Flanges chinhu chakakosha mumapombi masisitimu, anoshandiswa kubatanidza mapaipi, mavharuvhu, pombi, nemimwe midziyo. Pakusarudza flanges, mipimo mikuru miviri inofanira kurangarirwa – DN (Dimension Nominal) uye ANSI (American National Standards Institute). Kunyange zvazvo zvose zviri zviviri zvakajairika, pane mimwe misiyano yakakosha yekunzwisisa pakusarudza pakati peDN vs ANSI flanges. Ichi chinyorwa chichafananidza dn vs ansi flanges zvakadzama kuti ikubatsire kuita sarudzo chaiyo.
Nhanganyaya
Flanges inopa nzira yekubatanidza pombi uye kuendesa zvinwiwa kana magasi nekubatanidza pamwe nemagaskets pakati pawo kuvhara kubatana.. Iwo anoshandiswa mune akawanda maapplication kubva kuoiri uye gasi indasitiri kune chikafu uye chinwiwa kugadzirisa, magetsi anomera, nezvimwe.
Kune maviri makuru epasi rose zviyero zveflange zviyero uye zviyero:
- DN – Dimensional Nominal (European / ISO standard)
- ANSI – American National Standards Institute (American standard)
Kunyange zvazvo zvose zviri zviviri zvichitevera nheyo imwechete yekugadzira, kune misiyano yezviyero, pressure ratings, faces, uye mabhaudhi mapatani anoita kuti dzisashanduke. Kunzwisisa dn vs ansi flanges kunovimbisa kuti iwe unosarudza maflange akakodzera kune yako pombi system.
Misiyano Yakakosha Pakati peDN neANSI Flanges
Paunenge uchiongorora dn vs ansi flanges, zvinotevera ndizvo zvinhu zvikuru kuenzanisa:
Dimensions
- DN flanges yakavakirwa pamazita epombi saizi ine yakajairika dhayamita increments.
- ANSI flanges ine mwero inch saizi isina hukama zvakananga nehukuru hwepombi.
Izvi zvinoreva DN 100 flange inowirirana ne 100mm pombi, nepo ANSI 4 ”flange ine bore ye approx. 4.5”. DN flanges inoshandisa metrics nepo ANSI ichishandisa emperial units.
Pressure Ratings
- DN flanges inoshandisa PN rating – iyo yakanyanya kudzvanywa muBAR pane imwe tembiricha.
- ANSI flanges inoshandisa Kirasi chiyero – iyo yakanyanya psi kudzvinyirira kunobva pane simba rezvinhu.
Semuyenzaniso, a DN150 PN16 flange = ANSI 6” 150# flange mukumanikidza kubata kugona.
Kutarisana Zvitaera
- DN flanges anoshandisa Form B1 kana B2 faces.
- ANSI flanges inoshandisa Raised Face (RF) kana Flat Face (FF) faces.
B1 yakafanana neRF, nepo B2 inofananidzwa neFF. Kutarisana kunofanirwa kuenderana nekusimbiswa kwakakodzera.
Bolt Circles
- DN bolt maburi anowanikwa zvichibva pane zita rekuti dhayamita.
- ANSI bolt madenderedzwa anobva pane flange kirasi rating.
Bolt maburi haawirirane pakati pezvitaera zviviri.
Zvishandiso
- DN flanges inoshandisa metric based materials – P250GH, 1.4408, etc.
- ANSI inoshandisa imerial/US mamakisi – A105, A182 F316L, etc.
Zvinhu zvinofanirwa kuenzana nekubata tembiricha inodiwa uye kumanikidza.
Sezvauri kuona, dn vs ansi flanges vane misiyano yakati wandei inoita kuti isashanduke. Kusanganisa maviri acho kunowanzo tungamira mukudonha, kukuvara, nedzimwe nyaya.

DN vs ANSI Flange FAQ
Mimwe mibvunzo inowanzoitika nezve dn vs ansi flanges inosanganisira:
DN uye ANSI flanges zvinochinjika?
Aihwa, DN uye ANSI flanges haigoni kuchinjana zvakananga nekuda kwekusiyana kwezviyero, ratings, faces, uye zvinhu. Kuedza kuroora DN flange kune ANSI flange kunozokonzera kusarongeka.
Unogona here kushandisa DN flange pane ANSI pombi?
Aihwa, zviyero zvakasiyana zvinoreva kuti DN flange haifanire kuenderana neANSI pombi saizi. Iwo akagadzirwa semasisitimu kuti aenderane neDN flanges neDN pombi, uye ANSI ine ANSI.
Unoshandura sei DN kuita ANSI flange size?
Iko hakuna kutendeuka kwakananga pakati peDN vs ANSI pombi saizi. Chati iri pamusoro inopa fungidziro yakaenzana kune yakajairwa DN uye ANSI nemazita eflange saizi. Nguva dzose tarisa zviyero chaizvo – zviyero zvinogona kusiyana zvichienderana nezviyero.
Ndinofanira kushandisa DN kana ANSI flanges?
Kana yako pombi system iri munzvimbo uchishandisa ISO zviyero (Europe, Middle East, Asia), DN flanges ingangodiwa. KuNorth America kushandisa ANSI zviyero, ANSI flanges ichave yakajairika sarudzo. Shandisa chiyero chinoenderana nepiping yako yese kuti ikwane uye kushanda kwayo.
Unogona here bhaudhi DN uye ANSI flanges pamwechete?
Haufanire kubatanidza pamwe chete isingaenzaniswi DN vs ANSI flanges. Iwo akasiyana mabhaudhi madenderedzwa haawirirane, zvichiita kuti gaskets dzigare zvisina kufanira, kudonha, uye zvinogona kukanganisa pasi pekumanikidzwa.
Mhedziso
Kana zvasvika pakusarudza flanges, kunzwisisa misiyano yakakosha pakati peDN vs ANSI zviyero kwakakosha. Mismatch flanges inogona kutungamirira mukudonha, kukuvara kwemidziyo, uye kugadzirisa kunodhura. Nokuenzanisa zviyero, pressure ratings, faces, uye zvinhu, unogona kuve nechokwadi kuti unosarudza inowirirana DN kana ANSI flanges nguva dzese.
Nezvivakwa pasi rose, Jmet Corp inopa ese DN uye ANSI flanges kusangana nezvinodiwa munharaunda. Bata nesu nhasi kuti tikurukure nezvechishandiso chako uye uwane rubatsiro pakusarudza akakodzera flanges. Nyanzvi dzedu dzinogona kukufambisa iwe kuburikidza nedn vs ansi flanges zviyero uye kupa yakavimbika kutumira pane chaizvo zvaunoda.
