Paipu kila ʻōwilihe ʻano paipu kila i hana ʻia ma ka ʻōwili ʻana i kahi ʻāpana kila i loko o ke ʻano paipu ma kahi kihi wili (e hana ana i ke kihi) a laila e hoʻopili ai. Hoʻohana nui ʻia ia i nā ʻōnaehana paipu no ka hoʻoili ʻana o ka ʻaila, ke kinoea kūlohelohe a me ka wai.
Anawaena Inoa (DN)
ʻO ke anawaena inoa e pili ana i ke anawaena inoa o kahi paipu, ʻo ia ka waiwai inoa o ka nui o ka paipu. No ka paipu kila wili, kokoke ke anawaena inoa i ke anawaena maoli o loko a i waho paha, akā ʻaʻole like.
Hoʻike pinepine ʻia e DN me kahi helu, e like me DN200, e hōʻike ana he 200 mm ka paipu kila maʻamau.
Nā pae anawaena maʻamau (DN):

3. Ka laulā anawaena nui (DN750 - DN1200):
DN750 (30 ʻīniha)
DN800 (32 ʻīniha)
DN900 (36 ʻīniha)
DN1000 (40 ʻīniha)
DN1100 (44 ʻīniha)
DN1200 (48 ʻīniha)
4. Ka laulā anawaena nui loa (DN1300 a ma luna):

OD a me ID
Anawaena Waho (OD):
ʻO OD ke anawaena o ka ʻili waho o ka paipu kila wili. ʻO ka OD o kahi paipu kila wili ka nui maoli o waho o ka paipu.
Hiki ke loaʻa ka OD ma o ke ana maoli a ua ana pinepine ʻia ma millimeters (mm).
Anawaena Kūloko (ID):
ʻO ID ke anawaena o loko o ka paipu kila wili. ʻO ka ID ka nui maoli o loko o ka paipu.
ʻO ka maʻamau, helu ʻia ka ID mai ka OD me ka hoʻemi ʻana i ka mānoanoa o ka paia i ʻelua millimeters (mm).
ID=OD-2×mānoanoa o ka paia
Nā noi maʻamau
He ʻokoʻa nā noi o nā paipu kila wili me nā diameters inoa like ʻole ma nā ʻano like ʻole:
1. Paipu kila wili liʻiliʻi (DN100 - DN300):
Hoʻohana pinepine ʻia i ka ʻenekinia kūlanakauhale no nā paipu wai, nā paipu hoʻokahe, nā paipu kinoea, a pēlā aku.
2. paipu kila wili waena waena (DN350-DN700): hoʻohana nui ʻia i ka ʻaila, ka paipu kinoea kūlohelohe a me ka paipu wai ʻoihana.
3. paipu kila wili nui ke anawaena(DN750 - DN1200): hoʻohana ʻia i nā papahana hoʻoili wai mamao loa, nā paipu aila, nā papahana ʻoihana nui, e like me ka halihali waena.
4. paipu kila wili nui loa (DN1300 a ma luna): hoʻohana nui ʻia no nā papahana paipu wai, aila a me ke kinoea mamao loa, nā paipu wai ma lalo o ka wai a me nā papahana ʻoihana nui ʻē aʻe.
Nā kūlana a me nā loina
ʻO ke anawaena inoa a me nā kikoʻī ʻē aʻe o ka paipu kila wili e hana pinepine ʻia e like me nā kūlana a me nā loina pili, e like me:
1. Nā kūlana honua:
API 5L: pili i ka paipu kila halihali pipeline, e kuhikuhi ana i ka nui a me nā koi mea o ka paipu kila wili.
ASTM A252: pili i ka paipu kila kūkulu, ka nui o ka paipu kila wili a me nā koi hana.
2. Kūlana Lahui:
GB/T 9711: pili i ka paipu kila no ka halihali ʻana i ka ʻoihana aila a me ke kinoea, kuhikuhi i nā koi loea o ka paipu kila wili.
GB/T 3091: pili i ka halihali wai haʻahaʻa me ka paipu kila i hoʻopili ʻia, kuhikuhi i ka nui o ka paipu kila wili a me nā koi loea.
