GRP / GRV Piping Systems

Overview

Amiantit GRP and GRV piping systems are designed for corrosion-resistant fluid transmission in infrastructure, industrial, and utility applications. Manufactured using continuous filament winding technology, these composite pipelines provide high structural strength, smooth hydraulic performance, and long service life in demanding environments.
The systems are suitable for gravity and pressure applications, including water transmission, drainage networks, industrial services, and trenchless installation methods.

Key Benefits

Amiantit GRP / GRV piping systems are available with multiple jointing solutions depending on pipe diameter, pressure rating, installation method, and service conditions.

  • Double Bell Coupling (REKA EPDM Seal)
    Suitable for buried pipelines, gravity systems, and jacking installations.
  • Flanged Joints
    Used for above-ground installations and equipment connections.
  • Laminated (Butt & Wrap) Joints
    Applied for large diameters, special fittings, and site-fabricated connections.
  • Mechanical Couplings
    Used for repairs, transitions, and special applications.

Material & Construction

  • Continuous filament-wound composite construction
  • Corrosion-resistant internal liner with C-glass and polyester or vinyl ester resins
  • Reinforced structural laminate with E-glass fibers (sand-filled or non-sand filled)
  • Smooth internal bore providing excellent hydraulic performance
  • UV-resistant external protective finish

Key Advantages

  • Excellent corrosion and chemical resistance
  • Lightweight compared with steel and ductile iron pipelines
  • Long service life with minimal maintenance
  • Smooth internal surface reduces friction losses
  • Cost-effective lifecycle solution
