Kudzvinyirira Makirasi eFlanges
Forged simbi flanges ASME B16.5 inogadzirwa mumanomwe ekutanga Pressure Classes:
150
300
400
600
900
1500
2500
Pfungwa yeflange ratings inoda zvakajeka. A Class 300 flange inokwanisa kubata kudzvanya kwakawanda kudarika Class 150 flange, nekuti Class 300 flange inovakwa nesimbi yakawanda uye inokwanisa kushingirira zvakanyanya. Nekudaro, pane akati wandei ezvikonzero zvinogona kukanganisa kugona kwekumanikidza kweflange.
Pressure Rating Dhizaini
Iyo Pressure Rating yemaflange ichapihwa muClass.
Kirasi, inoteverwa nenhamba isina dimensionless, ndiyo dhizaini yekumanikidza-tembiricha zviyero sezvinotevera: Kirasi 150 300 400 600 900 1500 2500.
Mazita akasiyana anoshandiswa kuratidza Dhipatimendi Kirasi. Semuenzaniso: 150 Lb, 150 Lbs, 150# kana Kirasi 150, ese anoreva zvakafanana.
Asi pane chiratidzo chimwe chete chakarurama, uye ndiyo Pressure Kirasi, zvinoenderana neASME B16.5 iyo yekumanikidza chiyero inhamba isina dimension.
Muenzaniso wePressure Rating
Flanges inokwanisa kutsungirira matambudziko akasiyana pane tembiricha dzakasiyana. Sezvo tembiricha inowedzera, chiyero chekumanikidza cheflange chinodzikira. Semuyenzaniso, Class 150 flange yakayereswa kusvika ku270 PSIG pamamiriro ekunze, 180 PSIG painoda kusvika 400°F, 150 PSIG pa600°F, uye 75 PSIG pa800°F.
Mune mamwe mazwi, kana dzvinyiriro ichidzika, tembiricha inokwira uye neimwe nzira. Zvimwe zvinhu ndezvekuti flanges inogona kuvakwa kubva kune zvakasiyana zvinhu, senge simbi isina tsvina, cast uye ductile iron, kabhoni simbi nezvimwewo.
Pazasi muenzaniso weflangeNPS 12nemakirasi akawanda ekumanikidza. Sezvaunogona kuona, dhayamita yemukati uye dhayamita yechiso chakasimudzwa zvachose; asi kunze kwedhayamita, bhaudhi denderedzwa uye dhayamita yemabhoti maburi inova yakakura mukirasi yega yega yepamusoro yekumanikidza.
Nhamba uye madhayamita (mm) emaburi emabhoti ndeaya:
Kirasi 150: 12 x 25.4
Kirasi 300: 16 x 28.6
Kirasi 400: 16 x 34.9
Kirasi 600: 20 x 34.9
Kirasi 900: 20 x 38.1
Kirasi 1500: 16 x 54
Kirasi 2500: 12 x 73
Pressure-Temperature Ratings - Muenzaniso
Dzvinyiriro-tembiricha ratings ndiyo yakanyanya kubvumidzwa kushanda gage kumanikidza mumabhawa mayuniti patembiricha mumadhigirii celsius. Kune tembiricha dzepakati, kududzira kwemutsara kunobvumidzwa. Kupindirana pakati pemazita ekirasi hakubvumidzwe.
Kutsikirira-tembiricha ratings inoshanda kune flanged majoini anoenderana nezvinogumira pabholting uye pamagaskets, ayo anogadzirwa maererano nemaitiro akanaka ekurongeka uye kusangana. Kushandiswa kweaya maresheni emajoini akachinjika asingaenderane neaya maganhuriro ibasa remushandisi.
Tembiricha inoratidzwa kuchiyero chepressure inoenderana tembiricha yegoko rine pressure yechikamu. Kazhinji, tembiricha iyi yakangofanana neyemvura irimo. Kushandisa chiyero chekumanikidza chinoenderana netembiricha kunze kweiyo yemvura irimo ibasa remushandisi, zvichienderana nezvinodiwa nemakodhi anoshanda uye mirau. Chero tembiricha iri pasi -29°C, mwero hauzove wakakura kupfuura mwero wakaratidzwa -29°C.
Semuenzaniso, pazasi iwe unowana matafura maviri ane zvinhu zvikwata ASTM, uye mamwe maviri matafura ane flange pressure-tembiricha ratings kune izvo ASTM zvinhu ASME B16.5.
