Ma waena o nā "kaʻa" e pono ai e neʻe i kekahi mea, ʻo kekahi o nā mea maʻamau he pipeline.Hāʻawi ka pipeline i nā kumukūʻai haʻahaʻa a me ka hoʻomau mau ʻana o nā kinoea a me nā wai.I kēia lā, nui nā ʻano pipeline.ʻOkoʻa nā hoʻolālā i ka unahi, anawaena, kaomi, a me ka mahana hana.
ʻOkoʻa nā paipu nui, pono-network, ʻenehana, moku (mīkini) i ka unahi.E nānā pono kākou i ke kumu a me nā ʻāpana o ka laina laina nui a me ka ʻenehana.
Pukupaipu.Koho a me ka waeʻano
He ʻano ʻenehana paʻakikī ʻo Trunk pipelines, nona ka fila pipeline multi-kilomita, ke kinoea a i ʻole ka ʻaila pumping stations, nā ala i nā kahawai a i ʻole nā alanui.ʻO nā pipelines e lawe i ka aila a me nā huahana ʻaila, ke kinoea hydrocarbon wai, ke kinoea wahie, ke kinoea hoʻomaka, etc.
Hana ʻia nā paipu nui a pau e ka ʻenehana welding.ʻO ia hoʻi, ma ka ʻili o kekahi paipu nui hiki iā ʻoe ke ʻike i kahi spiral a i ʻole kahi hili pololei.Ma keʻano he mea no ka hanaʻana i ia mau paipu, hoʻohanaʻia ke kila, no ka mea, he mea waiwai, paʻa, hoʻomaʻamaʻa maikaʻi a hilinaʻi.Eia kekahi, hiki iā ia ke "classic" structural steel me nā mea mechanical i koho ʻia, haʻahaʻa-carbon kila a i ʻole carbonic e lilo i mea maʻamau.
Hoʻokaʻawale ʻana i nā paipu laina nui
Ma muli o ke kaomi hana i ka pipeline, ua māhele ʻia nā pipeline gas nui i ʻelua mau papa:
ʻO I - ma ka hana ʻoi aku ma mua o 2.5 a 10.0 MPA (ma luna o 25 a 100 kgs/cm2) i komo;
II - ma ka hana ʻana o ka ʻoi aku ma mua o 1.2 a 2.5 MP (ma luna o 12 a 25 kgs/cm2) i komo.
Ma muli o ke anawaena o ka pipeline ua hoʻokaʻawale ʻia i ʻehā mau papa, mm:
ʻO I - me ke anawaena maʻamau ma mua o 1000 a 1200 i hoʻokomo ʻia;
II - like, ma luna o 500 a 1000 i komo;
III ua like.
IV - 300 a emi mai paha.
Nā paipu ʻenehana.Koho a me ka waeʻano
ʻO nā pipeline ʻenehana nā mea hana no ka hoʻolako ʻana i ka wahie, ka wai, nā mea maka, nā huahana semi-finished a me nā huahana like ʻole i hoʻohana ʻia i ka hana ʻana i kahi mea kanu ʻoihana.ʻO ia mau paipu e lawe i nā mea maka a me nā ʻōpala like ʻole.
Hana ʻia ka hoʻokaʻawale ʻana o nā pipeline ʻenehana i nā ʻano like:
Wahi:i waena o ka manaʻo, intra-branch.
ʻO ke ʻano o ka waiho ʻana:luna-honua, lepo, lalo.
Pumi kūloko:kaomi-ʻole (self-ute), ʻūhā, haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, kaomi waena, kaomi kiʻekiʻe.
Ka wela o ka mea hiki ke lawe ʻia:cryogenic, anu, maʻamau, mahana, wela, wela loa.
ʻO ka huhū o ka mea hiki ke lawe ʻia:ʻaʻole hoʻopaʻapaʻa, nāwaliwali-hoʻopaʻapaʻa (liʻiliʻi liʻiliʻi), waena-hoʻopaʻapaʻa, hoʻopaʻapaʻa.
Mea hiki ke lawe ʻia:paipu mahu,paipu wai, paipu,paipu kinoea, paipu oxygen, paipu aila, uwea acetyleno, paipu aila, paipu kinoea, pipeline acid, paipu alkaline, ammonia pipelines, etc.
Material:ke kila, ke kila me ka uhi o loko a i waho paha, mai nā metala non-ferrous, hao hao, mai nā mea metala ʻole.
Huina:hiki ole ke kaawale, hookui.
