Nā Paipu Humuhumu ʻŌwili no nā Paipu Wai Nui

Wehewehe Pōkole:

I ke kūkulu ʻana i nā ʻoihana kūkulu hale, he kuleana koʻikoʻi nā mea i hoʻohana ʻia i ka lōʻihi o ka hana a me ka hana o ka papahana. ʻO kahi mea pono ʻole i ka ʻoihana ʻoihana kūkulu hale, ʻo ia ka paipu wiliwili. Hoʻohana pinepine ʻia kēia mau paipu i nā ʻano hana like ʻole e like me nā paipu wai a me nā paipu kinoea, a ʻo kā lākou mau kikoʻī, me nā paipu wiliwili a me nā paipu wiliwili, he mea nui ia no ka hōʻoia ʻana i kā lākou hana. Ma kēia blog, e nānā pono mākou i kaka hoʻākāka ʻana o ka paipu wiliwili a me ko lākou koʻikoʻi ma ka ʻoihana kūkulu hale.

I ke kūkulu ʻana i nā ʻoihana kūkulu hale, he kuleana koʻikoʻi nā mea i hoʻohana ʻia i ka lōʻihi o ka hana a me ka hana o ka papahana. ʻO kahi mea pono ʻole i ka ʻoihana ʻoihana kūkulu hale, ʻo ia ka paipu wiliwili. Hoʻohana pinepine ʻia kēia mau paipu i nā ʻano hana like ʻole e like me nā paipu wai a me nā paipu kinoea, a ʻo kā lākou mau kikoʻī, me nā paipu wiliwili a me nā paipu wiliwili, he mea nui ia no ka hōʻoia ʻana i kā lākou hana. Ma kēia blog, e nānā pono mākou i kaka hoʻākāka ʻana o ka paipu wiliwilia me ko lākou koʻikoʻi ma ka ʻoihana kūkulu hale.

Spaipu humuhumu piralsua kūkulu ʻia me ka hoʻohana ʻana i kahi ʻano i kapa ʻia ʻo ke kaʻina hana kuʻi spiral. Pili ke kaʻina hana i ka hoʻohana ʻana i nā wili kila i ʻōwili wela ʻia e hana ʻia i loko o kahi ʻano cylindrical a laila kuʻi ʻia ma kahi humuhumu spiral. ʻO ka hopena he paipu me ka ikaika kiʻekiʻe a me ke kūpaʻa, e kūpono ana no nā ʻano hana like ʻole. Hoʻohana kēia mau paipupaipu i hoʻopili ʻiaʻenehana i ka wā o ke kūkulu ʻana, e hōʻoiaʻiʻo ana he kūpaʻa lākou i nā ʻano kumu like ʻole o ke kaiapuni a me nā kaomi, e kūpono ai lākou no ka hoʻohana ʻana ma lalo o ka honua a me lalo o ka wai.

I ka noʻonoʻo ʻana i nā kikoʻī no ka paipu humuhumu wili, he mea nui e kālele i nā mea nui e like me ke anawaena, ka mānoanoa o ka paia a me ke ʻano o ka mea. ʻO ke anawaena o kahi paipu e hoʻoholo ai i kona hiki ke lawe i kahi wai a kinoea paha, ʻoiai ʻo ka mānoanoa o ka paia e pāʻani i kahi kuleana koʻikoʻi i kona kūpaʻa kūkulu a me ke kūpaʻa ʻana i ke kaomi. Eia kekahi, hōʻike ka ʻano o ka mea i ka maikaʻi a me ka haku mele ʻana o ke kila i hoʻohana ʻia a he mea nui ia e noʻonoʻo ai i ka hōʻoia ʻana i ka lōʻihi a me ka hana o ka paipu i kahi noi i hāʻawi ʻia.

Ma ke kūkulu ʻana onā paipu wai nui, he nui nā pono o nā paipu humuhumu wili. ʻO ko lākou ikaika tensile kiʻekiʻe a me ke kūpaʻa i ka pala e kūpono ai lākou no ka lawe ʻana i ka wai ma nā wahi lōʻihi, ʻoiai ʻo ko lākou maʻalahi e ʻae ai i ka hoʻonohonoho maʻalahi a puni nā pilikia a ma nā ʻāina paʻakikī. Eia kekahi, ʻo ka hoʻohana ʻana i nā paipu humuhumu wili i nā paipu kinoea kūlohelohe e hōʻoiaʻiʻo ana i ka halihali palekana a me ka pono o ke kinoea kūlohelohe, e hāʻawi ana i kahi kumuwaiwai koʻikoʻi no nā ʻāpana noho, kalepa a me nā ʻoihana.

Ma ka ʻaoʻao o ke kahua, ua hoʻomalu ʻia nā kikoʻī o ka paipu wiliwili e nā kūlana a me nā lula o ka ʻoihana e hōʻoia i ko lākou maikaʻi a me ka hana. No ka laʻana, ua hoʻomohala ka American Petroleum Institute (API) i nā kūlana no ka hana ʻana a me ka hoʻohana ʻana i ka paipu wiliwili-seam e wehewehe ana i nā koi no ka nui, ka ikaika, a me nā kaʻina hana hoʻāʻo. Eia kekahi, hāʻawi ka American Society for Testing and Materials (ASTM) i nā kikoʻī o ka hoʻohuihui mea a me nā waiwai mechanical no nā paipu wiliwili e hōʻoia hou i ko lākou hilinaʻi a me ka hoʻokō ʻana me nā kūlana o ka ʻoihana.

I ka hōʻuluʻulu manaʻo, he mea koʻikoʻi ka hoʻākāka ʻana o ka paipu wiliwili i kā lākou kuleana i ke kūkulu ʻana i nā pono hana. Inā hoʻohana ʻia no nā paipu wai a i ʻolenā laina kinoea, hāʻawi kēia mau paipu i ka ikaika, ka lōʻihi a me ka versatility i kūlike ʻole, e lilo ai lākou i mea nui loa i ke ao hou. Ma ka pili ʻana i nā kūlana ʻoihana a me nā lula, ʻo ka hoʻohana ʻana i nā paipu seam spiral e hōʻoiaʻiʻo ana i ka palekana a me ka pono o nā ʻōnaehana ʻōnaehana koʻikoʻi, e hoʻomākaukau ana i ke ala no ka hoʻomohala mau a me ka holomua o ka nohona.
