ʻO ka paipu API 5L ERW he mea koʻikoʻi i ka ʻoihana aila a me ke kinoea, ʻike ʻia no kona hilinaʻi a me kāna hana i nā ʻōnaehana pipeline. Ma keʻano he mea hana nui o nā paipu kila ERW a me LSAW, ua kūpaʻa ʻo Longma Group i ka hoʻolako nā paipu API 5L ERW kiʻekiʻe i kūpono i nā kūlana ʻoihana. Ma kēia alakaʻi holoʻokoʻa, e ʻimi mākou i nā kikoʻī koʻikoʻi, nā pae dimensional, nā koi hoʻohui kemika, a me nā helu kaomi.

He aha nā ʻōlelo kikoʻī o ka API 5L ERW Pipe?
ʻO ka paipu API 5L ERW, i ʻike ʻia ʻo Electric Resistance Welded pipe, ua hana ʻia e like me ka American Petroleum Institute (API) 5L kikoʻī. Hōʻike kēia maʻamau i nā koi no nā paipu laina laina ʻole a welded i hoʻohana ʻia i nā ʻōnaehana halihali pipeline i ka ʻoihana ʻaila a me nā ʻoihana kūlohelohe. ʻO nā kikoʻī koʻikoʻi he:
- Mea Papa: Loaʻa nā paipu API 5L ERW ma nā papa like ʻole, me A25, A, B, X42, X46, X52, X56, X60, X65, X70, a me X80. Loaʻa i kēlā me kēia papa i nā pono mechanical a me nā koi hoʻohui kemika.
- Nā Papa Kūlana Huahana: Hoʻokaʻawale ʻia nā paipu API 5L i ʻelua pae kikoʻī huahana (PSL): PSL1 a me PSL2. He koi koʻikoʻi ko PSL2 no ka hoʻohui ʻana i nā kemika, nā waiwai mechanical, a me ka hoʻokolokolo hoʻomake ʻole.
- Ke Kaʻina Hana Hana: Hoʻopuka ʻia nā paipu ERW ma ka hana ʻana i nā wili kila a i ʻole nā palapala i loko o ke ʻano cylindrical a hoʻopaʻa ʻia i ka seam longitudinal me ka hoʻohana ʻana i ka ʻenehana wili uila.
- Hoʻomaʻamaʻa wela: Ma muli o ka papa a me nā koi, API 5L ERW paipu hiki ke hana i nā kaʻina hana wela e like me ka normalizing, quenching, and tempering e hoʻokō i nā waiwai mechanical i makemake ʻia.
- Hoʻopau i ka ʻili: Hiki ke hoʻolako ʻia nā paipu API 5L me nā ʻano like ʻole o ka ʻili, me ka as-welded, pickled a me ka aila, a i ʻole me nā uhi waho/loko no ka pale ʻana i ka corrosion.
Hōʻoia kēia mau kikoʻī i ka hoʻokō ʻana o nā paipu API 5L ERW i nā koi koʻikoʻi o ka ʻoihana aila a me ka ʻenehana, e hāʻawi ana i ka hana hilinaʻi i nā noi koi.
He aha nā ʻāpana o ka API 5L ERW Pipe?
Loaʻa nā paipu API 5L ERW i kahi ākea ākea e kūpono i nā noi pipeline. Loaʻa nā laulima dimensional:
- Anawaena waho (OD): API 5L ERW paipu maʻamau mai 1/2 iniha (12.7 mm) a 24 ʻīniha (609.6 mm). Eia naʻe, ʻo ka nui maʻamau ma waena o 2 iniha (50.8 mm) a me 20 ʻīniha (508 mm).
- ʻO ka mānoanoa o ka pā: ʻokoʻa ka mānoanoa o ka pā ma muli o ka helu kaomi koi a me ka noi. Hiki iā ia ke hele mai 0.109 iniha (2.77 mm) a i 0.750 iniha (19.05 mm) a ʻoi aku paha.
- Ka lōʻihi: ʻO ka lōʻihi maʻamau he 12 mika (39.4 kapuaʻi) a i ʻole 6 mika (19.7 kapuaʻi). Eia naʻe, hiki ke hana ʻia nā lōʻihi maʻamau ma muli o nā koi o ka papahana.
- Hoʻopau Hoʻopau: Hiki ke hoʻolako ʻia nā paipu API 5L ERW me nā wēlau maʻamau, nā wēlau beveled no ka wili ʻana, a i ʻole nā ʻaoʻao wili no nā pili kikoʻī.
He mea nui e hoʻomaopopo he ʻokoʻa paha ka loaʻa ʻana o nā ana kikoʻī ma muli o ka mea hana a me ka pae paipu. Ma Longma Group, hāʻawi mākou i kahi ākea ākea o nā ana paipu API 5L ERW e hoʻokō i nā pono papahana like ʻole.
He aha nā Koina Hoʻohui Kemika no ka API 5L ERW Pipe?
ʻO ka hui kemika o API 5L ERW paipu He mea koʻikoʻi ia i ka hoʻoholo ʻana i kona mau pono mechanical a me kāna hana. Hōʻike ka ʻōlelo kikoʻī API 5L i nā koi kikoʻī no ka haku melemele o nā māka like ʻole. Eia kekahi mau mea koʻikoʻi a me ko lākou mau pae maʻamau:
- Kalapona (C): 0.05% - 0.28% (ma muli o ka papa)
- Manganese (Mn): 0.60% - 1.75% (ma muli o ka papa)
- ʻO Phosphorus (P): 0.030% ka nui (PSL1), 0.025% ka nui (PSL2)
- Sulfur (S): 0.030% ka nui (PSL1), 0.015% ka nui (PSL2)
- Silika (Si): 0.10% - 0.45% (ma muli o ka papa)
- ʻO Vanadium (V), Niobium (Nb), a me Titanium (T): Hiki ke hoʻohui ʻia kēia mau mea no ka hoʻomaikaʻi ʻana i nā waiwai mechanical, me nā palena kikoʻī i wehewehe ʻia no kēlā me kēia papa.
No nā paipu API 5L ERW kiʻekiʻe, hiki ke hoʻokomo ʻia nā mea hoʻohui ʻē aʻe e like me Chromium (Cr), Nickel (Ni), a me Molybdenum (Mo) no ka hoʻomaikaʻi ʻana i ka ikaika a me ka pale ʻana i ka corrosion. ʻOkoʻa nā koi o ka haku mele ma muli o ka pae paipu a me ka pae kikoʻī o ka huahana (PSL1 a i ʻole PSL2).
He mea pono ke hoʻomaopopo ʻia ʻo ka carbon equivalent (CE) kahi mea nui i ka hoʻoholo ʻana i ka weldability o ka paipu. Hāʻawi ka ʻōlelo kikoʻī API 5L i nā ʻōkuhi no ka helu ʻana i ka CE ma muli o ka haku mele, me nā palena kiʻekiʻe i kuhikuhi ʻia no nā māka like ʻole.
He aha nā ʻōlelo hoʻohālikelike a me ka mānoanoa o ka pā?
ʻO nā helu kaomi a me nā kikoʻī mānoanoa o ka pā o ka paipu API 5L ERW he mau mea koʻikoʻi i ka hoʻoholo ʻana i kona kūpono no nā noi pipeline kikoʻī. ʻO kēia mau kikoʻī pili pili loa a hilinaʻi i nā kumu like ʻole, me:
- Papa Paipu: ʻO nā paipu papa kiʻekiʻe (e laʻa, X65, X70) ʻoi aku ka kiʻekiʻe o nā helu kaomi ma muli o ko lākou hoʻonui ʻana i ka ikaika.
- Ka Anawaena Mawaho: Pono nā paipu anawaena nui i nā paia mānoanoa e kū i ke kaomi kūloko like me nā paipu anawaena liʻiliʻi.
- Mea Hoʻolālā: Hoʻohana ʻia kēia kumu palekana no ka helu ʻana i nā kānalua like ʻole a e hōʻoia i ka palena o ka palekana i ka hoʻolālā pipeline.
- Nā Kūlana lawelawe: ʻO ka mahana hana, ka piʻi ʻana o ke kaomi, a me nā ukana waho e hoʻoikaika i ka mānoanoa o ka pā i koi ʻia a me ka helu kaomi.
ʻO ka mānoanoa o ka pā o ka paipu API 5L ERW e kuhikuhi pinepine ʻia me ka hoʻohana ʻana i kekahi o nā ʻano ʻelua:
- Ka Mānoanoa Pā Maʻamau: Hana ʻia nā paipu e like me nā papa hana mānoanoa o ka paia (e laʻa, SCH 40, SCH 80) e pili ana i ka nui o ka paipu.
- ʻO ka mānoanoa o ka pā maʻamau: Hiki ke hana ʻia nā paipu me nā mānoanoa pā kikoʻī i helu ʻia ma muli o ke kaomi hoʻolālā, ke anawaena paipu, a me nā waiwai waiwai.
Hoʻoholo ʻia ka helu kaomi o ka paipu API 5L ERW me ka hoʻohana ʻana i kēia ʻano:
P = (2 * S * t) / (D * F)
Kahi: P = Pīhoihoi hoʻolālā S = ʻO ka ikaika hua liʻiliʻi i koho ʻia t = Ka mānoanoa o ka pā inoa D = Ke anawaena o waho F = Ke kumu hoʻolālā (maʻamau 0.72 no nā paipu aila a me ke kinoea)
He mea nui e hoʻomaopopo he haʻahaʻa paha ka helu kaomi maoli ma mua o ka waiwai i helu ʻia ma muli o nā kumu hou aʻe e like me ka emi ʻana o ka mahana, ka pono hui, a me ka ʻae ʻana i ka corrosion.
Hoʻokaʻaʻike i ka hui Longma
Ma Longma Group, loea mākou i ka hana kiʻekiʻe API 5L ERW paipu i kūpono a ʻoi aku i nā kūlana ʻoihana. ʻO kā mākou laulā piha o nā māka, ka nui, a me ka mānoanoa o ka paia e hōʻoia i hiki iā mākou ke hāʻawi i ka hopena kūpono no kāu papahana pipeline. Me kā mākou mau hale hana hou a me nā kaʻina hana hoʻomalu maikaʻi, hōʻoia mākou i ka hilinaʻi a me ka hana o kā mākou paipu ERW.
Inā ʻoe e ʻimi nei i nā paipu API 5L maikaʻi no kāu papahana aʻe, mai hoʻokaʻulua e kelepona i kā mākou hui loea. Eia mākou e pane i kāu mau nīnau, hāʻawi i ka ʻike kikoʻī huahana, a hāʻawi i nā ʻōlelo hoʻokūkū. E kelepona iā mākou i kēia lā ma info@longma-group.com a ʻike i ka ʻokoʻa o Longma Group i ka kūʻai ʻana i ka paipu. E hana pū kāua e hōʻoia i ka holomua o kāu papahana pipeline!
