1. ASTM B165 yog dab tsi, thiab vim li cas nws thiaj li cuam tshuam rau cov kav dej hlau no?
Teb:
ASTM B165 yog tus qauv specification rau npib tsib xee thiab npib tsib xee- alloy seamless kav. Nws txhais cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, cov txheej txheem tsim khoom, thiab cov kev xeem yuav tsum tau ua. Kev ua raws cai ua kom cov kav dej seamless ua los ntawm Inconel, Incoloy, los yog lwm yam nickel alloys ua tau raws li siab -kub thiab corrosion- tiv taus kev ua haujlwm rau kev lag luam.
2. Dab tsi yog qhov txawv ntawm Inconel 600, 625, 718, C22, C276, Incoloy 825, thiab 800HT?
Teb:
| Alloy | Ntsiab Feature | Kev siv yam | Kub Resistance |
|---|---|---|---|
| Inconel 600 | High corrosion & oxidation tsis kam | Tshuaj, khoom noj, kub exchangers | Mus txog 1200℃F (649 degree) |
| Ib 625 | Siab zog + zoo heev corrosion kuj | Marine, tshuaj, aerospace | Mus txog 1800℃F (982 degree) |
| ib 718 | Cov dej nag-hardenable, muaj zog heev | Gas turbines, nuclear | Mus txog 1300℃F (704 degree) |
| Hastelloy C22 | Kev tiv thaiv zoo rau oxidizing & txo cov acids | Tshuaj, tshuaj | Mus txog 1500℃F (816 degree) |
| Hastelloy C276 | Zoo heev tiv taus pitting & kev nyuaj siab corrosion | Tshuaj, petrochemical | Mus txog 1600℃F (871 degree) |
| lus 825 | Tsis kam rau sulfuric & hydrochloric acids | Tshuaj, petrochemical | Mus txog 1000℃F (538 degree) |
| Inconel 800 HT | Siab - kub lub zog & oxidation kuj | Rauv Cheebtsam, tshav kub exchangers | Mus txog 1200℃F (649 degree) |
3. Dab tsi yog cov khoom siv ntawm DN100 Sch80S seamless kav rau cov hlau no?
Teb:
Tensile Strength (MPa): 450-1250 (nyob ntawm cov hlau thiab kev kho cua sov)
Yield zog (MPa): 200-1100
Elongation (%): 25-50
Hardness: HRB 70-95 los yog HRC 20-35 nyob ntawm alloy
Cov kav dej no yog tsim los tswj lub zog thiab ductility nyob rau hauv qhov kub thiab txias.
4. Yuav ua li cas corrosion kuj yuav tsum tau los ntawm cov alloys?
Teb:
Inconel 600/625/718: Zoo heev tiv thaiv oxidation thiab siab -kub corrosion; zoo tiv thaiv alkalis thiab me ntsis acids.
Hastelloy C22 / C276: Zoo heev tiv thaiv oxidizing thiab txo cov kua qaub, chlorides, thiab dej hiav txwv.
Incoloy 825: Resistant sulfuric, hydrochloric, thiab phosphoric acids, nrog rau cov tshuaj chloride-induced stress corrosion.
Inconel 800HT: Resistant rau oxidation thiab carburization ntawm siab kub.
5. Dab tsi yog cov ntawv thov kev lag luam rau cov kav dej seamless?
Teb:
Chemical & Petrochemical Nroj Tsuag: Siv cov kua qaub, chlorides, thiab corrosive kua
Fais fab Tsim & Kub Exchangers: Siab-kev pab kub
Marine & Offshore: Seawater piping, dej ntsev tuav
Aerospace & Gas Turbines: Siab- lub zog, siab - qhov kub thiab txias yam ntxwv
Pharmaceutical & Food Processing: Corrosion-resistant piping systems
