Red Thread HP: A High-Performance FRP Piping Solution for Water-Based Industrial Applications

Red Thread HP

Introduction

Industries that manage large-scale water transport and treatment systems need piping solutions that are durable, lightweight, and cost-effective. Red Thread HP is a fiberglass-reinforced plastic (FRP) piping system engineered to meet the demands of such applications. Designed for high-pressure water systems, Red Thread HP combines mechanical strength, corrosion resistance, and simplified installation, making it ideal for infrastructure, water treatment, and utility applications.

In this blog, we’ll take a closer look at the features, benefits, and common applications of Red Thread HP — a versatile and reliable solution for water-focused industrial environments.

 

What is Red Thread HP?

Red Thread HP is an advanced filament-wound FRP piping system manufactured using a thermosetting aromatic amine-cured epoxy resin. It is designed to deliver consistent performance in pressurized water handling systems and general-purpose fluid transport.

Available in sizes ranging from 2 to 42 inches and with pressure ratings up to 25 bar (362.5 psi), Red Thread HP can operate efficiently in systems with continuous temperatures up to 93°C (200°F) and a maximum of 99°C (210°F) with pressure derating applied.

 

Key Features of Red Thread HP

1. Superior Construction and Durability
Red Thread HP pipes are filament-wound according to ASTM D2996 standards, with fittings manufactured through filament-winding or compression molding. All components comply with ASTM D5685 and ASTM D4024.

2. High-Pressure Capabilities
Capable of handling pressures up to 362.5 psi, Red Thread HP is suited for water systems that require both reliability and performance under pressure.

3. Corrosion Resistance
Though unlined, Red Thread HP is still resistant to many forms of environmental corrosion, making it suitable for long-term water handling in outdoor or buried installations.

4. Efficient Jointing System

  • 2" to 6" sizes: Use Threaded and Bonded (T.A.B.) joints for a leak-tight seal.
  • Larger sizes: Use matched tapered bell and spigot joints for enhanced strength and stability.

5. Wide Size Range and Configuration Options
With a variety of diameters, lengths, and pressure ratings, Red Thread HP is easily adaptable to different system layouts and project requirements.

6. Lightweight and Easy to Install
Compared to metal alternatives, Red Thread HP’s lightweight nature reduces the labour, equipment, and costs associated with transportation and installation.

 

Applications of Red Thread HP

1. Water Distribution Systems
Municipal and industrial water supply systems benefit from Red Thread HP’s lightweight construction, ease of jointing, and resistance to long-term wear.

2. Water Treatment Facilities
Ideal for transporting processed and raw water in treatment plants, Red Thread HP supports consistent performance in environments that prioritize system reliability and uptime.

3. Industrial Utility Systems
Used for cooling water, greywater transport, and general-purpose utility water systems, Red Thread HP is well-suited for non-aggressive fluid movement in manufacturing and infrastructure sectors.

4. Infrastructure Projects
Red Thread HP is increasingly used in piping for large infrastructure developments where ease of installation and long-term performance are key considerations.

Alternatively, for environments requiring a resin-lined alternative for more aggressive applications, consider Green Thread® HP, which offers enhanced chemical resistance while maintaining similar structural integrity.
