FAQ
Q1: Puas tuaj yeem GH4169 hloov C276 hauv cov tshuaj reactor?
A: Feem ntau, NO.Tshwj tsis yog tias lub reactor tsuas yog tswj huab cua lossis chav nyob ntawm qhov kub thiab txias. Nyob rau hauv lub xub ntiag ntawm chlorides los yog muaj zog acids, GH4169 yuav corrode sai dua C276.
Q2: Cov alloy twg yog tus nqi ntau dua -zoo?
A: Qhov no nyob ntawm cov khoom siv lub neej voj voog. GH4169 feem ntau kim dua vim kev kho cua sov (Kev laus), tab sis yog tias koj xav tau lub zog ntawm 700 degree, nws tsuas yog siv tau.Tus nqi -kev daws teeb meem zoo.
Q3: Koj puas muab NDT kuaj rau cov kav dej no?
A: Yog. Tag nrho peb cov kav dej GH4169 thiab C276 tau dhau 100% Ultrasonic Testing (UT) thiab Eddy Current Testing (ET) kom paub meej.Zero Defectzoo.
