Ma ka ʻōlelo maʻamau, hiki ke hoʻokaʻawale ʻia ke anawaena o ka paipu i loko o ke anawaena o waho (De), ke anawaena o loko (D), ke anawaena nominal (DN).
Ma lalo e hāʻawi iā ʻoe i kahi ʻokoʻa ma waena o kēia ʻokoʻa "De, D, DN".
ʻO DN ke anawaena inoa o ka paipu
Nānā: ʻAʻole kēia ke anawaena o waho a ʻaʻole hoʻi ke anawaena o loko; pono e pili i ka hoʻomohala mua ʻana o ka ʻenekinia pipeline a me nā ʻāpana imperial; hoʻohana pinepine ʻia e wehewehe i ka paipu kila galvanized, e pili ana i nā ʻāpana imperial penei:
4-hapa paipu: 4/8 iniha: DN15;
6-minuke paipu: 6/8 iniha: DN20;
1 iniha paipu: 1 iniha: DN25;
ʻElua ʻīniha paipu: 1 a me 1/4 iniha: DN32;
ʻO ka paipu hapalua ʻīniha: 1 a me 1/2 iniha: DN40;
ʻElua iniha paipu: 2 iniha: DN50;
ʻEkolu-ʻīniha paipu: 3 iniha: DN80 (nui nā wahi i kapa ʻia ʻo DN75);
ʻEhā-iniha paipu: 4 iniha: DN100;
Wai, paipu kila hoʻoili kinoea (paipu kila galvanizeda i ʻole paipu kila non-galvanized), paipu hao hao, paipu kila-plastic composite a me polyvinyl chloride (PVC) paipu a me nā mea paipu ʻē aʻe, e kaha ʻia me ke anawaena inoa "DN" (e like me DN15, DN20).
ʻO ka mea nui e pili ana i ke anawaena o waho o ka paipu
ʻO ka hoʻohana maʻamau o De labeling, pono e hoʻopaʻa inoa ʻia i ke ʻano o ke anawaena o waho X ka mānoanoa o ka paia;
Hoʻohana nui ʻia e wehewehe:paipu kila ʻole, PVC a me nā paipu plastik ʻē aʻe, a me nā paipu ʻē aʻe e pono ai ka mānoanoa o ka paia.
E lawe galvanized welded kila paipu e like me ka laʻana, me DN, De elua hana lepili 'ia penei:
DN20 De25×2.5mm
DN25 De32×3mm
DN32 De40×4mm
DN40 De50×4mm
......
ʻO D ka mea maʻamau i ke anawaena o loko o ka paipu, ʻo d e hōʻike ana i ke anawaena o loko o ka paipu koneki, a ʻo Φ ke anawaena o ka pōʻai maʻamau.
Hiki iā Φ ke kuhikuhi i ke anawaena o waho o ka paipu, akā pono e hoʻonui ʻia i ka mānoanoa o ka pā.
No ka la'ana, Φ25×3 'o ia ho'i he paipu me ke anawaena o waho he 25mm a he 3mm ka mānoanoa o ka paia.
ʻO ka paipu kila maʻemaʻe ʻole a i ʻole ka paipu metala non-ferrous, pono e kaha ʻia i ka "outer diameter × wall thickness".
No ka laʻana: Φ107×4, kahi hiki ke waiho ʻia ka Φ.
ʻO Kina, ISO a me Iapana ka ʻāpana o ka paipu kila e hoʻohana ana i nā ana mānoanoa o ka paia e hōʻike i ka mānoanoa o ka pā o ka paipu kila. No kēia ʻano paipu kila, ke ʻano o ka ʻōlelo no ka paipu ma waho o ke anawaena × pā mānoanoa. No ka laʻana: Φ60.5×3.8
De, DN, d, ф o ka laula o ka olelo!
De-- PPR, paipu PE, paipu polypropylene OD
DN -- ka paipu polyethylene (PVC), paipu hao hao, paipu hui kila-palaki, paipu kila galvanized nominal diameter.
d -- ke anawaena o ka paipu sima
ф -- paipu kila ʻole ke anawaena
