Pombi yesimbi isina musono yeA335P92 alloy, specification 48.3*7.14 (kureva dhayamita yekunze 48.3mm, ukobvu hwemadziro 7.14mm), sepombi yebhoyira ine pressure yakakwira, chiyero chekushandisa kwayo iASTM A335M. Inotevera ongororo yakadzama yepombi yesimbi:
I. Pfupiso huru yeSimbi Boiler Tubes
Pombi yesimbi isina musono yeA335P92 alloy imhando yepombi yesimbi isina musono yemhando yepamusoro inodziya uye ine kumanikidzwa kwakanyanya, iyo inoshandiswa zvakanyanya munzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya senge pombi huru yemhepo uye pombi yemhepo inodziya zvakare yezvivakwa zvemagetsi zvinopisa. Chinhu chayo iP92, iri yesimbi yeUnited States nhamba ASTM A335 P92 martensitic inodzivirira kupisa.
Chechipiri, kuumbwa kwemakemikari eSimbi Boiler Tubes
Musanganiswa wemakemikari weA335P92 alloy steel pipe unodzorwa nemazvo, kunyanya kusanganisira kabhoni, manganese, phosphorus, sarufa, silicon, chromium, molybdenum, vanadium, nitrogen, nickel, aluminium, niobium, tungsten uye boron nezvimwe zvinhu. Rudzi rwezvinhu rwacho nderwekuti:
Kabhoni (C): 0.07~0.13%
Manganese (Mn): 0.30-0.60%
Phosphorus (P): ≤0.020%
Sarufa (S): ≤0.010%
Silikoni (Si): ≤0.50%
Chromium (Cr): 8.5~9.50%
Molybdenum (Mo): 0.30~0.60% (asi zvakakosha kuziva kuti kana ichienzaniswa nesimbi yeSA-335P91, simbi yeSA-335P92 inoderedza zviri mukati meMo element nemazvo, uye inovandudza mashandiro echinhu ichi nekuwedzera huwandu hwakati hweW)
Vanadium (V): 0.15~0.25%
Nitrogen (N): 0.03~0.07%
Nickel (Ni): ≤0.40%
Aruminiyamu (Al): ≤0.04%
Niobium (Nb): ≤0.040~0.09%
Tungsten (W): 1.5~2.0%
Boron (B): 0.001~0.006%
Chikamu chakaringana chezvinhu izvi chinoita kuti pombi yesimbi isina musono yeA335P92 alloy ive nekudzivirira ngura zvakanyanya pakupisa kwakanyanya, kudzivirira oxidation, simba rekupisa kwakanyanya uye hunhu hwekukambaira.
3. Hunhu hweSimbi dzeBoiler Tubes
Pombi yesimbi isina musono yeA335P92 ine hunhu hwakanaka hwemakanika, hunoratidzwa seinotevera:
Simba rekudhonza: ≥620MPa
Simba rekuwedzera: ≥440MP
Hunhu uhwu hwemakanika hunovimbisa kuchengetedzeka uye kuvimbika kwemachubhu esimbi munzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya.
4. Munda wekushandisa weSimbi Boiler Tubes
Pombi yesimbi isina musono yeA335P92 alloy nekuda kwehunhu hwayo hwakanaka hwekushanda, inoshandiswa zvakanyanya muminda inotevera:
Chiteshi chemagetsi chinodziya: sechinhu chakakosha chepombi huru yemhepo inodziya uye pombi yemhepo inodziyazve, inogona kutsungirira kupisa kwakanyanya uye mamiriro ekumanikidzwa kwakanyanya kuti ive nechokwadi chekuti chiteshi chemagetsi chinoshanda zvakachengeteka.
Petrokemikari: Mukugadzirisa peturu nekugadzira makemikari, inoshandiswa kugadzira michina yakaita sema reactor, heat exchangers nemapaipi ekutumira zvinhu kuti ikwane zvinodiwa nekupisa kwakanyanya, kumanikidzwa uye ngura.
Indasitiri yesimba renyukireya: Mumafekitori esimba renyukireya, inoshandiswa kugadzira masisitimu ekutonhodza ereactor yenyukireya nemapaipi akafanana kuitira kuve nechokwadi chekuchengetedzeka nekugadzikana kwekugadzirwa kwesimba renyukireya.
5. Maitiro ekushandisa uye mirairo yekuodha machubhu esimbi
Pombi yesimbi isina musono yeA335P92 alloy inoenderana neASTM A335/A335M executive standard. Pakuodha, ruzivo runotevera runofanira kujeka:
Huwandu (semuenzaniso mutsoka, mamita, kana midzi)
Zita rezvinhu (pombi yesimbi isina musono yesimbi)
Kirasi (P92)
Nzira yekugadzira (kupedzisa kupisa kana kudhirowa kunotonhora)
Magadzirirwo (semuenzaniso dhayamita yekunze, ukobvu hwemadziro, nezvimwewo)
Kureba (hukuru hwakakamurwa uye hukuru hunoshanduka)
Kupedzisa kugadzira
Zvinodiwa pakusarudza (semuenzaniso kumanikidzwa kwemvura uye kutsauswa kwehuremu kunobvumidzwa)
Mushumo webvunzo unodiwa
Nhamba yakajairika
Zvinodiwa zvakakosha kana chero zvimwe zvinodiwa zvekuwedzera
Muchidimbu, pombi yesimbi isina musono yeA335P92 alloy ipombi yesimbi isina musono yemhando yepamusoro inodziya zvakanyanya uye ine pressure yakakwira, iyo inoshandiswa zvakanyanya muminda yakawanda ine hunhu hwayo hwakanaka hwekushanda. Pakuodha nekushandisa, zvinodikanwa kunyatsotevedzera zvinodiwa uye zvinodiwa kuti ive nechokwadi chekuti yakachengeteka uye yakavimbika.
Tinokugamuchirai kuti mutibate kuti muwane rumwe ruzivo!
