Ipip yentsimbi engenamthungoU-e ngumcu wentsimbi omde onomngxuma onqamlezileyo kwaye akukho zithungo zijikelezileyo. Ngenxa yobubodwa benkqubo yokuvelisa, inamandla amakhulu kunye nokumelana noxinzelelo oluhle. Imibhobho yentsimbi engenamthungo eyaziswa ngeli xesha ibandakanya izinto ezimbini kunye neenkcukacha: ibakala le-15CrMoG, inkcazo ye-325 × 14 kunye12Cr1MoVGibakala, iinkcukacha 325×10.

Iimpawu kunye nokusetyenziswa kwe15CrMoGumbhobho wentsimbi
I-15CrMoG yintsimbi ye-chromium-molybdenum alloy, iinqununu eziphambili zeekhemikhali ezibandakanya i-carbon (C), i-chromium (Cr), i-molybdenum (Mo), njl. Le nto inamandla amakhulu, ukumelana ne-oxidation efanelekileyo kunye nokumelana nokushisa okuphezulu, ngokukodwa kwiqondo lokushisa eliphezulu kunye neendawo zoxinzelelo oluphezulu. Ukongeza, i-15CrMoG nayo inokusebenza kakuhle kwe-welding kunye nokuqhubekeka.

Usebenzisa
Imibhobho yentsimbi engenamthungo eyenziwe nge-15CrMoG isetyenziswa ikakhulu kubushushu obuphezulu kunye nemibhobho yoxinzelelo oluphezulu kunye nezixhobo, kwaye isetyenziswa ngokubanzi kule mimandla ilandelayo:

Umzi-mveliso wamandla: izifudumezi ezinkulu zebhoyila, izifudumezi, iiheader kunye nemibhobho ephambili yomphunga kwizityalo zamandla obushushu.
Ishishini lemichiza: iinkqubo zemibhobho yeereactor zobushushu obuphezulu kwizixhobo zekhemikhali.
Ishishini lePetroleum: imibhobho yobushushu obuphezulu kunye nabatshintshisi bobushushu kwiindawo zokucokisa.
Lo mbhobho wentsimbi unokugcina iimpawu ezibalaseleyo zoomatshini kumaqondo obushushu aphezulu, kwaye ifaneleke ngokukodwa ubushushu bokusebenza bexesha elide phakathi kwe-500 ° C kunye ne-580 ° C.
Iimpawu kunye nokusetyenziswa kwemibhobho yentsimbi ye-12Cr1MoVG
I-12Cr1MoVG yintsimbi ekumgangatho ophezulu we-chromium-molybdenum-vanadium ephawulwe ngamandla aphezulu, ukuxhathisa okuhle kokukhasa, kunye nokugqwala okuqinileyo kunye nokumelana ne-oxidation. Xa kuthelekiswa ne-15CrMoG, yongeza inani elincinci le-vanadium (V), eliphucula ngakumbi ukuchasana nokushisa okuphezulu kunye nokuzinza.
Usebenzisa
Imibhobho yentsimbi engenamthungo eyenziwe nge-12Cr1MoVG ihlala isetyenziswa kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye uluhlu lwezicelo zabo lubandakanya:
Indawo yamandla: izifudumezi ezinobushushu obuphezulu, izifudumezi kwakhona kunye nemibhobho kwizityalo zamandla obushushu kunye nezixhobo zamandla enyukliya.
Ishishini lePetrochemical: izixhobo zekhemikhali ezinobushushu obuphezulu kunye noxinzelelo oluphezulu kunye nemibhobho.
Ukuveliswa kwebhoyila: ukuvelisa iityhubhu zebhoyila ezinoxinzelelo oluphezulu lwezixhobo ezinoxinzelelo oluphezulu lokusebenza.
Olu hlobo lombhobho wensimbi lufanelekile ukusetyenziswa ixesha elide kumaqondo okushisa asebenzayo angaphezu kwama-570 ° C kwaye unokumelana nokunyuka okunamandla kunye ne-ductility.
Umbhobho wensimbi we-15CrMoG kunye ne-specification ye-325 × 14 kunye ne-12Cr1MoVG ipayipi yensimbi kunye ne-specification ye-325 × 10 igxininise. Zomibini ziyimibhobho yensimbi engenamthungo ephezulu kwaye isetyenziswa ngokubanzi kumashishini aphezulu kunye noxinzelelo oluphezulu njengamandla, iikhemikhali zepetroli kunye neekhemikhali. Ngokuxhomekeke kwimeko yokusetyenziswa, abasebenzisi banokukhetha into efanelekileyo kakhulu yombhobho wentsimbi ukuhlangabezana neemfuno zemveliso.
