Nā Pono a me nā pōʻino o ka paipu keleawe
ʻO ka paipu keleawe ka mea koho mua no nā paipu no ka mea nona nā waiwai ikaika. He hilinaʻi loa, kūpaʻa, a kū i ka corrosion. ʻO kēia mau mea kūʻai kumukūʻai he malleable loa a hōʻike i kahi ʻili maʻemaʻe e ʻae i ka holo mālie o nā wai i loko o ka ʻōnaehana.
Pono ke keleawe i ka mālama nui ʻana no ka mea hiki ke ʻike ʻia i ka ʻeleʻele ʻeleʻele. ʻAʻole ʻōlelo ʻia no nā kaomi ma luna o 300 PSIG. E nāwaliwali kēia mau ʻāpana a hāʻule paha i nā mahana ma luna o 400 degere F. I ka wā lōʻihi, hiki ke hoʻololi ʻia ka zinc i haku ʻia i loko o ka paipu i zinc oxide-hoʻokuʻu i kahi pauka keʻokeʻo. Hiki i kēia ke hoʻopili i ka paipu. I kekahi mau hihia, hiki ke hoʻonāwaliwali ʻia nā ʻāpana keleawe a hopena i nā māwae pin-hole.
