Paipa Kowiri tira kore-tuitui MP (Whakakanapa Mīhini)
Whakataki Hua
Ko te whakakanapa e pā ana ki te tikanga miihini e whakamahi ana i ngā mahi ā-ringa, matū, hikohiko rānei hei whakaiti i te taratara o te mata o te paipa maitai kore waikura, kia whiwhi ai i tētahi mata kanapa, papatahi hoki. Ko te whakamahi i ngā taputapu whakakanapa me ngā matūriki whakakoi, i ētahi atu mea whakakanapa rānei hei whakarerekē i te mata o te paipa maitai kore waikura.
E rua ngā wāhanga o te whakakanapa paipa kowiri tira: te whakakanapa mata o roto me te whakakanapa mata o waho. Ko te nuinga o te whakakanapa ngongo kowiri tira he whakakanapa ā-ringa, ki te tika te mahi me nui ake te whakakanapa hiko.
Kāore e whakaaetia kia whakakanapahia ngā paipa whakakanapa ā-ringa mā te whakakanapa ā-ringa hei whakaiti i te taratara o te mata o te pakitara paipa, kia maeneene ai, kia ma ai hoki. Ka taea te whakarato i te taha waho ki te whakaotinga mira, te whakaotinga kanapa, te whakakanapa 180, te whakakanapa 240, te whakakanapa 400, me te whakakanapa angiangi ake i runga i ngā hiahia o te kiritaki.
Ka whakamahia te whakakanapa ā-ringa hei whakarato i te āhua ōrite, kanapa hoki. Mā te huri i ngā ngongo ki ngā kirikiri kirikiri kia pai ake te āhua, kia pai ake te āhua, kia tutuki ai te āhua e hiahiatia ana, te āhua taratara rānei o te mata. Ka taea te whakarato i ngā ngongo i roto i ngā momo āhua mata rerekē, i te Diameter o Waho, o Roto hoki, i runga i ngā hiahia o te kiritaki.
Mō ngā mahi whakapaipai, mō ngā ngongo hauora, ka orohia te taha o waho, o roto hoki kia maeneene ai te āhua, kia kore ai e kohia ngā mea koiora ki runga i ngā ngongo. Ka taea hoki te whakamahi i te oro ā-ringa hei whakarite i ngā ngongo mō te oro hiko kia tutuki ai te āhua mata e hiahiatia ana.
Ngā Painga
– te kanapa teitei
– Whakapai ake i te āhua o te mata, Whakapai ake i te ma o te mata
– Whakaitihia te piri o te hua
Ngā ngoikoretanga
– Kāore e taea te kanapa te pumau, ā, kāore e roa
– Tērā pea ka pāngia e te waikura
– Ka ngoikore te kaha ā-pūkaha o te mata

Paipa Whakakanapahia e te Mīhini
Ko te tikanga, kāore e whakaaetia kia tukatukahia ngā paipa whakakoi miihini mā te whakakoi miihini hei whakaiti i te taratara o te mata o te pakitara paipa, kia maeneene ai, kia ma ai hoki.
Te taratara: Ra ≤ 0.8 μm
Rauemi
TP316L, TP304L
Paerewa
ASTM A312
Te Pākari o te Mata (Ra)
Mata: 0.6μm
Manawanui
E ai ki te ASTM A312
āhuatanga
● Te whakahaere pakari i te whānui o waho me ngā ātete matotoru o te pakitara.
● I muri i te whakamahana kanapa katoa, he pai tōna ātete ki te waikura.
● He pai te āhua o te whakarewa.
● Whai muri i te horoinga me ngā tukanga whakaputa tino pakari, he pai te taratara.
