Kev faib tawm ntawm Boiler Pipes los ntawm Hom
Cov kav dej boiler tuaj yeem faib dav dav raws li kev tsim khoom thiab kev pabcuam. Seamless boiler kav yog feem ntau siv nyob rau hauv siab - siab thiab siab - qhov kub thiab txias ib puag ncig vim lawv cov qauv tsis sib xws thiab tsis muaj weld seams. Cov kav dej no feem ntau yog tsim los ntawm cov txheej txheem kub dov lossis txias txheej txheem, kom ntseeg tau tias cov khoom siv zoo ib yam thiab muaj kev ntseeg siab.
Welded boiler kav, suav nrog ERW thiab SAW hom, feem ntau yog siv rau hauv kev siv qis qis uas tus nqi ua haujlwm yog qhov tseem ceeb. Txawm hais tias kev siv thev naus laus zis niaj hnub no tau txhim kho lawv cov kev ua tau zoo, lawv tseem tsis tshua muaj nyob hauv qhov tseem ceeb ntawm - siab boiler systems. Alloy boiler kav, feem ntau muaj chromium thiab molybdenum, tshwj xeeb tshaj yog tsim los rau siab - qhov kub thiab txias kev pab cuam qhov creep kuj thiab oxidation stability yog qhov tseem ceeb. Tsis tas li ntawd, cov khoom siv hluav taws xob hloov hluav taws xob sawv cev rau ib pawg tshwj xeeb, tsom mus rau kev hloov pauv hluav taws xob zoo dua li kev tswj hwm lub siab.
Ntsiab Specifications thiab Standard Requirements
Boiler yeeb nkab specifications yog txhais los ntawm thoob ntiaj teb cov qauv xws li ASTM, ASME, EN, thiab GB, uas tsim kom muaj cov kev cai rau cov tshuaj muaj pes tsawg leeg, mechanical zog, thiab dimension tolerances. Cov kev qhia tshwj xeeb no ua kom ntseeg tau tias cov kav dej tuaj yeem ua tau raws li qhov xav tau.
Cov tsis tseem ceeb muaj xws li sab nraud txoj kab uas hla, phab ntsa thickness, ntev, thiab permissible deviation ranges. Rau siab - cov ntawv thov siab, yuav tsum muaj kev zam nruj dua los tswj cov kev ntxhov siab sib xws. Cov khoom siv qib xws li ASTM A106, ASTM A192, thiab cov qib alloy zoo li ASTM A213 T11 thiab T22 feem ntau siv, txhua qhov muab cov yam ntxwv sib txawv nyob ntawm qhov kub thiab txias.
Ntxiv nrog rau qhov loj me thiab cov khoom siv tshwj xeeb, cov qauv kuj tseem txheeb xyuas cov txheej txheem xws li kev sim hydrostatic, tshuaj xyuas ultrasonic, thiab kev txheeb xyuas cov cuab yeej cuab tam.

Kev xaiv cov khoom siv thiab cov yam ntxwv ua haujlwm
Kev xaiv cov khoom siv yog ib qho tseem ceeb tshaj plaws ntawm kev tsim cov yeeb nkab boiler. Cov yeeb nkab carbon steel feem ntau yog siv rau nruab nrab kub thiab siab daim ntawv thov vim lawv lub zog zoo thiab tus nqi -kev ua tau zoo. Txawm li cas los xij, raws li kev khiav hauj lwm kub nce, alloy steels yuav tsum tau tswj xyuas txhua yam kev ncaj ncees.
Chromium txhim kho oxidation tsis kam, thaum molybdenum txhim khu lub zog nkag, ua Cr-Mo alloy steels zoo tagnrho rau siab - kub boiler systems. Cov ntaub ntawv no yog tsim los tiv thaiv ntev - lub sij hawm deformation thiab tswj cov txheej txheem stability nyob rau hauv tas li thermal stress. Qhov sib npaug ntawm lub zog, ductility, thiab toughness yog ua tib zoo tswj kom tsis txhob ua tsis tiav thaum lub sijhawm ua haujlwm.
Cov txheej txheem kev kho cua sov xws li normalizing, quenching, thiab tempering yog siv los ua kom zoo dua microstructure ntawm cov hlau. Cov txheej txheem no kho cov nplej loj thiab txhim kho cov khoom siv kho tshuab, kom ntseeg tau tias cov kav dej ua tau raws li qhov xav tau ntawm kev siv boiler.
Cov txheej txheem tsim khoom thiab kev tswj xyuas zoo
Cov txheej txheem tsim khoom ntawm cov kav dej boiler ncaj qha cuam tshuam rau lawv cov kev ua tau zoo thiab kev ntseeg tau. Seamless kav yog tsim los ntawm kev tho cov khoom siv ua raws li dov los yog kos duab, ua rau cov qauv zoo sib xws uas tsis muaj qhov tsis xws luag. Qhov no ua rau lawv tshwj xeeb tshaj yog haum rau kev siv siab -siab.
Welded kav, ntawm qhov tod tes, yog tsim los ntawm steel daim hlau los yog coils thiab koom siv cov txheej txheem vuam siab heev. Thaum lawv muab cov txiaj ntsig zoo hauv cov nqi thiab kev tsim khoom, kev tswj xyuas nruj yog yuav tsum tau ua kom muaj kev ncaj ncees weld. Tsis yog-kev kuaj kev puas tsuaj xws li kev tshuaj xyuas ultrasonic thiab radiographic yog siv los kuaj xyuas qhov tsis xws luag.
Kev tswj xyuas kev ua tau zoo txuas ntxiv dhau ntawm kev tsim khoom kom suav nrog kev tshuaj xyuas cov khoom siv raw, kev saib xyuas cov txheej txheem, thiab kev sim cov khoom kawg. Txhua theem yuav tsum ua raws li cov qauv tsim nyog los xyuas kom meej tias cov kav dej tiav ua tau raws li qhov xav tau ntawm kev ua haujlwm. Cov neeg tsim khoom uas muaj peev xwm ua tau zoo tshaj plaws thiab cov ntawv pov thawj yog qhov zoo dua los xa cov khoom lag luam zoo ib yam thiab txhim khu kev qha.
Daim Ntawv Thov Scenario hauv Kev Lag Luam Niaj Hnub No
Boiler kav yog siv nyob rau hauv ntau yam kev lag luam daim ntaub ntawv, txhua yam uas yuav tsum tau ua hauj lwm. Hauv kev tsim hluav taws xob, lawv yog qhov tseem ceeb rau kev tsim hluav taws xob thiab hloov hluav taws xob hauv boilers thiab superheaters. Hauv kev lag luam petrochemical, lawv tau siv rau hauv cov txheej txheem cua sov thiab cov reactors uas muaj qhov kub thiab txias.
Tsis tas li ntawd, cov kav dej boiler tau siv rau hauv cheeb tsam cua sov thiab cov boilers muaj, qhov kev ntseeg siab thiab kev ua haujlwm tseem ceeb heev. Qhov kev xaiv ntawm cov yeeb nkab hom thiab cov khoom siv yog nyob ntawm cov yam ntxwv xws li kev ua haujlwm kub, siab, thiab ib puag ncig. Kev xaiv kom raug ua kom pom kev ua tau zoo thiab txo qis kev saib xyuas.
