FRP Process Piping

I. FRP Slurry Circulation Piping

This is one of the most representative applications of FRP piping, where its advantages are most fully realized. It has almost completely replaced previous solutions such as rubber-lined steel pipe and high-alloy steel pipe.

FRP slurry circulation piping has become the absolute mainstream in this field due to its following irreplaceable advantages:

1. Extreme Corrosion and Abrasion Resistance (their core advantage)

Extreme operating conditions: The circulating slurry typically contains a 10-20% solids content (limestone/gypsum), a pH between 4-6, chloride ions (potentially reaching tens of thousands of ppm), high temperatures (50-80°C), and corrosive media. This combination of "acid, chlorine, and particle abrasion" is catastrophic to metals. Perfect Solution:

Corrosion Resistance: FRP, based on vinyl ester resin (Ve), offers exceptional corrosion resistance in low-pH, high-chloride environments, completely resistant to pitting, crevice corrosion, and stress corrosion cracking common to carbon steel or stainless steel.

Wear Resistance: By adding wear-resistant materials (such as quartz sand and silicon carbide) to the inner lining, or by using a resin-rich layer reinforced with felt, it achieves exceptional wear resistance, effectively resisting erosion from solid particles in the slurry. Its wear resistance surpasses that of ordinary steel pipe.

2. Ultra-Long Service Life and Extremely Low Maintenance Costs

FRP pipes are typically designed to last over 20 years, matching the lifecycle of the installation. Furthermore, FRP itself is corrosion-resistant and age-resistant, requiring virtually no maintenance throughout its lifecycle, saving significant maintenance costs and downtime. Furthermore, it possesses the typical characteristics of FRP pipes: a smooth inner wall, excellent hydraulic performance, low friction resistance, energy efficiency, lightweight and high strength, easy installation, low weight, excellent integrity, and overall economic benefits (the lowest overall lifecycle cost), making its long-term economic performance far superior to any metal alternative.

II. Fiberglass Ductwork

Fiberglass ductwork, also known as fiberglass reinforced plastic ductwork, is a type of ductwork used for air transportation, made with a synthetic resin matrix and reinforced with glass fiber and its products (such as cloth and felt) through processes such as hand lay-up, winding, or molding.

1. Excellent Corrosion Resistance

This is its most notable characteristic. By selecting different resin types (such as acid- and alkali-resistant vinyl ester resin), it can withstand corrosion from various acids, alkalis, salts, solvents, and humid air.

Applications: Ideally suited for ventilation and exhaust systems in chemical, laboratory, electroplating, textile, papermaking, sewage treatment, aquarium, and other industries involving corrosive gases. In these applications, it completely solves the problems of corrosion and short lifespan of traditional metal ductwork.

2. Thermal Insulation (depending on the process)

Fiberglass has a low thermal conductivity, approximately 1/100th that of metal, and possesses considerable thermal insulation properties. If a higher level of insulation is required, insulation materials (such as polyurethane foam) can be added directly during the manufacturing process to create an integrated insulated duct, eliminating the tedious process and risk of detachment associated with traditional external insulation coatings.

What is FRP Process Pipe?

A FRP Process Pipe is a fiberglass-reinforced plastic piping system designed specifically for industrial process applications where continuous fluid transport is required.

Unlike standard FRP Pipe used for general water or drainage applications, FRP Process Pipe systems are engineered for:

● Chemical process flow

● Industrial production lines

● Continuous circulation systems

● High-corrosion environments

In the hierarchy of FRP Pipe systems, the process pipe represents a higher-level engineering application focused on system reliability, safety, and long-term operational efficiency.

FRP Pipe System Hierarchy

To better understand FRP Process Pipe, it is important to see its relationship within the broader FRP piping family:

● FRP Pipe (Base Product) → general corrosion-resistant piping

● FRP Pressure Pipe → pressurized transport systems

● FRP Process Pipe → industrial process and production systems

● FRP Special Application Pipe → chemical & high-corrosion environments

Applications of FRP Process Pipe Systems

● Chemical Processing Industry

Used in acid, alkali, and corrosive fluid transport systems
