Xa uthengaUmbhobho wentsimbi ye-ASTM A335 engenamthungoKwizityalo zamandla, kwiindawo zokucoca okanye kwiinkqubo zemibhobho ezinobushushu obuphezulu, abathengi badla ngokudibana neempawu ezahlukeneyo zezinto ezisetyenziswayo kwiinkcukacha zaseMelika, zaseTshayina, zaseYurophu naseRashiya.
Iprojekthi ingachazaI-ASTM A335 P11okanye i-P22, ngelixa umthengisi wasekuhlaleni enokucaphula15CrMo, 15ХМ, 10CrMo5-5 okanye 10Х2МEkuqaleni, la manqanaba anokubonakala etshintshana kuba akwiintsapho zentsimbi ye-chromium-molybdenum alloy ezifanayo.
Nangona kunjalo,ukwakheka kweekhemikhali ezifanayo akuthethi ngokuzenzekelayo ukuba kukho iimfuno zobugcisa ezifanayo.
Ngokuphathelele ukuthengwa kwempahla kumazwe ngamazwe, umbuzo obalulekileyo awungowokuba “Ngowuphi umgangatho olingana nawo?” kodwa ngumbuzo wokuba ingaba izinto ezicetywayo ziyayanelisa na iprojekthi.umgangatho, ukwakheka kweekhemikhali, iipropati zoomatshini, unyango lobushushu, uvavanyo kunye neemfuno zoyilo.
Yintoni i-ASTM A335?
I-ASTM A335/A335Myinkcazo yeumbhobho we-ferritic alloy-steel ongenamthungo wenkonzo yobushushu obuphezuluUluhlu lwangoku lwe-ASTM luchonga i-A335/A335M-26 njengohlelo olusebenzayo. Inkcazo igubungela amanqanaba ahlukeneyo e-ferritic alloy-steel, kuqukaP11 kunye neP22, kwaye ibandakanya iimfuno ezinxulumene nokwakheka kweekhemikhali, iimpawu zoomatshini, ubulukhuni, uvavanyo lwe-hydrostatic kunye novavanyo olungonakalisiyo.
Ukukhetha phakathi kwe-P11, i-P22 kunye nezinye iiklasi kuxhomekeke kwiimeko zenkonzo yokwenyani kunye neemfuno zeprojekthi endaweni yegama lebakala lodwa.
Kubathengi, amabini awona manqaku athethwa kakhulu ngala:
●I-ASTM A335 P11 — malunga nenkqubo ye-alloy ye-1.25Cr-0.5Mo
●I-ASTM A335 P22 — malunga nenkqubo ye-alloy ye-2.25Cr-1Mo
Amanqanaba aphezulu e-chromium kunye ne-molybdenum e-P22 ayinika iprofayili yokusebenza kobushushu obuphezulu eyahlukileyo kune-P11. Iimfuno zeekhemikhali ze-ASTM zidwelisa malunga ne-1.00–1.50% Cr kunye ne-0.44–0.65% Mo ye-P11, kwaye malunga ne-1.90–2.60% Cr kunye ne-0.87–1.13% Mo ye-P22.
I-ASTM A335 P11 xa ithelekiswa ne-15CrMo / 15ХМ
I-ASTM A335 P11isetyenziswa kakhulu kwiipayipi ezishushu kakhulu kunye nezixhobo ezihambelanayo zobushushu.
Kwiitheyibhile zamazwe ngamazwe zokuthelekisa izinto, i-P11 idla ngokunxulunyaniswa1.25Cr-0.5Mousapho, kuquka10CrMo5-5kunye nesiTshayina15CrMoEzinye iireferensi. Abanye abathengisi kunye neemarike basebenzisa iireferensi ezisetyenziswa eRashiya ezifana15ХМ, kodwa umgangatho ochanekileyo waseRashiya kunye nomgangatho wemveliso kufuneka uqinisekiswe rhoqo ngokuchasene nenkcazo yeprojekthi.
Ingongoma esebenzayo kubathengi kukuba igama linokutshintsha ukusuka kwenye imarike ukuya kwenye ngelixa usapho lwe-alloy olusisiseko lunokufana.
| Uyilo lwezinto | Usapho oluqhelekileyo lwezinto eziphathekayo | Umxholo wokuthengwa kwempahla oqhelekileyo |
| I-ASTM A335 P11 | Intsimbi ye-Cr-Mo alloy | Umbhobho ongenamthungo obushushu obuphezulu |
| 15CrMo | Intsimbi ye-Cr-Mo alloy | Izicelo zoshishino/zobushushu zaseTshayina |
| 10CrMo5-5 | Intsimbi ye-Cr-Mo alloy | Isalathiso sezinto zaseYurophu |
| 15ХМ | Intsimbi ye-Cr-Mo alloy | Isalathiso semarike yaseRashiya/yeCIS |
Itafile kufuneka isetyenziswe njengeindawo yokuqala yokuthelekisa, hayi njengetafile yokutshintsha ngokuzenzekelayoUkhetho lokugqibela lwezinto ezisetyenzisiweyo kufuneka lulandele umgangatho ofanelekileyo kunye neenkcukacha zeprojekthi.
Umzekelo, umthengi oodolaUmbhobho ongenamthungo we-ASTM A335 P11akufuneki nje ithathe indawo yayo nge-15CrMo kuba umxube weekhemikhali ujongeka usondele. Umthengisi kufuneka aqinisekise iimfuno ezipheleleyo, kubandakanya uhlobo lwemveliso, unyango lobushushu, iimpawu zoomatshini, uvavanyo kunye namaxwebhu.
I-P22 vs 10CrMo5-5 / 10Х2М: Kutheni uthelekiso lufuna ukhathalelo
Uthelekiso lwesibini lufuna ingqalelo engakumbi.
I-ASTM A335 P22yeyamalunga2.25Cr-1Mousapho. Iingxelo zaseYurophu eziqhele ukunxulunyaniswa nolu sapho ziquka10CrMo9-10 / 10CrMo910, ngelixa10Х2Мikwafumaneka nakwiingxoxo zezinto zaseRashiya/zeCIS.
Ngokuphikisana,I-10CrMo5-5 idla ngokunxulunyaniswa nosapho lwe-1.25Cr-0.5Mo oluphantsi kwaye idla ngokubhekiselelwa kwi-A335 P11., endaweni ye-P22.
Lo mahluko ubalulekile xa isebe lokuthenga lifumana iikowuteshini ezivela kumazwe ahlukeneyo.
Imbono elula yezinto eziphathekayo kunye nosapho yile:
| Ibanga le-ASTM | Usapho lwe-alloy oluqikelelweyo | Iingxelo eziqhelekileyo zamazwe ngamazwe |
| A335 P11 | 1.25Cr-0.5Mo | 15CrMo/ Usapho lwe-10CrMo5-5 |
| A335 P22 | 2.25Cr-1Mo | 10CrMo9-10 / 10CrMo910 / iireferensi ezikhethiweyo ze-10Х2М |
Ke ngoko, ukuba inkcazo yeprojekthi ifunaI-ASTM A335 P22, isicatshulwa se-10CrMo5-5 kufunekahayiyamkelwe njengexabiso elilinganayo ngaphandle kophononongo lobugcisa.
Kulapho kanye apho amava okufumana ulwazi kwamanye amazwe ebaluleke khona:Inombolo yezinto ezisetyenzisiweyo, umgangatho wemveliso kunye nokusetyenziswa kweprojekthi maziqwalaselwe kunye.
Kutheni Abathengi Bethelekisa La Mabanga?
Isizathu sicacile: iiprojekthi zamazwe ngamazwe zihlala ziquka imigangatho eliqela ngaxeshanye.
Isityalo samandla singasebenzisa:
●I-ASTM A335 P11/P22 yeepayipi zobushushu obuphezulu
●I-ASTM A213 T11/T22 yeetyhubhu zebhoyila kunye nezokutshintsha ubushushu
●Ipleyiti yentsimbi ye-ASTM A387 Cr-Mo yeenqanawa zoxinzelelo
●Iityhubhu zentsimbi ze-alloy ze-EN 10216-2
●Amanqanaba e-GB/T kwizixhobo ezifumaneka apha ekhaya
●Izixhobo zeGOST okanye zesiRashiya ezichaza iiprojekthi zeCIS
Kwikontrakta ye-EPC, ukutshintsha enye into ngeyinye kunokuchaphazela oku kulandelayo:
Uyilo → Ukuwelda → Unyango lobushushu → Uhlolo → Amaxwebhu → Ukuvunywa
Ngoko ke, uthelekiso lwamanqaku kufuneka lwenziwe ngaphambi kokuba kuthengwe, kungekhona emva kokuba izinto sele zi-odolwe.
P11 okanye P22: Ngowuphi udidi ekufuneka abathengi balucacise?
Impendulo ixhomekeke kwiimeko zokusebenza zokwenyani.
P11ngokubanzi kuqwalaselwa xa iprojekthi ifuna intsimbi ye-Cr-Mo ene-alloy ephantsi efanelekileyo kwinkonzo yobushushu obuphezulu.
P22inika inqanaba eliphezulu le-Cr-Mo alloy kwaye isetyenziswa kwizicelo apho iinkcukacha zeprojekthi zifuna izinto ezihambelanayo kunye nokusebenza kobushushu obuphezulu.
Iindawo eziqhelekileyo zokusetyenziswa ziquka:
| Isicelo | Imizekelo yezinto eziphathekayo |
| Iinkqubo zomphunga zebhoyila kunye nezoncedo | I-P11 / amanqanaba anxulumene ne-Cr-Mo |
| Imibhobho yomphunga enobushushu obuphezulu | P11 / P22 kuxhomekeke kuyilo |
| Iintloko zezityalo zamandla | P11 / P22 / amanye amabakala achaziweyo |
| Imibhobho yenkqubo yokucoca | P11 / P22 kuxhomekeke kwinkonzo |
| Imibhobho yobushushu obuphezulu bePetrochemical | I-P22 kunye nezinye iiklasi ze-Cr-Mo |
| Izixhobo zoxinzelelo | Izinto zeCr-Mo ezijoliswe kwiprojekthi ethile |
Umgangatho ochanekileyo kufuneka ukhethwe kwiubushushu boyilo, uxinzelelo, uxinzelelo oluvumelekileyo, imeko-bume yenkonzo kunye nekhowudi yoyilo efanelekileyo, endaweni yokuthelekisa amaxabiso ezinto kuphela.
I-ASTM A335 P11 kunye ne-P22 azifani ne-ASTM A213 T11 kunye ne-T22
Enye ingxaki eqhelekileyo yokuthenga iyadidaamanqanaba epayipikunyeamanqanaba etyhubhu.
Umzekelo:
●I-ASTM A335 P11 → umbhobho wentsimbi engenamthungo wenkonzo yobushushu obuphezulu
●I-ASTM A213 T11 → ibhoyila engenamthungo, i-superheater kunye netyhubhu yokutshintshiselana nobushushu
●I-ASTM A335 P22 → umbhobho wentsimbi engenamthungo
●I-ASTM A213 T22 → imveliso yetyhubhu yezicelo ezigutyungelwe yi-A213
Amagama e-P11/T11 kunye ne-P22/T22 anxulumene nosapho lwe-Cr-Mo alloy, kodwa imigangatho yemveliso yahlukile.
Lo mahluko ubalulekile xa ulungiselela iodolo yokuthenga, kubaumgangatho + umgangatho wemveliso + ubungakanani + iimfuno zovavanyoZonke kufuneka zihambelane nenkcazo yeprojekthi.
Yintoni Abathengi Abafanele Bayihlole Ngaphambi Kokuba Bayi-odole?
Xa uthengaUmbhobho we-ASTM A335 P11 or Umbhobho we-ASTM A335 P22, umbuzo omfutshane ofana nothi “P11 pipe, nceda ucaphule” usenokunganelanga.
Ukuze ufumane ikowuteshini echanekileyo, abathengi kufuneka banikezele:
1. Umgangatho wemveliso — ASTM A335/A335M
2. Ibanga — P11, P22, njl.
3. Ubungakanani bombhobho — NPS okanye OD × ubukhulu bodonga

Ngaphambi kokuba utshintshe iBanga elinye ngelinye, buza le mibuzo
Xa umthengi ecelaI-15CrMo endaweni ye-A335 P11, okanye iklasi ye-Cr-Mo yesiRashiya/yaseYurophu endaweni yeA335 P22, le mibuzo ilandelayo kufuneka iphendulwe kuqala:
Ingaba umgangatho wemveliso uyamkeleka?
Ingaba ukwakheka kweekhemikhali kuyahlangabezana neemfuno ezifunekayo?
Ngaba iipropati zoomatshini ziyahlangabezana neemfuno zeprojekthi?
Ingaba imeko yonyango lobushushu iyamkeleka?
Ngaba iimfuno zovavanyo kunye ne-NDE ziyalingana?
Ngaba ezi zinto ziya kwamkelwa ngumthengisi we-EPC okanye ngumsebenzisi wokugqibela?
Ngaba umthengisi angabonelela nge-MTC efunekayo kunye nokulandeleka kwayo?
Kuphela emva kokuba la manqaku eqinisekisiwe apho kuya kuqwalaselwa into esemgangathweni ongaphezulu ukuze itshintshwe.
