A252 Alakaʻi Piha i ka Paipu Kila Papa 2: Kūpono no nā Papahana Laina ʻAuwai i Hoʻopaʻa ʻia i ka Arc i Hoʻoheheʻe ʻia i ka Pālua

Wehewehe Pōkole:

He mea koʻikoʻi ke koho pono ʻana i nā mea hana no ka hōʻoia ʻana i ka hana pono a me ke ola lōʻihi o kāu ʻōnaehana ʻauwai. Ma waena o nā koho like ʻole i loaʻa, ua ʻike ʻia ka paipu kila A252 GRADE 2 no kona ikaika a me ke kūpaʻa kiʻekiʻe a ua lilo ia i koho kaulana no ke kūkulu ʻana i nā paipu ʻauwai pālua i hoʻopaʻa ʻia i ka arc (DSAW). ʻO ka hoʻohui ʻana i ka ikaika o ka paipu kila A252 GRADE 2 me ka hilinaʻi o ka ʻenehana wili DSAW e hana i nā ʻōnaehana ʻauwai pono. Ma kēia blog, e ʻimi mākou i nā hiʻohiʻona koʻikoʻi, nā pono a me nā noi o ka paipu kila A252 Grade 2 i nā papahana ʻauwai DSAW.

E aʻo e pili ana i ka Paipu Kila Papa 2 A252:

Paipu kila A252 PAPALE 2he paipu kila kalapona i hoʻolālā kūikawā ʻia no ka hoʻohana ʻana i nā paipu kaomi a me nā noi kūkulu. Hana ʻia ia e like me nā kūlana ASTM (American Society for Testing and Materials), e hōʻoiaʻiʻo ana i nā kūlana kiʻekiʻe a me ka pololei o ke ana. Hōʻike ka hoʻolālā GRADE 2 ua hana ʻia ka paipu kila me ka hoʻohana ʻana i ka hoʻoheheʻe arc submerged a i ʻole nā ʻano hoʻoheheʻe seamless.

Ke koʻikoʻi o ka hoʻoheheʻe ʻana i ka arc pālua i lalo o ka wai:

Kuʻihao arc pālua i hoʻokomo ʻia, i ʻike ʻia hoʻi ʻo DSAW, he hana kuʻihao kūikawā loa ia i hoʻohana ʻia e hoʻohui i nā ʻāpana o ka paipu kila A252 GRADE 2. Hāʻawi ʻo DSAW i kekahi mau pono ma luna o nā ʻano kuʻihao ʻē aʻe, me ka pono kuʻihao maikaʻi loa, nā wikiwiki kuʻihao kiʻekiʻe, ka liʻiliʻi o ka hoʻopilikia ʻana, a me ka kaohi maikaʻi loa o ka hoʻokomo wela. Hōʻoiaʻiʻo ia i kahi pilina ikaika ma waena o nā paipu, e hoʻemi ana iā lākou i ka maʻalahi o ka leaka, ka pala a me ka hōʻino ʻana i ke kūkulu ʻana.

No ke aha e hoʻohana ai i ka paipu kila A252 Papa 2 no nā papahana ʻauwai?

1. IKAIKA MAIKAʻI LOA A ME KE KŪPAʻA: Loaʻa i ka paipu kila A252 GRADE 2 ka ikaika tensile kiʻekiʻe, e kūpaʻa ai i nā pilikia a me nā kaomi o waho. ʻO ko lākou kūpaʻa e hōʻoia i ka lōʻihi o ke ola lawelawe, e hōʻemi ana i ka pono no ka hoʻololi pinepine ʻana a i ʻole ka hoʻoponopono ʻana.

2. Ke Kūʻē i ka ʻAi ʻOle: Ua hoʻolālā ʻia ka paipu kila A252 GRADE 2 e kū i nā kūlana ʻino o ka honua, me ka ʻike ʻana i ka wai ʻino, nā kemika a me ka makū, me ka ʻole o ka ʻino a i ʻole ka palaho ʻana. Hoʻonui nui kēia hiʻohiʻona i ke ola lawelawe o nā paipu wai ʻino.

3. Kūʻai kūpono: Hāʻawi ka paipu kila A252 Papa 2 i kahi hopena kūpono no ke kūkulu ʻana i nā paipu ʻauwai. ʻO kā lākou mau koi mālama haʻahaʻa a me ke ola lōʻihi e hiki ke mālama i nā kaona a me nā mea hana papahana i nā mālama kālā nui i ka hala ʻana o ka manawa.

Ka hoʻohana ʻana o ka paipu kila A252 papa 2 i ka ʻenekinia sewer:

Hoʻohana nui ʻia ka paipu kila A252 GRADE 2 i nā ʻano papahana ʻōnaehana hoʻoheheʻe wai like ʻole, e like me:

1. ʻŌnaehana wai ʻino o ke kūlanakauhale: Hoʻohana nui ʻia nā paipu kila A252 Papa 2 i ke kūkulu ʻana i nā paipu wai ʻino o ke kūlanakauhale no ka lawe pono ʻana i ka wai ʻino mai nā wahi noho a me nā wahi kalepa i nā hale hana hoʻomaʻemaʻe.

2. ʻŌnaehana ʻŌpala ʻOihana: Pono nā ʻoihana ʻoihana i nā ʻōnaehana ʻōpala ikaika e lawelawe i ka hoʻokuʻu ʻana o ka wai ʻino mai nā ʻāpana hana a me nā hale hana ʻē aʻe. Hāʻawi ka paipu kila A252 GRADE 2 i ka ikaika a me ke kūpaʻa e pono ai no kēia ʻano noi paipu wai ʻino ʻoihana.

I ka hopena:

I ka wā e hiki mai analaina ʻauwaiʻO ke kūkulu ʻana, ʻo ka paipu kila A252 GRADE 2 i hui pū ʻia me ka ʻenehana wili DSAW e hāʻawi ana i ka ikaika, ka lōʻihi a me ka hana holoʻokoʻa. ʻO kona kūpaʻa kūʻokoʻa i ka pala, ka ikaika tensile kiʻekiʻe a me ke kumukūʻai kūpono e kūpono ai no nā ʻano papahana ʻōnaehana sewer like ʻole. Ma ka hoʻohana ʻana i kēia mau mea holomua a me nā ʻano hana wili, hiki i nā kūlanakauhale ke hoʻonui nui i ke ola a me ka pono o kā lākou mau ʻōnaehana sewer, e hōʻemi i nā kumukūʻai mālama a hōʻoia i kahi kaiapuni maʻemaʻe a olakino hoʻi no nā mea āpau.
