20G kev kub siab boiler raj siv tus qauvGB5310-2008Scope ntawm daim ntawv thov, yog siv rau kev tsim kev kub siab thiab siab tshaj dej raj boiler cua sov nto nrog zoo carbon steel, hlau alloy thiab stainless hlau seamless steel raj. Kev kub siab boiler seamless steel raj yog ib hom boiler raj, vim hais tias 20G siab boiler raj feem ntau siv nyob rau hauv high kub thiab siab kub tej yam kev mob, lub raj nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, oxidation thiab corrosion yuav tshwm sim. Cov yeeb nkab steel yuav tsum muaj lub zog ruaj khov, siab oxidation corrosion kuj thiab zoo microstructure stability. Kev kub siab boiler raj feem ntau yog siv los tsim kev kub siab thiab ultra-siab siab boiler superheater raj, reheater raj, yeeb nkab, lub ntsiab chav boiler, thiab lwm yam. Thaum cov yeeb nkab boiler puv dej, nws yuav tsum tau muab tso rau hauv lub sijhawm kom tsis txhob co-hydrating thiab kho cov dej theem. Tom qab lub cub tawg tau tso tseg, tom qab cov dej txias txias kom qis dua 70 degrees, cov dej hauv lub cub tawg tuaj yeem tso tawm, thiab tom qab ntawd cov tshuaj tua hluav taws xob boiler dej engase tuaj yeem siv tom qab lub net tso tawm. Kev kub siab boiler seamless steel raj feem ntau yog siv los tsim kev kub siab thiab ultra siab siab boiler superheater raj, reheater raj, yeeb nkab, lub ntsiab chav dej, thiab lwm yam. Hom boiler raj raws li qhov kub thiab txias kev ua tau zoo yog muab faib ua dav boiler raj thiab siab siab boiler raj.
