I-DIN 2503 kanye ne-DIN 2501 womabili amazinga abekwe yi-Deutsches Institut für Normung (DIN), i-German Institute for Standardization, ecacisa ubukhulu be-flange nezinto zokufakwa kwamapayipi nokuxhumana.
Nawu umehluko oyinhloko phakathi kwe-DIN 2503 ne-DIN 2501:
Inhloso:
- I-DIN 2501: Leli zinga licacisa ubukhulu nezinto ezisetshenziswayo zamapayipi, amavalvu, nokufakwa kwezingcindezi ezisuka ku-PN 6 kuye ku-PN 100.
- I-DIN 2503: Leli zinga lihlanganisa izici ezifanayo kodwa ligxile ikakhulukazi kuma-flange okuxhumana kwentamo ye-weld.
Izinhlobo ze-Flange:
- I-DIN 2501: Imboza izinhlobo ezahlukahlukene zama-flange kufaka phakathiama-slip-on flanges, izimpumputhe flange, weld neck flanges, futhiamapuleti flange.
- I-DIN 2503: Ngokuyinhloko igxile kuma-weld neck flanges, ehlelelwe izinhlelo zokusebenza ezinomfutho ophezulu kanye nezimo zesevisi ezibucayi lapho kunezimo ezinzima zokulayisha.
Uhlobo Lokuxhumana:
- I-DIN 2501: Isekela izinhlobo ezahlukene zokuxhuma okuhlanganisa ukushelela, intamo yokushisela, nama-blind flange.
- I-DIN 2503: Idizayinelwe ngokuqondile ukuxhumana kwe-weld neck, ehlinzeka ngoxhumano oluqinile noluqinile olufanele izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu.
Izilinganiso Zokucindezela:
- I-DIN 2501: Ihlanganisa ububanzi obubanzi bezilinganiso zokucindezela ukusuka ku-PN 6 kuya ku-PN 100, ezifanele izidingo ezihlukene zengcindezi kumasistimu amapayipi.
- I-DIN 2503: Nakuba i-DIN 2503 ingachazi ngokucacile izilinganiso zokucindezela, ama-weld neck flange avame ukusetshenziswa ezinhlelweni zokucindezela okukhulu lapho izilinganiso zengcindezi zingahluka ngokusekelwe kokubalulekile kanye nokucaciswa kwedizayini.
Idizayini:
- I-DIN 2501: Ihlinzeka ngezicaciso zemiklamo ehlukahlukene yama-flange kufaka phakathi ubuso obuphakanyisiwe, ubuso obuyisicaba, nama-flange ohlobo lwendandatho.
- I-DIN 2503: Igxile kumaflange entamo yokushisela anehabhu ende ecijile, ehambisa ukugeleza okushelelayo ukusuka epayipini ukuya ku-flange nokuhlinzeka ngobuqotho besakhiwo esihle kakhulu.
Izicelo:
- I-DIN 2501: Ifanele uhla olubanzi lwezicelo ezimbonini ezifana nowoyela negesi, ukucubungula amakhemikhali, ukuhlanzwa kwamanzi, nokunye lapho kusetshenziswa khona amapayipi amapayipi.
- I-DIN 2503: Ikhethelwa izinhlelo zokusebenza ezibucayi lapho kuhlangatshezwana khona nezimo zomfutho ophezulu kanye nezinga lokushisa eliphezulu, njengasezindaweni zokuhluza, izimboni ze-petrochemical, izindawo zokuphehla ugesi, kanye nokufakwa ogwini.
Sekukonke, kuyilapho zombili izindinganiso zisebenzaama-flangeekufakweni kwamapayipi, i-DIN 2501 ijwayeleke kakhulu kububanzi bayo, ihlanganisa izinhlobo ezahlukene zama-flange nokuxhumana, kuyilapho i-DIN 2503 iklanyelwe ngokukhethekile ama-weld neck flange, evame ukusetshenziswa ekucindezelekeni okuphezulu nasezinsizeni ezibucayi.
