ʻO ka paipu kila DN550 e pili ana i kahi paipu kila o kahi nui kiko'ī, kahi o "DN" ka pōkole o "Diameter Nominal",ʻo ia hoʻi ka "diameter nominal". ʻO ke anawaena nominal ka nui maʻamau i hoʻohana ʻia e hōʻike i ka nui o nā paipu, nā paipu paipu, a me nā kiwi. I ka ʻoihana paipu kila, he aha ke anawaena o waho o ka paipu kila DN550? ʻO ka pane ma kahi o 550 mm.

ʻO ka paipu kila he paipu metala maʻamau i hana ʻia me ke kila a hoʻohana nui ʻia i ke kūkulu ʻana, ka hana ʻana i nā mīkini, petrochemical, mana uila, aerospace, a me nā māla ʻē aʻe. Loaʻa i ka paipu kila ka maikaʻi o ka ikaika kiʻekiʻe, ke kūpaʻa corrosion, a me ke kūpaʻa wela kiʻekiʻe, no laila ua hoʻohana nui ʻia i nā papahana like ʻole a me nā noi.

Ma waho aʻe o ka nui o ke anawaena o waho o ka paipu kila DN550, hiki iā mākou ke hoʻomaopopo i kekahi mau mea nui e pili ana i nā paipu kila, e like me ka mānoanoa o ka paia, ka lōʻihi, a me nā mea.

1. ʻO ka mānoanoa o ka pā: ʻO ka mānoanoa o ka pā e pili ana i ka mānoanoa o ka paipu kila, i hōʻike pinepine ʻia ma nā millimeters a i ʻole iniha. ʻO ka mānoanoa o ka pā o ka paipu kila e pili kokoke ana i kona anawaena, a ʻo nā hiʻohiʻona noiʻi like ʻole a me nā koi ʻē aʻe nā koi like ʻole no ka mānoanoa o ka pā.
2. Ka lōʻihi: ʻO ka lōʻihi o nā paipu kila e hoʻohālikelike pinepineʻia, aʻo nā lōʻihi maʻamau he 6 mika, 9 mika, 12 mika, a me nā mea'ē aʻe.
3. Mea Hana: Nui nā ʻano mea no nā paipu kila, a ʻo nā mea maʻamau ʻo nā paipu kila carbon, nā paipu kila kila, nā paipu kila kila, a me nā mea ʻē aʻe. Ke kohoʻana i nā paipu kila, pono e hana i nā koho kūpono e pili ana i nā koi hoʻohana kūikawā.

Ma hope o ka hoʻomaopopo ʻana i ka ʻike kumu o ke anawaena o waho o ka paipu kila DN550, hiki iā mākou ke ʻimi hou i kekahi mau kumuhana e pili ana i nā paipu kila, e like me ke kaʻina hana, hoʻohana, a me ka noi mākeke.
1. Ke kaʻina hana: ʻO ke kaʻina hana o nā paipu kila ka nui o nā paipu ʻole a me nā paipu welded. Hana ʻia nā paipu ʻole ma ka hoʻomehana ʻana i ka billet kila i kahi mahana a laila hoʻopololei a ʻā paha. Loaʻa iā lākou ka ikaika kiʻekiʻe a me ka sila. Hana ʻia nā paipu welded ma ke kuʻi ʻana i nā pā kila i nā ʻano tubular a laila wili iā lākou. He mea maʻalahi ka hana hana a he haʻahaʻa ke kumukūʻai.
2. Hoʻohana: He nui ka hoʻohana ʻana o nā paipu kila. Hiki ke hoʻohana ʻia no ka lawe ʻana i nā wai, nā kinoea, a me nā mea paʻa, a hiki ke hoʻohana ʻia e kūkulu i nā hale like ʻole a me nā kākoʻo. No ka laʻana, i ka ʻoihana petrochemical, hoʻohana nui ʻia nā paipu kila no ka lawe ʻana i ka aila, ke kinoea maoli, a me nā huahana kemika; i ka ʻoihana hana, hoʻohana ʻia nā paipu kila no ke kūkulu ʻana i nā hale kila, kākoʻo i nā alapiʻi halihali ukana, etc.
3. Ke koi o ka mākeke: Me ka hoʻomohala ʻana o ka hoʻokele waiwai a me ka holomua o ka ʻoihana, ua hoʻonui ʻia ka noi mākeke no nā paipu kila i kēlā me kēia makahiki. ʻOi aku ka nui o ke kūkulu ʻana i nā ʻoihana, ke kūlanakauhale, a me ka hoʻomohala ʻana i nā ʻoihana, aia kahi koi nui no nā paipu kila. No laila, ʻo ka ʻoihana paipu kila he ʻoihana me ka hiki a me ka hoʻokūkū.

I ka hōʻuluʻulu ʻana, ʻo ke anawaena o waho o ka paipu kila DN550 ma kahi o 550 mm. He paipu kila maʻamau ia a hoʻohana nui ʻia i nā ʻano āpau. Pono ka poʻe o ka ʻoihana kila e hoʻomaopopo i nā kikoʻī o nā paipu kila, e kōkua ana i ke koho ʻana i nā paipu kila kūpono a loaʻa i nā hopena maikaʻi loa i nā noi kūpono. Me ka uluʻana o ka hoʻokele waiwai a me ka holomua o kaʻenehana, e hoʻomau ka uluʻana o kaʻoihana paipu kila a hoʻokō i ka koi no nā paipu kila ma nāʻano likeʻole. E nānā mākou i mua i ka ʻoihana paipu kila e hana ana i kahi ʻoi aku ka maikaʻi o ka wā e hiki mai ana!
