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.
