GRP (Glass Reinforced Plastic) pipes and fittings are lightweight yet high-strength composite piping components made from polyester or vinylester resins reinforced with glass fibers. These corrosion-resistant systems are engineered to perform reliably in aggressive, corrosive environments where metallic or traditional piping systems fail or require excessive maintenance.

GRP piping systems are widely used across water treatment plants, desalination projects, irrigation networks, chemical processing units, power plants, and offshore/onshore infrastructure. They are ideal for both above-ground and buried installations due to their excellent resistance to rust, scaling, and biological growth. GRP’s low thermal conductivity also helps in minimizing insulation requirements in fluid transport applications.

At Middle East Piping, we offer a comprehensive range of GRP pipes and fittings tailored to project-specific pressure ratings, diameters, and installation methods. Our GRP fittings portfolio includes elbows, reducers, tees, stub ends, flanges, couplings, and custom-molded pieces, compatible with various joining methods such as butt & wrap, adhesive bonding, and mechanical couplings.

Manufactured in compliance with international standards like ASTM D3262, ISO 14692, and AWWA C950, our GRP products undergo strict quality control and are supplied with full hydrotest reports, lamination schedules, and mechanical property documentation. GRP piping systems are available in pressure classes ranging from 6 to 32 bar and in diameters up to 4000 mm. click here

Whether you’re building a new industrial plant, expanding a utility network, or retrofitting pipelines in corrosive environments, GRP pipes and fittings offer a durable, non-metallic solution with a 50+ year service life and low life cycle cost. click here
