Ob chav -flange kav yog cov kav dej uas muaj flanges ntawm ob qho kawg hauv cov kav dej. Kuj feem ntau hu ua ob -coil kav los yog ob npaug - flange luv kav, lawv yog cov tub ntxhais txuas fittings hauv nroog, kev lag luam, thiab kev txuag dej.
I. Kev txhais thiab qauv
Ob qhov kawg ntawm cov yeeb nkab lub cev yog integrated tsim los yog welded flanges, ua tiav ib tug nruj kev twb kev txuas ntawm bolts thiab gaskets.
Tsis zoo li ib qho -flange thiab lub qhov (socket) pob qij txha, ob qhov kawg tuaj yeem txuas tau sai sai rau li qub, twj, thiab fittings.
Hom qauv: Cov yeeb nkab lub cev + flanges ntawm ob qho kawg + sealing nto + ntsia liaj qhov rooj qhov
II. Cov ntaub ntawv tseem ceeb thiab cov xwm txheej siv tau
Ductile Hlau Ob -Flanged Yeeb Nkab
Lub zog muaj zog, siab tawv, tiv thaiv -kev daws teeb meem, lub neej ua haujlwm ntev.
Feem ntau yog siv hauv cov dej hauv nroog, dej ntws, kev tiv thaiv hluav taws, thiab cov kav dej loj hauv cov kav dej hauv cov kav dej.
Carbon Steel / Steel Ob chav -Flanged yeeb nkab
Kev kub siab ua haujlwm, weldable, haum rau qhov kub thiab txias.
Siv nyob rau hauv roj av, tshuaj, cua sov, thiab industrial circulating dej systems.
Yas Coated / Anti-corrosion Ob Flanged Yeeb Nkab
Sab hauv thiab sab nraud tiv thaiv-corrosion txheej, tiv thaiv-scaling thiab tiv thaiv-corrosion.
Siv rau cov dej haus, corrosive chemical media, thiab kuv cov kua dej.
III. Qhov zoo
Txhim khu kev sib txuas:
Rigid flange foob, tus nqi xau yog qis dua li lub qhov (socket seal).
01
Yooj yim disassembly thiab sib dhos:
Tsis tas yuav txiav, yooj yim heev rau kev kho thiab hloov valve.
02
Strong adaptability:
Nws tuaj yeem txuas nrog cov kav dej, li qub, thiab cov cuab yeej ntawm cov khoom sib txawv.
03
Adaptable rau deformation:
Flexible foob tuaj yeem hloov kho rau lub hauv paus kev sib haum xeeb thiab thermal expansion thiab contraction.
04
High standardization:
Ua raws li cov qauv thoob ntiaj teb xws li ISO 2531, EN545, thiab GB.
05
IV. Tej kev siv
● Kev kho qhov ntev ntawm cov yeeb nkab, kev them nyiaj nyob deb
● Cov kav dej txuas nrog li qub, ntsuas dej, twj, thiab ntsuas ntsuas
● Kev sib txuas ntawm cov kav dej ntawm cov khoom sib txawv (cov yeeb nkab hlau ↔ steel yeeb nkab)
● Hluav taws kub hydrant, tshuaj xyuas zoo, cov khoom siv nkag thiab qhov hluav taws xob txuas
● Luv-cov kav dej nyob deb ntawm cov kav dej hauv cov kav dej, chav twj tso kua mis, thiab chav tsev khoom siv.
V. Cov ntsiab lus tseem ceeb ntawm Cov Qauv Kev Lag Luam
Kev ntsuas siab:
Feem ntau PN10/PN16/PN25
Nominal txoj kab uas hla:
Feem ntau siv DN50-DN1200
Txoj kev sealing:
Rubber Ring Seal + Flange Tightening - Ob Chav Tiv Thaiv
Qauv:
ISO 2531, EN545/598, GB/T 13295
VI. Kev lag luam Trends
Txhim kho kom muaj kev tiv thaiv corrosion siab, Lub neej ua haujlwm ntev, thiab kev soj ntsuam ntse
Optimized Flange Stress Grooves txo thermal expansion stress thiab txhim kho kev nyab xeeb
Integrated Casting thiab Weld-Dawb Corrosion Protection Txo Ntawm -Site Construction Hazards
