Txheej txheem cej luam
Peb txoj kev loj hlob nyob ntawm cov cuab yeej siv siab heev, cov txuj ci zoo heev thiab txuas ntxiv dag zog rau kev siv tshuab rau peb cov khoom lag luam zoo steel yeeb nkab, Peb tab tom yuav txuas ntxiv mus ua kom peb lub tuam txhab thiab muab cov khoom zoo tshaj plaws nrog cov nqi sib tw. Txhua qhov kev nug lossis lus pom zoo txaus siab heev. Nco ntsoov tuav peb dawb. Peb lub tuam txhab ua haujlwm los ntawm txoj cai kev ua haujlwm ntawm "kev ncaj ncees-raws li, kev koom tes tsim, tib neeg taw qhia, yeej-yeej kev koom tes". Peb cia siab tias peb tuaj yeem muaj kev sib raug zoo nrog cov neeg ua lag luam los ntawm thoob plaws lub ntiaj teb
P91 tsis tsuas yog muaj oxidation tsis kam thiab kub kub chav corrosion kuj, tab sis kuj muaj kev cuam tshuam zoo toughness thiab siab thiab ruaj khov ntev yas thiab thermal zog. Thaum qhov kev pabcuam kub qis dua 620 ℃, nws qhov kev cia siab yog siab dua li ntawm austenitic stainless hlau. Tshaj li 550 ℃, qhov kev pom zoo tsim kom muaj kev ntxhov siab yog li ob zaug ntawm T9 thiab 2.25Cr-1Mo steel. Nws tuaj yeem siv los ua cov kub kub superheater thiab reheater steel yeeb nkab rau subcritical thiab supercritical boiler phab ntsa kub ≤ 625 ℃, siab kub header thiab chav yeeb nkab phab ntsa kub ≤600 ℃, nrog rau nuclear fais fab kub exchanger thiab rauv tube ntawm roj av cracking unit.
Daim ntawv thov
Nws yog tsuas yog siv los ua cov khoom siv zoo hlau steel boiler yeeb nkab, cov yeeb nkab sib hloov cua sov, siab siab chav yeeb nkab rau roj av thiab tshuaj lom neeg kev lag luam.
Qib tseem ceeb
Qib ntawm cov yeeb nkab zoo zoo: P1, P2, P5, P9, P11, P22, P91, P92 thiab lwm yam
