Chitoliro chachitsulo chopanda msoko cha ASTM A335 P91: Kugwiritsa Ntchito, Kutenthetsa ndi Malangizo Ogulira

Pa makina opangira magetsi otentha kwambiri komanso amphamvu kwambiri, kusankha zinthu sikungokhudza kusankha chitoliro chachitsulo champhamvu kwambiri.Chitoliro chachitsulo chosasunthika cha ASTM A335 P91imatchulidwa kwambiri kuti igwiritsidwe ntchito kutentha kwambiri chifukwa kapangidwe kake ka aloyi ndi momwe imagwiritsidwira ntchito kutentha zimagwirizana kwambiri ndi magwiridwe antchito a makina kwa nthawi yayitali.

Komabe, kwa ogula, vuto lenileni nthawi zambiri ndi kusapeza wogulitsa mapaipi a P91. Ndi kuonetsetsa kutigiredi, chithandizo cha kutentha, kuyang'anira, zolemba ndi kutsatazonse zikugwirizana ndi zomwe zafotokozedwa mu polojekitiyi.

Chifukwa ChiyaniASTM A335 P91 Kodi Amagwiritsidwa Ntchito Mu Makina Amagetsi Otentha Kwambiri?

ASTM A335 P91ndi chitoliro chopanda msoko cha ferritic alloy-steel chomwe chimapangidwa kuti chigwiritsidwe ntchito kutentha kwambiri. ASTM imazindikira A335 ngati chitoliro chophimba chitoliro chopanda msoko cha ferritic alloy-steel chomwe chimagwiritsidwa ntchito kutentha kwambiri, chokhala ndi zofunikira zokhudzana ndi kapangidwe ka mankhwala, mawonekedwe a makina, kuuma ndi mayeso.

P91 ili ndi pafupifupi 8–9.5% ya chromium ndi 0.85–1.05% ya molybdenum, pamodzi ndi zowonjezera zolamulidwa kuphatikizapo vanadium, niobium ndi nayitrogeni. Kapangidwe ka aloyi kameneka kamathandizira mphamvu ndi kukana kugwedezeka komwe kumafunika pa ntchito yovuta.

Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiriChitoliro chachitsulo cha P91 alloykuphatikizapo:

· Nthunzi yaikulu ya siteshoni yamagetsi ndi makina otenthetsera otentha
· Mapaipi a boiler ndi superheater
· Mapaipi a nthunzi yotentha kwambiri
· Malo opangira magetsi okhala ndi mafuta osungiramo zinthu zakale komanso magetsi ozungulira molumikizana
· Mapaipi otenthetsera kwambiri ndi zida zina zokhudzana nawo

Giredi yoyenera iyenera kusankhidwa nthawi zonse malinga ndi kutentha kwa kapangidwe kake, kuthamanga kwa mpweya, momwe ntchito ikuyendera komanso khodi yogwiritsira ntchito ya uinjiniya m'malo mongosankha dzina la giredi yokha.

P91 vs P22: N’chifukwa Chiyani Ogula Sangawaone Ngati Olowa M’malo Osavuta?

P91 vs P22ndi funso lofala kwambiri pankhani yogula magetsi.

P22 ndi chitsulo cha Cr-Mo chopanda aloyi wochepa, pomwe P91 ili ndi chromium yambiri komanso kapangidwe ka aloyi kovuta. Chifukwa chake, mitundu iwiriyi ili ndi mawonekedwe osiyanasiyana azinthu ndi ntchito zomwe zimagwiritsidwa ntchito.

Pa kugula, mfundo yaikulu ndi iyi:

P91 siyenera kusinthidwa ndi P22—kapena P22 ndi P91—chifukwa chakuti miyeso yake ndi yofanana.

Kuyerekeza koyenera kuyenera kuphatikizapo:

· Kutentha ndi kupanikizika kwa kapangidwe
· Zofunikira pa mphamvu ya nthawi yayitali komanso yolimba
· Kapangidwe ka mankhwala
· Kuchiza kutentha
· Kapangidwe ka makina
· Zofunikira pa njira yowotcherera
Zofunikira pa PWHT
· Zofunikira za NDE ndi zowunikira
· Ma code ogwiritsira ntchito kapangidwe ndi zomangamanga

Izi ndizofunikira kwambiri pogula zinthu zina zosinthira makina opangira magetsi omwe alipo kale.

P91 vs T91: Kodi Ubale Ndi Chiyani?

Kusaka kwina komwe kumachitika kawirikawiri ndiP91 vs T91.

Magulu awiriwa ndi ofanana kwambiri mu chemistry ya alloy, koma ndi a ASTM yosiyana.

ASTM A335 P91yatchulidwa kuti igwiritsidwe ntchito pa chitoliro cha ferritic alloy-steel chopanda msoko, pomweASTM A213 T91Ili ndi mawonekedwe a boiler ya ferritic ndi austenitic alloy-steel boiler, superheater ndi machubu osinthira kutentha.

Chifukwa chake, P91 ndi T91 siziyenera kuonedwa ngati zinthu zosinthika chifukwa chakuti mawonekedwe awo a mankhwala ndi ofanana.

Fomu ya chinthucho, kukula kwake, zofunikira pakupanga, momwe chikugwiritsidwira ntchito, ndi tsatanetsatane wa polojekitiyo ziyenera kufufuzidwa musanasinthe.

Chifukwa Chake Kuchiza Kutentha Ndikofunikira Kwambiri pa P91

KwaChitoliro chachitsulo chopanda msoko cha P91, chithandizo cha kutentha si chinthu chachiwiri chomwe chimachitika chifukwa cha kupanga. Ndi gawo lofunika kwambiri pakupeza zinthu zofunika.

Chifukwa chake, mfundo yogulira ya P91 iyenera kufotokoza momveka bwino zomwe zikufunika:

· Kuchiza kutentha
· Zolemba za kutentha
· Zotsatira za mayeso a makina
· Zotsatira za kuuma
· Kapangidwe ka mankhwala
· Kuzindikira kutentha/malo
· Kope loyenera lovomerezeka

ASTM A335 imafuna kuti zinthuzo zigwirizane ndi zofunikira za mankhwala, zomangira ndi zolimba, ndipo muyezowo umaphatikizaponso zofunikira pakuwunika kwa hydrostatic ndi zosawononga.

Pachifukwa ichi, ogula ayenera kupewa kugula P91 kuchokera pa mtengo wokhawo womwe umati “ASTM A335 P91.” Mafotokozedwe athunthu aukadaulo ndi ofunikira.

NDE ndi Kuyang'anira: Kodi Ogula Ayenera Kuyang'ana Chiyani?
