Hana ʻana i ka paipu API LSAWkaʻina hana
Paipu wili ʻia i loko o ka wai i hoʻopaʻa ʻia i loko o ka ʻākuhi lōʻihi (Paipu LSAW), i ʻike ʻia hoʻi ʻo ka paipu SAWL. Lawe ia i ka papa kila ma ke ʻano he mea maka, kahi i hoʻohālikelike ʻia e ka mīkini hana, a laila hana ʻia ka wili ʻana i ka arc submerged ma nā ʻaoʻao ʻelua. Ma o kēia kaʻina hana, e loaʻa i ka paipu kila longitudinal submerged welded arc maikaʻi loa, ka paʻakikī o ka wili ʻana, ke ʻano like, ka plasticity a me ka hana sila maikaʻi.
ʻO ke anawaena a me nā waiwai o ka paipu kila welded submerged longitudinal
ʻOi aku ka nui o ke anawaena o ka paipu hoʻoheheʻe arc longitudinal submerged ma mua o ke kuʻi ʻana i ke kū'ē, maʻamau mai 16 ʻīniha a 60 ʻīniha, 406mm a 1500 mm. Loaʻa iā ia ke kūpaʻa kiʻekiʻe maikaʻi a me ke kūpaʻa haʻahaʻa haʻahaʻa.
ʻO Jindalai he mau paipu LSAW no ke kūʻai aku.
Hoʻohana ʻia oLSAW paipu
Ua hoʻohana nui ʻia ia i nā paipu aila a me ke kinoea, ʻoiai nā paipu me ke anawaena nui, ka paia mānoanoa, ka ikaika kiʻekiʻe a me ka mamao lōʻihi. I ka manawa like, e like me ke kikoʻī API, hoʻohana kūikawā ʻia ka paipu LSAW (paipu SAWL a i ʻole ka paipu JCOE) no ka halihali aila a me ke kinoea nui, a kūpono ia no nā paipu e hele ana ma waena o nā kūlanakauhale, nā moana a me nā wahi kūlanakauhale. ʻO kēia ka pae 1 a me ka pae 2.
ʻenehana hana ʻana o ka paipu SSAW (paipu HSAW)
ʻO ka Paipu SSAW, i ʻike ʻia hoʻi ʻo HSAW PIPE, he laina wiliwili kona. Hoʻohana ia i ka ʻenehana wiliwili like me ka wiliwili arc submerged longitudinal. ʻO ka ʻokoʻa, ua wiliwili ʻia nā paipu SSAW, ʻoiai ua wiliwili ʻia nā paipu LSAW. ʻO ke kaʻina hana ʻana, ʻo ia ke ʻōwili i ke kaula kila, i hana ai ke kuhikuhi wiliwili i kahi kihi me ke kuhikuhi o ke kikowaena o ka pipeline, a ua hana ʻia a wiliwili ʻia, no laila he wiliwili ka wiliwili.
ʻO ka laulā nui a me nā ʻano o ka paipu SSAW (paipu HSAW)
ʻO ke anawaena o nā paipu SSAW mai 20 ʻīniha a 100 ʻīniha, a me 406 mm a 2540 mm. ʻO kona pono, hiki iā mākou ke loaʻa nā paipu SSAW me nā anawaena like ʻole ma ka ʻāpana kila like ka nui, kahi i hoʻohana nui ʻia i ka ʻāpana kila maka, a pono e pale ʻia ke kaumaha mua i ka weld, kahi i loaʻa ka hana hoʻokaumaha maikaʻi.
ʻO ka hemahema, ʻaʻole maikaʻi ka nui o ke kino, a ʻoi aku ka lōʻihi o ka weld ma mua o ka lōʻihi o ka paipu, kahi mea maʻalahi ke hana i nā māwae, nā pores, ka hoʻokomo ʻana o ka slag, ka welding kūloko, ka ikaika welding ma lalo o ke kaomi a me nā hemahema ʻē aʻe.
Ka hoʻohana ʻana o SSAWPAIPAU
No ka ʻōnaehana paipu aila a me ke kinoea, akā ma ke code hoʻolālā petroleum, hiki ke hoʻohana ʻia ka paipu SSAW / paipu HSAW ma nā wahi Papa 3 a me Papa 4 wale nō. ʻO ke kūkulu hale, ka halihali wai a me ka mālama ʻana i ka wai ʻino, ka ʻoihana wela, ke kuhikuhipuʻuone, a pēlā aku.
ʻOi aku ka maikaʻi o ka hana o ka paipu LSAW ma mua o ka paipu SSAW.
E like me ka mea i ʻōlelo ʻia ma luna, ua wehewehe nā kikoʻī o nā paipu SAW ʻelua e hoʻohana ʻia nā paipu SSAW ma nā kahua koʻikoʻi ʻole. I kēia manawa, kūʻē ʻo ʻAmelika Hui Pū ʻIa, Iapana a me Kelemānia i nā paipu SSAW, a ʻaʻohe manaʻo e hoʻohana i nā paipu SSAW i nā paipu koʻikoʻi. Hoʻohana kekahi mau paipu i ka paipu SSAW. He kakaikahi nā paipu ma SSAW ma Rusia, a ua hoʻokumu lākou i nā huaʻōlelo hoʻokō koʻikoʻi. No Kina, ma muli o nā kumu mōʻaukala, hoʻohana mau ka hapa nui o nā paipu koʻikoʻi ma Kina i nā paipu SSAW.
Hoʻohālikelike ʻia me nā paipu humuhumu ʻole a me nā paipu ERW. Hoʻohana nui ʻia nā paipu ERW a me SAW no ka lawe ʻana i ka ʻaila a me ke kinoea. Hoʻohana nui ʻia nā paipu kila humuhumu ʻole no ka ʻeli ʻana a me ka ʻimi ʻana i ka ʻaila a me ke kinoea.
Inā ʻoe e noʻonoʻo neike kūʻai ʻana i ka paipu SSAW A I ʻOLE ka paipu LSAW, e ʻike i nā kohoʻO Jindalaiua loaʻa nāu a e noʻonoʻo e hoʻokaʻaʻike aku i kā mākou hui no ka ʻike hou aku. E hāʻawi mākou iā ʻoe i ka hopena maikaʻi loa no kāu papahana.e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou:
