DIN 3202 F4, DIN 3202 F5 me BS5163 Takirere Kēti Nohoanga Manawanui: Ngā Rerekētanga Matua me te Aratohu Kōwhiri

E whakamahia whānuitia ana ngā takirere kēti kakau pakari e noho ana, kāore e ara ake ana, i roto i te tohatoha wai inu ā-tāone, i ngā whatunga parakaingaki me ngā kaupapa whakahoutanga wai puta noa i Ūropi, i te Waenganui Rawhiti, i te Tonga-mā-rāwhiti o Āhia me ngā whenua o te Commonwealth. DIN 3202 F4 takirere keti, DIN 3202 F5 takirere keti me BS5163 takirere kuaha e tohu ana i ngā paerewa matua e toru o te ao mō ngā takirere kuaha hiri ngohengohe. He maha ngā kaihoko kaupapa e pāngia ana e ngā hapa tāutanga utu nui nā te mea he whakapoauau te roa kanohi ki te kanohi, ngā rahinga o te takirere me te whānuitanga o te tono o ēnei paerewa e toru. Mā te mārama ki ō rātou rerekētanga matua ka āwhina i te karo i ngā hapa hoko me te huihuinga i te papaanga.

I ahu mai a DIN 3202‑F4 me DIN 3202‑F5 i te paerewa Tiamana DIN 3202, kua whakatauritea inaianei i raro i te paerewa Pākehā EN 558‑1, e rua ngā mea e mau ana i ngā flange DIN‑EN1092‑2 PN10/PN16. Ko te rerekētanga matua i waenga i a F4 me F5 kei roto i te roa o te hanganga kanohi ki te kanohi. He hoahoa poto te DIN F4, he kiato te rahi katoa, he pai mō ngā kaupapa whakakapinga paipa tawhito ina he iti te wāhi tāutanga. He momo tauira roa te DIN F5 me te tinana takirere matotoru ake me te kōhao ā-roto nui ake, e whakarato ana i te pakari me te pumau pai ake mō ngā paipa wai hou me te piki me te heke o te pēhanga. Ko ngā takirere F4 me F5 e whakamahi ana i te tinana rino GGG50 ngawari me te poro rapa EPDM mō te ratonga wai ma i raro i te 80℃.

Ko te BS5163 te paerewa ā-motu o Peretānia i hangaia mō ngā takirere keti o ngā mahi wai, he mea rongonui i ngā kaupapa o te UK, Āwherika me te Middle East Commonwealth. He whānui motuhake tōna, he kanohi ki te kanohi, kāore e rite ki te DIN F4, ki te F5 rānei. E whai ana tōna flange i te paerewa BS4504; kāore e taea te whakawhiti tika i te porowhita pūtu me te rahi o te kōhao ki ngā flange DIN-EN1092-2. Ahakoa he ōrite te rahi DN me te whakatauranga pēhanga PN10/PN16, kāore e taea te whakairi i ngā takirere DIN F4/F5 ki ngā mokowā paipa BS5163 o nāianei, me te ritenga kē. Mō te whakahou i ngā whatunga wai tawhito o te paerewa o Peretānia, me tohu ngā takirere keti e tutuki ana i te BS5163.

Kei te ripanga e whai ake nei ngā whakarāpopototanga o ngā tawhā matua hei tirotiro tere:

I te wā e whiriwhiri ana i te mutunga, me whakaū ngā mea matua e toru: te roa o te paipa o nāianei, te rahi o te pūtu o te flange, me ngā whakaritenga paerewa ā-rohe o te kaupapa. Kaua rawa e whakaaro he mea whakawhitiwhiti te F4, te F5 me te BS5163 nā te mea he takirere kēti pakari katoa ēnei. Mō ngā kaupapa o te tuawhenua o Ūropi, ko te F4 mō te whakakapinga me te F5 mō te hanganga hou te mea pai ake. Mō ngā kaupapa e whai ana i ngā whakaritenga o Peretānia, me piri tonu ki te paerewa BS5163 hei whakakore i te mōrearea o te mahi anō.
