ʻO ke kala opaipu haopili pinepine i kā lākou hoʻohana ʻana, ka mālama anti-corrosion a i ʻole nā kūlana ʻoihana. Loaʻa i nā ʻāina a me nā ʻoihana like ʻole nā koi kikoʻī no nā kala e hōʻoia i ka palekana, ka pale ʻana i ka corrosion a i ʻole ka ʻike maʻalahi. Eia ka wehewehe kikoʻī:
1. Ke ano nui o DINSEN SML Pipe kala
·ʻeleʻele/ʻeleʻele hina/Ka hao kumu a i ʻole ka asphalt/ka uhi ʻana i ka corrosion Ka hoʻoheheʻe ʻana, ka ʻōpala, nā paipu kūloko
·ʻulaʻula/ʻO nā paipu ahi, ka pale wela kiʻekiʻe a i ʻole nā hōʻailona kūikawā/Pūnaehana ahi, hāʻawi wai kiʻekiʻe
·ʻōmaʻomaʻo/ʻO nā paipu wai inu, nā uhi ʻoluʻolu (e like me ka epoxy resin)/ʻO ka wai paipu, lako wai wai
·Polū/Wai ʻoihana, ea kōmi/Hale hana, ʻōnaehana ea kōmi
·Melemele/ʻO nā paipu kinoea (ʻoi aku ka hao, ka nui o nā paipu kila)/Hoʻouna kinoea (ke hoʻohana mau nei kekahi mau wahi i ka hao hao)
·Kālā kala/ʻO ka lāʻau anti-rust galvanized/Kaiapuni waho, humid, kiʻekiʻe corrosion koi kū'ē
2. Nā koi kūikawā no nā kala paipu hao ma nā mākeke kūloko a me nā ʻāina ʻē
(1) Makeke Kina (GB standard)
Nā Paipu Hao Waiwai: ʻeleʻele (asphalt anti-corrosion) a i ʻole hao hina hina, uhi ʻia me ka resin epoxy ('ōmaʻomaʻo).
Paipu Hao Waiwai:Paipu hao maʻamau: ʻeleʻele a ʻulaʻula paha (no ka pale ahi).
Paipu Hao Ductile (DN80-DN2600): pā i waho i kāpī ʻia me ka zinc + asphalt (ʻeleʻele), ka uhi o loko me ka sima a i ʻole ka epoxy resin (hina/'ōmaʻomaʻo).
ʻO ka paipu pale ahi: ka uhi ʻulaʻula, i ka laina me ka kikoʻī pale ahi o GB 50261-2017.
Paipu kinoea: melemele (akā, ua hana ʻia nā paipu kinoea hou i ka PE a i ʻole nā paipu kila, a ʻaʻole hoʻohana ʻia ka hao hao).
(2) Makeke US (AWWA/ANSI Standard)
AWWA C151 (paipu hao ductile):
ʻO ka paia o waho: ʻeleʻele maʻamau (ka uhi asphalt) a i ʻole ke kālā (galvanized).
ʻO ka uhi ʻana o loko: ka mīkini sima (hina) a i ʻole ka epoxy resin ('ōmaʻomaʻo/uliuli).
ʻO ka paipu pale ahi (NFPA standard): ʻulaʻula, pono kekahi i nā huaʻōlelo "FIRE SERVICE" e paʻi ʻia.
ʻO ka Pipe wai inu (NSF/ANSI 61 palapala hōʻoia): pono ka ʻili o loko e hoʻokō i nā kūlana maʻemaʻe, ʻaʻohe koi koi no ka waihoʻoluʻu o waho, akā hoʻohana pinepine ʻia ka logo ʻōmaʻomaʻo a polū paha.
(3) Makeke ʻEulopa (EN maʻamau)
EN 545/EN 598 (paipu hao ductile):
Anticorrosion waho: zinc + asphalt (ʻeleʻele) a i ʻole polyurethane ('ōmaʻomaʻo).
ʻO ka Lining i loko: ʻo ka mortar sima a i ʻole ka epoxy resin, ʻaʻohe kānāwai kala ʻokoʻa, akā pono e hoʻokō i nā kūlana wai inu (e like me ka palapala KTW).
Paipu ahi: ʻulaʻula (pono kekahi mau ʻāina e paʻi i ka "FEUER" a i ʻole "FIRE").
Pipe ʻOihana: ʻulaʻula paha (ea i hoʻopaʻa ʻia) a i ʻole melemele (gas, akā ua hoʻololi mālie ʻia nā paipu hao hao).
(4) Makeke Kepani (JIS standard)
JIS G5526 (paipu hao ductile): He ʻeleʻele ka pā o waho (asphalt) a i ʻole galvanized (kālā), a ʻo ka uhi o loko he sima a i ʻole resin.
Paipu ahi: pena ʻulaʻula, koi kekahi e paʻi i ka "kaua ahi".
ʻO ka paipu wai inu: ka ʻōmaʻomaʻo a i ʻole ka lole uliuli, e like me ka maʻamau JHPA.
3. ʻO ka mana o ke kala o nā pale anti-corrosion kūikawā
Epoxy resin coating: maʻamau ʻōmaʻomaʻo a uliuli paha, hoʻohana ʻia no nā koi anti-corrosion kiʻekiʻe (e like me ka wai kai, ʻoihana kemika).
ʻO ka uhi polyurethane: ʻōmaʻomaʻo paha, ʻeleʻele a melemele paha, me ke kū ʻana i ka wā ikaika.
Zinc + asphalt coating: ʻeleʻele ka paia o waho, kūpono no nā paipu kanu ʻia.
4. Summary: Pehea e koho ai i ke kala o nā paipu hao?
E koho ma ka hoʻohana ʻana:
ʻAi wai/wai → ʻeleʻele/hina
Ka wai inu → ʻōmaʻomaʻo/uliuli
Puhi ahi → ʻulaʻula
ʻOihana → ma ka ʻike maʻamau (e like me ke kinoea melemele, ea kōmi polū)
E koho ma ka maʻamau:
Kina (GB) → ʻeleʻele (drainage), ʻulaʻula (pā ahi), ʻōmaʻomaʻo (wai inu)
ʻEulopa a me ʻAmelika Hui Pū ʻIa (AWWA/EN) → ʻeleʻele (anti-corrosion waho), ʻōmaʻomaʻo/uliuli (lining)
Iapana (JIS) → ʻeleʻele (pā i waho), ʻulaʻula (pā ahi)
Inā ʻaʻole ʻoe maopopo i ke koho ʻana, e ʻoluʻolu e kelepona iā DINSEN
