NSW F304 Flange Takiwa kuwaha, he mea hanga ki te rauemi ASTM A182 F304, ko te whakatuwheratanga me te kati o te wahanga o te keti kuaha maitai o te potae tutaki ko te keeti. Ko te ahunga nekehanga o te kuaha e tika ana ki te ahunga o te wai. Ka taea anake te whakatuwhera me te kati i te puera kuaha maitai, kaore e taea te whakatika me te tarai. E rua nga papa hiri o te kuaha o te keeti kuaha maitai. Ko nga mata hiri e rua o te aratau aratau waro kuaha he ahua poro, a he rereke te koki poro ki nga tawhā takirere. Ko nga momo taraiwa o nga maataki kuaha maitai he: a-ringa, pneumatic, hiko, hononga hau-wai.
Ko te mata hiri o te hiri o te keeti kuaha maitai ka taea te hiri anake e te pehanga reo, ara, ka whakamahia te pehanga reo ki te pehi i te mata hiri o te kuaha ki te nohoanga takirere i tera taha ki te whakarite i te mata hiri, ko hiri-whaiaro. Ko te nuinga o nga paera o te kuaha ka pehia ki te hiri, ara, ka kati te paera, he mea tika ki te akiaki i te pereti o te kuaha ki te nohoanga valve ma te kaha o waho ki te whakarite i te hiri o te mata hiri.
Ko te keti o te keti keeti e neke ana i te taha o te kakau takirere, e kiia nei ko te maarere o te keeti toka (e kiia ana ko te maataki keeti tuwhera). Ko te tikanga he miro trapezoidal kei runga i te rakau hiki. Ka neke te nati mai i te tihi o te takirere me te riu arataki i runga i te tinana takirere ki te huri i te nekehanga hurihuri ki te nekehanga raina, ara, te taipana whakahaere ki roto i te pana whakahaere.
Nga painga o te maataki kuaha maitai
1. He iti te parenga wai.
2. He iti te kaha o waho e hiahiatia ana mo te whakatuwhera me te kati.
3. Ko te aronga rere o te reo karekau e herea.
4. I te wa e tuwhera ana, he iti ake te paheketanga o te mata hiri na te reo mahi i tera o te paera o te ao.
5. He ngawari noa te ahua, he pai te mahi whakarewa.
Nga Taonga Panui Panui
Ka taea te tuku i te tinana takirere NSW me nga taonga kuti i roto i te momo Forged me te momo Maka. I te taha o nga taonga kowiri me te waro waro, ka hangaia e matou nga reera i roto i nga taonga motuhake penei i te titanium, te nickel alloys, HASTELLOY®*, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys me nga rauemi reanga Urea.
