Me whai wāhanga ngā pūnaha wai kia roa, kia whai hua hoki te mahi. He mea nui te tūhono parahi PPR ki konei. Ko tōna ātete ki te waikura me te pumau o te wera ka āwhina i te pupuri i te pono o te pūnaha. Ko tePūwero whakauru parahi PPR tae māKa whakarite hoki i te tuku wai e pai ana mō te taiao nā te mea kāore he paitini, he taea hoki te hangarua, he mea mohio hoki mō ngā mahi paipa tauwhiro.
Ngā Whakaaro Matua
- He kaha te pūwero parahi PPR, ā, he ātete ki te waikura. He pai te mahi mō ngā paipa wai e roa ana te mau.
- He haumaru tēnei putanga hiko mō te taiao. Kāore he paitini, ā, ka taea te hangarua, he āwhina nui tēnei ki ngā pūnaha wai ma.
- Ka āraihia e tōna hoahoa ngā turuturu, ka penapena wai, ka whakaiti hoki i ngā utu whakatika. Ka āwhina tēnei ki te penapena moni me ngā rauemi.
Te Mārama ki te Pūnaha Whakauru Parahi PPR
Whakamāramatanga me te Hanganga
TePūwero whakauru parahi PPRHe wāhanga nui te parahi i roto i ngā pūnaha paipa. Ka whakakotahi i te Polypropylene Random Copolymer (PP-R) me ngā whakaurunga parahi hei hanga i tētahi hononga pakari me te pono. Kua hangaia tēnei putanga kia tu atu ki tētahi whānuitanga pāmahana whānui, mai i te –40°C ki te +100°C, kia whai hua ai i roto i ngā āhuatanga rerekē. Kei roto i te parahi e whakamahia ana i roto i ēnei putanga ngā momo kounga teitei pērā i te CuZn39Pb3 me te CW602N, e mōhiotia ana mō tō rātou ātete ki te waikura me te pumau o te wera. Anei tētahi tirohanga tere ki ngā whakatakotoranga hangarau:
| Rauemi | CuZn39Pb3, CW602N, CZ122, C37710, CW614N, CW617N, CW511L, PARAHI DZR |
|---|---|
| Te Maimoatanga Mata | Tae Parahi, Whakakikoruatia ki te Nikara, Whakakikoruatia ki te Chrome |
| Ahu | 1/2”, 3/4”, 1”, 1 1/4”, 1 1/2”, 2”, 2 1/2”, 3”, 4” |
| Paerewa Miro | BSPT/NPT |
Te Tūranga i roto i ngā Pūnaha Paipa Hou
I roto i ngā pūnaha paipa o ēnei rā, he mahi nui tā te pūwero parahi whakauru PPR. He hononga ārai turuturu tōna, kia mau tonu ai te haumaru me te whai hua o ngā pūnaha wai. Mā te miro whakauru ka tika te whakaritenga, ka whakarei ake i te kaha kawe kawenga, ā, ka pai ake i ngā miro PPR taketake. Ehara i te mea ko te roa anake te mahi a tēnei pūwero; engari ka whai wāhi anō hoki ki te pumau. He mea hanga mai i ngā rauemi e pai ana ki te taiao, ā, ka tautoko i ngā mahi hangarua, ka whakaiti i te pānga ki te taiao. Mā te kaha o te pūwero ki te whakahaere i ngā tono wai wera me te wai matao ka taea te whakamahi mō te whakamahi kāinga me te arumoni. Mā tōna hoahoa pakari, ka roa te mahi, ka whakaiti i te hiahia mō ngā whakatikatika me ngā whakakapinga auau.
