Nā Paipu Hoʻopaʻa Piula No nā Paipu Wai Nui
I ke kūkulu ʻana i nā ʻoihana, he mea koʻikoʻi nā mea i hoʻohana ʻia i ka lōʻihi a me ka hana o ka papahana.ʻO kekahi mea pono i ka ʻoihana ʻoihana ʻo ia ka paipu welded spiral.Hoʻohana maʻamau ʻia kēia mau paipu i nā ʻano noi like ʻole e like me ke kumu wai a me nā paipu kinoea, a ʻo kā lākou mau kikoʻī, me nā paipu seam welded a me spiral, he mea koʻikoʻi i ka hōʻoia ʻana i kā lākou hana.Ma kēia blog, e nānā hohonu mākou i kakikoo paipu wiliwili spirala me ko lākou koʻikoʻi i ka ʻoihana kūkulu hale.
Spaipu hili piralskūkulu ʻia me ka hoʻohana ʻana i ke ʻano i kapa ʻia ʻo ke kaʻina hoʻoheheʻe spiral.ʻO ke kaʻina hana e pili ana i ka hoʻohana ʻana i nā wili wela o ke kila e hana ʻia i ke ʻano cylindrical a laila wili ʻia me kahi wili spiral.ʻO ka hopena he paipu me ka ikaika kiʻekiʻe a me ka lōʻihi, e kūpono ana ia no ka nui o nā noi.Hoʻohana kēia mau paipupaipu wiliwiliʻenehana i ka wā o ke kūkulu ʻana, e hōʻoia ana ua kūpaʻa lākou i nā ʻano like ʻole o ke kaiapuni a me nā koʻikoʻi, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i lalo a me lalo o ka wai.

I ka noʻonoʻo ʻana i nā kikoʻī no ka paipu spiral seam, he mea nui ka nānā ʻana i nā mea nui e like me ke anawaena, ka mānoanoa o ka paia a me ka pae waiwai.ʻO ke anawaena o ka paipu e hoʻoholo ai i kona hiki ke lawe i ka wai a i ʻole ke kinoea, ʻoiai ʻo ka mānoanoa o ka pā he kuleana koʻikoʻi i kona kūpaʻa a me ke kūpaʻa paʻa.Eia hou, hōʻike ka pae waiwai i ka maikaʻi a me ka hoʻohui ʻana o ke kila i hoʻohana ʻia a he mea nui e noʻonoʻo ai i ka lōʻihi o ka ola a me ka hana o ka paipu i kahi noi i hāʻawi ʻia.
I ke kukulu ana opaipu wai nui, He nui nā pono o nā paipu seam spiral.ʻO ko lākou ikaika tensile kiʻekiʻe a me ka pale ʻana i ka corrosion e kūpono iā lākou no ka lawe ʻana i ka wai ma kahi lōʻihi, ʻoiai ʻo kā lākou maʻalahi e hiki ai ke hoʻokomo maʻalahi a puni nā mea pilikia a me nā ʻāina paʻakikī.Eia kekahi, ʻo ka hoʻohana ʻana i nā paipu spiral seam i loko o nā pipeline gas kūlohelohe e hōʻoia i ka palekana a me ka maikaʻi o ka lawe ʻana i ke kinoea maoli, e hāʻawi ana i kahi waiwai nui no nā ʻāpana noho, ʻoihana a me nā ʻoihana.
Ma ka ʻaoʻao ʻoihana, hoʻokele ʻia nā kikoʻī pilipili seam pipe e nā kūlana ʻoihana a me nā lula 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 spiral-seam e kuhikuhi ana i nā koi no ka nui, ikaika, a me nā kaʻina hana hoʻāʻo.Eia kekahi, hāʻawi ka American Society for Testing and Materials (ASTM) i ka haku mele a me nā kikoʻī waiwai mechanical no nā paipu seam spiral e hōʻoia hou i ko lākou hilinaʻi a me ka hoʻokō ʻana i nā kūlana ʻoihana.
