1. Dab tsi yog qhov zoo ntawm Inconel 600, 601, 625, thiab Incoloy 800H piv rau cov qauv stainless hlau raj?
Teb:
Siab - qhov kub thiab txias: Khaws cov khoom siv kho tshuab mus txog 1000℃(nyob ntawm qib).
Corrosion resistance: Zoo heev tiv thaiv acids, chlorides, alkaline daws, thiab dej hiav txwv.
Oxidation kuj: Ua tau zoo nyob rau hauv kub thiab oxidizing ib puag ncig.
Creep thiab qaug zog tiv thaiv: Lub neej ua haujlwm ntev dua nyob rau hauv siab - kev ntxhov siab, siab - daim ntawv thov kub.
Durability: Kev ua tau zoo tshaj plaws hauv kev lag luam tshuaj thiab petrochemical piv rau cov qauv stainless hlau.
2. Dab tsi kev lag luam feem ntau siv cov nickel alloy thiab stainless hlau raj?
Teb:
Chemical & Petrochemical Nroj Tsuag: Reactors, piping systems, heat exchangers.
Roj & Roj: Downhole tubing, siab - cov kav dej siab, li qub.
Aerospace & Turbines: Lub cav tso pa tawm, siab -cov kav dej kub, cov khoom siv.
Fais fab tiam: boiler raj, superheaters, chav pipelines.
Marine & Desalination: Seawater piping, twj tso kua mis, tshav kub exchangers.
3. Vim li cas thiaj xaiv cov raj seamless tshaj welded raj rau cov alloys?
Teb:
Lub zog sib xws: Tsis muaj vuam seam tsis muaj zog cov ntsiab lus, zoo tagnrho rau siab - kev pabcuam siab.
Zoo dua corrosion kuj: Seamless tsim tshem tawm weld -induced defects.
Siab -kev cia siab rau qhov kub thiab txias: Cov raj seamless tiv thaiv thermal cycling zoo dua cov raj welded.
Kev tshuaj xyuas & ntawv pov thawj: Yooj yim dua kom dhau hydrostatic thiab NDT cov kev xeem xav tau rau cov ntawv thov tseem ceeb.
4. Kev tshuaj xyuas zoo li cas ntawm cov raj no?
Teb:
Tshuaj muaj pes tsawg leeg (PMI / spectroscopy)
Mechanical tests: Tensile zog, yield zog, elongation, hardness
Tsis yog-Kev kuaj kev puas tsuaj (NDT): Ultrasonic, hydrostatic, lossis eddy- kev tshuaj xyuas tam sim no
Dimensional checks: OD, phab ntsa thickness, ncaj, ntev
Surface finish check: Xyuas kom du nto rau corrosion kuj thiab plating compatibility
Daim ntawv pov thawj: Mill Test Certificate (MTC) rau ASTM, ASME, lossis AISI cov qauv
5. Yuav ua li cas cov neeg muas zaub xaiv txoj cai alloy, raj hom, thiab specification?
Teb:
Kev khiav hauj lwm tej yam kev mob: Kub, siab, thiab corrosive ib puag ncig
Kev xaiv cov khoom siv:
Inconel 600/601/625: Siab -kub corrosion thiab oxidation kuj
Incoloy 800H: Oxidation- tiv taus rau siab - qhov kub thiab txias
AISI stainless hlau: Nruab nrab corrosion thiab kub daim ntaub ntawv
Tube hom: Seamless rau siab - siab / kev pabcuam tseem ceeb; welded rau kev lag luam lossis tsawg - siv zog
Dimensions & kam rau ua: OD, phab ntsa thickness, ntev
Cov ntawv pov thawj & cov qauv: ASTM, ASME, ISO, NACE
