I ka honua o ke kūkulu ʻana a me ka hoʻomohala ʻana i nā ʻoihana, ʻo ke koho ʻana i nā mea pono he mea koʻikoʻi.ʻO nā paipu kūkulu ʻāpana ʻāwaha he kuleana koʻikoʻi i ka hāʻawi ʻana i ka ikaika, kūpaʻa a me ka hilinaʻi i nā ʻano papahana like ʻole.Ma kēia blog, e ʻimi mākou i nā hiʻohiʻona a me nā pōmaikaʻi o ʻelua ʻano mea nui o ka paipu kūkulu: spiral submerged arc welded pipe a me API 5L line pipe.

Piula wiliwili ʻia i loko o ke ao:

Hoʻohana ʻia ka paipu submerged arc welded (SAW), i ʻike ʻia ʻo SSAW pipe, i nā ʻano hana like ʻole.ʻO ka hiʻohiʻona kūikawā opaipu SSAW ʻO ia kona mau humuhumu spiral, e hāʻawi ana i ka ikaika a me ka hiki ke amo i ka ukana ma mua o nā ʻano paipu ʻē aʻe.Kōkua kēia hoʻolālā kūʻokoʻa i ka puʻunaue like ʻana i ke koʻikoʻi i loko o ka paipu, i mea kūpono no nā papahana e koi ana i ka hoʻonohonoho pono.

No ka paipu PSL 2, e hoʻokumu a hahai ka mea hana i nā kaʻina hana i kākau ʻia no ka mālama ʻana i ka ʻike wela a me ka ʻike hoʻāʻo no ia paipu.E hāʻawi ia mau kaʻina hana i nā ala no ka ʻimi ʻana i ka lōʻihi o ka paipu i ka ʻāpana hoʻāʻo kūpono a me nā hopena hoʻokolohua pili.

ʻO kekahi o nā pōmaikaʻi nui o ka paipu SSAW ʻo kāna hana maʻalahi.Hiki ke hana ʻia kēia mau paipu i nā ʻano nui, nā anawaena a me nā mānoanoa a hiki ke hoʻopili ʻia e hoʻokō i nā koi o kahi papahana kikoʻī.Eia kekahi, ua hana mau ʻia nā paipu i hoʻopaʻa ʻia i loko o ka wai me ke kila kiʻekiʻe, e hana ana i ka corrosion-resistant a me ka hōʻoia ʻana i ke ola o ka lawelawe ʻana.

Paipu laina API 5L:

API 5L laina paipuhe paipu hollow pauku i hoʻohana nui ʻia e kū ana i nā kūlana American Petroleum Institute (API).Hoʻolālā ʻia kēia mau paipu e lawe i nā wai, e like me ka aila a me ke kinoea maoli, ma kahi lōʻihi.ʻIke ʻia ka paipu laina API 5L no kona ikaika kiʻekiʻe, kūpaʻa a me ke kūpaʻa ʻana i nā kūlana kūlohelohe.

ʻO ke kaʻina hana o ka paipu laina API 5L e pili ana i nā ana mana koʻikoʻi e hōʻoia i kona hilinaʻi.Hana ʻia kēia mau paipu i ke kila kalapona a loaʻa iā lākou nā waiwai mechanical maikaʻi loa.ʻO ka mālama pono ʻana i nā kūlana API e hōʻoiaʻiʻo e hiki i kēia mau paipu ke kūpaʻa i nā piʻi kiʻekiʻe a me nā hoʻololi ʻana o ka mahana, e kūpono ana iā lākou no nā noi koʻikoʻi i ka ʻoihana ʻaila a me ke kinoea.
