Challenges & Solutions For Flange Component

  • 01

    Gasket Face Leakage

    We utilize precise phonographic serration machining on CNC lathes, creating the optimal surface roughness to ensure spiral-wound gasket micro-sealing compliance under load.

  • 02

    Bolt Hole Misalignment

    Simultaneous multi-spindle drilling on indexable fixtures holds pitch circle diameter tolerances within fifty microns, guaranteeing flawless bolt-hole orientation during field piping installation.

  • 03

    Internal Forging Defects

    Utilizing closed-die forging combined with ultrasonic non-destructive testing ensures uniform grain flow, eliminating internal voids or laminations that cause structural pressure failures.

  • 04

    Creep Deformation Stress

    Finite element analysis optimizes the flange hub taper, balancing thickness and weight to prevent distortion during continuous high-temperature, high-pressure piping operation.

  • 05

    Stress Corrosion Cracking

    Engineered low-carbon alloy and controlled post-weld heat treatment eliminate localized residual stresses, preventing micro-cracking across harsh chemical and offshore environments.
