ʻO ka paipu laina i hoʻoheheʻe ʻia i ka Arc Spiral X60 no nā paipu ʻaila

ʻO ka paipu laina i hoʻoheheʻe ʻia i loko o ka wai ʻo X60 Spiral Submerged Arc no nā paipu ʻaila Kiʻi i hōʻike ʻia

Wehewehe Pōkole:

Ke hoʻomau nei ka ulu ʻana o ke koi no ka ʻaila a me ke kinoea kūlohelohe, a me ia e hele mai ai ka pono no nā paipu kūpono a hilinaʻi hoʻi. ʻO kēia kahi e komo ai ka paipu laina X60 SSAW. ʻO kēia ʻano paipu kila wili kahi koho kaulana no ke kūkulu ʻana i nā paipu ʻaila a hāʻawi i nā pono he nui e lilo ai ia i hopena kūpono no ka halihali ʻaila a me ke kinoea.

ʻO ka paipu laina X60 SSAW, i ʻike ʻia hoʻi he paipu paipu welded arc spiral submerged, hoʻohana i nā wili kila i ʻōwili wela ʻia ma ke ʻano he mea maka e kulou ai i ke kaha i loko o nā paipu. ʻO kēia kaʻina hana hana e hana ai i ka paipu ʻaʻole wale i ikaika a paʻa, akā kūpaʻa loa hoʻi i ka pala a me ke kaumaha. He mea koʻikoʻi kēia mau ʻano no kapaipu ʻaila nā laina, kahi i hoʻopilikia pinepine ʻia e nā kūlana kaiapuni paʻakikī a me nā kūlana kaomi kiʻekiʻe.

ʻO kekahi o nā pono nui oX60Paipu laina SSAWʻo kona ikaika kiʻekiʻe. ʻO ka ikaika haʻahaʻa loa o kēia paipu he 60,000 psi, e kūpono ana no nā pono kaomi kiʻekiʻe o ka halihali ʻaila a me ke kinoea. Hōʻoia pū ke kaʻina hana kuʻi wili i ka mānoanoa like o ka paia o ka paipu, kahi e hoʻonui hou ai i kona ikaika a me ka hilinaʻi.

Ma waho aʻe o ka ikaika, ua ʻike ʻia ka paipu laina X60 SSAW no kona ductility maikaʻi loa a me ka paʻakikī o ka hopena. ʻO ke ʻano kēia, hiki i ka paipu ke kū i nā pilikia a me nā ʻūmiʻi o ka lawe ʻana a me ke kau ʻana me ka ʻole o ka hoʻopilikia ʻana i kona kūpaʻa. He mea nui loa kēia no nā laina paipu aila, kahi e pono pinepine ai ke hele i nā ʻāina paʻakikī a lanakila i nā pilikia like ʻole i ka wā o ke kūkulu ʻana.

Eia kekahi, ʻo ka paipu laina X60 SSAW he kūpaʻa loa ia i ka pala, e lilo ia i hopena lōʻihi a kūpono hoʻi no nā laina paipu aila. Hoʻokumu ke kaʻina hana kuʻihao wili i kahi ʻili laumania a me nā kuʻihao kūlike, e hōʻemi ana i ka pilikia o ka pala a hoʻolōʻihi i ke ola o ka paipu. He mea koʻikoʻi kēia no ka aila.paipus, kahi i hōʻike ʻia i nā mea ʻino a me nā mea pili i ke kaiapuni e hiki ai ke hoʻohaʻahaʻa i nā mea maikaʻi ʻole.

I ke kūkulu ʻana i nā paipu aila, he mea nui loa ka palekana a me ka hilinaʻi. Hoʻokō ka paipu laina X60 SSAW i nā kūlana āpau ma aneʻi, e hāʻawi ana i kahi hopena ikaika, paʻa a kū i ka pala e hiki ke kū i nā pilikia o ka lawe ʻana i ka aila a me ke kinoea. ʻO kona ikaika kiʻekiʻe, ka ductility maikaʻi loa a me ka paʻakikī o ka hopena e lilo ia i koho hilinaʻi no nā papahana paipu paʻakikī loa.

I ka hōʻuluʻulu manaʻo, ʻo ka paipu laina X60 SSAW ke koho mua no nā paipu aila ma muli o kona ikaika kiʻekiʻe, ka lōʻihi a me ke kūpaʻa i ka pala. ʻO kāna hana hoʻoheheʻe wili e hana i nā paipu e hiki ke kū i nā kaomi kiʻekiʻe, ka ʻāina paʻakikī a me nā wahi pala, e lilo ia i hopena hilinaʻi a kūpono hoʻi no ka halihali ʻaila a me ke kinoea. I ke kūkulu ʻana i nā paipu aila, ʻo ke koho ʻana i ka paipu paipu wili submerged arc X60 he hoʻoholo ia e hōʻoia i ka palekana a me ka hilinaʻi o ka hana holoʻokoʻa.
