ʻO ka paipu kuʻikuʻi kila ʻole au ʻike

hoʻolauna pōkole:

ʻO ka paipu kila maʻemaʻe ʻole he kila lōʻihi me ka ʻāpana ʻāwaha a ʻaʻohe ami a puni.He paipu kila ia e kū'ē i nā mea hoʻoheheʻe nāwaliwali e like me ka ea, ka mahu, a me ka wai, a me nā mea hoʻoheheʻe kemika e like me ka waikawa, ka alkali, a me ka paʻakai.ʻIke ʻia hoʻi he paipu kila ʻakika-kūpono.

ʻO nā hiʻohiʻona o ke kila kila ʻole:

ʻO ka mea mua, ʻoi aku ka mānoanoa o ka pā o ka paipu kuhili ʻole, ʻoi aku ka maikaʻi a me ka hana, a ʻoi aku ka lahilahi o ka mānoanoa o ka pā, ʻoi aku ka nui o ke kumukūʻai hana;ʻO ka lua, ʻo ka ʻenehana o ka huahana e hoʻoholo i kona mau palena ʻO ka mea maʻamau, ʻoi aku ka haʻahaʻa o ka pololei o nā paipu kila maʻemaʻe: ʻaʻohe mānoanoa o ka paia, haʻahaʻa haʻahaʻa ma loko a ma waho o ka paipu, ke kumu kūʻai kiʻekiʻe o ka nui, a aia nā lua a me nā kikoʻeleʻele ma luna. ʻo loko a me waho i maʻalahi ʻole e wehe;ʻO ka hope, pono e hoʻopaʻa ʻia kona nānā ʻana a me kona hoʻohua ʻana.No laila, hōʻike ia i kona kūlana kiʻekiʻe ma ke ʻano o ke kaomi kiʻekiʻe, ka ikaika kiʻekiʻe, a me nā mea hana mechanical.

Nā noi paipu ʻole kila kila: 

ʻOi aku ka maʻalahi o nā paipu kuhili ʻole i ke kaumaha i ka wā e like ai ke kulou a me ka ikaika torsional, no laila ua hoʻohana nui ʻia lākou i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia.Hoʻohana pinepine ʻia ia e hana i nā mea kaua maʻamau, nā barela, nā pūpū, a me nā mea ʻē aʻe.ʻO nā paipu paʻa lahilahi a me ka hoʻomohala kūleʻa o nā ala pili pono, maʻalahi a maʻalahi hoʻi e loaʻa iā lākou nā pono kūpono ʻole no nā paipu ʻē aʻe, a ʻoi aku ka nui o kā lākou noi i ka ʻenekinia., e lilo ana ka hoʻohana i mea kaulana loa, a ke hoʻohiki nei nā manaʻo.

ʻO ka pale ʻana i ka corrosion o nā paipu seamless kila ma muli o nā mea hoʻohui i loko o ke kila.ʻO Chromium ka mea kumu no ke kila kila e loaʻa ai ke kūpaʻa corrosion.Ke piʻi ka maʻiʻo o ka chromium i ke kila ma kahi o 12%, chromium a me ka oxygen i loko o ka corrosive medium e hana i kahi kiʻi ʻoniʻoni lahilahi (self-passivation film) ma ka ʻili o ke kila., hiki ke pale aku i ka corrosion hou aku o ka matrix kila.Ma waho aʻe o ka chromium, ʻo nā mea hoʻohui maʻamau i hoʻohana ʻia no nā paipu seamless steel he nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., e hoʻokō i nā koi o nā hoʻohana like ʻole no ke ʻano a me nā waiwai o ke kila kila.
