Cov lus qhia rau kev siv So (Socket Weld Flanges
Aug 25, 2025| Qhov (socket) weld flanges, raws li qhov tseem ceeb ntawm cov pipeline sib txuas, siab}}}}}} kub thiab txhim kho kev sib khi. Kev siv lub qhov (socket) weld flanges tsis tsuas yog txhim kho kev nyab xeeb system tab sis kuj txuas ntxiv lub neej. Cov lus qhia hauv qab no ua rau cov lus qhia tseem ceeb tau npog peb qhov tseem ceeb: installation, vuam, thiab txij nkawm.
Meej haum haum yuav tsum tau thaum lub sij hawm teeb tsa
Kev thev tes ntawm lub qhov (socket weld flange thiab cov yeeb nkab ncaj qha cuam tshuam cuam tshuam kev weld zoo. Ua ntej kev teeb tsa, nruj me ntsis tshawb xyuas ntawm Flange ID, feem ntau yog li ntawm 0.05-0.15mm, thiab ua kom ntseeg tau qhov tob ntawm tus qauv (feem ntau 1.25-1.5 zaug ntawm cov yeeb nkab phab ntsa thickness). Cov Flange Seem tsaws nto yuav tsum pub dawb ntawm khawb, roj stains, thiab lwm yam tsis xws luag. Zoo nkauj xuab zeb lossis cov neeg saib xyuas tu kom raug pom zoo. Rau cov hlau alloy lossis stainless hlau, kev saib xyuas yuav tsum tau ua kom tsis txhob muaj cov cuab yeej siv roj carbon steel.
Vuam cov txheej txheem yog qhov tseem ceeb
Vuam Vuam yog pom zoo siv GTAW (roj tungsten inert grant arc vuam), thiab tswj cov lus tawm thaum tshav kub los tiv thaiv kev deformation flatural. The preheating temperature should be adjusted according to the base material (for example, carbon steel generally does not require preheating, while chromium-molybdenum steel is recommended to be preheated to 150-200℃). Qhov vuam vuam yuav tsum yog ib qho zoo ib yam, thiab kev swb yuav tsum tau tshem txheej txheej los ntawm txheej thaum ntau txheej av vuam. Them nyiaj tshwj xeeb rau kev nkag mus ntawm lub hauv paus weld ntawm lub qhov (socket). Backfilling nrog Argon daim thaiv thaiv tuaj yeem txhim kho weld zoo.
Tu thiab daws teeb meem
Nquag xyuas cov nruj ntawm cov flange bolts. Nws raug nquahu kom nruj lawv hauv kab pheeb ces kaum kev txiav txim, siv qhov tseem ceeb raws li cov khoom siv specifications. Yog tias micro - Kev twv Txawm li cas los xij, kev quab yuam nruj nruj nyob rau hauv kev kub siab yog nruj me ntsis txwv. Rau cov ntawv thov nrog cov kev tsim tawm ntau, flange tsim nrog cov thawj tus thawj coj tau pom zoo kom txo cov khoom siv vuam.
Mastering Cov tswv yim saum toj saud tuaj yeem txhim kho kev ntseeg tau ntawm lub qhov (socket) {}}} welded flanges. Hauv cov ntawv thov tiag tiag, cov txheej txheem tsis yuav tsum tau hloov kho raws li cov haujlwm tshwj xeeb (xws li kev ntsuas siab PN16-PN40 thiab corrosive media). Sab laj tus kws tshaj lij kws ua haujlwm rau kev daws teeb meem yog tsim nyog.
