Sipesifikesonu iṣelọpọ:

Lode opin ti irin pipe 20-426

Irin paipu odi sisanra ti 20-426

Ifihan ọja:

Fun apẹẹrẹ, 40Cr.(Akoonu erogba ti paipu irin alloy 35CrMo jẹ 0.32 ~ 0.40, silikoni 0.17 ~ 0.37, manganese 0.40 ~ 0.70, molybdenum 0.15 ~ 0.25, chromium 0.80 ~ 1.10)

② Awọn eroja alloying akọkọ ni irin, ayafi diẹ ninu awọn eroja microalloying, ni gbogbogbo ti ṣafihan nipasẹ ọpọlọpọ ogorun.Nigbati akoonu alloy apapọ ba kere ju 1.5%, aami ano nikan ni a samisi ni nọmba irin, ṣugbọn kii ṣe akoonu naa.Sibẹsibẹ, ni awọn ọran pataki, o rọrun lati daamu, nọmba “1 ″ le jẹ samisi lẹhin aami ano, gẹgẹbi nọmba irin “12CrMoV” ati “12Cr1MoV”, akoonu chromium ti iṣaaju jẹ 0.4-0.6%, ati pe ti igbehin jẹ 0.9-1.2%.Gbogbo ohun miiran jẹ kanna.Nigbati akoonu ipin alloying apapọ ≥1.5%, ≥2.5%, ≥3.5%……”, aami ano yẹ ki o samisi lẹhin akoonu, o le ṣafihan bi 2, 3, 4……….Fun apẹẹrẹ, 18Cr2Ni4WA.

③ Alloy eroja bi vanadium V, titanium Ti, aluminiomu AL, boron B ati toje aiye RE ni irin wa si microalloying eroja.Botilẹjẹpe akoonu naa kere pupọ, wọn yẹ ki o tun samisi lori nọmba irin.Fun apẹẹrẹ, ni irin 20MnVB.Vanadium jẹ 0.07-0.12% ati boron jẹ 0.001-0.005%.

④ "A" yẹ ki o fi kun ni opin nọmba irin ti irin-giga ti o ga julọ lati ṣe iyatọ rẹ lati gbogboogbo ti o ga didara.

⑤ Idi pataki alloy irin igbekalẹ, irin nọmba ìpele (tabi suffix) duro fun idi ti aami irin.Fun apẹẹrẹ, irin 30CrMnSi ti a lo ni pataki fun awọn skru riveting jẹ afihan bi ML30CrMnSi.

Alloy tube ati tube ailopin mejeeji ni awọn ibatan ati awọn iyatọ, ko le dapo.

Paipu alloy jẹ paipu irin ni ibamu pẹlu ohun elo iṣelọpọ (iyẹn, ohun elo) lati ṣalaye, bi orukọ ṣe daba jẹ paipu alloy;Ati pipe paipu jẹ paipu irin ni ibamu pẹlu ilana iṣelọpọ (ailopin) lati ṣalaye, yatọ si paipu ti ko ni idọti jẹ paipu welded, pẹlu paipu ti o taara welded paipu ati paipu ajija.

Imọ-ẹrọ iṣelọpọ:

1. Yiyi gbigbona (extrusion seamless, steel pipe): òfo tube tube → alapapo → perforating → sẹsẹ diagonal mẹta-giga, lilọsiwaju sẹsẹ tabi extrusion → idinku → iwọn (tabi idinku) → itutu → taara → idanwo hydrostatic (tabi ayewo) → isamisi → ibi ipamọ

2. Tutu kale (yiyi) paipu irin ti ko ni oju: tube tube ofo → alapapo → perforation → akọle → annealing → pickling → oiling (para plating) → olona-kọja tutu iyaworan (yiyi tutu) → tube òfo → itọju ooru → taara → idanwo hydrostatic (ayẹwo) → isamisi → ibi ipamọ
