9. Hoʻopili a me ka hoʻouna ʻana
Hoʻopili ʻia a hoʻouna ʻia nā paipu ERW me ke akahele loa e hōʻoia i ko lākou palekana i ka wā e lawe ʻia ai. Eia ka wehewehe ʻana o ke kaʻina hana hoʻopili a me ka hoʻouna ʻana:
Pūʻolo:
Uhi Palekana:Ma mua o ka hoʻopili ʻana, hiki ke uhi ʻia nā paipu me kahi papa lahilahi o ka ʻaila anti-rust a i ʻole ka varnish pale e pale aku i ka palaho o ka ʻili a me ka oxidation i ka wā e mālama ai a me ka lawe ʻana. Loaʻa pū ka hoʻopau ʻōlohelohe no ka hoʻopili koke ʻana i ka wahi i hele ʻia ai.
Hoʻopili ʻana:Hoʻopili pono ʻia nā paipu o nā ana like a me nā kikoʻī i loko o nā puʻupuʻu hexagonal a i ʻole rectangular. Hoʻopaʻa ʻia lākou me ka hoʻohana ʻana i nā kaula kila (maʻamau he 3-5 mau kaula no kēlā me kēia puʻupuʻu) e pale ai i ka neʻe ʻana i loko o ka puʻupuʻu.
Nā Pale Hopena:Hoʻokomo ʻia nā pāpale hopena palaki (PE a i ʻole PP) ma nā wēlau ʻelua o kēlā me kēia paipu e pale i nā wēlau beveled, nā wēlau maʻemaʻe, a me nā pilina wili mai ka pōʻino o ka hopena, ke komo ʻana o nā ʻōpala, a me ka makū.
Ka Hoʻopili ʻana a me ka Cushioning:No nā kauoha hoʻokuʻu aku kiʻekiʻe, hiki ke hoʻohana ʻia nā mea hoʻopaʻa e like me nā apo huʻa a i ʻole nā ʻāpana laholio ma waena o nā papa paipu e pale aku ai i ka ʻānai ʻana a me ka hōʻino ʻana o ka uhi ʻana i ka wā e lawelawe ai.
Nā Pahu Lāʻau a i ʻole nā Pahu:No nā paipu paia lahilahi, nā paipu kikoʻī, a i ʻole nā kauoha uhi kiʻekiʻe, hiki ke hoʻopaʻa ʻia nā paipu i loko o nā pahu lāʻau paʻa a i ʻole nā pahu plywood e hāʻawi i ka palekana i hoʻonui ʻia mai nā mana o waho a me ka lawelawe ʻino.
Hoʻouna ʻana:
ʻAno o ka halihali:Hoʻouna ʻia nā paipu ma o nā moku ipu (20 kapuaʻi/40 kapuaʻi), nā mea lawe nui, a i ʻole ka ukana kaʻaahi ma muli o ka wahi e hele ai, ka nui, a me ka wikiwiki. Loaʻa ka ukana ea no nā hoʻouna laʻana a i ʻole nā hoʻouna manawa koʻikoʻi.
Hoʻokomo ʻana i loko o nā ipu:Nā kauoha liʻiliʻi a waena i hoʻouka ʻia i loko o nā pahu hoʻouna maʻamau, e pale ana i ka ukana mai ka wā, ka makū, a me nā mea haumia o waho i ka wā o ka lawe ʻana.
Hoʻouka ʻana i ka moku nui:ʻO nā kauoha nui (ma ke ʻano maʻamau >200 tons) i hoʻouka pololei ʻia i loko o nā mea lawe ukana nui. ʻO nā kaola hāpai a me nā kaola hohola e pale aku i ka hōʻino; e hoʻopaʻa i ka ukana mai ka neʻe ʻana o ke kai a hoʻopaʻa i ka ukana.
Ka Lepili & Palapala:Ua lepili maopopo ʻia kēlā me kēia pūʻolo me ka papa, ke kūlana, nā ana, ka helu wela, a me nā ʻōlelo kuhikuhi lawelawe. ʻO nā palapala piha (bila kūʻai kalepa, papa inoa hoʻopili, bila ukana, Palapala Hoʻomaka, Palapala Hoʻāʻo Hale Wili) i hoʻomākaukau ʻia no ka hoʻomaʻemaʻe maʻalahi ʻana o nā dute.
Hoʻopaʻa Paʻa:Nā puʻupuʻu i hoʻopaʻa ʻia me ke kaula kila, nā ʻeke dunnage, a i ʻole ke kākoʻo lāʻau e pale aku ai i ka neʻe ʻana, ka ʻōwili ʻana, a i ʻole ka hōʻino ʻia i ka wā e lawe ʻia ai.
Ka Hahai & ʻInikua:Hāʻawi ʻia nā helu hahai ipu no ka nānā ʻana i ka manawa maoli. Loaʻa ka ʻinikua ukana moana (All Risk a i ʻole Me ka Average) ma ke noi.
I ka hōʻuluʻulu manaʻo, hōʻoia ʻo Womic Steel ua hoʻopili ʻia nā paipu ERW Steel āpau me nā hana pale alakaʻi ʻoihana a hoʻouna ʻia me ka hoʻohana ʻana i nā ʻano halihali hilinaʻi e hiki ai i ko lākou wahi i ke kūlana maikaʻi loa. He mea nui nā kaʻina hana hoʻopili a me ka hoʻouna kūpono no ka mālama ʻana i ka pono a me ka maikaʻi o nā huahana i hāʻawi ʻia.
10. Nā Pōmaikaʻi a me nā FAQ o Womic Steel
No ke aha e hui pū ai me Womic Steel?
Hale Kūʻai Hoʻokahi:ʻO ka laulā piha mai nā paipu API 5L ERW a hiki i nā mea hoʻopili paipu OEM e kūlike ana (Elbows, Tees, Reducers, Flanges, Caps) ma nā papa mea kūpono, me ke kila kalapona, ke kila alloy, a me ke kila kila.
Hoʻokō ʻenehana:Nā Palapala Hōʻoia Hoʻāʻo Wili Piha (EN 10204 ʻAno 2.2, 3.1, a i ʻole 3.2) i hāʻawi ʻia me kēlā me kēia ukana, e hōʻike kikoʻī ana i ka haku mele kemika pololei, nā hopena hoʻāʻo mīkini, a me nā hōʻike hoʻokolokolo ʻaʻole luku.
Nā lawelawe waiwai i hoʻohui ʻia:Loaʻa ka beveling hopena (30°-35°), ke kaula ʻana a me ka hoʻopili ʻana, ke kau ʻana i nā pāpale plastik, a me ka uhi anti-corrosion (FBE, 3LPE, 3LPP, Epoxy, Galvanizing) i loko o ka hale a i ʻole ma o nā hale hana hoa kūpono.
Hoʻokūkū Logistics:ʻO ka hui pū ʻana me nā mea hoʻouna ukana honua e hōʻoiaʻiʻo ana i ka hoʻouka ʻana o nā ipu i hoʻonui ʻia (e hoʻonui ana i ka nui no kēlā me kēia ipu) a me ka hoʻouna ʻana ma ka honua holoʻokoʻa me ke kumukūʻai kūpono me nā manawa transit hilinaʻi.
Waihona a me ka Loaʻa:ʻO ka waihona nui o nā nui API 5L X52 maʻamau (2"-24" OD, Papa Kuhikuhi 10-80) e hōʻoiaʻiʻo ana i nā manawa alakaʻi pōkole a me ka pane wikiwiki i nā koi papahana wikiwiki. Hana ʻia nā nui maʻamau ma ke noi me ka manawa alakaʻi maʻamau o 30-45 mau lā.
Ka Mana Hana ʻAwaʻawa:Ka hiki piha e hoʻolako i nā paipu PSL2 me ka hoʻāʻo HIC a me SSC e like me nā kūlana NACE no nā noi kinoea ʻawaʻawa. Paʻakikī i kāohi ʻia i ≤ 248 HV10 / ≤ 22 HRC.
E koho iā Womic Steel Group ma ke ʻano he hoa hilinaʻi no nā Paipu Kila API 5L X52 ERW kiʻekiʻe a me ka hana hoʻouna lanakila ʻole. Welina mai e nīnau!

Nā Nīnau i Nīnau Pinepine ʻia (FAQ)
Q: He aha ke ʻano o ka S235JRH?
A: "S" = kila kūkulu, "235" = ikaika hua liʻiliʻi loa 235 MPa, "JR" = hoʻāʻo hopena mahana lumi (27J ma 20°C), "H" = ʻāpana hakahaka (i hana anu ʻia). ʻO ka helu kila he 1.0039.
He aha ka ʻokoʻa ma waena o S235JRH a me S275JRH?
A: ʻOi aku ka ikaika o ka S275JRH (275 MPa vs 235 MPa) a ʻoi aku ka nui o ke kalapona. ʻOi aku ka hoʻokele waiwai o S235JRH no nā noi ukana māmā a waena. ʻO S275JRH no nā koi ukana kaulike.
Q: He aha nā ʻano i loaʻa no EN 10219 S235JRH?
A: Poepoe (nā ʻāpana hakahaka poepoe - CHS), huinahā (nā ʻāpana hakahaka huinahā - SHS), a me ka huinahā (nā ʻāpana hakahaka huinahā - RHS). Poepoe OD: 21.3-610mm. Huinahā: 25x25 a i 500x500mm. Huinahā: 40x20 a i 600x400mm.
Q: He aha ka ʻokoʻa ma waena o EN 10219 a me EN 10210?
A: Hoʻokumu anu ʻia ʻo EN 10219 (kaʻina hana ERW) me nā ʻae ʻana o ka dimensional paʻa a me ka hoʻopau ʻili maikaʻi. Hoʻopau wela ʻia ʻo EN 10210 me nā koʻikoʻi koena haʻahaʻa. ʻOi aku ka maikaʻi o ke kumukūʻai o EN 10219 no ke kūkulu ʻana maʻamau.
Q: Hiki ke hoʻopili ʻia ʻo S235JRH?
A: ʻAe. Hiki ke hoʻopili maikaʻi ʻia ma muli o ke kūlike kalapona haʻahaʻa (CEV). ʻAʻole pono ka hoʻomehana mua ʻana no ka mānoanoa o ka paia ma lalo o 20mm ma lalo o nā kūlana maʻamau. Nā mea hoʻopau i manaʻo ʻia: ER70S-6 (MIG) a i ʻole E7018 (SMAW).
Q: He aha ka lōʻihi loa i loaʻa?
A: Nā lōʻihi maʻamau: 6m a me 12m. ʻO nā lōʻihi maʻamau a hiki i 18m no nā anawaena ma lalo o 168mm. ʻO nā ʻāpana huinahā a me nā ʻāpana huinahā i kaupalena ʻia i 12m. Loaʻa nā lōʻihi lōʻihi ma ke noi.
Q: He aha nā ʻano hoʻopau ʻili i loaʻa?
A: ʻŌlohelohe (e like me ka wili ʻia me ka unahi wili), ʻaila ʻia (uhi māmā anti-rust), ʻeleʻele i uhi ʻia (lacquer), primed (home primer), galvanized wela (uhi zinc), a pena ʻia paha. He mea maʻamau ka galvanizing e like me EN ISO 1461 no nā noi waho.
Q: Hiki iā ʻoe ke hāʻawi i ka nānā ʻana o ka ʻaoʻao ʻekolu?
A: ʻAe. Hoʻomaʻamaʻa mākou i nā nānā ʻana e DNV, BV, SGS, TÜV, ABS, LR i ka wā hana a ma mua o ka hoʻouna ʻana. 3.2 nā palapala hōʻoia nānā i hāʻawi ʻia ma ke noi.
Q: He aha ka manawa alakaʻi maʻamau?
A: Nā nui waihona: 15-25 mau lā. Nā nui maʻamau: 30-45 mau lā. Hoʻohui ʻo Galvanizing i 10-15 mau lā. Loaʻa nā kauoha wikiwiki (10-15 mau lā) no nā nui liʻiliʻi.
Q: He aha nā palapala āu e hāʻawi ai?
A: Palapala Hoʻāʻo Wili (EN 10204 ʻAno 3.1), hōʻike ana, papa inoa hoʻopili, bila, palapala hoʻoili ukana. Ka māka CE a me ka Hōʻike o ka Hana (DoP) no ka mākeke ʻEulopa.
