Cov ntsiab lus tseem ceeb rau kev sib txuas ntawm Flange
Taw qhia:
Flanges feem ntau siv cov khoom siv hauv cov kav dej loj loj, ua haujlwm rau lub hom phiaj ntawm kev sib txuas ntawm ob qhov kawg ntawm cov kav dej los ntawm qhov hu ua flange kev sib txuas. Cov kev sib txuas no yog qhov tseem ceeb rau kev ua kom cov kav dej tsis muaj paug, xav tau qee yam kev cai. Tab sis li cas flange kev sib txuas ua tau, thiab dab tsi yuav tsum tau xav txog thaum lub sij hawm kev sib txuas? Wb delve rau hauv cov yam.
I. Flange Connection Methods
1. Flat Welding: Txoj kev no tsuas yog siv cov txheej txheem vuam nkaus xwb uas tsis tas yuav tsum tau vuam ntawm txheej sab hauv. Nws yog tsim rau kev sib txuas cov kav dej nrog cov nominal siab hauv qab 2.5 MPa. Flat vuam flanges tuaj nyob rau hauv peb hom: du, concave-convex, thiab tus nplaig-thiab-groove. Ntawm cov no, cov flanges du yog siv dav tshaj plaws vim lawv cov txiaj ntsig zoo.
2. Butt Vuam: Butt welding necessitates welding ob sab hauv thiab txheej txheej ntawm flange, ua rau tsis sib xws flange vuam. Txoj kev no yog qhov nyuaj, suav nrog cov nqi zog ntau dua, kev teeb tsa tsis yooj yim, thiab cov nqi siab dua rau cov khoom siv. Nws yog feem ntau ua hauj lwm rau nruab nrab mus rau high-pressure pipelines nrog nominal pressures li ntawm 0.25 mus rau 2.5 MPa.
II. Cov ntsiab lus tseem ceeb rau kev sib txuas ntawm Flange
Txawm hais tias qhov tshwj xeeb flange kev sib txuas txoj kev siv, lawv qhia qee cov qauv kev qhia. Qhov nruab nrab nruab nrab ntawm cov raj xa dej thiab cov flange yuav tsum nyob rau tib theem kab rov tav, kom ntseeg tau tias 90-degree ntsug alignment ntawm qhov chaw sib txuas.
Rau flanges nrog ntau txoj kev sib txuas, kev xaiv gasket zoo ib yam yog qhov tseem ceeb los pab txhawb kev hloov pauv yooj yim dua thaum saib xyuas nyob rau hauv cov kev ntxhov siab zoo sib xws. Gaskets yuav tsum raug xaiv kom ze rau qhov tsawg dua li qhov ua tau.
III. Flange Connection Paub meej
Yuav Tsum Tau: Xyuas kom tseeb tias cov flanges, bolts, thiab gaskets ua tau raws li cov qauv teev tseg. Lub sealing nto yuav tsum du thiab huv si, tsis muaj burrs. Bolts thiab screws yuav tsum ua kom tiav yam tsis muaj qhov khoob. Cov khoom siv gasket yuav tsum yog mos thiab tiv taus kev laus. Txhua qhov chaw ntawm cov khoom yuav tsum tsis txhob muaj cov kab nrib pleb thiab yuav tsum tau ua kom huv si ua ntej sib sau cov flanges. Yuav tsum tsis muaj cov kab mob ntawm cov roj paug.
IV. Sib dhos Flanges
Qhov yuav tsum tau muaj: Lub flange npog yuav tsum yog perpendicular mus rau nruab nrab ntawm lub raj xa dej, nrog rau tib cov kev taw qhia ntawm bolt installation rau flanges ntawm tib specification. Qhov kev ncua deb ntawm qhov kev txhawb nqa yeeb nkab flange thiab cov phab ntsa sab nrauv yuav tsum tshaj 100mm, thaum qhov kev ncua deb ntawm lub tsev phab ntsa yuav tsum tshaj 200mm. Flanges faus ncaj qha rau hauv av yog raug rau corrosion thiab yuav tsum tau tiv thaiv corrosion.

Flanges ua lub luag haujlwm tseem ceeb hauv cov kav dej, thiab kev xaiv ntawm txoj kev sib txuas tsim nyog tau cuam tshuam los ntawm ntau yam, suav nrog cov khoom siv, cov ces kaum, thiab cov txheej txheem tsim khoom. Ua raws li cov kev xav tau ua kom ntseeg tau qhov zoo ntawm flange Cheebtsam, suav nrog kev xav zoo li beveled xaus, kho qhov chaw, thiab ntim. Cov txheej txheem tsim nyog rau kev tsim cov flanges yog qhov tseem ceeb rau kev tsim cov khoom zoo.
Hauv kev tsim cov raj xa dej, qhov chaw sib txawv yuav xav tau ntau hom flanges. Piv txwv li, ib puag ncig corrosive heev yuav tsum tau siv cov stainless hlau flanges rau lawv superior corrosion kuj. Qhov kev paub no tuaj yeem coj cov kev xaiv ntawm flange Cheebtsam rau cov ntawv thov tshwj xeeb.
SINO SPECIAL METAL yog ib qho kev ntseeg siab ntawm cov kav dej, flanges, thiab fittings. Peb zoo siab tos txais cov lus nug thiab kev yuav khoom, muab cov khoom lag luam thiab cov kws tshaj lij raws li koj cov kev xav tau tshwj xeeb.
