Weld caj dab flange (WN flange)yog ib hom flange nrog lub caj dab ntev, tapered caj dab (hub) uas txuas los ntawm flange puag. Lub caj dab ntawm flange muab kev txhawb zog rau kev sib txuas thiab ua kom yooj yim hloov pauv ntawm flange mus rau cov yeeb nkab. Weld caj dab flanges yog welded rau cov yeeb nkab, tsim kom muaj kev sib txuas ruaj khov thiab ruaj khov. Lawv feem ntau yog siv nyob rau hauv high-pressure thiab high-temperature piping systems, qhov twg kev ntseeg tau thiab tsis kam yog qhov tseem ceeb.
Ntawm qhov tod tes,Ntev Weld caj dab flange (LWN flange)yog ib qho kev hloov pauv ntawm lub caj dab weld flange nrog lub caj dab txuas ntxiv (chim) piv rau tus qauv weld caj dab flange. Lub caj dab ntev ntawm lub caj dab ntev weld flange muaj kev txhawb nqa ntxiv thiab hloov tau yooj yim hauv kev tsim cov kav dej. Ntev weld caj dab flanges feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj qhov chaw ntxiv rau kev rwb thaiv tsev, ntsuas, lossis nkag mus rau cov kav dej. Lawv feem ntau pom muaj nyob rau hauv cov hluav taws kub exchangers, cov hlab ntsha siab, thiab cov reactors, qhov twg flange yuav tsum tau txuas mus rau ib tug protruding los yog recessed yeeb nkab kawg.
Common Specifications:
ANSI/ASME B16.5: Cov qauv no suav nrog qhov ntev, qhov ntsuas kub-kub, cov ntaub ntawv, thiab kev kam rau siab rau Weld Neck Flanges hauv qhov ntau thiab tsawg NPS 1/2 txog NPS 24.
ASME B16.47: Cov qauv no suav nrog ob lub koob - Series A (MSS SP-44) thiab Series B (API 605) - npog loj txoj kab uas hla Weld Neck Flanges thiab dig muag Flanges. Series A flanges hnyav dua thiab muaj lub voj voog loj dua qub piv rau Series B flanges.
Weld Neck Flanges thiab Ntev Weld Neck Flanges yog ob hom flanges feem ntau siv hauv cov kav dej, tab sis lawv muaj qhov sib txawv ntawm lawv qhov tsim, kev siv, thiab kev siv. Nov yog qhov kev sib piv ntxaws:
Weld caj dab Flanges:
1. Tsim:
- Weld Neck Flanges muaj qhov ntev tapered hub uas muab kev txhawb zog rau lub flange thiab ua kom yooj yim hloov ntawm cov yeeb nkab mus rau flange.
2. Daim ntawv thov:
- Weld Neck Flanges feem ntau yog siv rau hauv high-pressure thiab high-temperature daim ntaub ntawv uas lub flange yuav raug rau cov loads tseem ceeb thiab kev nyuaj siab.
3. Vuam:
- Cov flanges no yog welded rau cov yeeb nkab, muab kev sib txuas ruaj khov thiab ruaj khov. Lub vuam ua kom muaj kev sib tsoo-pov thawj thiab txhim kho cov txheej txheem kev ncaj ncees ntawm kev sib koom ua ke.
4. Kev sib tw:
- Vim tias lawv tsim, Weld Neck Flanges ua kom zoo sib xws ntawm cov ntsia hlau qhov, uas yooj yim rau kev teeb tsa thiab txo qhov kev pheej hmoo ntawm kev sib tsoo thaum sib dhos.
5. Kev ntsuas siab:
- Weld Neck Flanges muaj nyob rau hauv ntau qhov kev ntsuas siab thiab qhov ntau thiab tsawg kom haum rau cov kav dej sib txawv.
Ntev Weld Neck Flanges:
1. Tsim:
- Ntev Weld Neck Flanges muaj lub caj dab txuas ntxiv lossis lub thoob, muab kev txhawb nqa ntxiv thiab tso cai rau kev vuam yooj yim rau cov yeeb nkab. Qhov ntev ntawm lub caj dab feem ntau ntev dua piv rau tus qauv Weld Neck Flanges.
2. Daim ntawv thov:
- Ntev Weld Neck Flanges feem ntau yog siv rau hauv cov ntawv thov uas xav tau kev txhawb nqa ntxiv, xws li nyob rau hauv high-pressure, high-temperature, los yog corrosive ib puag ncig.
3. Vuam:
- Zoo ib yam li Weld Neck Flanges, Ntev Weld Neck Flanges yog welded rau cov yeeb nkab. Lub caj dab txuas ntxiv muab qhov chaw vuam ntau dua, uas txhim kho lub zog thiab kev ncaj ncees ntawm kev sib koom tes.
4. Flexibility:
- Ntev Weld Neck Flanges muab kev yooj yim dua nyob rau hauv cov nqe lus ntawm kev sib dhos thiab qhov chaw piv rau tus qauv Weld Neck Flanges. Lawv tuaj yeem siv rau hauv cov ntawv thov uas cov yeeb nkab yuav tsum tau tsa lossis txo qis rau kev sib tw.
5. Cov ntawv thov tshwj xeeb:
- Ntev Weld Neck Flanges feem ntau yog siv rau hauv cov ntawv tshwj xeeb, xws li hauv cov khoom siv hluav taws xob, cov hlab ntsha siab, thiab cov reactors, qhov twg flange yuav tsum tau txuas mus rau cov yeeb yaj kiab los yog recessed kawg.
Hauv cov ntsiab lus, thaum ob qho tib si Weld Neck Flanges thiab Ntev Weld Neck Flanges yog siv rau cov ntawv thov kev kub siab thiab cov khoom siv vuam rau cov yeeb nkab, Ntev Weld Neck Flanges muab kev txhawb zog ntxiv thiab ua kom yooj yim, ua rau lawv tsim nyog rau cov ntawv tshwj xeeb uas xav tau kev txhawb nqa ntxiv thiab kev sib dhos precision.
