Disemba 2025 - Uphuhliso oluPhambili lweShishini kunye noHlaziyo lweMigaqo-nkqubo
Njengoko u-2025 uphela, imakethi yehlabathi yemibhobho yentsimbi engenamthungo ijongene notshintsho olukhulu ngemigaqo-nkqubo emitsha yelayisenisi yokuthumela ngaphandle elindelweyo evela kumagunya aseTshayina. Abahlalutyi bemarike babonisa ukuba le mithetho, enokwenzeka ukuba iqale ukusebenza ekuqaleni kuka-2026, iya kufuna amaxwebhu aphuculweyo okuthunyelwa kwamanye amazwe kwemibhobho yentsimbi yekhabhoni, imibhobho yentsimbi ye-alloy, kunye nemibhobho yentsimbi engenamthungo engenamthungo. Lo mgaqo-nkqubo ujolise ekumiseni ulawulo lomgangatho kulo lonke ilizwe.I-API 5L, I-ASTM A106, I-ASTM A335 P11/P22, kunye neendidi zeemveliso ze-ASTM A312 TP304/TP316L ngelixa zijongana neenkxalabo zorhwebo lwamazwe ngamazwe.
Iinguqu zeMarike kaDisemba kunye neeNdlela zokuphela konyaka
Iimeko zemarike zangoku zibonisa uzinzo emva kohlengahlengiso lukaNovemba, kunye nokwehla kwezitokhwe zemibhobho engenamthungo malunga ne-8.2% kwiindawo ezinkulu zemveliso zaseTshayina. Icandelo lemibhobho yeoyile negesi ligcina imfuno ezinzileyo yemibhobho yomgca kunye neemveliso ze-OCTG, ngelixa iiprojekthi zokuvelisa umbane ziqhubeka nokufuna iityhubhu zebhoyila ezinoxinzelelo oluphezulu kunye neetyhubhu zokutshintsha ubushushu. Nangona kunjalo, abaphathi bokuthenga baxela amaxesha okonga angaphezulu eentsuku ezingama-50-65 zemibhobho engenamthungo enobubanzi obukhulu kunye neepayipi zentsimbi ye-alloy ekhethekileyo njengoko iifektri zigqibezela iiodolo ezikhoyo ngaphambi kotshintsho olunokwenzeka lomgaqo-nkqubo.
Impembelelo elindelweyo yoMgaqo-nkqubo kwiZixokelelwano zoNikezelo lweHlabathi

Isiphelo: Ucwangciso Olucwangcisiweyo Lotshintsho Lwemarike
Ukuphunyezwa kwelayisenisi yokuthumela ngaphandle okulindelweyo kubonisa iimfuno zokuthobela imithetho kunye namathuba okuqinisekisa umgangatho wokuthengwa kweepayipi zentsimbi. Ngokuseka iindlela zokubhala amaxwebhu ezicacileyo kunye nokuqinisa ubudlelwane nabathengisi ngoku, abathengi bamazwe ngamazwe banokulawula ngempumelelo utshintsho lomgaqo-nkqubo ngelixa befumana izibonelelo ezithembekileyo zeepayipi zentsimbi ezingenamthungo, iityhubhu zentsimbi yekhabhoni, kunye neepayipi ze-alloy ezikhethekileyo kwiiprojekthi zika-2026.
Nxibelelana neqela lethu lentengiso lamazwe ngamazwe ukuze ufumane uhlalutyo olucwangcisiweyo lwendlela olu phuhliso oluchaphazela ngayo iimfuno zakho ezithile zemibhobho engenamthungo, imibhobho edibeneyo, kunye neemveliso zetyhubhu. Sinikezela ngohlaziyo lwemarike, ukutolikwa komgaqo-nkqubo, kunye nophuhliso lwesicwangciso sokuthenga imibhobho yeoyile negesi, iinkqubo zokuvelisa umbane, kunye nokusetyenziswa kwemizi-mveliso.
I-ASTM A106 Gr.BUmbhobho wentsimbi engenamthungo ngumbhobho ongenamthungo wentsimbi yekhabhoni enobushushu obuphezulu kwi-American Society for Testing and Materials standard, edla ngokusetyenziselwa ukuthuthwa kolwelo phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu. Izixhobo ezihambelanayo eTshayina zibhekisa ikakhulu kwimigangatho yesizwe saseTshayina (GB) kunye nemigangatho yoshishino, kwaye kufuneka zihambelane kwiimbono ezintathu: ukwakheka kweekhemikhali, iimpawu zoomatshini, kunye neemeko zokusetyenziswa.
Ngokwesiqhelo kukho iindlela ezimbini zokuthelekisa izinto zasekhaya:
Izinto zokuqala ezihambelanayo: intsimbi engama-20 (GB/T 8163)
Intsimbi engama-20 yintsimbi eqhelekileyo yesakhiwo sekhabhoni, eyimpahla eqhelekileyo kumgangatho we-GB/T8163 kwaye ifanelekile ukuthuthwa kolwelo ngokubanzi. Uthelekiso lokwakheka kweekhemikhali: I-ASTM A106 Gr.B inomxholo wekhabhoni (C) oyi-0.17-0.24%, kunye ne-manganese (Mn) eyi-0.29-1.06%; Intsimbi engama-20 inomxholo wekhabhoni oyi-0.17-0.24%, kunye nomxholo we-manganese oyi-0.35-0.65%. Umxholo wekhabhoni wezi zimbini usondelelene, kodwa umxholo we-manganese we-ASTMA106 Gr.Binomda ophezulu ophezulu kunye nokusebenza ngcono kobushushu obuphezulu.
Uthelekiso lweempawu zoomatshini: I-ASTM A106 Gr.B inamandla okutsalwa kwe->415MPa kunye namandla okutsalwa kwe->240MPa; intsimbi engama-20 inamandla okutsalwa kwe->410MPa kunye namandla okutsalwa kwe->245MPa. Idatha iyafana kodwa amaqondo obushushu afanelekileyo ahlukile.
Imiqathango yokusetyenziswa: Intsimbi engama-20 ifanelekile kwiimeko zokusebenza ezinobushushu obungaphantsi kwama-350℃ kunye noxinzelelo oluphantsi. Ukuba isetyenziselwa ubushushu obuphezulu kunye noxinzelelo oluphezulu (njengemibhobho yebhoyila), kufuneka kukhethwe izinto ezisemgangathweni ophezulu.
Izinto zesibini ezihambelanayo: 20G (I-GB 5310)
I-20G yimbhobho yentsimbi engenamthungo yeebhoyila ezinoxinzelelo oluphezulu, ehambelana nomgangatho we-GB 5310 kwaye ifanelekile kwiinkqubo zomphunga ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.
Uthelekiso lokwakheka kweekhemikhali:20Ginomxholo wekhabhoni ongu-0.17-0.24%, umxholo we-manganese ongu-0.35-0.65%, kunye nolawulo oluqinileyo lomxholo we-phosphorus kunye ne-sulfur, ohambelana ngakumbi nezibonakaliso ze-ASTMA106 Gr.B.
Uthelekiso lweempawu zoomatshini: Amandla okutsalwa kwe-20G yi-≥410MPa, kwaye amandla ayo okuvelisa yi->245MPa, nto leyo efana kakhulu ne-ASTM A106 Gr.B, kwaye ubushushu obuvumelekileyo bokusebenza bufikelela kwi-450℃.
Iimeko zokusetyenziswa: I-20G isetyenziswa rhoqo kwimibhobho yebhoyila yezityalo zamandla obushushu kunye nezixhobo zoxinzelelo oluphezulu lweekhemikhali, kwaye ingathatha indawo ye-ASTM A106 Gr.B kwiimeko ezifanayo zokusebenza.
Amanyathelo okuthintela ukutshintshwa 1. Umahluko oqhelekileyo: I-ASTM A106 Gr.B ifuna uvavanyo lokutsalwa olunqamlezileyo kunye novavanyo lokuthamba, ngelixa i-GB/T 8163 ifuna uvavanyo lokutsalwa olude kuphela. Xa kutshintshwa, kuyimfuneko ukuqinisekisa ukuba izinto zovavanyo ziyahlangabezana neemfuno.
2. Iimfuno zonyango lobushushu: I-ASTM A106 Gr.B idla ngokuhanjiswa ikwimeko yokuqengqeleka okushushu, i-20G ifuna unyango oluqhelekileyo, kwaye inkqubo kufuneka ilungiswe ukuba itshintshwe.
3. Iimfuno zesatifikethi: Ukuba iprojekthi yokuthumela ngaphandle ichaza izinto ezisemgangathweni zaseMelika, kuyimfuneko ukuqinisekisa nomthengi ukuba ukutshintshwa komgangatho kazwelonke kuyamkelwa na. Ezinye iiprojekthi zinokufuna uhlolo olongezelelweyo lomntu wesithathu.
Ityala lesicelo esisebenzayo
Ishishini le-petrochemical lithenge imibhobho ye-ASTM A106 Gr.B yokuthutha ioyile kubushushu obuphezulu. Ngenxa yomjikelo omde wokuhambisa, yatshintshela kwizixhobo ze-20G. Emva kovavanyo lomntu wesithathu, ukuqina kwempembelelo (-20℃ KV2234J) kunye namandla obushushu obuphezulu (amandla okuvelisa>180MPa kwi-450℃) ye-20G yahlangabezana neemfuno zoyilo, kwaye iprojekthi yamkelwa.
Isishwankathelo
I-ASTM A106 Gr.B ingahambelana neentsimbi ezingama-20 (iimeko zokusebenza ngokubanzi) okanye i-20G (iimeko zokusebenza ezinobushushu obuphezulu kunye noxinzelelo oluphezulu) eTshayina. Xa kutshintshwa, kuyimfuneko ukudibanisa ubushushu obuthile, uxinzelelo kunye nemigangatho yovavanyo. Kucetyiswa ukuba kubekwe phambili izinto ezingama-20G, ezikhemikhali kunye nokusebenza kwazo kusondele kwiimfuno ezisemgangathweni zase-US kwaye zinoluhlu olubanzi lwezicelo.
