1. Dab tsi ua rau GH2132, GH3030, GH3039, GH3128, thiab GH4145 haum rau siab -kev siv kub?
Teb:
High nickel thiab chromium cov ntsiab lus ua kom oxidation thiab corrosion kuj ntawm qhov kub thiab txias.
Kev nkag siab zoo heev, qaug zog, thiab lub zog tensile rau lub sijhawm ntev - kev pabcuam hauv qab thermal stress.
Seamless tsim tsis txhob weld seam tsis muaj zog, muab cov khoom zoo li qub.
2. Dab tsi kev lag luam feem ntau siv cov high -temp seamless kav/tubes?
Teb:
Aerospace: turbine cav shafts, tso ducts, combustor liners
Fais fab kev lag luam: boiler raj, superheater tubes, tshav kub exchangers
Tshuaj & petrochemical: siab -kub reactors, piping systems
Roj & roj: downhole siab - siab tubing, siab -temp pipelines
Industrial furnaces: radiant tubes, cua sov ntsiab, rauv internals
3. Vim li cas thiaj xaiv cov raj seamless tshaj welded raj rau siab -kub GH alloys?
Teb:
Tshem tawm cov ntsiab lus weld seam tsis muaj zog, tseem ceeb rau siab -siab, siab -kub siv.
Ua kom muaj kev sib haum xeeb corrosion nyob ib puag ncig.
Txhim kho kev qaug zog thiab kev ua haujlwm siab.
Yooj yim dua los ua tsis yog -kev kuaj kev puas tsuaj (NDT) rau kev lees paub zoo.
4. Kev tshuaj xyuas zoo li cas ntawm GH series siab -cov kav dej kub / raj?
Teb:
Tshuaj ntsuam xyuas muaj pes tsawg leeg (spectrometer/PMI)
Mechanical tests: tensile, yield, elongation, hardness
Tsis yog-Kev kuaj kev puas tsuaj (NDT): ultrasonic, hydrostatic, lossis eddy- kev tshuaj xyuas tam sim no
Dimensional soj ntsuam: sab nraud txoj kab uas hla, phab ntsa thickness, ncaj
Surface finish check: xyuas kom du nto rau corrosion kuj
Daim ntawv pov thawj: Mill Test Certificate (MTC) rau GH alloy qauv
5. Yuav ua li cas cov neeg muas zaub yuav tsum qhia kom meej cov high -temp seamless raj/piping rau kev yuav khoom?
Teb:
Alloy qib: GH2132, GH3030, GH3039, GH3128, lossis GH4145
Dimensions: sab nraud txoj kab uas hla, phab ntsa thickness, ntev
Mechanical zog los yog kev kho cua sov yuav tsum tau
Nto tiav lossis machining xav tau
Daim ntawv thov tej yam kev mob: kev khiav hauj lwm kub, siab, corrosive ib puag ncig
Daim ntawv pov thawj yuav tsum tau: GH series txheem, ASTM / ASME sib npaug yog tias xav tau
