Boiler raj yog seamless raj thiab yog ua los ntawm cov hlau los yog hlau alloy.Lawv tau dav siv nyob rau hauv chav boilers, rau lub hwj chim tiam, nyob rau hauv fossil fuel nroj tsuag, industrial processing nroj tsuag, hluav taws xob fais fab nroj tsuag, thiab lwm yam. Boiler hlab yuav yog nruab nrab-siab boiler yeeb nkab los yog high-pressure boiler yeeb nkab.
Boiler raj feem ntau tsim nyob rau hauv cov txheej txheem seamless.Nov yog cov ncauj lus kom ntxaws txog yuav ua li cas lawv tau ua:
Boiler Tubes Ua li cas?
Ob qho tib si nruab nrab-siab thiab siab-siab boiler raj tau ua tib yam txheej txheem ntawm kev tsim khoom, uas suav nrog kev kos duab zoo, ci ntsa iab, kub dov, txias kos thiab nthuav dav tshav kub.Txawm li cas los xij, cov kauj ruam hauv qab no tau ua los ua kom cov kav dej muaj zog muaj zog thiab tiv taus ntau dua.
Kev kho cua sov muaj xws li cua sov thiab cua txias ntawm cov kav dej kub siab boiler uas ua rau kom muaj zog, hardness thiab hnav tsis kam.Cov kauj ruam sib txawv uas tuaj nyob rau hauv kev kho cua sov muaj xws li quenching, tempering thiab annealing.
quenching yog ua kom lub hardness ntawm high-pressure boiler raj.Cov yeeb nkab yog rhuab sib npaug mus rau qhov tsim nyog kub thiab ces sai sai rau hauv dej los yog roj kom txias sai.Qhov no yog ua raws li cua txias hauv huab cua lossis hauv thaj chaw khov.
Tempering yog siv los tshem tawm brittleness ntawm cov yeeb nkab.quenching tuaj yeem ua rau cov yeeb nkab ua tapping lossis tawg.
Annealing tuaj yeem tshem tawm cov kev ntxhov siab sab hauv hauv cov yeeb nkab.Nyob rau hauv cov txheej txheem no, lub seamless raj yog rhuab mus rau qhov tseem ceeb kub thiab ces sab laug rau qeeb txias nyob rau hauv tshauv los yog txiv qaub.
Kev tshem tawm xeb ntawm Boiler Tube
Muaj ntau ntau txoj hauv kev los tshem tawm xeb los ntawm lub boiler raj, qhov yooj yim tshaj yog tu siv cov kuab tshuaj thiab emulsion.Txawm li cas los xij, qhov no tuaj yeem tshem tawm tsuas yog plua plav, roj, thiab lwm yam, tab sis yuav tsis tshem cov yeeb nkab kom tshem tawm cov organic seem.
Txoj kev thib ob yog kev tshem tawm xeb siv phau ntawv lossis cov cuab yeej hluav taws xob.Cov cuab yeej tu tuaj yeem tshem tawm cov oxide txheej, vuam slag thiab xeb.
Txoj kev siv ntau tshaj plaws yog los ntawm kev siv tshuaj thiab electrolytic, tseem hu ua acid tu.
Kev tshem tawm xeb yog txoj hauv kev zoo tshaj plaws rau kev ntxuav cov raj boiler vim nws tuaj yeem tshem tawm cov av, oxide thiab xeb mus rau qib siab dua.Tsis tas li ntawd, nws tuaj yeem ua kom cov roughness ntawm cov yeeb nkab.
Thaum xaiv cov raj boiler, nrhiav cov hauv qab no los xaiv cov raj zoo thiab zoo:
1. Saib ntawm ntu ntu ntawm lub raj.Ib tug zoo zoo seamless raj yuav muaj ib tug smooth-section thiab yuav tsis muaj pob thiab irregularities.
2. Tshawb xyuas qhov ntom ntawm cov yeeb nkab kom nkag siab txog feem pua ntawm impurities hauv cov yeeb nkab.Yog hais tias cov yeeb nkab qhia tau hais tias tsawg ntom, steer clear!
3. Nco ntsoov xyuas cov cim lag luam.Reputed manufacturers ib txwm muab lawv cov cim lag luam ntawm lawv cov raj seamless.
4. Txheeb xyuas qhov chaw ntawm lub boiler raj.Ib tug zoo boiler raj yuav muaj ib tug du nto.Yog tias koj pom qhov chaw ntxhib thiab tsis sib xws, koj tuaj yeem paub tseeb tias qhov zoo tsis yog qhov cim.
