinto zokugquma) |
| iYurophu (EN) | X12CrMo5 (inombolo yezinto ezibonakalayo 1.7362) |
| IJapan (JIS) | I-STBA25 |
Inqaku lokuthengwa: I-15Х5М ngokweekhemikhali nangoomatshini isondele kakhulu kwi-GB/T 9948 yaseTshayina yebanga le-12Cr5Mo. Iifektri zaseTshayina zasekhaya zinokuvelisa ngokweemfuno zaseRashiya, kwaye isiqinisekiso sezinto ezibonakalayo sinokudwelisa zombini iibakala ezilinganayo ze-GOST kunye ne-GB/ASME xa ziceliwe.
6. Inkqubo yoMveliso kunye noQinisekiso loMgangatho
Iipayipi ezingenamthungo ze-15Х5М ziveliswa ngale nkqubo ilandelayo:
Ukubhoboza okushushu: Iibhilethi ezingqukuva zifudunyezwa ukuya kuthi ga kwi-1200‑1300°C, emva koko zibhobozwa ngesixhobo sokubhoboza esijikelezayo ukuze zenze amaqokobhe angenanto.
Ukuqengqeleka okuqhubekayo: Ukusebenzisa i-retained mandrel continuous rolling mill ukuze kuphuculwe ukufana kobukhulu bodonga, kunye nokunyamezela kwe-OD kulawulwa ngaphakathi kwe-±0.5%.
Unyango lobushushu: Ukulungisa (900‑950°C) + Ukufudumala (650‑700°C) – kususa uxinzelelo olushiyekileyo kwaye kuphucule isakhiwo seenkozo.
Uvavanyo olungonakalisiyo: Uvavanyo lwe-Ultrasonic (UT) kunye novavanyo lwe-eddy current (ET) ziqinisekisa ukuba akukho ziphene zangaphakathi.
Iziqinisekiso zomgangatho:
Ibhetshi nganye iza neSatifikethi soVavanyo lweMill (MTC) esipheleleyo.
Singabonelela ngeesatifikethi ze-EN 10204 Type 3.1 okanye 3.2.
Ukuhlolwa kweqela lesithathu yi-SGS, BV, TÜV kuyaxhaswa.
Ukulandeleka ngokupheleleyo ukusuka kwinani lobushushu ukuya kwimveliso egqityiweyo.
7. Irhafu yeKhabhoni ye-EU CBAM – Khetha iSanon ukuze unciphise iindleko zokuthobela imithetho
Ukusukela nge-1 kaJanuwari 2026, i-EU Carbon Border Adjustment Mechanism (CBAM) iyasebenza ngokupheleleyo, kwaye icandelo lesinyithi lilokuqala kumgca. Ukuba awukwazi ukubonelela ngedatha yokwenyani yokukhupha umbane eqinisekisiweyo, i-EU iya kusebenzisa amaxabiso asisiseko - ngokusekelwe kumndilili wamazwe ali-10 akhupha umbane kakhulu kwihlabathi liphela - oko kuthetha ukuba iindleko zerhafu yekhabhoni ziphezulu kakhulu.
I-Sanon Pipe Industry isebenzisana ne-TÜV NORD ukunceda iifektri zilungiselele ukuthobela imithetho ye-CBAM:
Idatha elinganiswe ngokwenene: Singabonelela ngedatha yokukhupha ikhabhoni ethile kwimveliso ngokusekelwe kumlinganiselo wesiza, ukukunceda uphephe amaxabiso amiselweyo esohlwayo.
Ukulandeleka ngokupheleleyo: Iingxelo ezipheleleyo zokukhupha ukungcola ukusuka ekuthathweni kwezinto eziluhlaza ukuya ekuthunyelweni kwemveliso egqityiweyo.
Inkonzo yokuthobela umthetho kwindawo enye: Uncedo ngezicwangciso zokubeka esweni, iingxelo zokukhupha ukungcola, iisampulu zedatha, kunye namaxwebhu ophicotho-zincwadi aphambili ali-9.
Ukukhetha iSanon akuthethi nje kuphela imibhobho yentsimbi ekumgangatho ophezulu, kodwa ikwaliqabane eliqinileyo lokulandela imigaqo yekhabhoni ye-EU CBAM ngokuzithemba.
