Key Features & Operating Advantages

• Low Seating Stress for Plastic/FRP Flanges: Eliminates flange cracking or bowing on thermoplastic and fiberglass pipe flanges caused by excessive bolt torque.
• Universal Chemical Wetted Surface: Chemically inert PTFE wetted face is impervious to 99% of corrosive acids, alkalis, and solvents.
• High Elastic Recovery (Memory): EPDM core absorbs thermal cycling, pipeline expansion, and pressure pulsations without losing sealing stress.
• Dual Concentric Sealing Ridges: Features molded concentric sealing convex rings for bubble-tight seal at low bolt compression.
• Reusable & Long Lifespan: Prevents gasket adhesion and sticking to flange faces during line maintenance.

Quality Assurance, Testing & Compliance

At ASK Innocomp, quality control is integrated at every manufacturing step:

• High-Voltage Dielectric Spark Testing (20,000V): 100% verification of non-porous fluoropolymer coatings and lining integrity.
• Hydrostatic & Tensile Load Testing: Proof pressure tested to 1.5x working rating with tensile pull verification.
• Laser Dimensional Measurement: Precision tolerance checks ensuring exact interchangeability with standard plant flanges and fittings.
• Mill Test Certificates (EN 10204 3.1): Full raw material batch traceability provided with every dispatch.

Recommended Industrial Applications

• FRP, PPH, PVDF, HDPE, and PVC flanged piping connections
• Chemical storage tank nozzle flanges and decanting valve manifolds
• Water treatment demineralization skids and RO header flanges
• Acid pickling recirculation piping and scrubber inlet/outlet duct flanges
