ʻO ka ʻōwili wela ST37 ST52 1020 1045 A106B ʻO ka paipu hao hao ʻole.

Paipu kila kalapona Kinahe paipu metala i haku ʻia me nā mea kalapona a me ka hao. Loaʻa iā ia nā ʻano penei:
Ka ikaika kiʻekiʻe a me ka paʻakikī. Hiki i nā paipu kila kalapona ke kū i ke kaumaha a me ke kaumaha nui, e hāʻawi iā lākou i ka hana maikaʻi i ka hana ʻana a me ka lawe ʻana i nā wai a me nā kinoea.
ʻO ka paʻakikī maikaʻi.Paipu kila kalapona ʻeleʻeleʻo ia ka paʻakikī maikaʻi a me ke kūpaʻa ʻana a kūpono no ka lawe ʻana i nā wai wela a me ke anuanu a me nā mea abrasive.
ʻO ka pale ʻana i ka corrosion ikaika. Hiki ke hoʻohana ʻia nā paipu kila kalapona i nā wahi ʻino like ʻole, akā nāwaliwali ko lākou pale ʻana i ka corrosion a ua maʻalahi lākou i ka ʻino ʻia e ke kaiapuni waho. ʻOi loa ke hoʻohana ʻia i loko o ka media corrosive humid, hiki lākou i ka corrosion a me ka ʻōpala.
Maikaʻi ka hana ʻana. He mea maʻalahi ka hana a me ka hoʻopilikino ʻana i nā paipu kila kalapona, hiki ke hana ʻia a hoʻopili ʻia ma o ka welding, threaded pili, etc., a loaʻa ka plasticity maikaʻi.
Hoʻokele waiwai maikaʻi. He haʻahaʻa ke kumukūʻai o nā paipu kila kalapona a ʻoi aku ke kumukūʻai.
Hoʻohana nui ʻia nā paipu hao kalapona i ka ʻaila, ke kinoea maoli, ka ʻoihana kemika, ka aerospace, ka mokulele, ka mīkini hana a me nā ʻano ʻē aʻe. Hoʻohana ʻia lākou i ke kūkulu ʻana, ka hana moku, nā alahaka a me nā māla ʻē aʻe, ʻoi aku ka hana nui i ka lawe ʻana i nā wai a me nā kinoea.
