FRP Flange
Whakaahuatanga Hua
Ko ngā flange FRP (Freberglass Reinforced Plastic) he hononga porowhita e whakamahia ana hei hono i ngā paipa, i ngā takirere, i ngā papu, i ētahi atu taputapu rānei hei hanga i tētahi pūnaha paipa katoa. He mea hanga ēnei mai i tētahi rauemi hiato kei roto ko ngā muka karāhe hei rauemi whakakaha me te kapia hangai hei pūtake. Ka hangaia ēnei mā te whakamahi i ngā tukanga pēnei i te whakahāngai, te whakatakoto ā-ringa, te takai miro rānei.
Ngā Āhuatanga o te Hua
Nā te hanganga ahurei o ēnei flange FRP, he nui ngā painga o ēnei flange whakarewa tuku iho:
- Ātete Pai ki te Waikura: Ko te āhuatanga tino kitea o ngā flanges FRP ko tō rātou kaha ki te ātete i te waikura mai i ngā momo matū rerekē, tae atu ki ngā waikawa, ngā kawakore, ngā tote, me ngā whakarewa waro. Nā tēnei ka whakamahia whānuitia i roto i ngā taiao e kawehia ana ngā wai waikura, pērā i roto i ngā ahumahi matū, hinu, whakarewa, hiko, rongoā, me te kai.
- Māmā, Kaha Rawa: Ko te matotoru o te FRP he 1/4 ki te 1/5 noa iho i te matotoru o te maitai, engari he rite tonu tōna kaha. Mā tēnei ka māmā ake te kawe me te tāuta, ā, ka whakaitihia te kawenga katoa ki runga i te pūnaha paipa.
- Ārai Hiko Pai: He rauemi kore-arahi hiko te FRP, ā, he pai rawa ngā āhuatanga ārai hiko mō ngā flange FRP. He mea nui tēnei i roto i ngā taiao motuhake hei ārai i te waikura hikohiko.
- Ngāwari te Hoahoa: Mā te whakarerekē i te tauira kapia me te whakaritenga o ngā muka karāhe, ka taea te hanga ritenga i ngā flange FRP kia tutuki ai ngā whakaritenga motuhake mō te pāmahana, te pēhanga, me te ātete ki te waikura.
- He iti te utu tiaki: Kāore ngā flange FRP e waikura, e memeha rānei, ā, ka roa te ora o te mahi, ka tino whakaiti i ngā utu tiaki me te whakakapinga.
Momo Hua
I runga i te tukanga hanga me te āhua hanganga, ka taea te whakarōpū i ngā flanges FRP ki ētahi momo:
- Kotahi-Wāhanga (Whakauru): Ka hangaia tēnei momo hei wāhanga kotahi me te tinana paipa, e whakarato ana i tētahi hanganga piripono e tika ana mō ngā tono pēhanga iti ki te waenga.
- Flange Wetekina (Flange Hononga Whāriki): He mowhiti flange wetekina, hurihuri noa, me te pito porotaka pumau i runga i te paipa. Mā tēnei hoahoa ka māmā ake te tāutanga, inā koa i roto i ngā hononga maha-ira.
- Flange Matapo (Flange Kore/Taupoki Mutunga): Hei hiri i te pito o te paipa, hei tirotiro i te pūnaha paipa, hei pupuri rānei i tētahi atanga.
- Pūwero Hononga: Ka whakaurua te paipa ki roto i te kōhao o roto o te pūwero, ka honoa marietia mā roto i ngā tukanga here piri, takai rānei, kia pai ai te mahi hiri.
