Fiberglass Elbows | Lightweight Corrosion-Resistant FRP Elbow Fittings - CNPS
CNPS Fiberglass Elbows - precision-molded, corrosion-resistant direction changes for chemical, offshore and municipal piping systems.
Product Overview
CNPS fiberglass elbows are high-strength fiberglass elbow fittings made from lightweight, high-strength composite materials that resist corrosive chemicals, seawater and high pressure. They are approximately 60% lighter than steel fittings, are offered in standard 45 and 90 degree angles with customized options available upon request, and provide a design service life exceeding 25 years. The precise molding process minimizes turbulence and pressure loss, enhancing system efficiency while reducing energy consumption and prolonging pump and valve service life. The elbows are compatible with glass fiber and composite pipes.
Why Choose Fiberglass Elbows?
- Approximately 60% lighter than steel elbows, making installation and transportation much more convenient.

🔧Connection / Installation
Fiberglass elbows join glass fiber and composite pipes using the same jointing method as the pipeline (adhesive-bonded socket, bell-and-spigot or flanged connections). When transitioning to metal systems, appropriate couplings and adapters are used. Clean and prepare the joint surfaces, apply the adhesive per CNPS instructions, align the fitting to the required direction, and allow full cure before pressure testing.
⚙️Applications
- Industrial, offshore and municipal applications
- Chemical environments with corrosive process media
- Marine environments where steel elbows rust and have high maintenance costs
- Sharp pipe turns using 90 degree elbows
- Smooth direction conversion using 45 degree elbows
💎Project Customization
CNPS fiberglass elbows can be customized in angle, size and wall thickness to match the pipeline routing and pressure requirements. Send your pipe diameter, required angle and service media to CNPS so the correct elbow configuration can be confirmed.
