Ngomhlaka-8 kuJulayi 2023, sathumela amapayipi ensimbi angenamthungo e-ASTM A335 P92 e-Italy, futhi sawaletha ngesikhathi. Kulokhu, senza ukupakisha okuqiniswe ngo-100%, okuhlanganisa ukupakisha kwe-PVC, ukupakisha izikhwama ezilukiwe, kanye nokupakisha iphepha eligcwele isiponji, okungasetshenziswa kabusha njengelilonke. Amabhande ensimbi asetshenziselwa ukubopha amapayipi, kanti amapayipi aseduze nawo agcwele iphepha lebhamuza elilwa nokushayisana kanye nephepha lokugcwalisa isiponji, futhi ekugcineni apakishwe emabhokisini ezinkuni. Ngaphandle kwebhokisi lezinkuni, sisebenzisa nebhande lensimbi eliqinile kakhulu ukulungisa ibhokisi, ukuze sivikele ingaphakathi nangaphandle kwepayipi lonke.
Ukulethwa kwemikhiqizo evela kumakhasimende ase-Italy kubeke isisekelo esingcono semakethe yethu yaseYurophu, futhi sibheke phambili ekubambisaneni kwethu okulandelayo!
I-ASTM A335 P92 iyipayipi lensimbi elingenamthungo elihlanganisiwe, elisetshenziswa kakhulu ezitshalweni zamandla ezishisayo eminyakeni yamuva nje, ikakhulukazi kumapayipi amakhulu omusi kanye nokushisa kabusha amapayipi omusi.
Ukwakheka kwamakhemikhali e-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
Izakhiwo zemishini zepayipi lensimbi ye-ASTM A335 P92 engenamthungo: amandla okudonsa ≥ 620Map, amandla okukhiqiza ≥ 440Mpa, ukunwebeka ngemva kokuphuka ≥ 20%
Isimo Sokulethwa Kwepayipi Lensimbi Engenamthungo ye-ASEM SA335 P92: Ukulungisa + Ukushisa
Usayizi wepayipi lensimbi ye-ASEM A335 P92 engenamthungo: 60.3-765*2-120, ububanzi obuvame ukusetshenziswa 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, kanye nosayizi obunye bungenziwa ngokwezifiso ngokwezidingo zamakhasimende.
Ukusetshenziswa okuyinhloko kwepayipi lensimbi ye-alloy ye-ASME SA335 P92: esetshenziswa kakhulu ekwakhiweni kwama-superheater nama-reheater kumasethi amakhulu ejeneretha
Ipayipi le-alloy le-ASTMA335 elijwayelekile laseMelika lihambisana nezinto ze-P11, P12, P5, P9, P91 zebanga lensimbi
I-A335 P11 iyikhodi yezinto ezikhishwe yi-ASTM (American Society for Testing and Materials), kanti indinganiso kazwelonke ehambisanayo yi-15CrMo, into yensimbi ehlanganisiwe.
I-ASTM A335 P5 ifana nensimbi ye-alloy yasekhaya: 1Cr5Mo. Isakhiwo sensimbi se-1Cr5Mo siyi-martensite, enokumelana okuhle kwe-oxidation cishe kuma-degree Celsius angu-650, amandla amahle okushisa angaphansi kwama-degree Celsius angu-600, ukumuncwa okuhle kokushaqeka kanye nokuqhuba kahle kokushisa, futhi isetshenziswa kabanzi kuma-turbines anomusi.
I-American standard astm a335p91 ilingana ne-national standard 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Ukwakheka kwezinto ze-P91 (ubungako 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
Ipayipi lensimbi elingenamthungo laseMelika ipayipi lensimbi elingenamthungo i-a106 nalo liwumkhiqizo onenani elikhulu kakhulu.
Ipayipi lensimbi elingenamthungo le-ASTM A106 lingelamapayipi ensimbi ajwayelekile aseMelika, i-A106 ifaka phakathi i-A106-A, i-A106-B. Elokuqala lilingana nezinto zasekhaya ezingu-10#, kanti elokugcina lilingana nezinto zasekhaya ezingu-20#.
