Zoo li cov ntaub npog hlau ruaj khov hlau, lawv tuaj yeem pom nyob hauv ntau yam tsim, tsa, concave thiab convex, thiab zawj surfaces. Tsis zoo li Taub Hau Vuam flanges, dig muag flanges tsis muaj caj dab. Cov khoom siv no feem ntau siv thaum kawg ntawm dej muab cov kav teb kav cov kav teb, kom ua kom tsis muaj kev cuam tshuam los yog cuam tshuam.
Nqe 2: Tshawb nrhiav qhov muag tsis pom kev cov qauv
Dig muag flanges ua raws li cov qauv tsim khoom tshwj xeeb kom ntseeg tau tias zoo, raws li kev cai, thiab kev sib haum xeeb, thiab sib xyaw. Cov qauv koob hmoov nyob rau hauv kev lag luam suav nrog ANSI B16.5, DIN2576, LEG20605-1: 1992, HG20605-1: 19926-1996, GB / T9123.1 ~ 9123.4- 2000, JB / T86.1 ~ 86.2-1994. Txhua tus qauv txheej txheem ntau yam ntawm cov dig muag flanges, xws li qhov ntev, cov khoom yuav tsum tau, kev ntsuas siab, thiab cov txheej txheem ntsuas. Nws yog qhov tseem ceeb los sab laj txog cov qauv tshwj xeeb uas cuam tshuam rau koj qhov kev pom zoo nkauj ntawm Flarge kev ua tau zoo thiab sib xyaw nrog koj cov raj xa hluav taws xob.
Nqe 3: Kev tsis paub cov hlau qib uas siv rau hauv qhov muag tsis pom Flarge
Kev xaiv ntawm cov qauv steel ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom muag dig muag, vim tias nws cuam tshuam ncaj qha, thiab tiv taus corrosion. Ntau cov qauv steel tau ua haujlwm hauv qhov muag tsis pom Flarge cov tuam tsev, suav nrog tab sis tsis txwv rau:
1. Carbon Steel: kev xaiv zoo nqi nrog lub zog zoo thiab tiv taus rau cov kub. Tib neeg cov hom phiaj roj carbon me nyuam siv yog ASTM A105, ASTM A350 LF2, thiab ASTM A516 Gr. 70.
2. Tus hlau stainless: zoo tagnrho rau cov ntawv thov uas corrosion kuj yog qhov tseem ceeb heev. Nrov stainless hlau grades suav nrog ANTM A182 F304 / F304L, ASTM A182 F316 / F316L, thiab AVEX A182 F321 F321 F321 F321.
3. Alloy Steel: cov qib steel txhim kho cov neeg dig muag flange qhov tsis kam mus rau cov kev ntxhov siab tshwj xeeb, xws li muaj kev ntxhov siab lossis thaj chaw uas muaj huab cua. Cov qib tag kis tau siv yog ASTM A182 F5, ASTM A182 F9, thiab AUTM A182 F91.
Nws yog qhov tseem ceeb los xaiv cov qauv hlau tsim nyog raws li koj cov phiaj xwm, xav txog yam xws li ib puag ncig ua haujlwm, siab, thiab tshuaj lom neeg.
Nqe 4: Ua kom muaj txiaj ntsig zoo thiab ua raws li qhov muag tsis pom kev
Thaum tus neeg dig muag flanges, nws yog qhov tseem ceeb kom ntseeg tau tias lawv ua raws cov qauv tsim khoom thiab cov ntawv pov thawj zoo. Nrhiav cov npe nrov uas ua rau cov txheej txheem tsim nruj, ua kom lawv cov dig muag uas tau sib ntsib lossis ntau tshaj kev lag luam. Ib qho ntxiv, txiav txim siab cov neeg xa khoom uas muab daim ntawv pov thawj ntsuas cov ntaub ntawv (MTC) rau kev tswj hwm zoo. Cov ntaub ntawv no puas tau siv tau tias cov neeg dig muag tsis pom kev ua haujlwm tau txais kev sim tsim nyog, lav lawv txoj kev haum rau koj qhov project.
Nqe 5: Qhov Kawg thiab Cov Lus Taw Qhia Zaum Kawg
Qhov muag dig muag Flanges, tseem hu ua flange npog lossis qhov muag tsis pom, yog qhov tsis pom kev ntawm cov yeeb nkab. Lawv cov khoom tsim ntau lawm rau cov qauv tshwj xeeb los xyuas kom meej tias kev sib raug zoo thiab sib xyaw. Renowned cov qauv tsim khoom xws li Ansi B16.5, Din, JIS, thiab BS, thiab BS, thiab cov khoom yuav tsum tau ua, thiab cov kev ntsuas siab. Ntxiv mus, cov qhab nia steel xws li cov hlau carbon, hlau hlau, thiab aluminoy hlau, thiab cov hlau aluminoy tau xaiv kom ntseeg tau zoo thiab ua kom ntev. Thaum tus neeg dig muag flanges, ib txwm xaiv cov npe nrov npe uas ua ntej zoo thiab muab cov ntawv pov thawj tsim nyog. Los ntawm kev nkag siab cov qauv dig muag nrog cov qauv khoom siv thiab cov hom qauv hlau, koj tuaj yeem ntseeg siab xaiv cov khoom siv rau koj lub raj hluav taws xob, ua haujlwm kom muaj txiaj ntsig zoo thiab nyab xeeb.
