Ipayipi lensimbi elingenamthungo le-A335P92, imininingwane engu-48.3*7.14 (okungukuthi ububanzi bangaphandle bungu-48.3mm, ukujiya kodonga kungu-7.14mm), njengepayipi lebhoyila elinomfutho ophezulu, izinga layo lokusetshenziswa yi-ASTM A335M. Okulandelayo ukuhlaziywa okuningiliziwe kwepayipi lensimbi:
I. Ukubuka konke okuyisisekelo kwamapayipi ebhoyila ensimbi
Ipayipi lensimbi engenamthungo le-A335P92 uhlobo lwepayipi lensimbi engenamthungo lekhwalithi ephezulu lokushisa eliphezulu kanye ne-alloy enomfutho ophezulu, elisetshenziswa kabanzi ezindaweni ezishisa kakhulu kanye nezindawo ezishisayo ezifana nepayipi eliyinhloko lomusi kanye nepayipi lomusi elifudunyezwa kabusha lezitshalo zamandla ezishisayo. Izinto zalo ziyi-P92, ezingeyensimbi yensimbi yase-United States enenombolo ye-ASTM A335 P92 martensitic engashisi.
Okwesibili, ukwakheka kwamakhemikhali kwama-Steel Boiler Tubes
Ukwakheka kwamakhemikhali epayipi lensimbi engenamthungo ye-A335P92 kulawulwa ngokunembile, ikakhulukazi okuhlanganisa i-carbon, i-manganese, i-phosphorus, i-sulfur, i-silicon, i-chromium, i-molybdenum, i-vanadium, i-nitrogen, i-nickel, i-aluminium, i-niobium, i-tungsten ne-boron nezinye izinto. Uhlu lokuqukethwe oluthile lumi kanje:
Ikhabhoni (C): 0.07~0.13%
I-Manganese (Mn): 0.30-0.60%
I-Phosphorus (P): ≤0.020%
Isibabule (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 ukuthi uma iqhathaniswa nensimbi ye-SA-335P91, insimbi ye-SA-335P92 inciphisa ngokufanele okuqukethwe kwe-Mo element, futhi ithuthukisa ukusebenza kwezinto ngokungeza inani elithile le-W)
I-Vanadium (V): 0.15~0.25%
I-nitrogen (N): 0.03~0.07%
I-Nickel (Ni): ≤0.40%
I-Aluminium (Al): ≤0.04%
I-Niobium (Nb): ≤0.040~0.09%
I-Tungsten (W): 1.5~2.0%
I-Boron (B): 0.001~0.006%
Isilinganiso esifanele salezi zinto senza ipayipi lensimbi elingenamthungo le-A335P92 alloy libe nokumelana okuhle kakhulu nokugqwala kwezinga lokushisa eliphezulu, ukumelana nokugqwala, amandla okushisa aphezulu kanye nezakhiwo zokukhasa.
3. Izakhiwo zemishini zama-Steel Boiler Tubes
Ipayipi lensimbi elingenamthungo le-A335P92 linezici ezinhle kakhulu zemishini, eziboniswa kanje:
Amandla okudonsa: ≥620MPa
Amandla okukhiqiza: ≥440MP
Lezi zakhiwo zemishini ziqinisekisa ukuphepha nokuthembeka kwamapayipi ensimbi ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu.
4. Insimu yokusetshenziswa kwama-Steel Boiler Tubes
Ipayipi lensimbi elingenamthungo le-A335P92 ngenxa yezici zalo zokusebenza ezinhle kakhulu, lisetshenziswa kabanzi emikhakheni elandelayo:
Isitshalo sikagesi esishisayo: njengezinto ezibalulekile zepayipi eliyinhloko lomusi kanye nepayipi lomusi elifudunyezwa kabusha, singamelana nokushisa okuphezulu kanye nendawo enomfutho ophezulu ukuqinisekisa ukusebenza okuphephile kwesitshalo sikagesi.
I-Petrochemical: Enkambisweni yokuhluzwa kwephethiloli nokukhiqizwa kwamakhemikhali, isetshenziselwa ukukhiqiza imishini efana nama-reactor, ama-heat exchanger kanye namapayipi okudlulisa ukuze kuhlangatshezwane nezidingo zokushisa okuphezulu kanye nokumelana nokugqwala.
Imboni yamandla enuzi: Ezitshalweni zamandla enuzi, ezisetshenziswa ukukhiqiza izinhlelo zokupholisa ze-reactor yenuzi kanye namapayipi ahlobene ukuqinisekisa ukuphepha nokuzinza kokukhiqizwa kwamandla enuzi.
5. Izindinganiso zokusebenzisa kanye nemiyalelo yoku-oda yama-Steel Boiler Tubes
Ipayipi lensimbi elingenamthungo le-alloy le-A335P92 lihambisana nezinga eliphezulu le-ASTM A335/A335M. Uma u-oda, ulwazi olulandelayo ludinga ukucaca:
Ubuningi (isb. ezinyaweni, amamitha, noma ezimpandeni)
Igama lezinto (ipayipi elijwayelekile lensimbi engenamthungo)
Ikilasi (P92)
Indlela yokukhiqiza (ukuqeda okushisayo noma ukudweba okubandayo)
Imininingwane (isb. ububanzi bangaphandle, ukujiya kodonga, njll.)
Ubude (usayizi ohlukanisiwe kanye nosayizi oguquguqukayo)
Ukuqeda ukukhanda
Izidingo zokukhetha (isb. umfutho wamanzi kanye nokuphambuka kwesisindo okuvumelekile)
Umbiko wokuhlolwa odingekayo
Inombolo ejwayelekile
Izidingo ezikhethekile noma yiziphi izidingo ezengeziwe zokuzikhethela
Ngamafuphi, ipayipi lensimbi elingenamthungo le-A335P92 liyipayipi lensimbi elingenamthungo le-alloy elisezingeni eliphezulu lokushisa eliphezulu kanye nomfutho ophezulu, elisetshenziswa kabanzi emikhakheni eminingi ngezici zalo zokusebenza ezinhle kakhulu. Lapho u-oda futhi usebenzisa, kubalulekile ukulandela ngokuqinile amazinga nezidingo ezifanele ukuqinisekisa ukuphepha nokuthembeka kwalo.
Siyakwamukela ukuxhumana nathi ukuze uthole imininingwane eyengeziwe!
