Nā Paipu Welded Spiral no nā Paipu Kinoea Kūlohelohe
Paipu wiliwili, i ʻike ʻia hoʻiʻōmolehoʻopili ʻia, ua hana ʻia me ka hoʻohana ʻana i ka ʻenehana kuʻihao holomua e hana i kahi huahana ikaika. Loaʻa iā ia kahi hui wili mau i hana ʻia e ka wili ʻana i nā ʻāpana kila. Hāʻawi kēia ʻano kū hoʻokahi i ka ikaika i hiki ʻole ke hoʻohālikelike ʻia, e kūpono ana no nā noi koi e like menā laina kinoea kūlohelohe.
ʻO kekahi o nā hoʻohana nui o ka paipu wiliwili i hoʻopaʻa ʻia ʻo ia ka halihali kinoea kūlohelohe. Ua hoʻolālā kūikawā ʻia a hana ʻia e kū i nā wahi kaomi kiʻekiʻe e pili ana i ka hoʻoili ʻana o ke kinoea kūlohelohe. Hōʻoia nā paipu wiliwili i ka lawe palekana a me ka pono o ke kinoea kūlohelohe i nā ʻoihana a me nā mea kūʻai aku, e hōʻoia ana i kahi lako hilinaʻi a me ka hoʻēmi ʻana i nā leaka a i ʻole nā pōʻino.
