Qhov (socket) Vuam Flanges

Qhov (socket) Vuam Flangeshais txog lub flange qhov twg cov yeeb nkab kawg tau muab tso rau hauv flange nplhaib ntaiv thiab welded ntawm cov yeeb nkab kawg thiab sab nraud.Muaj ob hom: nrog caj dab thiab tsis muaj caj dab.Necked yeeb nkab flange muaj zoo rigidity, me me vuam deformation thiab sealing kev ua tau zoo, thiab yuav siv tau nyob rau hauv qhov teeb meem nrog siab ntawm 1.0 ~ 10.0MPa.

Sealing nto hom: RF, MFM, TG, RJ

Tus qauv tsim: ANSI B16.5, HG20619-1997, GB / T9117.1-2000-GB / T9117.4-200, HG20597-1997

Scope ntawm daim ntawv thov: Boiler thiab siab hlab ntsha, roj av, tshuaj lom neeg kev lag luam, shipbuilding, khw muag tshuaj, metallurgy, machinery, stamping luj tshib zaub mov thiab lwm yam lag luam.

Feem ntau siv hauv cov kav dej nrog PN ≤ 10.0MPa thiab DN ≤ 40.

Qhov zoo ntawm qhov (socket) vuam yeeb nkab fittings

1) Nws tsis tsim nyog rau prefabricate qhov zawj ntawm cov yeeb nkab.

2) Nws tsis yog qhov tsim nyog los ntsuas qhov chaw welds, vim tias cov fittings lawv tus kheej ua haujlwm rau lub hom phiaj ntawm calibration.

3) Cov khoom siv vuam yuav tsis nkag mus rau hauv cov yeeb nkab qhov.

4) Nws tuaj yeem hloov cov yeeb nkab threaded fittings, yog li txo qhov kev pheej hmoo ntawm to.

5) Fillet welds tsis haum rau kev kuaj hluav taws xob, yog li kev haum thiab vuam yog qhov tseem ceeb.Fillet welds feem ntau raug tshuaj xyuas los ntawm kev sim sib nqus particle thiab kev ntsuam xyuas penetrant.

6) Tus nqi tsim kho feem ntau yog qis dua li ntawm pob tw welded pob qij txha.Yog vim li cas yog qhov zawj sib dhos thiab zawj prefabrication tsis tas yuav tsum tau.

Disadvantages ntawm qhov (socket) vuam yeeb nkab fittings

1) Welders yuav tsum xyuas kom meej 1.6mm welding expansion qhov sib txawv ntawm cov yeeb nkab thiab lub xub pwg nyom thaum vuam.

2) Qhov muaj nyob ntawm cov kab nrib pleb hauv qhov sib txawv ntawm qhov sib txuas thiab lub qhov (socket weld) txo qhov corrosion tsis kam lossis hluav taws xob tsis kam ntawm cov kav dej.Thaum cov khoom sib sau ua ke ntawm lub qhov (socket) vuam pob qij txha, lawv tuaj yeem ua rau tsis ua haujlwm rau cov kav dej thiab kev saib xyuas.Nyob rau hauv rooj plaub no, tag nrho nkag mus pob tw welds feem ntau yuav tsum tau rau tag nrho cov yeeb nkab.

3) Lub qhov (socket) vuam tsis haum rau kev lag luam khoom noj khoom haus siab siab.Vim nws qhov kev nkag mus tsis tiav, muaj kev sib tshooj thiab cov kab nrib pleb, uas nyuaj rau kev ntxuav thiab tsim cov dej tsis tseeb.
