1.} cov khoom siv
ASTM A178 GRC yog cov khoom siv rau hluav taws xob tiv thaiv welded cov pa roj carbon monoxe {} nws muaj cov pa roj carbon monoxe (c)}} {{5 5}}%, phosphorus (p) ntawm qhov siab tshaj plaws ntawm 0 {} 035%, thiab sulfur (s) ntawm qhov siab tshaj plaws ntawm 0.035%.
2.}} kev xav tau
Tshuaj lom neeg muaj pes tsawg leeg
Los ntawm cov khoom siv, nws tuaj yeem pom tias muaj cov ntsiab lus meej thiab cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide. cov yeeb nkab, thiab nruj me ntsis ntawm phosphorus thiab cov kab sau cov lus hais tuaj yeem txo cov yeeb nkab thiab thermal tawg ua ntawm cov yeeb nkab .
3. Ntau Lawm Txheej Txheem Yuav Tsum Tau
Raws li qhov tsis kam welded yeeb nkab, cov txheej txheem specifications ntawm kev tswj hwm vuam, yog li ntawd cov kev xav tau ntawm cov kev xav tau ntawm cov kev xav tau ntawm cov kev xav tau ntawm cov kev xav tau ntawm cov kev xav tau ntawm cov dej num supercheats hauv qhov kub thiab kub siab chaw ib puag ncig. tib lub sijhawm, nws yuav tsim nyog ua kom tau cov yeeb nkab kom txhim kho nws cov qauv thiab kev ua haujlwm {}}
4.} kev xav tau
Cov kev yuav tsum muaj: nws yuav tsum muaj lub siab muaj zog los tiv thaiv cov dej kub thiab kev kub siab rau kev ua tsis tiav xws li tawg yeeb .
Thaum tshav kub kub kuj yuav tsum tau: Nws tuaj yeem siv rau ib puag ncig ntev nyob rau hauv qhov kev tiv thaiv kub, kom ntseeg tau lub neej kev nyab xeeb thiab kev nyab xeeb ntawm cov yeeb nkab .
5.} daim ntawv thov
Boiler teb
Hauv lub boiler, Astm Welded yeeb nkab tuaj yeem siv ua cov raj cua kub thiab kub thiab txias thiab kub thiab txias thiab kub thiab txias thiab kub thiab txias thiab kub thiab txias thiab kub thiab txias thiab kub thiab txias thiab txias hloov .
Soj Ntsuam Superer
Kev ua haujlwm ntawm SuperHeater yog kom ua kom sov cov pa hluav taws xob thiab ua haujlwm ntawm cov khoom siv hluav taws xob thiab cov txheej txheem hluav taws xob ntau dua los yog cov txheej txheem hluav taws xob.
