Machubu a Boiler a Chitsulo a ASTM A192, ASTM A179, ASTM A209, ASTM A210

Chitoliro chachitsulo chopanda msoko cha A335P92, specifications 48.3*7.14 (monga m'mimba mwake wakunja 48.3mm, makulidwe a khoma 7.14mm), ngati chitoliro cha boiler champhamvu kwambiri, muyezo wake wogwiritsira ntchito ndi ASTM A335M. Izi ndi kusanthula mwatsatanetsatane kwa chitoliro chachitsulo:

I. Chidule cha Machubu a Boiler a Chitsulo
Chitoliro chachitsulo chosasunthika cha A335P92 ndi mtundu wa chitoliro chachitsulo chosasunthika chapamwamba kwambiri komanso chosasunthika cha aloyi, chomwe chimagwiritsidwa ntchito kwambiri m'malo otentha kwambiri komanso opanikizika kwambiri monga payipi yayikulu ya nthunzi ndi payipi yotenthetseranso nthunzi ya zomera zamagetsi. Zinthu zake ndi P92, zomwe ndi za chitsulo cha United States cholimba ndi ASTM A335 P92 martensitic.

Chachiwiri, kapangidwe ka mankhwala a machubu a boiler achitsulo
Kapangidwe ka mankhwala a chitoliro chachitsulo chosasunthika cha A335P92 kamayang'aniridwa bwino, makamaka kuphatikiza kaboni, manganese, phosphorous, sulfure, silicon, chromium, molybdenum, vanadium, nayitrogeni, nickel, aluminiyamu, niobium, tungsten ndi boron ndi zinthu zina. Mndandanda wazinthu zomwe zili mkati mwake ndi motere:

Kaboni (C): 0.07~0.13%
Manganese (Mn): 0.30-0.60%
Phosphorus (P): ≤0.020%
Sulfure (S): ≤0.010%
Silikoni (Si): ≤0.50%
Chromium (Cr): 8.5~9.50%
Molybdenum (Mo): 0.30~0.60% (koma ndikofunikira kudziwa kuti poyerekeza ndi chitsulo cha SA-335P91, chitsulo cha SA-335P92 chimachepetsa moyenera kuchuluka kwa chinthu cha Mo, ndipo chimawongolera magwiridwe antchito a chinthucho powonjezera kuchuluka kwa W)
Vanadium (V): 0.15~0.25%
Nayitrogeni (N): 0.03~0.07%
Nikeli (Ni): ≤0.40%
Aluminiyamu (Al): ≤0.04%
Niobium (Nb): ≤0.040~0.09%
Tungsten (W): 1.5~2.0%
Boroni (B): 0.001~0.006%

Kuchuluka koyenera kwa zinthuzi kumapangitsa kuti chitoliro chachitsulo chopanda msoko cha A335P92 chikhale ndi mphamvu zabwino kwambiri zotsutsana ndi dzimbiri kutentha kwambiri, kukana okosijeni, mphamvu yotentha kwambiri komanso mphamvu zokwawa.

3. Kapangidwe ka makina a machubu a boiler achitsulo
Chitoliro chachitsulo chopanda msoko cha A335P92 chili ndi makhalidwe abwino kwambiri a makina, omwe akuwonetsedwa motere:

Mphamvu yokoka: ≥620MPa
Mphamvu yotulutsa: ≥440MP
Kapangidwe ka makina kameneka kamatsimikizira chitetezo ndi kudalirika kwa machubu achitsulo m'malo otentha kwambiri komanso opanikizika kwambiri.

4. Malo ogwiritsira ntchito machubu a boiler achitsulo
Chitoliro chachitsulo chopanda msoko cha A335P92 chifukwa cha magwiridwe ake abwino kwambiri, chimagwiritsidwa ntchito kwambiri m'magawo otsatirawa:

Chopangira magetsi chotenthetsera: monga chinthu chofunikira kwambiri pa payipi yayikulu ya nthunzi ndi payipi yotenthetseranso nthunzi, imatha kupirira kutentha kwambiri komanso malo opanikizika kwambiri kuti iwonetsetse kuti fakitole yamagetsi ikugwira ntchito bwino.

Petrochemical: Poyeretsa mafuta ndi kupanga mankhwala, imagwiritsidwa ntchito popanga zipangizo monga ma reactor, zosinthira kutentha ndi mapaipi otumizira kuti akwaniritse zofunikira za kutentha kwambiri, kupanikizika ndi dzimbiri.

Makampani opanga mphamvu za nyukiliya: M'mafakitale opanga mphamvu za nyukiliya, amagwiritsidwa ntchito popanga makina oziziritsira a reactor ya nyukiliya ndi mapaipi ena ofanana nawo kuti atsimikizire chitetezo ndi kukhazikika kwa kupanga mphamvu za nyukiliya.

5. Miyezo yogwiritsira ntchito ndi malangizo oyitanitsa machubu a Boiler a Chitsulo
Chitoliro chachitsulo chopanda msoko cha A335P92 chikugwirizana ndi muyezo wa ASTM A335/A335M. Mukayitanitsa, mfundo zotsatirazi ziyenera kumveka bwino:

Kuchuluka (monga mapazi, mita, kapena mizu)

Dzina la zinthu (chitoliro chopanda msoko chachitsulo chopanda msoko)
Kalasi (P92)

Njira yopangira (kumaliza kotentha kapena kujambula kozizira)
Mafotokozedwe (monga m'mimba mwake wakunja, makulidwe a khoma, ndi zina zotero)
Utali (kukula kogawanika ndi kukula kosiyanasiyana)
Mapeto opangira
Zofunikira posankha (monga kuthamanga kwa madzi ndi kusinthasintha kovomerezeka kwa kulemera)
Lipoti loyesera lofunikira
Nambala yokhazikika
Zofunikira zapadera kapena zofunikira zina zowonjezera

Mwachidule, chitoliro chachitsulo chopanda msoko cha A335P92 ndi chitoliro chachitsulo chopanda msoko chapamwamba kwambiri komanso chotentha kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha magwiridwe ake abwino kwambiri. Mukamayitanitsa ndikugwiritsa ntchito, ndikofunikira kutsatira miyezo ndi zofunikira kuti zitsimikizire kuti ndi zotetezeka komanso zodalirika.

Takulandirani kuti mulankhule nafe kuti mudziwe zambiri!
