Ingot Smelting: Siv vacuum induction melting + electroslag remelting (VIM+ESR) txheej txheem los ua kom cov ingot muaj purity thiab uniformity.
Hot Working: Ua multi-pass hot piercing thiab hot rolling los tsim lub kav khoob, tswj tus nqi deformation kom tsis txhob muaj microstructure defects.
Cold Working: Siv cold rolling lossis cold drawing rau multi-pass forming, tswj qhov sib txawv ntawm outer diameter hauv ±0.1 mm, thiab txhim kho dimensional accuracy thiab mechanical strength.
Heat Treatment: Ua solution treatment ntawm 1120–1170°C tom qab ntawd txias sai, tshem internal stress, thiab tau txais uniform austenitic structure.
Quality Inspection: Siv ultrasonic flaw detection, eddy current testing, hydrostatic testing, kev tshuaj xyuas tshuaj lom neeg, thiab kev sim khoom siv tshuab los xyuas kom tsis muaj qhov tsis zoo ntawm cov kav tiav.
Kev Lag Luam Tshuaj Lom Neeg: Reactions, heat exchangers, khoom siv pickling, cov kav dej chlor-alkali plant
Kev Lag Luam Tiv Thaiv Ib Puag ncig: Flue gas desulfurization (FGD) systems, khoom siv kho dej khib nyiab
Kev Lag Luam Hluav Taws Xob: Cov kav dej roj av exploitation, cov kav dej tshuaj lom neeg kub siab thiab siab
Kev Lag Luam Marine: Tej yaig dej hiav txwv desalination, cov kav dej tiv thaiv corrosion offshore platform
Kev Lag Luam Tshuaj thiab Khoom Noj: Cov kav dej thauj medium siab purity
Kev Hloov Kho Rau Medium: Xaiv ua ntej rau cov kev ua haujlwm uas muaj chloride ions, mixed acid-base media thiab alternating oxidizing/reducing environments; Rau ib leeg reducing media muaj zog, piv nrog Hastelloy C276.
Kev Xaiv Specification: Xaiv SCH series raws li qhov siab rating, nrog corrosion allowance ≥1.5 mm; Xam creep strength rau cov kev ua haujlwm kub siab.
Kev Tsim Ntawv Pov Thawj Zoo: Thov Mill Test Certificate (MTC) suav nrog tshuaj lom neeg, khoom siv tshuab, thiab cov ntawv qhia kev sim tsis rhuav (non-destructive testing).
Kev Sib Tw Vuam: Siv tib qib vuam hlau (xws li ERNiCrMo-10), tswj cua sov thaum vuam, thiab tsis tas yuav ua post-weld heat treatment.
Khaws hauv tsev khaws khoom qhuav thiab cua tshuab, tsis txhob sib xyaw nrog cov khoom carbon steel los tiv thaiv electrochemical corrosion.
Tsis txhob sib tsoo thaum thauj los tiv thaiv qhov chaw puas; Tshem cov roj thiab impurities ua ntej teeb tsa.
Ntxuav cov vuam tom qab vuam, thiab ua pickling thiab passivation yog tias tsim nyog los txhim kho kev tiv thaiv corrosion.
