Ipayipi yentsimbi engenamthungoI-e ngumcu omde wentsimbi onecandelo elingenanto kwaye akukho mithungo ijikelezileyo. Ngenxa yokwahluka kwenkqubo yayo yokwenziwa, inamandla aphezulu kwaye inokumelana kakuhle noxinzelelo. Imibhobho yentsimbi engenamthungo engeniswe ngeli xesha ibandakanya izixhobo ezimbini kunye neenkcukacha: i-15CrMoG grade, iinkcukacha ezingama-325×14 kunye12Cr1MoVGibakala, iinkcukacha 325×10.

Iimpawu kunye nokusetyenziswa kwe15CrMoGumbhobho wentsimbi
I-15CrMoG yintsimbi ye-chromium-molybdenum alloy, iindawo eziphambili zeekhemikhali eziquka ikhabhoni (C), i-chromium (Cr), i-molybdenum (Mo), njl. Le nto inamandla aphezulu, iyakwazi ukumelana ne-oxidation kwaye ikwazi ukumelana nobushushu obuphezulu, ingakumbi kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu. Ukongeza, i-15CrMoG ikwanayo nokusebenza kakuhle kwe-welding kunye nokuqhubekeka kwayo.

Ukusetyenziswa
Iipayipi zentsimbi ezingenamthungo ezenziwe nge-15CrMoG zisetyenziselwa ikakhulu iipayipi nezixhobo zobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye zisetyenziswa kakhulu kwezi ndawo zilandelayo:

Ishishini lamandla: ii-boiler superheaters, ii-reheaters, ii-headers kunye nemibhobho ephambili yomphunga kwizityalo zamandla ezishushu.
Ishishini leekhemikhali: iinkqubo zemibhobho yee-reactors ezinobushushu obuphezulu kwizixhobo zeekhemikhali.
Ishishini lepetroleum: imibhobho enobushushu obuphezulu kunye nezixhobo zokutshintshiselana ubushushu kwiindawo zokucocisa.
Le pipe yentsimbi inokugcina iipropati ezintle kakhulu zoomatshini kumaqondo obushushu aphezulu, kwaye ifanelekile ngokukodwa kumaqondo obushushu okusebenza ixesha elide phakathi kwama-500°C nama-580°C.
Iimpawu kunye nokusetyenziswa kwemibhobho yentsimbi ye-12Cr1MoVG
I-12Cr1MoVG yintsimbi ye-chromium-molybdenum-vanadium ekumgangatho ophezulu ephawulwa ngamandla aphezulu, ukumelana okuhle nokuqhekeka, kunye nokumelana okunamandla kokugqwala kunye ne-oxidation. Xa ithelekiswa ne-15CrMoG, yongeza inani elincinci le-vanadium (V), eliphucula ngakumbi ukumelana kwayo nokuqina kobushushu obuphezulu.
Ukusetyenziswa
Iipayipi zentsimbi ezingenamthungo ezenziwe nge-12Cr1MoVG zihlala zisetyenziswa kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye uluhlu lwazo lokusetyenziswa luquka:
Intsimi yamandla: ii-superheaters ezishushu kakhulu, ii-reheaters kunye nemibhobho kwizityalo zamandla ezishushu kunye nezityalo zamandla enyukliya.
Ishishini le-Petrochemical: izixhobo zeekhemikhali kunye nemibhobho eshushu kakhulu nexinezelekileyo.
Ukwenziwa kwebhoyila: ukuvelisa iityhubhu zebhoyila ezinoxinzelelo oluphezulu kwizixhobo ezinoxinzelelo oluphezulu lokusebenza.
Olu hlobo lombhobho wentsimbi lufanelekile ukusetyenziswa ixesha elide kumaqondo obushushu asebenzayo angaphezulu kwama-570°C kwaye lunamandla amakhulu okumelana nokuqhekeka kunye nokuguquguquka.
Umbhobho wentsimbi we-15CrMoG onengcaciso ye-325×14 kunye nombhobho wentsimbi we-12Cr1MoVG onengcaciso ye-325×10 zigxile kuzo. Zombini ziipayipi zentsimbi ezingenamthungo ezisebenza kakhulu kwaye zisetyenziswa kakhulu kumashishini anobushushu obuphezulu kunye noxinzelelo oluphezulu njengamandla, iikhemikhali zepetroli, kunye neekhemikhali. Ngokuxhomekeke kwindawo yokusetyenziswa, abasebenzisi banokukhetha izixhobo zombhobho wentsimbi ezifanelekileyo ukuhlangabezana neemfuno zemveliso.
