Nā ʻano hoʻohana ʻana i ka paipu kila: Offshore to irrigation

Nā Kūlana Hoʻohana - Octal Pipe

Mai nā rigs wai hohonu a hiki i nā paipu Arctic, nā mākia wai nui a hiki i nā laina kumu wao nahele, nā ʻāina mahiʻai nui a hiki i nā ala uao - Octal Pipe e hāʻawi i ka -kiʻekiʻe hana kila iwi kuamoʻo no ka honua holoʻokoʻa ikehu, ka wai a me nā mea hana.

E hoʻouna i ka nīnau i kēia manawa

Nā Papa ʻAila a me nā ʻea ma waho

Pono nā rigs wai hohonu, nā ʻaoʻao luna FPSO a me nā ʻaʻahu paʻa i nā paipu e ola mau ana i ka neʻe ʻana o ka nalu mau, ka paʻakai paʻakai a me nā kaomi ma mua o 15,000 psi. Nui -anawaena LSAW X65–X70 me 3LPE a i ʻole FBE + paona paona ka maʻamau o ka ʻoihana ma aneʻi. Hoʻopaʻa paʻa ka hana kinoea -pili i nā laina hoʻokuʻu mai ke Kai ʻĀkau a hiki i Palakila ma mua o -mau paakai.

Nā Laina Kahe a me -Kua

Ma ka hohonu ma mua o 2,500 m, SSAW X60–X70 me 5-layer sintered epoxy a i ʻole ka pulu pulu e hāʻawi i ke koena maikaʻi loa o ke kumu kūʻai, ka maʻalahi a me ka pale ʻino. Hāʻawi like ka hoʻolālā seam helical i ke koʻikoʻi piʻo i ka wā e hoʻokomo ʻia ai ka pahu -lay a i ʻole J-lay, ʻoiai ʻo ka mānoanoa CWC o 50–120 mm e hōʻoiaʻiʻo i ka paʻa i lalo i nā au ikaika.

Ka hoʻouna ʻana i ka mamao -ma uka

Ke hilina'i nei nā laina kumu kinoea -'āina, huahana a me-ea i ka API 5L X52–X80 LSAW no ka uhi 'ana i mau haneli kilomika me nā wahi pauma li'ili'i. 3Ka uhi LPP a me ka pale cathodic e hā'awi i ka 50+ makahiki o ke ola ho'olālā ma nā wao akua, ka hau a me ka aina mahi'ai. E mālama ka mānoanoa o ka pā - i ka mānoanoa o ka pā a no laila ke kaumaha a me ke kumu kū'ai - i ka li'ili'i loa.

ʻAi ʻo Swamp, Marsh & Rainforest Crossings

ʻO nā lepo palupalu a maikaʻi loa ma nā wahi e like me ka Amazon Basin, Niger Delta, a me Louisiana bayous e koi aku i ka uhi paona paona kaumaha (CWC) ma nā paipu SSAW a i ʻole LSAW no ka loaʻa ʻana o ka buoyancy maikaʻi ʻole a pale i ka holo ʻana i ka wā o ke kai. ʻO nā pā mānoanoa i hui pū ʻia me ka fusion -bonded epoxy (FBE) a i ʻole 3LPE coatings e kūʻē pono i ka H₂S, CO₂, a me nā ʻakika kūlohelohe i loaʻa mau i nā kaiapuni wai.

Uena wai a me ka wai o ke kūlanakauhale

Ma lalo o nā alanui o ke kūlanakauhale,ʻO nā paipu wiliwili ʻia ʻo AWWA C200aNā paipu ASTM A53 ERWʻO ia ka mea i koho ʻia no nā kumu wai inu, nā apo pale ahi, a me nā kumu wai ʻino.

Kulokosima -mea paʻaa i ʻolemeaʻai-pili epoxyhoʻokō piha meNSF/ANSI 61no ka inu ʻana-palekana wai, ʻoiai ma wahopolyurethane, polyethylene extruded, a i ʻolepale -pili lipine anti corrosionhāʻawi -palekana no ka wā lōʻihi i ka lepo o ke kūlanakauhale koʻikoʻi, ka wai lepo, a me ka ʻinoʻino -ʻewaewa i loaʻa ma nā wahi nui.

Kawai Kuai a me ka Mahiai

Hoʻohana ʻia ka SSAW (12–48 in) i uhi ʻia i ka SSAW a i ʻole polyethylene -nui{1}}pivot a me drip no ka hoʻoneʻe ʻana i nā miliona mau galani i kēlā me kēia lā me ka ʻaneʻane ʻaʻole leakage. ʻO ka māmā ma ka mika a me ka lōʻihi he 12-18 m ka lōʻihi e hōʻemi i nā hui a me ka manawa hoʻokomo ma waena o ka ʻāina mahiʻai.
