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.

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 ka manaʻo o C250 ma AS/NZS 1163?
A: ʻO "C" ke kū nei no Cold-formed, a ʻo "250" ke hōʻike nei i ka ikaika hua liʻiliʻi loa o 250 MPa. ʻO kēia ka papa kūkulu pae komo i ka moʻo AS/NZS 1163.
He aha ka ʻokoʻa ma waena o C250 a me C250L0?
A: ʻAʻohe koi hoʻāʻo hopena i koi ʻia ʻo C250, kūpono no ke kūkulu ʻana maʻamau i nā aniau kaulike. Pono ʻo C250L0 i ka hoʻāʻo hopena Charpy ma 0°C (ʻawelike 27J), e kūpono ai no nā noi aniau anuanu.
Q: He aha nā ʻano i loaʻa no AS/NZS 1163 C250?
A: Poepoe (Nā ʻĀpana Hollow Pōʻai - CHS), huinahā (Nā ʻĀpana Hollow Huinahā - SHS), a me ka huinahā (Nā ʻĀpana Hollow Huinahā - RHS). Loaʻa nā kinona ʻekolu ma ka papa C250.
Q: He kūpono anei ʻo C250 no nā noi kūkulu?
ʻAe. He kūpono ʻo C250 no nā noi kūkulu māmā e like me nā mōlina hale, nā pa lima, nā pā, nā scaffolding, a me ka hana maʻamau kahi i lawa ai ka ikaika yield 250 MPa.
Q: Hiki ke hoʻoheheʻe ʻia ʻo C250?
A: ʻAe. Hiki ke hoʻopili maikaʻi ʻia ma muli o ke kalapona haʻahaʻa like (CE max 0.35%). ʻAʻole pono ka hoʻomehana mua ʻana no nā mānoanoa o ka paia maʻamau. E hoʻohana i nā mea hoʻopau ER70S-6 (MIG) a i ʻole E6013/E7018 (SMAW).
Q: He aha ka lōʻihi loa i loaʻa no nā paipu C250?
A: Nā lōʻihi maʻamau: 6m a me 12m. ʻO nā lōʻihi maʻamau a hiki i 18m no nā nui poepoe ma lalo o 168mm. ʻO nā ʻāpana huinahā a me nā ʻāpana huinahā i kaupalena ʻia i 12m.
Q: He aha nā ʻano hoʻopau ʻili i loaʻa?
A: ʻŌlohelohe (e like me ka wili ʻia me ka unahi wili), ʻaila ʻia (māmā ka pale ʻana i ka popo), hoʻomākaukau mua ʻia (mea hoʻomaka hale kūʻai), galvanized i hoʻoluʻu wela ʻia (uhi zinc). No nā hana o waho, paipai ʻia ke galvanized.
Q: Hiki iā ʻoe ke hāʻawi i ka nānā ʻana o nā ʻaoʻao ʻekolu no nā paipu AS/NZS 1163 C250?
A: ʻAe. Loaʻa nā nānā ʻana e SGS, BV, TÜV, ABS, DNV, LR. Hāʻawi ʻia nā palapala hōʻoia 3.2 ma ke noi.
Q: He aha ka manawa alakaʻi maʻamau no nā paipu AS/NZS 1163 C250 ERW?
A: Nā nui waihona: 15-20 mau lā. Nā nui maʻamau: 25-35 mau lā. Hoʻohui ka galvanizing i 10-15 mau lā. ʻO C250 ka papa maʻamau i loaʻa koke.
Q: He aha nā palapala āu e hāʻawi ai no nā hoʻouna paipu C250?
A: Palapala Hoʻāʻo Wili (EN 10204 ʻAno 3.1 a i ʻole 3.2), hōʻike hoʻāʻo tensile, hōʻike dimensional, papa inoa hoʻopili, invoice, bila ukana.
Q: He aha ka ʻokoʻa ma waena o nā paipu kūkulu i hana anu ʻia (AS/NZS 1163) a me nā paipu kūkulu i hoʻopau ʻia me ka wela?
A: Ua hana anu ʻia ʻo AS/NZS 1163 (kaʻina hana ERW) me nā ʻae ʻana o ka dimensional paʻa, ʻoi aku ka maikaʻi o ka hoʻopau ʻana o ka ʻili, a me ke kumukūʻai haʻahaʻa. ʻAʻohe hana wela ma hope. ʻO kēia ke kūlana maʻamau no ka hapa nui o nā noi kūkulu ma Australia a me Aotearoa.
