API Pipe Flanges

API Pipe Flanges

A flange denderedzwa rakakwenenzverwa, muromo kana rimu, ingave yekunze kana yemukati, iyo inoshandira kuwedzera simba (seye flange yedanda resimbi senge I-danda kana T-danda); yekusungirirwa nyore / kuendesa kwesimba rekubata nechimwe chinhu (seye flange kumagumo kwepombi, humburumbira hwemhepo, nezvimwewo, kana pane iyo lens yegomo rekamera); kana kudzikamisa uye kutungamira mafambiro emuchina kana zvikamu zvaro (kunge yemukati flange yetiraki mota kana tramu vhiri, inoita kuti mavhiri asamhanye kubva kunjanji). Izwi rekuti "flange" rinoshandiswawo kune rudzi rwechishandiso chinoshandiswa kugadzira mafrange.

ASME zviyero (US)

Pipe flanges inoitwa kune zviyero zvinodaidzwa neASME B16.5 kana ASME B16.47, uye MSS SP-44. Izvo zvinowanzo gadzirwa kubva kuzvinhu zvakagadzirwa uye zvine machined nzvimbo. ASME B16.5 inoreva mazita ekukura kwepombi (NPS) kubva ½ ”kusvika 24 ″. B16.47 inovhara NPSs kubva pa26 kusvika pa60 ″. Chirevo chega chega chinowedzeredza maflege mumakosi ekumanikidza: 150, 300, 400, 600, 900, 1500 uye 2500 yeB16.5, uye B16.47 inojekesa mafrange ayo kuita makosi ekumanikidza 75, 150, 300, 400, 600, 900. Zvisinei makirasi aya haaenderane nekumanikidza kwakanyanya mu psi. Panzvimbo iyoyo, kumanikidza kwakanyanya kunoenderana nezvinhu zveiyo flange uye tembiricha. Semuenzaniso, kumanikidza kwakanyanya kweClass 150 flange ndeye 285 psi, uye yeClass 300 Flange iri 740 psi (ese ari eASMM A105 Carbon Steel uye tembiricha pazasi pe100F).

Iyo gasket mhando uye bhaudhi mhando zvinowanzo domwa neyakajairwa (s); zvisinei, dzimwe nguva zviyero zvinonongedzera kuASME Boiler uye Pressure Vessel Code (B & PVC) kuti uwane ruzivo (ona ASME Code Chikamu VIII Chikamu 1 - Appendikisi 2). Aya ma flange anozivikanwa neASME Pipe Codes senge ASME B31.1 Power Piping, uye ASME B31.3 Maitiro Ekurapa.

Zvishandiso zvemaflanges zvinowanzo kuve pasi peASME kudomwa: SA-105 (Rondedzero yeCarbon Simbi Forgings yePiping Zvishandiso), SA-266 (Rondedzero yeCarbon Simbi Forgings Yekumanikidza Midziyo Yezvinhu), kana SA-182 (Rondedzero yeFoged kana yakatenderedzwa Alloy- Simbi Pipe Flanges, Ndokugadzira Fittings, uye maValvu uye Zvikamu zveHigh-Temperature Service). Uye zvakare, kune akawanda "indasitiri akajairwa" mafiranges ayo mune mamwe mamiriro anogona kushandiswa pane ASME basa.

Chigadzirwa chigadzirwa chinosanganisira SORF, SOFF, BLRF, BLFF, WNRF (XS, XXS, STD & Chirongwa 20, 40, 80), WNFF (XS, XXS, STD & Chirongwa 20, 40, 80), SWRF (XS & STD) , SWFF (XS & STD), Yakagadziriswa RF, Yakasungirirwa FF & LJ, ine hukuru kubva pa 1/2 ″ kusvika 16 ″. Iyo bolting yekushandisa inoshandiswa kune flange yekubatanidza ndeye stud bolts mated nemaviri nati (washer pazvinodiwa). MuPetrochemical maindasitiri, ASTM A193 B7 STUD & ASTM A193 B16 Stud Bolts anoshandiswa sezvo aya aine simba rakasimba.
