He Kupu Whakataki ki ngā Pūnaha Hononga Paipa DI

Electrosteel D]. Kei te wātea ngā paipa me ngā hononga me ngā momo pūnaha honohono e whai ake nei:

– Ngā Hononga Pana Ngāwari o te Kōpuku me te Spigot
– Ngā Hononga Ārai Momo Pana-ake
– Ngā Hononga Ngāwari Ā-Mīhini (ngā hononga anake)
– Hononga Flanged

Ngā Hononga Pana-ā-ngāwari o te Pūnaha me te Spigot

Ko ngā hononga ngāwari o te pūwero me te pūwero he mea hanga ki ngā gasket rapa hangai (EPDM/SBR) he āhua motuhake. He 'Rekereke' mārō, he 'Pūru' ngāwari hoki tō te gasket. I roto i te hononga pana-ake, ka pēhia te pūru ngohengohe o te gasket rapa ina whakaurua te pūru ki roto i te pūwero. Ka maukati te 'Rekereke' i te tūranga o te gasket, ā, kāore e tukua te gasket kia nekehia ina panaia te pūru ki roto. Ka piri ake te hononga i te pikinga o te pēhanga o roto o te wai. Ka herea te rapa ki tētahi wāhi, ā, kāore e taea te pupuhi ki waho.

Te piko e whakaaetia ana i ngā hononga o te Socket me te Spigot

Mēnā e tika ana kia whakapikohia te paipa mai i tētahi rārangi tika, i te papa poutū, i te papa whakapae rānei, hei karo i ngā arai, kaua te whakapiko i te hononga e neke ake i te mea e whai ake nei:

Kua whakamātauhia ngā momo o ngā paipa rino hiko-maitai

Mā te hoahoa a Electrosteel o te pūwero me te gasket rapa ka āta tiakina te hononga mā te Whakamātautau Momo e ai ki te BSEN:545 me te ISO:2531. Whakamātautau Momokei te whakamātautau i te paipa me te hononga paipa i ngā āhuatanga mahi tino kino (te huame te whakamahi) kia pai ai te mahi mō te wā roa.

Ko ngā Whakamātautau Momo e taunakitia ana e ai ki te BS EN:545/598, ISO:2531 ko:

1. Te Pupuritanga o ngā Hononga ki te Pai, te Kino me te Hihiri o rotoTe pēhanga.
2. Te kikī o ngā hononga i te pēhanga pai o waho.
3. Te pūmau o te turuturu me te ātete ā-mīhini o ngā hononga piri.
4. Whakamātauria te Ātete ki te Waro.
5. Whakamātauria te Ātete Matū ki ngā Para.

Nā te British Standard Institute (BSI) i tirotiro ngā whakamātautau momo, ā, nā reirakua tukuna ngā Raihana 'KITEMARK'.
