Pehea e hōʻoia ai i ka mānoanoa o ka zinc coating e hoʻokō i kāu mau koi papahana?
No ka meapaipu kila galvanized, ho'oikaika 'ia ka pale 'ino - lō'ihi eka mānoanoa o ka uhi zinc a me ke kaʻina hana. Pono e koho ʻia ke ʻano galvanizing kūpono e like me ke kaiapuni kahi e kau ʻia ai ka pipeline.
No ka meanā kaiapuni ʻino loa- e like me nā paepae o waho, nā kūkulu kahakai a i ʻole nā ʻāpana splash - manaʻo mākouhoʻopaʻa haʻahaʻa -wela welame ka uhi paona o500 g/m² a ma luna. Hāʻawi kēia ʻāpana zinc ʻoi aku ka nui o ke ola i loko o nā lewa moana, nā ʻaʻahu o waho, nā paipu jetty, nā paipu paipu i loko o nā hale hoʻomaʻemaʻe a me nā mea hao i ʻike ʻia.
No nā pūnaewele hoʻolako wai o ke kūlanakauhale, nā laina pale ahi a me nā laina paipu ʻoihana maʻamau, ua lawa ka maʻamau maʻamau -pepa galvanized ma kahi o 300 g/m². ʻO kēia pae palekana e kūpono i ka hapa nui o nā laina wai o ke kūlanakauhale, nā lawelawe hale paipu, ka sprinkler ahi a me nā ʻōnaehana hydrant, e hāʻawi ana i ka paʻa maikaʻi ma ke kumukūʻai kūpono.
No ka nui -volume, -palapala pālākiō e like me nā hana no ka manawa lō'ihi, ka hā'awi 'ana i ka wai kua'āina a i 'ole ka hana 'ana māmā, mua-ka'ili hao (pahu paipu galvanized) ma ka laulā o 60–150 g/m² hiki ke koho waiwai. He kūpono kēia mau paipu galvanized i ka wā maʻalahi ke ola o ka hoʻolālā ʻana a me ka hoʻolaha ʻana a ʻae ʻia ka hoʻololi ʻana a i ʻole redundancy.
Ma ka hoohalike anaka mānoanoa o ka zinc coatingakaʻina hana galvanizingi ka ʻāpana corrosion maoli o kāu papahana, hiki iā ʻoe ke hoʻolōʻihi i ke ola lawelawe, pale i nā hāʻule mua a mālama i nā kumukūʻai mālama.
Pehea e koho ai i ke kūlana paipu galvanized kūpono no kāu papahana?
Hoʻoholo ka maʻamau āu e koho aika mānoanoa o ka paia, nā waiwai mechanical a me ka liʻiliʻi o ka paona pani zinc, a he kumu nui i ka paʻa holoʻokoʻa o ka papahana a me ke kumukūʻai o ke ola.
No ka meahaʻahaʻa haʻahaʻa a hiki i ke kino corrosione like me nā hale kūʻai, -wai haʻahaʻa haʻahaʻa a me ka hāʻawi ʻana i ke kinoea, nā ʻupena sprinkler ahi a me nā ʻōnaehana HVAC,ASTM A53 paipu kila kilahoʻohana nui ʻia. Aia ma kahi o ka uhi hao wela ma'amau -no kēia ma'amau1.8 oz/ft² (≈0.55 kg/m²), i lawa no ka ʻike ʻana i loko a i ʻole ma waho.
No ka lawe ʻana i ka wai, nā laina hoʻokomo wai maka, nā kumu wai i kanu ʻia a me nā ʻōnaehana wai ʻino e ʻike mau ʻia i ka wai a me ka lepo, AWWA C200 a me nā kūlana hana wai e pili ana. Ma ʻaneʻi, ʻōlelo ʻia nā uhi zinc o 2.0 oz/ft² (≈0.61 kg/m²) a i ʻole ke kiʻekiʻe, e hāʻawi ana i ka pale ʻoi aku ka maikaʻi ma nā paipu wai o ke kūlanakauhale, nā laina wai a me nā wai ʻino, nā mea kanu lapaʻau a me nā keʻena pumping.
Ma muli o kāu papahana, hiki iā mākou ke hana iEN a i ʻole ISO galvanized pipe standardskahi e pili ai nā kuʻuna kūloko a i ʻole nā koi o ka mea kūʻai aku. ʻO kā mākou kuleana ke kōkua iā ʻoe e koho i ka maʻamau e kaulike ana:
- ola hoʻolālā pono
- kaiapuni (loko/waho, lepo, kai, ʻenehana)
- kaomi a me ka hoʻouka mechanical
- nā kūlana hoʻonohonoho a mālama
i paʻa paʻa kou ʻōnaehana paipu kila no ke ola o ka papahana holoʻokoʻa.
Pehea e hōʻoia ai i ka maikaʻi o ka paipu galvanized i nā koi o ka papahana?

Nā noi maʻamau - pehea e pale ai ka paipu galvanized i nā ʻāpana like ʻole
Mahalo i kona uhi zinc a me ke kino kila ikaika,paipu kila galvanizedhoʻohana nui ʻia i nā wahi a pau e pono ai ke koena o ka ikaika, ke kumu kūʻai a me ka pale ʻana i ka corrosion.
Aia nā hiʻohiʻona hoʻohana maʻamau:
- Ke kūkulu hale a me ke kūkulu ʻana
ʻO nā paipu ua wai o waho, nā lima lima, nā kaʻa kiaʻi, nā kākoʻo uwea a me nā lālā māmā i ʻike ʻia i ka wā. Hoʻemi ka paipu Galvanized i ka pena hou ʻana a me ka hoʻoponopono pinepine ʻana i nā envelopes a me nā facades.
- ʻO ka wai a me nā ʻōnaehana wai ʻino
ʻO ka hāʻawi ʻana i ka wai inu, nā kumu ahi, nā laina irrigation a me nā ʻāpana owai ʻino a me nā ʻupena waikahi e pono ai ka pale corrosion haʻahaʻa. Hoʻohana pinepine ʻia ka paipu galvanized ma nā ʻāpana o luna-ka honua, nā lumi pamu a me nā mea kanu lapaʻau.
- ʻO ka paipu pono hana ʻoihana
Ea kōmi ʻia, wai hoʻoluʻu, wai kaʻina hana haʻahaʻa -a me nā laina lawelawe maʻamau i nā hale hana a me nā mea kanu. Hāʻawi ka paipu kila Galvanized i ka pale paʻa i lokonā lewa ʻenehana, nā hale hana a me nā ʻauʻau paipu waho.
- ʻO ka waiho ʻana a me ka hoʻoili ʻana i ka aila
-ʻaila hoʻoili haʻahaʻa haʻahaʻa, diesel a me ka ʻaila hoʻoili a puni nā pahu pahu, nā ʻawa hoʻouka a me nā pahu. Hāʻawi ka paipu galvanized i ka hopena paʻa, maʻalahi-e-mālama ʻia no nā manifold waho, nā lima hoʻouka ʻana, nā pahū pahū a me nā ʻōnaehana aila pono e ʻike ʻia i ka haʻahaʻa a me ka pipiʻi i kekahi manawa.
- ʻO ka hāʻawi kinoea a me nā pūnaewele pono
ʻO ke kinoea maoli a me ka LPG haʻahaʻa haʻahaʻa haʻahaʻa i loko o nā hale a i ʻole nā ʻōnaehana mea kanu, kahi e ʻae ai nā code i ka paipu galvanized. Mālama ka zinc coatingma luna o-laina kinoea honua, ka holo mika a me ka paipu o loko mai ka condensation a me nā lewa ʻenehana haʻahaʻa.
- ʻO ka pā a me ka hana māmā
ʻO nā pou pā, nā pou hōʻailona, nā scaffolding a me nā hale kūʻokoʻa, ʻoi aku ma lokonā papahana kuaʻāina, mahiʻai a me nā ʻoihana, kahi e pono ai ka hoʻoponopono lōʻihi akā pono.
Ma ke koho ʻana i ka kikoʻī paipu galvanized kūpono a me ka pae uhi no kēlā me kēia hiʻohiʻona, hoʻomaikaʻi ʻoe i ka hilinaʻi ʻana o ka ʻōnaehana a hōʻemi i ka nui o ke kumukūʻai mālama.
No ke aha e koho ai iā mākou e like me kāu mea hoʻolako paipu kila
Ma ke ʻano he loeamea hoʻolako paipu kila galvanized, hana mākou ma mua o ke kūʻai aku ʻana i nā mea kikoʻī maʻamau. Kōkua mākou iā ʻoe e kūkulu i kahi hoʻonā e pili ana i kāu papahana:
- ʻO ka uhi zinc maʻamau a me ke koho kaʻina hana
ʻO ka wili wela -kaumaha no ka hoʻohana ʻana i waho a me ka moana, ka wela wela -maʻamau no ke kūkulu hale a me nā ʻōnaehana ʻoihana, a i ʻole ka -piu wili puʻupuʻu no ka nui-nui, koina-hana koʻikoʻi-i koho ʻia e like me kou kaiapuni a me ke ola hoʻolālā.
- Kūlike nā kūlana a me nā kikoʻī i kāu ʻāpana
Hāʻawi mākou i ka paipu galvanized iASTM A53, AWWA C200 a me nā kūlana pili, me ke kaumaha o ka uhi ʻana, ka pae mechanical a me ke ʻano hoʻāʻo i hoʻohālikelike ʻianā hana wai, nā lawelawe hale, nā pono aila a me ke kinoea a i ʻole nā mea kanu ʻoihana.
- Hoʻopau i ka hoʻopau ʻana a me ka hana ʻana i hoʻokahi pūʻolo
Hiki ke hoʻolako pū ʻia ka paipu galvanized threaded, grooved a beveled galvanized me nā hui like, flanges a me nā mea pono, e hōʻemi ana i ka hoʻohui ʻana ma waena o nā mea kūʻai aku he nui a wikiwiki ka hoʻonohonoho ʻana i ka pūnaewele.
- Hoʻopaʻa ʻia ka maikaʻi a me ke kākoʻo ʻenehana
Loaʻa iā ʻoe nā palapala hoʻāʻo piha a me nā moʻolelo uhi, me ke kākoʻo ʻenekinia ma ke koho ʻana i ka uhi, nā koho maʻamau a me nā hiʻohiʻona noiʻi, no laila hiki i kāu hui ke hōʻoia i nā hoʻoholo i nā mea nona a me nā kūkākūkā.
Me kā mākoupaipu galvanized paipu ma'amau, hiki iā ʻoe ke kuhikuhi pono i kāu mea e pono ai no kēlā me kēia pāhana-ka mānoanoa o ka uhi ʻana, ka maʻamau, ka hoʻopau ʻana a me ka hoʻopili ʻana-a loaʻa i kahi pūʻolo i mākaukau e hoʻouka, paʻa i ka lawelawe a maʻalahi hoʻi ka mālama ʻana no ka wā lōʻihi.
