Amapayipi ensimbi anama-flange ahlanganisiwe awuhlobo lwamapayipi asetshenziswa ezintweni ezihlukahlukene, okuhlanganisa ukuhlinzekwa kwamanzi, izimiso zokukhucululwa kwendle, namapayipi ezimboni.Lawa mapayipi enziwe nge-iron ductile, okuwuhlobo lwe-cast iron eye yathuthukisa amandla kanye ne-ductility.
I- integrally cast flange iyingxenye yepayipi ephonswa njengesiqephu esisodwa nomzimba wepayipi.Lokhu kusho ukuthi i-flange ayiyona ingxenye ehlukile ehlanganisiwe noma eboshiwe kumbhobho, kodwa kunalokho ingxenye ebalulekile yepayipi ngokwayo.Lo mklamo unikeza izinzuzo eziningana, kuhlanganise:
1. Amandla athuthukisiwe: I-flange ehlanganisiwe ihlinzeka ngoxhumano oluqinile phakathi kwepayipi ne-flange, njengoba zingekho izindawo ezibuthakathaka noma izindlela zokuvuza ezingase zibe khona.
2. Isikhathi sokufaka esincishisiwe: I-flange ehlanganisiwe iqeda isidingo sezingxenye ezihlukene ze-flange, ezingasindisa isikhathi ngesikhathi sokufakwa.
3. Izindleko zokunakekela eziphansi: I-flange ehlanganisiwe inciphisa ubungozi bokuvuza nezinye izinkinga zokunakekela, ezingonga imali empilweni yepayipi.
Amapayipi ensimbi ane-ductile anama-flange ahlanganisiwe atholakala ngobukhulu obuhlukahlukene kanye nezilinganiso zokucindezela, okuwenza afanelekele uhla olubanzi lwezinhlelo zokusebenza.Zibuye zihambisane nezinhlobonhlobo zezinhlelo zokuhlanganisa, kufaka phakathi ama-push-on, ama-mechanical, nama-flanged joints.
Amapayipi e-Ductile iron (DI) anama-flange asakazwa ngaphakathi awuhlobo lwamapayipi oluvame ukusetshenziswa ekuhlinzekeni kwamanzi nasezinhlelweni zokukhucululwa kwendle.Lawa mapayipi enziwe nge-iron ductile, okuwuhlobo lwensimbi oluye lwaphathwa ngenani elincane le-magnesium ukuze ikwazi ukuguquguquka futhi ihlale isikhathi eside kunensimbi evamile.
Ama-flange afakwe ngaphakathi ayisici esibalulekile sala mapayipi, njengoba avumela ukuxhuma kalula kwamanye amapayipi nokufakwa.Ama-flange aphonswa ngqo epayipini ngesikhathi sokukhiqiza, okuqinisekisa ukuxhumana okuqinile nokuvikelekile okumelana nokuvuza nezinye izinhlobo zomonakalo.
Amapayipi e-DI anama-flanges angaphakathi ayaziwa ngamandla awo aphezulu kanye nokuqina, okuwenza alungele ukusetshenziswa ezindaweni ezinzima kanye nezinhlelo zokusebenza lapho amapayipi azobhekana nemithwalo esindayo noma ukucindezela okukhulu.Ziyakwazi futhi ukumelana nokugqwala nezinye izinhlobo zomonakalo, okusiza ekwandiseni isikhathi sazo sokuphila nokunciphisa izindleko zokuzilungisa ngokuhamba kwesikhathi.
Sekukonke, amapayipi e-DI anama-flanges angaphakathi ayisixazululo esinokwethenjelwa futhi esingabizi kakhulu sohlelo olubanzi lokuhlinzekwa kwamanzi nokuthuthwa kwendle.Banikeza inani lezinzuzo ngaphezu kwezinye izinhlobo zamapayipi, okuhlanganisa amandla akhulayo, ukuqina, nokumelana nokulimala nokugqwala.
