E hia ngā momo whakaiti paipa e mōhiotia ana e koe? He aratohu katoa

Ko ngā taputapu whakaiti paipa tētahi o ngā taputapu tino nui o ngā pūnaha paipa o ēnei rā.
E whakamahia whānuitia ana ēnei i roto i ngā ahumahi pēnei i te hinu me te hau, te matū hinu, te whakaputa hiko, te hanga kaipuke, te maimoatanga wai, me te tukatuka kai.

Ahakoa te āhua māmā, he maha ngā momo, ngā āhua, ngā rauemi me ngā paerewa o ngā whakaiti paipa.
Mā te mārama ki ngā rerekētanga i waenga i ēnei whakaitiiti ka āwhina i ngā kaihangarau, ngā kaihoko, me ngā kaiwhakahaere kaupapa ki te whiriwhiri i te taputapu tika mō te haumaru, te mahi, me te whakahaere utu.

I roto i tēnei aratohu katoa, ka whakautua e mātou tētahi pātai noa engari he mea nui:
E hia ngā momo whakaiti paipa kei reira?
Ka whakamāramahia e mātou ā rātou whakarōpūtanga, ā rātou whakamahinga, ā rātou rauemi, ā rātou paerewa hanga, me ngā tohutohu whiriwhiri.

1. He aha te Whakaiti Paipa?

Ko te whakaiti paipa he momo hononga paipa i hangaia hei hono i ngā paipa e rua o ngā diameter rerekē.
Ko tāna mahi matua he whakaiti i te rahi o te paipa kia maeneene, me te pupuri tonu i te rere me te pēhanga pumau i roto i te pūnaha paipa.

Ko ngā taputapu whakaiti paipa e whakamahia whānuitia ana ina:

• Me whakarerekē te rahi o ngā paipa nā te rere o te wai, nā te hoahoa pēhanga rānei.
• He rerekē te rahi o te tomokanga, te putanga rānei o ngā taputapu i te rahi o ngā paipa
• Me arotau te pūnaha, me whakaiti rānei te utu

Ko ngā whakaitiiti he mea hanga i runga i ngā paerewa o te ao pēnei i te ASTM, ASME, EN, DIN, JIS, me GB.

2. Ngā Momo Matua o ngā Whakaiti Paipa mā te Āhua

I runga i te āhua ā-ira, ka wehea ngā whakaheke paipa ki ngā wāhanga matua e rua.

2.1 Whakaiti Paipa Porowhita

Ko te whakawhāiti porowhita he hononga paipa kei reira te rārangi pokapū o ngā paipa tomo me te whakaputa e hangai tonu ana.
He āhua koeko ōrite tōna e whakaiti ana i te whānui mai i tētahi pito ki tētahi pito.

Ngā Āhuatanga Matua:

• Ka noho pūmau te whakaritenga o te rārangi waenga
• Whakawhiti rere maeneene, ōrite hoki
