Ngomhla wesi-8 kweyeKhala ngo-2023, sathumela imibhobho yentsimbi ye-ASTM A335 P92 e-Itali, saza sayihambisa ngexesha. Ngeli xesha, senze ukupakisha okuqinisiweyo nge-100%, kuquka ukupakisha kwe-PVC, ukupakisha iingxowa ezilukiweyo, kunye nokupakisha iphepha elizaliswe yisponji, elinokusetyenziswa kwakhona njengesiqhelo. Imitya yentsimbi isetyenziselwa ukubopha imibhobho, kwaye iityhubhu ezisecaleni kwazo zizaliswe ngephepha leqamza elichasene nokungqubana kunye nephepha lokugcwalisa isiponji, kwaye ekugqibeleni zipakishwe kwiibhokisi zomthi. Ngaphandle kwebhokisi yomthi, sisebenzisa nebhanti yentsimbi enamandla kakhulu ukulungisa ibhokisi, ukuze sikhusele ngaphakathi nangaphandle kombhobho iyonke.
Ukuhanjiswa kweemveliso ezivela kubathengi base-Itali kubeke isiseko esingcono kwimarike yethu yaseYurophu, kwaye sijonge phambili kwintsebenziswano yethu elandelayo!
I-ASTM A335 P92 ngumbhobho wentsimbi engenamthungo oxutyiweyo, osetyenziswa kakhulu kwizityalo zamandla obushushu kwiminyaka yakutshanje, ikakhulu kwiipayipi eziphambili zomphunga kunye nokufudumeza kwakhona iipayipi zomphunga.
Ulwakhiwo lweekhemikhali ze-A335 P92: C: 0.07~0.13 Si: ≤0.50 Mn: 0.30~0.60 P≤0.020 S≤0.010 Cr: 8.50~9.50 Mo: 0.30~0.60Ni≤0.40 V:0.15~0.25 N:0.03~0.07 Al: ≤0.02 Ti: ≤0.01 Zr≤0.01Nb: 0.04~0.09 W: 1.5~2.0 B: 0.001~0.006
Iimpawu zoomatshini zombhobho wentsimbi ye-ASTM A335 P92 engenamthungo: amandla okutsalwa ≥ 620Map, amandla okukhupha ≥ 440Mpa, ukunwebeka emva kokuqhekeka ≥ 20%
I-ASEM SA335 P92 I-Seamless Alloy Steel Pipe Delivery Status: Ukulungisa + Ukushisa
Ubungakanani bombhobho wentsimbi ye-ASEM A335 P92 engenamthungo: 60.3-765*2-120, ububanzi obusetyenziswa rhoqo yi-60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711, 762, kunye nobukhulu obunye bunokwenziwa ngokwezifiso ngokweemfuno zabathengi.
Ukusetyenziswa okuphambili kombhobho wentsimbi ye-ASME SA335 P92 alloy: isetyenziswa kakhulu ekwenzeni ii-superheaters kunye nee-reheaters kwiiseti ezinkulu zejenereyitha
Umbhobho we-alloy we-ASTMA335 osemgangathweni waseMelika uhambelana nezinto zentsimbi ze-P11, P12, P5, P9, P91
I-A335 P11 yikhowudi yezinto ezikhutshwe yi-ASTM (i-American Society for Testing and Materials), kwaye umgangatho wesizwe ohambelanayo yi-15CrMo, izinto zentsimbi ye-alloy.
I-ASTM A335 P5 ihambelana nentsimbi ye-alloy yasekhaya: 1Cr5Mo. Ulwakhiwo lwesinyithi lwe-1Cr5Mo yi-martensite, enokumelana okuhle kwe-oxidation malunga nama-650 degrees Celsius, amandla amahle obushushu angaphantsi kwama-600 degrees Celsius, ukufunxwa kakuhle kwe-shock kunye nokuqhuba kakuhle kobushushu, kwaye isetyenziswa kakhulu kwiiturbines zomphunga.
I-astm a335p91 esemgangathweni yaseMelika ilingana ne-standard kazwelonke ye-10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Ukwakheka kwezinto ze-P91 (ubunzima besithako%):
C 0.08~0.12; Mn 0.30~0.60; Si 0.20~0.50; P ≤0.02; S ≤0.01; Cr 8.0~9.5;
Mo 0.85~1.05; I-V 0,18~0,25; Nb 0.06~0.1; N 0.03~0.07; Al ≤0.04; Ni ≤0.4
Umbhobho wesinyithi osemgangathweni waseMelika ongenamthungo i-a106 umbhobho wesinyithi ongenamthungo nawo ngumveliso onomlinganiselo omkhulu kakhulu.
Umbhobho wentsimbi engenamthungo we-ASTM A106 ngowepayipi yentsimbi esemgangathweni yaseMelika, i-A106 ibandakanya i-A106-A, i-A106-B. Owokuqala ulingana nezinto zasekhaya ze-10#, kwaye owokugqibela ulingana nezinto zasekhaya ze-20#.
