ʻO ke kola wili maʻamau ka ʻāpana keʻa poepoe, aia kahi lua wai ma ke kikowaena, ʻoi aku ka mānoanoa o ka paia, ʻoi aku ka liʻiliʻi o ka nozzle, ʻoi aku ke kaumaha o kēlā me kēia lōʻihi ma mua o ka nui o ka paipu wili kokoke i 4-5 mau manawa. ʻO ka hapa nui o ke kola wili he hana kaula pololei ma ke kino paipu, akā hoʻohana pū kekahi o lākou i ka hui i pani ʻia.
ʻO ke kola wiliwili kahi ʻano mea hana wili petroleum. Hiki i kēia ʻano kola wili ke pale i ka paʻa ʻana o ke kaomi ʻokoʻa o nā mea hana i ka wā wili. E hiki ai i nā ʻauwaha wili ke kahe manuahi a puni ke kola wili e hoʻohana i ke kaomi kaulike e pale i ke kūkulu ʻia ʻana o ka pale ʻana i mea e pale pono ai i ke kaomi ʻokoʻa. Hiki ke ʻoki ʻia ka wahi pili i ka paia o ka luawai i mea e hōʻemi pono ai i ka hiki ke hana i ke keakea kaomi ʻokoʻa. E hiki ai i nā ʻauwaha wiliwili ke kahe manuahi a puni ke kola wili e hoʻohana i ke kaomi kaulike e pale i ke kūkulu ʻia ʻana o ka pale ʻana i mea e pale pono ai i ke keakea kaomi ʻokoʻa. Hiki ke ʻoki ʻia ka wahi pili i ka paia o ka luawai i mea e hōʻemi pono ai i ka hiki ke hana i ke keakea kaomi ʻokoʻa. ʻO ke kaumaha o ke kola wiliwili he 4-6% ka emi ma mua o ke kola wili poepoe.
ʻO ke kola wili ʻole-magnetic: Hana ʻia nā kola wili ʻole-magnetic mai nā mea kola wili ʻole-magnetic me ka ikaika haʻahaʻa ma o ka hoʻohui ʻana i kahi loiloi kemika ponoʻī a me ke kaʻina hana hana hāmare rotary me ka permeability magnetic haʻahaʻa maikaʻi loa o ka mīkini. hiki iā mākou ke hoʻolako i nā lōʻihi mai 10 a 42 kapuaʻi a me ke anawaena o waho mai 31/8" a 11'.

Ua hōʻoia ʻia kahi pae paʻakikī o 285 a 341 BHN a me kahi waiwai hopena Charpy o 40 ft-lbs no ka hoʻokaʻawale like ʻana o 16 mau kiko i kekahi mau ʻāpana kea ma ka mahana o ka lumi;
Ua uhi ʻia nā pilina me ka phosphate ma hope o ka mīkini ʻana e pale i nā kaula mai nā mea ʻino a e pale aku i ka ʻeha i ka wā e hoʻoponopono mua ai;
Ua ʻōwili anu ʻia nā aʻa kaula ma nā pilina API;
Hoʻolako ʻia nā pale kaula kila i kaomi ʻia no nā kola wili a pau i lako me nā pilina maʻamau.
Nā koho
ʻAuwai hoʻomaha koʻikoʻi. Nā hiʻohiʻona hoʻomaha koʻikoʻi ma nā pilina pine a me ka pahu API e hōʻemi i nā ʻano koʻikoʻi kiʻekiʻe a pēlā e hoʻomaikaʻi ai i ka ikaika kulou a puni nā wahi pili.
Ua hōʻike mai ke ʻōwili anu ʻana o ke aʻa kaula i nā hopena maikaʻi e hoʻomaikaʻi ai i ke kūpaʻa luhi o nā pilina ma ka hoʻēmi ʻana i ka hoʻomaka ʻana o nā māwae.
ʻO ke kāpili paʻakikī. ʻO ke kāpili paʻakikī ma nā wahi ma lalo a ma luna o ka slip recess a i ʻole ma ka poʻohiwi pine e hoʻolōʻihi i ke ola lawelawe o nā kola wili. Hiki ke hoʻopili ʻia ma nā hoʻonohonoho i kuhikuhi ʻia e nā mea kūʻai aku. ʻO ke kāpili paʻakikī ma nā wahi ma lalo a ma luna o ka slip recess a i ʻole ma ka poʻohiwi pine e hoʻolōʻihi i ke ola lawelawe o nā kola wili.
