Whakatupato mokowiri tira kowiri tirae whai ake nei: rokiroki wā roa o flanges kowiri tira, kia tirohia i runga i te wātaka, maha ki te mata tukatuka kitea me pupuri ma, poke ma, neatly rongoa i roto i te maroke me te hā wahi roto, kua tino rāhuitia ki te puranga tuwhera rokiroki ranei.Kowiri tira flangedpaoro pōro, globe valve, kuwaha vaolo ka whakamahia, anake mo te tino tuwhera katia ranei, kaua e tukua ki te mahi i te rere ture, kia rite ki te karo i taatiraa horo mata, kākahu whakatere. Ko te keti keti me te hiko o te ao i roto i te taputapu hiri kua huri, ko te wira o te ringa ki runga o te mata o te upoko mo te wa roa e kore e waikura, e kore e waikura.

Kowiri tira flangeKo te werohanga he tikanga nui mo te hanga kirihou, kua whakamahia nuitia ki te hanga. Kei a ia nga ahuatanga e whai ake nei:
1. he poto te hurihanga hangai, ka taea te ahua uaua, te rahi tika, me nga waahanga kirihou whakarewa, kore-whakarewa ranei.
2. He kaha te urutau ki te hanga momo kirihou. I tenei wa, tata ki te katoa o nga thermoplastics haunga nga fluoroplastics ka taea te hanga penei, a ka taea hoki etahi kirihou thermosetting te hanga ma te werohia.
3. te kaha o te whakaputa, ngawari ki te mohio ki te whakaputa aunoa.
4. He nui te utu o nga taputapu miihini werohanga, he uaua te hanganga mokowhiti, he nui te utu o te hangahanga, na reira he pai rawa te hangai mo te hanga papatipu.
