Ka whakawhirinaki mātou ki te whakaaro rautaki, ki te whakahou tonu i ngā wāhanga katoa, ki ngā whanaketanga hangarau, ā, ki ā mātou kaimahi hoki e whai wāhi tika ana ki tō mātou angitu mōtuke ppr 90Ko te pai o te kiritaki tā mātou whāinga tuatahi. Ko tā mātou kaupapa matua he whai i te kounga teitei, me te ahu whakamua tonu. E mihi ana mātou ki a koe kia mahi tahi tātou i te ahunga whakamua, kia hanga tahi ai he heke mai whai rawa.

Ngā paipa PPR

Ki te whakaritea ki ngā paipa whakarewa, he pai ake ngā painga o ngā paipa PPR, arā, he māmā ake te tāutanga, he pai ake te whakamahana, ā, he ātete ki te waikura. He rauemi wai hauora, he pai hoki mō te taiao, ā, koinei hoki te hua wai matua kei te mākete. Ko ngā tae e wātea ana mō ngā paipa PPR ko te mā, te hina, te kakariki me te kari, ko te take o tēnei rerekētanga ko ngā tae rerekē kua tāpirihia.

Haunga ngā āhuatanga o ngā paipa kirihou whānui pērā i te mama, te ātete ki te waikura, te kore e memeha, me te roa o te ora mahi, kei ngā paipa PP-R anō hoki ēnei āhuatanga matua:

1 Kāore he paitini, ā, he akuaku hoki.
Ko ngā rauemi mata o te PP-R he waro me te hauwai anake, ā, kāore he mea kino, he mea paitini rānei. He akuaku, he pono hoki. Ehara i te mea ka whakamahia anake mō ngā paipa wai matao me te wai wera, engari mō ngā pūnaha wai inu parakore anō hoki.

2 Te tiaki wera me te penapena pūngao.
Ko te kawe wera o te paipa PP-R he 0.21w/mk, he 1/200 noa iho tēnei o te paipa maitai.

3 He ātete wera pai ake.
Ko te pūwāhi whakangawari Vicat o te paipa PP-R he 131.5℃. Ka taea e te pāmahana mahi mōrahi te eke ki te 95℃, ka taea te whakatutuki i ngā whakaritenga o te pūnaha wai wera i roto i te ture tuku wai me te rerenga wai o te whare.

4. Roa te ora ratonga.
I raro i ngā āhuatanga o te pāmahana mahi o te 70℃ me te pēhanga mahi (PN) o te 1.0MPa, ka taea e te roanga mahi o te paipa PP-R te neke atu i te 50 tau (mehemea me hanga te rauemi paipa ki te raupapa S3.2 me te S2.5, neke atu rānei); i raro i te pāmahana noa (20℃) ka taea e te roanga mahi te neke atu i te 100 tau.

5 He ngāwari te tāutanga me te hononga pono.
He pai te mahi whakarewa o te PP-R. Ka taea te hono i ngā paipa me ngā hononga mā te whakarewa wera me te whakakotahitanga hiko. He watea te tāutanga, ā, he pono ngā hononga. He nui ake te kaha o te hononga i te kaha o te paipa tonu.

6 Ka taea te hangarua i ngā rauemi.
Ka horoia, ka pakaruhia, ka hangaruatia ngā para PP-R hei whakamahi mā te hanga paipa me ngā taputapu. Kāore te nui o ngā rauemi hangarua e neke ake i te 10% o te tapeke, ā, kāore hoki e pā ki te kounga o te hua.

tāutanga

Ka whakawhirinaki mātou ki te whakaaro rautaki, te whakahou tonu i ngā wāhanga katoa, ngā whanaketanga hangarau, me ā mātou kaimahi e whai wāhi tika ana ki tō mātou angitu mō ngā PPR Pipe Fittings 90 Degree Elbow, Ka oati mātou ki te kounga teitei, ki te kore ngā kiritaki e makona ki te kounga o ngā hua, ka taea e koe te whakahoki mai i roto i ngā rā e whitu me ō rātou āhua taketake.
He utu whakaheke mō te whakaurunga me te hononga PPR Haina, ko te pai o te kiritaki te whāinga tuatahi. Ko tā mātou kaupapa matua he whai i te kounga teitei, me te ahu whakamua tonu. E mihi ana mātou ki a koe kia anga whakamua tahi tātou, kia hanga tahi ai he heke mai angitu.
