Nā wahi noi maʻamau
Mahalo i kāna hana holoʻokoʻa maikaʻi loa, hoʻohana nui ʻia nā paipu kila kila 20 seamless ma nā kahua aʻe:
ʻAila a me ke kinoea: nā paipu hoʻoili ʻaila a me ke kinoea, ka ʻeli ʻana i ke kaomi kiʻekiʻe
ʻOihana mana: nā paipu paila, nā superheaters, nā economizers
ʻOihana kemika: nā kīʻaha kaomi, nā paipu kemika
Kūkulu a me nā mīkini: nā hale kūkulu, nā ʻāpana mīkini, nā paukū hydraulic
4. Ke kākoʻo ʻana i ka ʻōnaehana maʻamau
Hāʻawi ʻo sanonpipe i nā huahana e like me ka ʻōnaehana maʻamau GOST piha, e hōʻoiaʻiʻo ana i ka hoʻokō piha ʻana me nā koi komo mākeke Lūkini:
| Kūlana Maʻamau | Kūlana |
|---|---|
| GOST 8732-78 | Nā kikoʻī ana (OD, mānoanoa o ka paia, ka lōʻihi) |
| GOST 8731-74 | Nā kūlana loea (ka hoʻohuihui kemika, nā waiwai mechanical, nā lula nānā) |
| GOST 9567-75 | Nā kikoʻī ana no nā paipu kila pololei kiʻekiʻe (i ka wā e pono ai nā ʻae ʻana paʻa) |
Hōʻoiaʻiʻo maikaʻi:
Hāʻawi ʻia kēlā me kēia pūʻulu me kahi MTC piha (Material Test Certificate)
Loaʻa nā palapala hōʻoia EN 10204 3.1/3.2 ma ke noi ʻana
Kākoʻo ʻia nā nānā ʻana o nā ʻaoʻao ʻekolu e SGS, BV, TÜV etc.
5. No ke aha e koho ai i ka sanonpipe?
| Ko mākou mau pono | Nā kikoʻī |
|---|---|
| ʻIke loea maʻamau | Ka hoʻomaopopo hohonu ʻana i ka ʻōnaehana GOST - ka wehewehe pololei ʻana i nā koi loea Lūkini |
| Palapala hōʻoia waiwai | Ke kila 20 i kūlike piha me GOST 8731‑74, like me ASTM A106 Gr.B |
| Hoʻouna wikiwiki | Ke hilinaʻi nei ma luna o 20,000 tone o ka waihona maʻamau, hāʻawi ʻia nā kauoha wikiwiki i loko o 7-15 mau lā |
| Pūʻolo lawelawe piha | Mai ka nīnau ʻana, nā nānā ʻana i ka moʻolelo a me nā ʻōlelo kūʻai i nā palapala a me nā logistics - hoʻouna hoʻokahi |
| Kūpaʻa pilikia ʻole | 240+ mau wahi nānā mana kūloko, ʻaʻohe ʻokoʻa ma nā palapala |
| ʻŌmaʻomaʻo a me ke kalapona haʻahaʻa | Loaʻa nā hōʻike kapuaʻi kalapona huahana e kākoʻo i ka hoʻokō ʻana i ka ESG |
Laʻana o ka wehewehe kikoʻī maʻamau:
* Труба стальная бесшовная горячедеформированная 114×6 ГОСТ 8732-78 / В 20 ГОСТ 8731-74*
(Paipu kila wili ʻole i ʻōwili wela ʻia 114 × 6, e kūlike ana me ke kūlana ana GOST 8732‑78, mea kila 20, e kūlike ana me nā kūlana loea GOST 8731‑74)
6. Kāhea iā mākou
Ua kūpaʻa ʻo sanonpipe i ka hāʻawi ʻana i nā huahana paipu kila seamless GOST-standard kiʻekiʻe i nā mea kūʻai aku ma Rusia a me nā mākeke CIS. Inā makemake ʻoe i nā kikoʻī maʻamau a i ʻole nā nui maʻamau, hāʻawi mākou i ke kākoʻo loea ʻoihana a me nā hoʻonā hoʻolako maʻalahi.
