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 ka ʻokoʻa ma waena o ASTM A178 GR.A, GR.C, a me GR.D?

A: Loaʻa iā GR.A ka haʻahaʻa loa o ke kalapona (0.10% max) a me ka ikaika (330 MPa tensile) - ʻo ke ʻano hana maikaʻi loa no ke kulou ʻana. ʻOi aku ke kiʻekiʻe o ke kalapona (0.18% max) a me ka ikaika (415 MPa) iā GR.C - ʻo ka mea maʻamau ka hoʻohana ʻia. Loaʻa iā GR.D ke kalapona kiʻekiʻe loa (0.27% max) a me ka ikaika (415 MPa me ka hua kiʻekiʻe) - no nā noi kaomi kiʻekiʻe.

Q: He aha ka ʻokoʻa ma waena o nā paipu paila ASTM A178 (welded) a me ASTM A179 (seamless)?

A: Ua hoʻopaʻa ʻia ʻo A178 me ke kūpaʻa uila (ERW) - ʻoi aku ka maikaʻi o ke kumukūʻai, kūpono no ka hapa nui o nā noi paila. Ua huki anu ʻia ʻo A179 - no ke kaomi kiʻekiʻe a i ʻole kahi i ʻae ʻole ʻia ai ke kuʻi hoʻopaʻa. He mea maʻamau nā mea ʻelua i ka lawelawe paila a me ka mea hoʻololi wela.

Q: He aha nā hoʻokolohua e pono ai no nā paipu paila ASTM A178?

A: Hoʻāʻo hydrostatic (kēlā me kēia paipu), hoʻāʻo pālahalaha, hoʻāʻo flaring, a me ka hoʻāʻo tension transverse a longitudinal paha. Hiki ke kuhikuhi ʻia ʻo NDT (UT a i ʻole ET) e ka mea kūʻai aku. Hana ʻo Womic Steel i nā hoʻāʻo āpau i koi ʻia e like me ASTM A178.

Q: Hiki ke hoʻohana ʻia ʻo A178 GR.A no nā ʻōmole superheater?

A: ʻAe, akā ua kaupalena ʻia i nā mahana kaulike. No ka lawelawe superheater wela kiʻekiʻe, ua ʻōlelo ʻia ʻo GR.C a i ʻole GR.D. ʻO GR.A ka mea maikaʻi loa no ka paia wai paila mahana haʻahaʻa a me nā paipu economizer.

Q: He aha ka mahana hana kiʻekiʻe loa no A178 GR.A?

A: ʻO ka maʻamau a hiki i ka 400°C (750°F) no ka lawelawe mau. No nā mahana kiʻekiʻe aʻe, e noʻonoʻo i nā papa GR.C a i ʻole nā ​​​​​​papa alloy e like me A213 T11 a i ʻole T22. E nānā i ke code hoʻolālā no nā palena mahana kikoʻī.

Q: He aha ka hoʻāʻo flaring a no ke aha he mea nui?

A: Hoʻonui ka hoʻāʻo flaring i ka hopena o ka paipu me ka hoʻohana ʻana i kahi mandrel tapered i kahi pakeneka i kuhikuhi ʻia (maʻamau 15-30%). Hōʻoia ia i ka ductility a me ke kūpaʻa o ka paipu, e hōʻoia ana ʻaʻohe haki i ka wā o ke kau ʻana i ka hoʻonui ʻana o ka paipu paila.

Q: Hiki iā ʻoe ke hāʻawi i ka nānā ʻana o nā ʻaoʻao ʻekolu no nā paipu A178 GR.A?

A: ʻAe. Loaʻa nā nānā ʻana e SGS, BV, TÜV, ABS, DNV, LR. Hāʻawi ʻia nā palapala hōʻoia 3.2 ma ke noi. Loaʻa ka hōʻike ʻana i ka hoʻāʻo hydrostatic, ka hoʻāʻo flaring, a me ka hoʻāʻo flattening.

Q: He aha ka manawa alakaʻi maʻamau no nā paipu ASTM A178 GR.A?

A: Nā nui waihona: 15-25 mau lā. Nā nui maʻamau: 30-45 mau lā. Hoʻohui ka nānā ʻana o ke kolu i 5-10 mau lā. Loaʻa nā kauoha wikiwiki no nā nui liʻiliʻi.

Q: He aha nā palapala āu e hāʻawi ai?

A: Palapala Hoʻāʻo Wili (EN 10204 ʻAno 3.1), hōʻike hoʻāʻo hydrostatic, hōʻike hoʻāʻo flaring/flattening, hōʻike dimensional, papa inoa hoʻopili, invoice, bila ukana.
