GRP / GRV Piping Systems

Strength where performance matters

Products

Composite Tanks & Vessels

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.
