Te mahi a teTe Whakapūtanga Parahie whakamahia ana hei hono i te puna wai me te tohatoha wai whakahoki me ngā taputapu kohikohi wai o ngā paipa whakamahana rerekē. E ai ki te wai e tomo mai ana, e puta atu ana, ko te manifold me te kaikohi wai, nō reira e kiia ana ko te manifold, ko te manifold rānei i roto i te hangarau, ko te manifold rānei hei whakarāpopototanga. Ko tana mahi: Ko te hurihanga me te taurite e pā ana ki, ko te manifold te nuinga o te wā ka wehea ki te manifold parahi me te manifold kowiri tira, nō reira he pai ake te whiriwhiri i te manifold kowiri tira, ko te parahi rānei? He aha te rerekētanga i waenga i ēnei rauemi e rua?

Ko te rerekētanga i waenga i te ipu parahi me te ipu kowiri tira:

Tuatahi: he rerekē te waikura me te waikura

Kāore te maitai kore waikura e waikura, ā, e kore hoki e waikura. Kāore te maitai kore waikura 304 tūturu e rerekē te tae mō ngā tau maha. Ki te rerekē te tae, ko te tikanga he "rino kore waikura". Ka waikurahia te parahi hei whakaputa i te verdigris. Ka whanake te nuinga o ngā manifold parahi i roto i ētahi marama. I pōuri, ā, kua waikurahia.

Tuarua: he rerekē te rahi o te kounga o te kaiwhakahaere

Ko te diameter matua o te manifold kowiri tira whānui ka eke ki te DN40; ko te diameter matua o te manifold parahi ko te DN25, 32.

Tuatoru: He rerekē te wā whakamana

He roa ake te wā whakamana o te ipu maitai kore waikura 304 tūturu i te parahi. Ahakoa kāore e taea te kī he roa ake te roa o te ora o ngā ipu maitai kore waikura, ko te wā whakamana whānui o ngā ipu parahi kei te mākete he 2-3 tau, ko ngā ipu maitai kore waikura ia e whakamahia ana. Ka eke te wā whakamana ki te 5 tau.

Whā: ngā utu rauemi rerekē

He konganuku kore-ferrous te parahi, he nui ake te utu i te kowiri tira, engari he nui ake te utu tukatuka muri o te kowiri tira. Koinei anō te take he maha ngā kaihanga "ngākau pango" e whakamahi ana i te "rino kowiri tira" hei whakaari i a rātou he "kowiri tira", e whakaaro ana te tangata kāore i te pai te kounga o ngā manifolds kowiri tira, ā, ka kino te ingoa o rātou.

Heoi, i te mākete o nāianei, tae atu ki a Ūropi, he nui ake te utu o ngā manifolds kowiri tira tūturu i ērā o ngā manifolds parahi, ā, he uaua ki te wehewehe i te "rino kowiri tira" me te "kowiri tira". Ko te nuinga o ngā rangatira me ngā kaiwhakarato ratonga e whiriwhiri tonu ana i ngā manifolds parahi. Ngongo.
