Nrog tus qauv tshwj xeeb, ua kom zoo tshaj plaws rau cov choj lub zog, thiab kev kho mob ntawm kev lag luam, thiab kev kho kom zoo ntawm kev ua haujlwm, thiab cov ntug dej hiav txwv, thiab cov khoom lag luam
Core Engineering Khoom
Alloy Muaj pes tsawg: Muaj CU ({0.25-0.45%), cr (0.30-0.65%), thiab sau ntom ntom ntom-Qhovoxide txheej uas txo cov nqi corrosion los ntawm2-8 lub sij hawmPiv rau cov pa roj carbon hlau . phosphorus (}}}}}}}} 12%) ua kom muaj zog weldability thiab ductility.
Neeg kho tshuab kev ua tau zoo:
Paib lub zog ntau dua los yog sib npaug rau 295 MPA tsawg dua lossis sib luag dua lossis sib npaug ntawm 24 hli, ua kom muaj kev ncaj ncees ntau dua los yog sib luag rau 24 hli
Cuam tshuam tsis: ntau dua lossis sib npaug ntawm 34j ntawm -20}} {, tseem ceeb rau cov kev siv seismic thiab tsawg-{5}}
Huab cua & Corrosion tsis kam
Kev Txau Txau Ua Haujlwm: HlaASTM B117Kuaj nrog tsawg dua lossis sib npaug ntawm 0 {. 1000 teev hauv 5% NacL daws, tseem ceeb rau ntug hiav txwv thiab cov tub rog.
UV & Acid Refrantance: Tsis kam UV laus ibIso 4892-3Thiab sulfuric ib puag ncig (70℃50% horso₄) nrog cov nqi corrosion tsawg dua lossis sib npaug rau hauv nroog thiab thaj chaw muaj kev lag luam {3}
Qaug zog: Optimized rau Cyclic Chaw thau khoom nrog qaug zog muaj zog txogRog 80- fil90(Eurocode 3), ua kom muaj kev sib tw hauv cov ntawv thov kev sib tw siab xws li kev xa cov yees thev naus laus zis {2}
