I-ASTM A213 T92 (ASME SA213 T92)iyipayipi lensimbi elingenamthungo eline-chromium alloy ephezulu, eliqukethe u-8.5–9.5% Cr, u-0.2–0.5% W kanye no-Mo, u-V, u-Nb, nezinye izinto zokuhlanganisa.Ngemva kokwenza kube ngokwejwayelekile nokulungisa, leli payipi lensimbi linamandla okushisa aphezulu kakhulu, ukumelana okuhle kakhulu kokukhukhuleka, kanye nokuqina okuhle kokushisa.
Amapayipi ensimbi e-T92 avame ukusetshenziswa ezingxenyeni ezibalulekile zama-boiler anomfutho ophezulu kanye nomfutho ophezulu kakhulu, ama-heat exchanger, kanye nama-superheater, futhi asetshenziswa kabanzi embonini yamandla, i-petrochemical, kanye ne-energy.
Inombolo ye-UNS yi-K92460.
Insimbi yeBotopungumthengisi wepayipi lensimbi ye-alloy ochwepheshe futhi othembekile eShayina, okwazi ukuhlinzeka ngokushesha amaphrojekthi akho ngama-grade ahlukahlukene amapayipi ensimbi ye-alloy, okuhlanganisaI-T5 (K41545), I-T9 (K90941),I-T11 (K11597),I-T12 (K11562),I-T22 (K21590), futhiI-T91 (K90901).
Imikhiqizo yethu isezingeni elithembekile, inentengo encintisanayo, futhi isekela ukuhlolwa komuntu wesithathu.
Izidingo zokwakheka kwamakhemikhali ze-T92 ziqinile kakhulu. Ukulawulwa okunembile kwezinto ezibalulekile njenge-C, Cr, Mo, W, V, Nb, B, kanye ne-N kuqinisekisa ukusebenza kahle kwamapayipi ensimbi. Ukuhlolwa kokwakheka kwamakhemikhali kufanele kwenziwe ngokuhambisana nezidingo ezifanele ze-ASTM A1016.
