Steel flange piping yog ib txoj kev sib txuas tseem ceeb hauv cov kav dej, dav siv rau cov khoom siv thiab cov kav dej sib txuas hauv cov ntawv thov kev lag luam. Nrog nws cov qauv txhim khu kev qha thiab yooj yim disassembly, nws ua kom muaj kev nyab xeeb thiab kev thauj mus los nruab nrab. Tom qab vuam thiab tsim nyob rau hauv lub Hoobkas, nws yooj yim rau kev tsim kho kev ua haujlwm thaum tswj cov kev cai thiab kev ncaj ncees ntawm cov welds.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, steel flanged piping yog haum rau ntau yam kev ua hauj lwm. Raws li cov qauv xws li Asmeskas ASME B16.5 thiab European EN1092-1, nws cov nominal siab ntau yam npog PN0.25 txog PN42, muaj feem xyuam rau cov tshuab los ntawm qis rau ultra{11}}siab siab. Cov yeeb nkab txoj kab uas hla ntawm DN10 txog DN3000 thiab siab dua, ua tau raws li qhov yuav tsum tau ua los ntawm cov kav dej me me mus rau cov kav dej loj loj. Nws yog dav siv hauv cov tshuab xws li roj av, roj av, tshuaj lom neeg, hluav taws xob, dej hauv nroog thiab kev tso dej, thiab kev kho dej phwj tuaj. Tshwj xeeb tshaj yog nyob rau hauv siab - kub (txog 800 degree), qis- kub (tsawg li -196 degree), corrosive media (xws li cov kua qaub thiab alkaline ib puag ncig), los yog kev thauj mus los ntawm cov tshuaj lom neeg thiab cov nplaim hluav taws xob / tawg tawm, stainless hlau (xws li 3 3 6L, RF alloy) TG, los yog RJ sealing ntsej muag, tuaj yeem ua kom muaj kev sib khi thiab kev nyab xeeb. Raws li cov kev cai, steel flanged piping yuav tsum ua raws li cov qauv nruj. Ua ntej, cov khoom siv yuav tsum ua kom tau raws li cov qauv tsim, nrog carbon steel, alloy steel, lossis stainless hlau uas yuav tsum muaj cov khoom siv sib xws thiab kev tiv thaiv corrosion. Thib ob, flange hom xws li pob tw-weld flanges (WN), plam- ntawm flanges (SO), thiab threaded flanges (TH) yuav tsum raug xaiv kom tsim nyog raws li kev ntsuas siab thiab kev sib txuas. Butt-weld flanges yog haum rau siab-siab tshuab, thaum plam-ntawm flanges yog qhov zoo tagnrho rau qis-siab, me-inch scenarios. Rau sealing, haum gaskets xws li hlau kauv-qhov txhab gaskets, asbestos roj hmab gaskets, los yog PTFE gaskets yuav tsum tau siv los xyuas kom meej flange flange lub ntsej muag sib cuag thiab tiv thaiv kom txhob xau. Kev sib txuas bolts yuav tsum tau nruj nruj kom ua tau raws li qhov yuav tsum tau ua ntej, kom ntseeg tau tias kev sib khi ruaj khov.
Tsis tas li ntawd, kev tsim khoom thiab kev tshuaj xyuas yuav tsum ua raws li cov qauv hauv lub tebchaws, suav nrog kev ua kom ntev ntev, qhov zoo ntawm cov txheej txheem vuam, thiab kev ntsuas siab. Cov flanges yuav tsum tau kuaj pom qhov muag, ntsuas qhov ntev, thiab tsis yog- kuaj kev puas tsuaj kom tsis muaj kab nrib pleb, qhov pores, lossis lwm yam tsis xws luag. Cov khoom lag luam yuav tsum tau nrog cov ntawv pov thawj zoo thiab ua kom pom tseeb nrog cov ntaub ntawv tsim khoom, cov khoom siv, lub siab nominal, thiab lwm yam ntsiab lus rau traceability thiab txais. Hlau flanged piping, nrog nws cov kev siv dav thiab kev ntseeg siab, tau dhau los ua ib qho kev sib txuas tsis tseem ceeb hauv cov kav dej niaj hnub. Nws daim ntawv thov txheej txheem thiab tswj tau ua lub hauv paus tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
