1. Lo lus nug: Dab tsi yog cov ntawv thov tseem ceeb ntawm cov nickel -raws li seamless fitting kav thiab raj?
Teb: Lawv tau siv dav hauv aerospace, kev ua tshuaj lom neeg, petrochemical, tsim hluav taws xob, siab - qhov cub kub, thiab kev siv dej hiav txwv. Lawv haum rau tuav cov xov xwm corrosive, siab - cov kua dej siab, thiab qhov kub thiab txias ib puag ncig.
2. Nqe lus nug: Cov khoom tseem ceeb ntawm Inconel 718, 600, 625, 738, thiab 713C yog dab tsi?
Teb:
Inconel 718: Lub zog siab ntawm qhov kub siab, zoo heev oxidation thiab corrosion kuj.
Inconel 600: Zoo oxidation kuj thiab corrosion kuj nyob rau hauv ntau yam tshuaj.
Inconel 625: Exceptional oxidation kuj, siab - kub lub zog, thiab kuj rau chlorides thiab acids.
Inconel 738: Nickel-raws li superalloy nrog siab creep tsis kam, haum rau turbine Cheebtsam.
Inconel 713C: Zoo heev -kub creep thiab qaug zog tiv thaiv, feem ntau yog siv nyob rau hauv turbine hniav thiab cav Cheebtsam.
3. Nqe Lus Nug: Cov kav dej thiab cov kav dej seamless no ua raws li cov qauv dab tsi?
Teb: Lawv tau tsim raws li ASTM / ASME cov qauv xws li:
ASTM B163, B444, B622, B637 rau seamless kav thiab raj.
AMS specifications rau aerospace-qib alloys (piv txwv li, AMS 5596, AMS 5662).
Cov qauv no ua kom cov khoom zoo, qhov tseeb, thiab cov khoom siv kho tshuab.
4. Lo lus nug: Qhov zoo thiab kev ntseeg ntawm cov kav dej no tau txheeb xyuas li cas?
Teb:
Kev txheeb xyuas tshuaj muaj pes tsawg leeg rau kev txheeb xyuas cov alloy.
Mechanical xeem: tensile, tawm los, hardness.
Tsis yog -kev kuaj kev puas tsuaj (NDT): ultrasonic lossis eddy tam sim no kuaj rau cov teeb meem sab hauv.
Visual tshuaj xyuas rau saum npoo zoo.
Mill Test Reports (MTRs) yog muab rau cov ntawv pov thawj thiab traceability.
5. Lo lus nug: Yuav tsum tau ceev faj dab tsi thaum lub sij hawm installation thiab siv?
Teb:
Tsis txhob thermal shock thaum cua sov los yog vuam.
Ua kom muaj kev sib raug zoo, kev txhawb nqa, thiab kev sib txuas ruaj ntseg hauv cov kav dej.
Tiv thaiv kev sib cuag nrog cov hlau tsis sib xws kom tsis txhob galvanic corrosion.
Ua raws li qhov siab tshaj plaws kev khiav hauj lwm kub thiab siab cov lus qhia rau txhua hom alloy.
