Hauv cov ntsiab lus tseem ceeb ntawm cov tshuab dav hlau lossis av-raws li cov roj turbines, ntau qhov chaw ua haujlwm nyob rau hauv cov xwm txheej hnyav. Kev ntseeg ntawm cov khoom siv yog qhov kev txhawj xeeb tseem ceeb rau kev yuav cov thawj coj thiab cov kws tsim qauv tsim. Thaum cov roj kab thiab cov kab hydraulic raug kub hnyiab mus txog700℃(1292℃F)thiab siab - zaus vibrations, txheem alloys feem ntau pom cov teeb meem hauv qab no:
Kev vibration-induced nkees:Microcracks tshwm ntawm cov pob qij txha los yog ntawm cov yeeb nkab phab ntsa.
Lub cev deformation:Cov yeeb nkab "stretches" los yog sags, ua rau kev cuam tshuam los ua ke.
Siab rupture:Tsis tuaj yeem tiv taus qhov siab - cov kua dej siab thaum lub sijhawm kub siab tshaj.
PebGH4169 siab -kub npib tsib xee alloy tubingyog tsim los rau kev ncaj ncees nyob rau hauv cov hom phiaj no -tseem ceeb turbine ib puag ncig. Pom tau thoob ntiaj teb raws li kev hloov pauv rauib 718, nws teev cov kev lag luam benchmark rau industrial durability.

GH4169 (Inconel 718) Seamless Tubing rau Turbine Cav
GH4169 (Inconel 718) Seamless Tubing rau Turbine Cav
GH4169, sib npaug rau Inconel 718 (UNS NO7718) tubing, yog nag lossis daus -nickel hardening-raws li superalloy tubing siv dav hauv kev lag luam aerospace thiab lub zog tsim kev lag luam rau kev tsim seamless steel tubing rau turbine cav. Vim nws lub zog tensile siab, qaug zog, thiab creep rupture tsis kam ntawm qhov kub txog li 700℃(1300℃F), nws yog cov khoom siv rau cov khoom kub tseem ceeb -kawg.
Dab tsi yog qhov tsis zoo ntawm Inconel 718?
Qhov tsis zoo thiab lwm txoj hauv kev ntawm Inconel 718
Thaum Inconel 718 boasts zoo heev txhua yam thiab corrosion kuj zog, nws kuj muaj ib co drawbacks: High nqi: Vim nws complex manufacturing txheej txheem, Inconel 718 yog kim. Yooj yim rau txheej txheem: Nws cov hardness siab ua rau cov khoom tshem tawm nyuaj thiab ua kom cov cuab yeej hnav.
