I-DIN 2503 kunye ne-DIN 2501 yomibini imigangatho ebekwe yi-Deutsches Institut für Normung (DIN), i-German Institute for Standardization, echaza imilinganiselo ye-flange kunye nezixhobo zokufakelwa kwemibhobho kunye nokudibanisa.
Nantsi eyona mahluko uphambili phakathi kweDIN 2503 kunye neDIN 2501:
Injongo:
- I-DIN 2501: Lo mgangatho uchaza imilinganiselo kunye nezixhobo zeeflange ezisetyenziswa kwimibhobho, iivalvu, kunye nokufakelwa koxinzelelo oluncinci ukusuka kwi-PN 6 ukuya kwi-PN 100.
- I-DIN 2503: Lo mgangatho uquka imiba efanayo kodwa ugxile ngokukodwa kwiiflange zokudityaniswa kwe-weld neck.
Iintlobo zeFlange:
- I-DIN 2501: Igubungela iintlobo ezahlukeneyo zeeflange ezibandakanyai-slip-on flanges, iiflange ezingaboniyo, weld intamo flanges, kwayeiiflange zeplate.
- I-DIN 2503: Ngokukodwa igxininise kwi-weld neck flanges, eyenzelwe izicelo eziphezulu zoxinzelelo kunye neemeko zenkonzo ebalulekileyo apho kukho iimeko ezinzima zokulayisha.
Uhlobo loQhagamshelwano:
- I-DIN 2501: Ixhasa iintlobo ezahlukeneyo zoqhagamshelo kubandakanya ukutyibilika, intamo ye-weld, kunye neeflange ezingaboniyo.
- I-DIN 2503: Yenzelwe ngokukodwa ukudityaniswa kwentamo ye-weld, enika uxhulumaniso oluqinileyo kunye noluqinileyo olufanelekileyo kuxinzelelo oluphezulu kunye nobushushu obuphezulu.
Amanqaku oxinzelelo:
- I-DIN 2501: Iquka uluhlu olubanzi lwemilinganiselo yoxinzelelo ukusuka kwi-PN 6 ukuya kwi-PN 100, efanelekileyo kwiimfuno ezahlukeneyo zoxinzelelo kwiinkqubo zombhobho.
- I-DIN 2503: Ngelixa i-DIN 2503 ingachazi ngokucacileyo imilinganiselo yoxinzelelo, i-weld neck flanges ihlala isetyenziswa kwizicelo zoxinzelelo oluphezulu apho ukulinganiswa koxinzelelo kunokwahluka ngokusekelwe kwizinto eziphathekayo kunye neenkcukacha zoyilo.
Uyilo:
- I-DIN 2501: Ibonelela ngeenkcukacha zoyilo olwahlukeneyo lweeflange ezibandakanya ubuso obuphakanyisiweyo, ubuso obuthe tyaba, kunye nohlobo lweringi yeeflange ezidibeneyo.
- I-DIN 2503: Ijolisa kwi-weld neck flanges ene-hub ende ene-tapered, iququzelela ukuhamba okugudileyo ukusuka kumbhobho ukuya kwi-flange kunye nokubonelela ngentembeko yesakhiwo esigqwesileyo.
Usetyenziso:
- I-DIN 2501: Ifanelekile kuluhlu olubanzi lwezicelo kumashishini afana neoli kunye negesi, ukusetyenzwa kweekhemikhali, ukucocwa kwamanzi, kunye nabanye apho kusetyenziswa iinkqubo zemibhobho.
- I-DIN 2503: Ikhethwa kwizicelo ezibalulekileyo apho uxinzelelo oluphezulu kunye neemeko zobushushu obuphezulu zidibana nazo, njengakwiindawo zokucokisa, iiplanti zepetrochemical, izixhobo zokuvelisa umbane, kunye nofakelo lwaselwandle.
Ngokubanzi, ngelixa zombini imigangatho ijongana nayoiiflangeukufakwa kwemibhobho, i-DIN 2501 ibanzi ngokubanzi kububanzi bayo, igubungela iintlobo ezahlukeneyo zeeflange kunye noqhagamshelo, kanti i-DIN 2503 ilungiselelwe ngokukodwa i-weld neck flanges, ehlala isetyenziswa kwi-high-pressure kunye nezicelo zenkonzo ebalulekileyo.
