Boiler rajyog ib hom steel raj, thiab boiler raj feem ntau yog ua los ntawm seamless raj. Boiler tubes yog cov kav dej siv los thauj cov dej siab - kub thiab siab - cov kua dej siab. Lawv feem ntau yog siv rau hauv cov khoom siv xws li cov boilers, boilers, heat exchangers, thiab power stations. Boiler tubes muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, siab tiv taus, corrosion kuj, thiab lwm yam, thiab yog ib qho tseem ceeb ntawm cov khoom siv no.
Boiler raj feem ntau yog ua los ntawm carbon steel, alloy steel, stainless hlau thiab lwm yam ntaub ntawv hlau. Lawv cov kev ua tau zoo thiab kev ua haujlwm ncaj qha cuam tshuam rau kev ua haujlwm nyab xeeb thiab kev ua haujlwm ntawm lub boiler.
Cov khoom siv hluav taws xob ntawm cov raj boiler yog cov cim tseem ceeb los xyuas kom meej qhov kev ua tau zoo kawg (cov khoom siv tshuab) ntawm cov hlau. Nws nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov hlau. Nyob rau hauv cov qauv steel yeeb nkab, tensile zog (lub zog tensile, yield zog los yog yield point, elongation), hardness thiab toughness qhia tau teev raws li cov kev xav tau sib txawv, nrog rau cov khoom kub thiab kub uas yuav tsum tau los ntawm cov neeg siv.
① Feem ntau, kev khiav hauj lwm kub ntawm boiler raj yog qis dua 350 degree, thiab lawv tsuas yog ua los ntawm qis- carbon steel kub- dov tubes los yog txias - cov hlab.
② Siab- lub siab boiler raj feem ntau raug rau qhov kub thiab txias thaum siv. Nyob rau hauv qhov kev txiav txim siab ntawm - kub flue roj thiab dej vapor, cov hlab yuav oxidize thiab corrode. Cov yeeb nkab steel yuav tsum muaj lub zog ntev ntev, siab tiv thaiv oxidation thiab corrosion, thiab zoo structural stability.
Daim ntawv thov ntawm boiler tube:
① General boiler raj yog tsuas yog siv los ua cov phab ntsa dej, cov raj dej kub, cov raj dej kub, cov raj kub kub, cov raj kub kub rau cov kav dej boilers, cov pa luam yeeb loj thiab me thiab cov hlab cib, thiab lwm yam.
② High- siab boiler raj yog tsuas yog siv los tsim superheater raj, reheater raj, cua qhia raj, lub ntsiab chav boilers, thiab lwm yam. rau siab- siab thiab ultra- siab- siab boilers.

Yuav ua li cas xaiv cov khoom siv boiler raj?
1. Kub thiab siab xav tau: boilers muaj qhov sib txawv kub thiab siab yuav tsum nyob rau hauv txawv kev ua hauj lwm. Feem ntau hais lus, nyob rau hauv qhov kub thiab txias siab, feem ntau siv cov ntaub ntawv xws li ferritic stainless hlau, alloy steel thiab super alloy. Ntawm qhov kub thiab txias qis, cov pa roj carbon zoo tib yam tuaj yeem ua tau raws li qhov xav tau.
2. Corrosive ib puag ncig: Corrosive gases los yog kua tej zaum yuav muaj nyob rau hauv lub boiler ua hauj lwm ib puag ncig, yog li cov ntaub ntawv uas zoo corrosion kuj yuav tsum tau xaiv. Yog hais tias muaj acidic ib puag ncig, stainless hlau los yog npib tsib xee-raws li alloys yog ib qho kev xaiv.
3. Cov khoom siv: Boiler tube cov ntaub ntawv yuav tsum muaj cov thermal conductivity zoo thiab cov khoom siv kho tshuab kom ntseeg tau tias cov cua sov hloov mus thiab ua haujlwm zoo. Xaiv cov ntaub ntawv tsim nyog raws li kev ua haujlwm tshwj xeeb, xws li cua sov-cov hlau tsis muaj zog, siab- cov hlau tsis muaj zog thiab cov khoom siv ntxiv.
4. Kev txiav txim siab nqi: Tus nqi ntawm cov khoom sib txawv kuj yog ib qho tseem ceeb hauv kev xaiv. Ntawm qhov chaw ua tau raws li qhov yuav tsum tau siv, kev ua haujlwm ntawm cov khoom siv thiab cov nqi yuav tsum tau txiav txim siab zoo los xaiv cov khoom siv nyiaj txiag thiab tsim nyog.
