Umbhobho wentsimbi engenamthungo we-alloy ye-A335P92, iinkcukacha ezingama-48.3*7.14 (oko kukuthi, ububanzi bangaphandle yi-48.3mm, ubukhulu bodonga yi-7.14mm), njengombhobho webhoyila oxinzelelweyo, umgangatho wokusetyenziswa kwawo yi-ASTM A335M. Oku kulandelayo luhlalutyo oluneenkcukacha lombhobho wentsimbi:
I. Isishwankathelo esisisiseko seetyhubhu zebhoyila zentsimbi
Umbhobho wentsimbi engenamthungo we-A335P92 alloy luhlobo lombhobho wentsimbi engenamthungo we-alloy enobushushu obuphezulu kunye noxinzelelo oluphezulu, osetyenziswa kakhulu kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu ezifana nombhobho ophambili womphunga kunye nombhobho womphunga ofudunyezwayo wezityalo zamandla obushushu. Izinto zayo yi-P92, eyiyeyentsimbi ye-ASTM A335 P92 martensitic enganyangekiyo kubushushu e-United States.
Okwesibini, ukwakheka kweekhemikhali zeSteel Boiler Tubes
Ulwakhiwo lweekhemikhali ze-A335P92 alloy steel pipe seamless lulawulwa ngokuchanekileyo, ikakhulu luquka ikhabhoni, i-manganese, i-phosphorus, i-sulfur, i-silicon, i-chromium, i-molybdenum, i-vanadium, i-nitrogen, i-nickel, i-aluminium, i-niobium, i-tungsten kunye ne-boron kunye nezinye izinto. Uluhlu oluthile lomxholo lulandelayo:
Ikhabhoni (C): 0.07~0.13%
IManganese (Mn): 0.30-0.60%
I-Phosphorus (P): ≤0.020%
I-Sulfur (S): ≤0.010%
I-Silicon (Si): ≤0.50%
I-Chromium (Cr): 8.5~9.50%
I-Molybdenum (Mo): 0.30~0.60% (kodwa kubalulekile ukuqaphela ukuba xa ithelekiswa nentsimbi ye-SA-335P91, intsimbi ye-SA-335P92 inciphisa ngokufanelekileyo umxholo we-Mo element, kwaye iphucula ukusebenza kwezinto ngokongeza ubungakanani obuthile be-W)
I-Vanadium (V): 0.15~0.25%
I-nitrogen (N): 0.03~0.07%
I-Nickel (Ni): ≤0.40%
I-Aluminiyam (Al): ≤0.04%
I-Niobium (Nb): ≤0.040~0.09%
I-Tungsten (W): 1.5~2.0%
IBoron (B): 0.001~0.006%
Umlinganiselo ofanelekileyo wezi zinto wenza ukuba umbhobho wentsimbi engenamthungo we-A335P92 alloy ube nokumelana nokugqwala okugqwesileyo kobushushu obuphezulu, ukumelana nokuxinana, amandla obushushu aphezulu kunye neempawu zokurhubuluza.
3. Iimpawu zoomatshini zeetyhubhu zeBoiler zeNtsimbi
Umbhobho wentsimbi engenamthungo we-A335P92 alloy uneempawu ezintle kakhulu zoomatshini, eziboniswe ngolu hlobo lulandelayo:
Amandla okutsalwa: ≥620MPa
Amandla okuvelisa: ≥440MP
Ezi mpawu zoomatshini ziqinisekisa ukhuseleko kunye nokuthembeka kweetyhubhu zentsimbi kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.
4. Indawo yokusetyenziswa kweetyhubhu zebhoyila zentsimbi
Umbhobho wentsimbi engenamthungo we-A335P92 alloy ngenxa yeempawu zayo zokusebenza ezigqwesileyo, usetyenziswa kakhulu kwezi ndawo zilandelayo:
Isikhululo samandla obushushu: njengesixhobo esibalulekileyo sombhobho ophambili womphunga kunye nombhobho womphunga ofudunyezwayo, sinokumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu ukuqinisekisa ukusebenza ngokukhuselekileyo kwesikhululo samandla.
I-Petrochemical: Kwinkqubo yokucoca i-petroleum kunye nokuveliswa kweekhemikhali, isetyenziselwa ukuvelisa izixhobo ezifana nee-reactors, ii-heat exchangers kunye neepayipi zokuhambisa ukuze kuhlangatyezwane neemfuno zobushushu obuphezulu kunye noxinzelelo kunye nokumelana nokugqwala.
Ishishini lamandla enyukliya: Kwizikhululo zamandla enyukliya, lisetyenziselwa ukuvelisa iinkqubo zokupholisa izixhobo zenyukliya kunye nemibhobho enxulumene noko ukuqinisekisa ukhuseleko kunye nokuzinza kokuveliswa kwamandla enyukliya.
5. Imigangatho yokusetyenziswa kunye nemiyalelo yoku-odola iiTyhibhi zeBoiler zeNtsimbi
Umbhobho wentsimbi engenamthungo we-alloy ye-A335P92 uhambelana nomgangatho ophezulu we-ASTM A335/A335M. Xa u-odola, ulwazi olulandelayo kufuneka lucace:
Ubungakanani (umz. ngeenyawo, ngeemitha, okanye ingcambu)
Igama lezinto (umbhobho oqhelekileyo wentsimbi engenamthungo)
Iklasi (P92)
Indlela yokuvelisa (ukugqiba okushushu okanye umzobo obandayo)
Iinkcukacha (umz. ububanzi bangaphandle, ubukhulu bodonga, njl.njl.)
Ubude (ubungakanani obahlulwe kunye nobukhulu obuguquguqukayo)
Ukuphela komatshini wokulungisa
Iimfuneko zokukhetha (umz. uxinzelelo lwamanzi kunye nokuphambuka kobunzima obuvumelekileyo)
Ingxelo yovavanyo efunekayo
Inombolo eqhelekileyo
Iimfuno ezikhethekileyo okanye naziphi na iimfuno ezongezelelweyo ezinganyanzelekanga
Ngamafutshane, umbhobho wentsimbi engenamthungo we-A335P92 yipayipi yentsimbi engenamthungo ekumgangatho ophezulu enobushushu obuphezulu kunye noxinzelelo oluphezulu, esetyenziswa kakhulu kwiindawo ezininzi ezineempawu zayo zokusebenza ezigqwesileyo. Xa u-odola kwaye usebenzisa, kuyimfuneko ukuthobela ngokungqongqo imigangatho kunye neemfuno ezifanelekileyo ukuqinisekisa ukhuseleko kunye nokuthembeka kwayo.
Wamkelekile ukuba unxibelelane nathi ukuze ufumane iinkcukacha ezithe vetshe!
