Nūhou - Ke hoʻomaopopo nei i ka ʻokoʻa ma waena o nā paipu kila ERW, SSAW, a me DSAW

He kuleana koʻikoʻi ko nā paipu kila i ke kahua o ke kaiāulu o kēia wā, mai nā paipu ʻaila a me ke kinoea a hiki i ka lawe ʻana i ka wai a me nā noi kūkulu. I waena o lākou, ʻo ka mea kaulana loa ʻo ia kaPaipu i hoʻopaʻa ʻia ʻo ERW, Paipu kila SSAW, Paipu kila DSAWʻO ka ʻike i nā ʻokoʻa ma waena o kēia mau huahana e hiki ai i nā ʻenekinia, nā mea hana hana a me nā mea kūʻai ke koho i ka paipu maikaʻi loa no kā lākou noi.

Nā Paipu Kila ASTM A671 CC65 CL 12 EFW no nā Hana ʻOihana a me nā Hana Kūkulu (1)

He aha ka ERW Steel Pipe?

Paipu kila ERWʻO ia hoʻi, pili ia i kahi paipu kila i kūkulu ʻia me ka hoʻohana ʻana i ka wili uila. ʻO ka hopena kēia i ka hoʻokumu ʻia ʻana o kahi humuhumu lōʻihi ma ka lōʻihi o ka paipu.

Eia kekahi o nā hiʻohiʻona koʻikoʻi o nā paipu ERW:
AnawaenaLiʻiliʻi a waena (maʻamau 10 mm - 508 mm).
Mānoanoa o ka paiaLahilahi a waena (mānoanoa maʻamau ≤20 mm).
Nā noiNo nā paipu wai, nā paipu kinoea, a me nā ʻāpana kūkulu a me nā ʻāpana mechanical.
Nā Pōmaikaʻi: Pololei kiʻekiʻe o ke ana, ʻili laumania o loko, hoʻokele waiwai.
PalenaʻAʻole pili no ka lawelawe kaomi kiʻekiʻe loa.

He aha ka paipu kila SSAW?

SSAW (Spiral Submerged Arc Welded)paipu kila, i kapa ʻia hoʻi ʻo HSAW, ua hana ʻia ma ka ʻōwili ʻana i kahi ʻāpana kila i loko o ke ʻano ʻōwili a me ka hoʻopili ʻana i ke humuhumu me ka hoʻohana ʻana i ka hoʻopili ʻana i lalo o ka wai.

Nā hiʻohiʻona koʻikoʻi o nā paipu SSAW:
Anawaena: Waena a nui loa (400 mm–3600 mm+).
Mānoanoa o ka paiaLahilahi a waena (≤25 mm maʻamau).
Humuhumu: Huina wili ma ke kihi i ke koʻi o ka paipu.
Nā noi: Nā paipu ʻaila a me ke kinoea, ka halihali wai, nā papahana kūkulu nui.
Nā Pōmaikaʻi: Hiki ke hana i nā anawaena nui a me ka mānoanoa o ka paia maʻalahi.
Nā PalenaHoʻemi iki ka humuhumu wili i ka ikaika o ke kaomi i hoʻohālikelike ʻia me nā paipu DSAW lōʻihi.

He aha ka DSAW Steel Pipe?

Paipu kila DSAW (Hoʻopaʻa ʻia ʻo Double Submerged Arc)ua like ia mePaipu LSAW (Longitudinal Submerged Arc Welded)i hana ʻia ma ke kulou ʻana i ka papa kila ~1/2 ʻīniha a 3 ʻīniha ka mānoanoa i loko o kahi paukū a hoʻopili ʻia i nā humuhumu o loko a me waho me ka hoʻohana ʻana i kahi kaʻina hana kuʻi arc i lalo.

Nā hiʻohiʻona nui o ka paipu DSAW:
Anawaena: Waena a nui (300–2500 mm maʻamau).
Mānoanoa o ka pāMānoanoa waena a i ʻole (≥6 mm a i 50 mm+).
HoʻohanaNā paipu aila a me ke kinoea kiʻekiʻe a me nā paipu kai, nā noi kūkulu e pono ai ka ikaika kiʻekiʻe.
Nā PōmaikaʻiHe ikaika a hilinaʻi hoʻi nā humuhumu, e kūpono ai ka mea no nā kūlana koʻikoʻi.
Nā hemahemaʻO ka hana ʻana he pipiʻi a me ke kaʻina hana lohi i ka hoʻohālikelike ʻia me ERW a me SSAW.

Hui kila aliʻi Kinahe mea hana ʻoihana ʻo ia no nā huahana paipu kila me nā paipu kila ERW (Electric Resistance Welded), SSAW (Spiral Submerged Arc Welded) a me DSAW (Double Submerged Arc Welded) a me nā mea ʻē aʻe. Ma muli o nā makahiki o ka ʻike ʻoihana, hāʻawi ka ʻoihana i nā kūkākūkā loea piha a me nā ʻōlelo aʻoaʻo no ke ʻano paipu kūpono loa no ka hoʻohana ʻana maka hoʻoili ʻaila a me ke kinoea, ka hoʻoili wai, nā hana ʻoihana kaomi kiʻekiʻe, a me nā papahana vascular, ma waena o nā noi ʻē aʻe.

Ua noʻonoʻo ka Royal Steel Group i nā kumu like ʻole e like meka nui o ka paipu, ka mānoanoa o ka paia, ka papa mea, ka papa kaomi, ke kūpaʻa i ka pala, a me nā kūlana o ke kaiapunie ʻike i nā hopena kūpono loa. Eia kekahi, hāʻawi ʻo China Royal Steel Group i ka lawelawe hana i hana kūikawā ʻia a me ka lawelawe uhi ʻana (ʻo ia hoʻi ka anti-corrosion, galvanization, epoxy lining) a me ka hōʻoia maikaʻi koʻikoʻi me nā kūlana honua o ASTM, ISO a me API.

Ma o ka hana ʻana i nā mea kiʻekiʻe, ka hoʻāʻo pololei a me ke kākoʻo logistics, hiki i ka ʻoihana ke hoʻolako i nā huahana paipu kila e kūlike ana me nā kūlana palekana paʻa, ka lōʻihi a me ka hana, a ma ka huli ʻana e hiki ai i nā mea kūʻai aku ke hāʻawi i nā hoʻonā ʻōnaehana kūpono, hoʻomau, a me ka maikaʻi.

ʻO ke koho ʻana i ka paipu kila kūpono e pili ana i nā koi o ka papahana, ke anawaena, ka mānoanoa o ka paia, a me ka helu kaomi:

Nā paipu ERW: Kūʻai kūpono, kūpono no nā anawaena liʻiliʻi a waena a me nā noi kaomi haʻahaʻa a waena.

Nā paipu SSAWKūpono no nā paipu anawaena nui me ka mānoanoa o ka paia maʻalahi.

Nā paipu DSAWʻO ke koho maikaʻi loa no nā noi kaomi kiʻekiʻe, ikaika kiʻekiʻe e like me nā paipu kai a i ʻole nā paipu aila a me ke kinoea.

ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o nā paipu kila ERW, SSAW, a me DSAW e hōʻoiaʻiʻo ana i ka hana kūpono loa, ka palekana, a me ka hoʻohana pono ʻana i ke kumukūʻai no kekahi papahana ʻoihana.
