High-pressure boiler seamless steel yeeb nkab yog ib hom boiler yeeb nkab, uas muaj cov kev cai nruj ntawm cov hlau hom thiab cov txheej txheem siv los tsim cov yeeb nkab steel. High-pressure boiler kav feem ntau nyob rau hauv qhov kub thiab txias thaum lub sij hawm siv. Nyob rau hauv qhov kev txiav txim ntawm high-temperature flue gas thiab dej vapor, cov kav dej yuav oxidize thiab corrode. Cov yeeb nkab steel yuav tsum muaj lub zog ruaj khov, muaj zog tiv thaiv oxidation thiab corrosion, thiab kev ruaj ntseg zoo. High-pressure boiler kav yog tsuas yog siv los tsim superheater kav, reheater kav, gas guide kav, main steam pipes, thiab lwm yam.
Cov teeb meem tshwm sim hauv kev kho saum npoo thiab cov khoom lag luam ntawm cov high-pressure boiler seamless steel kav:
[1] Qhov saum npoo ntawm high-pressure boiler seamless steel kav yog inconsistent: tsuas pickling thiab passivation ntawm welds kuj ua rau uneven nto, cuam tshuam rau cov tsos.
[2] Nws yog ib qho nyuaj rau tshem tawm khawb ntawm high-pressure boiler seamless steel kav: pickling thiab passivation ntawm tag nrho cov yeeb nkab tsis tuaj yeem tshem tawm ntau yam khawb thaum lub sij hawm ua, thiab nws tsis tuaj yeem tshem tawm impurities xws li carbon hlau thiab spatter uas adheres rau stainless. steel nto vim khawb thiab vuam spatter, ua rau cov tshuaj corrosion los yog electrochemical corrosion thiab xeb nyob rau hauv lub xub ntiag ntawm corrosive media.
