Lub zog tensile zog ntawm ANSI-certified flange pab rau kev ua tau zoo ntawm cov tshuab tshuab, cov qauv, thiab cov rooj sib txoos thoob plaws hauv Tebchaws Meskas thiab thoob ntiaj teb. ANSI Class Flanges muaj lub koom haum foob kev pom zoo rau cov hauj lwm nyuaj tshaj plaws txij li thaum lawv tau raug sim thiab ntawv pov thawj kom ua tau raws li cov qauv ntawm American National Standards Institute.
Lub koom haum American National Standards Institute tau tsim nyob rau xyoo 1918 thiab muaj nws lub tsev hauv paus hauv Washington, DC Nws tau suav hais tias yog lub koom haum hauv Tebchaws Meskas lub luag haujlwm rau kev saib xyuas cov qauv hauv tebchaws thiab kev ntsuas kev ua raws li cov khoom, kev pabcuam, txheej txheem, tshuab, thiab cov neeg ua haujlwm.
ANSI koom tes nrog tsoomfwv Asmeskas cov koom haum thiab cov koom haum nrog rau cov koom haum thoob ntiaj teb los ua ANSI cov qauv siv thoob ntiaj teb.
Ua ntej tsim ANSI, engineering thiab cov qauv khoom xws li flanges tau tsim los ntawm American Institute of Electrical Engineers (AIEE lossis IEEE), American Society of Mechanical Engineers (ASME), American Institute of Mining, Metallurgical, thiab Petroleum Engineers (AIME), American Society of Civil Engineers (ASCE), thiab American Society for Testing and Materials (ASTM International) ua tswv cuab ntawm United Engineering Society, los yog UES.
ANSI B16.5
ANSI B16. Nws suav nrog cov kev ntsuas thiab cov qauv rau cov yam ntxwv hauv qab no, tau teev nyob rau hauv ob qho tib si metric thiab English units ntawm kev ntsuas:
Kev ntsuas kub-siab
Khoom siv
Tolerances
Qhov ntev
Kos npe
Kev sim
Cov txheej txheem ntawm kev xaiv qhov qhib
ANSI tus qauv qhov ntev rau flanges yog 150, 300, 400, 600, 900, 1500, thiab 2500 hauv qhov ntau thiab tsawg NPS 1/2 rau NPS 24.
ANSI Flange CLASS HOM
Flanges feem ntau yog tsim los kaw, npog, koom, lossis txhawb nqa cov kav dej, tsis hais qhov loj lossis qhov tshwj xeeb. Cov no yog 6 hom ntawm ANSI Class Flanges:
Ntiv nplhaib thiab hub-style slip-ons tsim kom haum rau hauv cov yeeb nkab.
Weld caj dab, tsim kom haum rau sab hauv txoj kab uas hla ntawm cov yeeb nkab ces welded rau nws.
Sealing qhov kawg lossis aperture ntawm cov kav dej lossis lub nkoj uas tsis pom kev.
Lap sib koom siv ua ke nrog stub kawg fittings rau daim ntaub ntawv yuav tsum tau disassembly
Yog tsis muaj qhov yuav tsum tau rau welding, threaded kom haum externally threaded kav.
Qhov (socket)-weld, kom muaj kev pom zoo sab hauv ntws los ntawm lub qhov (socket) haum thiab sab saum toj weld
MATERIAL GRADES THIAB PERMANCE
Cov khoom siv ntau tshaj plaws rau ANSI Class Flanges yog forged lossis cam khwb cia, tshwj tsis yog muaj lwm yam sau tseg.
Kev lag luam thiab daim ntawv thov
Hauv kev lag luam hauv tsev thiab thoob ntiaj teb, ANSI cov qauv rau flanges muaj npe nrov rau lawv lub zog thiab lub neej ntev. Tej sectors thiab kev siv xws li:
Kev ua zaub mov thiab kev tsim khoom (ANSI-NSF yog ib tsev neeg muaj kev nyab xeeb ntawm cov khoom noj tshwj xeeb)
Valves, hlab ntsha, thiab cov twj tso kua mis
municipal waterworks thiab yeeb nkab systems
Thermostats thiab kub exchangers
Mechanical thiab kav dej systems
Kev tiv thaiv los ntawm kev pabcuam hluav taws
Lub zog cog thiab nuclear zog kev lag luam
Petroleum, gas, thiab chemical compounds
ANSI B15.5 SO
Hu rau SSM cov neeg ua haujlwm tam sim ntawd rau cov ntaub ntawv ntxiv ntawm ANSI Class Flanges thiab kev cai flanges ua kom tau raws li cov kev cai tshwj xeeb.
