Key Features & Operating Advantages

• Total Immunity to Galvanic Corrosion: 100% non-metallic thermoplastic structure completely eliminates galvanic rusting and frozen threads in chemical baths.
• Thermal Endurance up to +250°C: Retains mechanical structural strength and torque tension at temperatures where PTFE, PPH, and PVC soften.
• Dielectric Isolation & Non-Magnetic: Prevents stray electrical current leakage and short-circuits in electroplating tanks and battery cell rooms.
• Protective Dome Cup Nut Design: Encapsulates exposed bolt threads to prevent aggressive acid condensation and chemical residue accumulation.
• Cleanroom Purity: Ultra-low outgassing and particle shedding certified for pharmaceutical and semiconductor chemical processing.

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.
