Stainless hlau lub luj tshib muaj cov khoom siv zoo heev thiab lub cev, nrog rau cov dej tsis kam, tiv thaiv corrosion, thiab siab ua haujlwm. Cov yam ntxwv no ua rau lawv haum rau kev siv ntau yam. Lawv cov yam ntxwv zoo thiab qhov zoo tau ua rau lawv qhov kev txhawb nqa thiab kev txhim kho txuas ntxiv, ua kom pom tseeb tias lawv muaj txiaj ntsig thiab ua tau zoo hauv kev tsim kho yam tsis muaj kev cuam tshuam zoo.
Thawj kauj ruam hauv cov txheej txheem yog ntsuas thiab txiav cov khoom siv raw cov kav dej. Peb xam qhov kev ncua deb ntawm qhov chaw ntawm cov khoom mus rau lub ntsej muag kawg, thiab tom qab ntawd muab lawv tso rau ntawm lub tshuab dhos kom raug txiav.
Tom ntej no, peb siv tshauv rau cov kav dej txiav. Cov txheej txheem no ua raws li cov roj nplua nyeem los xyuas kom meej qhov zoo nkauj ntawm qhov chaw sab nrauv ntawm cov yeeb nkab fittings. Yog tsis muaj kev siv cov hmoov tshauv, pom cov streaks yuav tshwm sim ntawm qhov chaw ntawm cov yeeb nkab fittings.
Tom qab cov yeeb nkab yog ashed, cov kauj ruam tom ntej yog nias, uas tuaj yeem ua tiav siv mandrel thawb lossis pob thawb.
Tom qab ntawd, lub luj tshib undergoes annealing, qhov twg nws yog rhuab mus rau ib tug tej yam kub thiab khaws cia ntawm qhov kub thiab txias rau ib lub sij hawm ntawm lub sij hawm ua ntej tso cai kom txias maj mam. Annealing yog ib qho tseem ceeb hauv kev txiav txim siab qhov zoo ntawm lub luj tshib tom qab tsim. Nws txhim kho cov cuab yeej cuab tam ntawm lub luj tshib kub thiab txo qis kev ntxhov siab. Tsis tas li ntawd, nws txo qis hardness, txhim kho plasticity thiab toughness, thiab txhim kho kev ua haujlwm thiab txiav kev ua haujlwm.
Cov kauj ruam tom ntej yog pickling. Kev tiv thaiv corrosion ntawm stainless hlau yeeb fittings feem ntau yog los ntawm cov tshuaj tiv thaiv ntawm chromium nyob rau hauv cov hlau nrog oxygen, uas tsim ib tug tuab tiv thaiv txheej ntawm qhov chaw. Lub hom phiaj ntawm pickling yog pib qhov tshuaj tiv thaiv ua ntej, yog li txhim kho corrosion kuj ntawm stainless hlau yeeb fittings. Tsis tas li ntawd, cov txheej txheem pickling tshem tawm cov roj thiab lwm yam khoom uas tej zaum yuav muaj kab mob ntawm cov yeeb nkab thaum lub sij hawm tsim khoom.
Tom qab pickling, cov khoom yog tag nrho polished siv txhua yam, tshuaj, los yog electrochemical txoj kev los txo cov nto roughness ntawm lub workpiece, uas ua rau ib tug kaj thiab du tiav.
Thaum kawg, xuab zeb dov kev kho mob yog siv, qhov twg cov yeeb nkab fittings yog huv si sanded, thiab saum npoo ntawm cov khoom yog ntxuav kom tshem tawm burrs. Cov txheej txheem no tseem yuav pab tshem tawm cov xeb ntawm qhov chaw.
Tom qab pickling, peb cov khoom tau dhau los ua tus txheej txheem thib ob txhawm rau txhim kho corrosion kuj thiab ua tau raws li lub Hoobkas nruj.
Thaum kawg, chamfering yog ua. Chamfering tshem tawm burrs tshwm sim los ntawm machining thiab pab txhawb kev sib dhos ntawm cov khoom los ntawm kev tsim cov npoo beveled ntawm qhov kawg ntawm cov khoom.
Kev tsim thiab ua cov yeeb nkab stainless hlau fittings tau ua tiav hauv txoj kev no. Peb zoo siab tos txais txhua tus neeg siv khoom txaus siab los nug txog peb cov khoom.
