From innovation to application

Fiberglass Reinforced Plastic has found its way into the industry and has been applied for more than 3 decennia in the oil and gas industry, chemical industry and power plants. More and more applications are found where fiberglass piping is a more sustainable choice than steel piping. 

Typical applications are:

  • Powerplants

  • Renewable Energy

  • Petrochemicals and Chemical Plants

  • Food Processing

  • Oil and Gas

  • Mining and Mineral Processing


Industries where FRP is being applied



Typical applications of fiberglass in powerplants are coolingwater, wastewater and firewater lines. Coolingwater and firewater systems are a critical assets and require a solid design. Cooling water systems are usually installed both aboveground and underground and require special attention with relation to e.g. soil settlement and traffic loads.

Petrochemicals and Chemical Plants

Petrochemicals and Chemical Plants

Typical fiberglass applications in the (Petro)-chemicals industry are cooling water systems, firewater systems, chemical fluid transport, sometimes using polymer lined fiberglass systems “dual-laminates” to enhance the chemical compatibility, and wastewater systems. Also storage tanks are built from fiberglass.

Food Processing

Food Processing

Fiberglass is applied in the food processing industry for cooling water, waste water and firewater (deluge) systems. Fiberglass has very good corrosion resistance and food safety qualities, making it a safe choice for food processing applications.

Oil and Gas

Oil and Gas

In the oil and gas industry fiberglass is used for crude oil transport  pipelines (trunk lines and flowlines), high pressure water injection systems, cooling water, firewater systems, oil water separation plants and water-treatment/demineralization plants.

Mining/Mineral Processing

Mining/Mineral Processing

Fiberglass is used in the mining industry for cooling water piping, fire water,  aggressive fluid transport (dual laminated products with polymer liners e.g. PE, PVDF, PFA), wastewater piping and acid storage tanks.


Joint Industry Projects

Dynaflow research group is participating in joint industry projects like the European sponsored Geothermica project (e.g. GRE-GEO under Renewable Energy). 

Logos of FRP standards NEN, ISO, and DNV

Standardization (ISO/NEN)

Because of our active involvement in ISO, DNV and NEN committees from the early start of the application of FRP. Our software and knowledge is always up to date and meets the most recent international standards. This makes our services unique worldwide and has provided DRG a leading role as an engineering company specialized in FRP applications.​

Firewater systems

Firewater is of vital importance in many different industries. Using fiberglass piping for firewater systems has a number of advantages like the corrosion resistance of fiberglass piping.

Geothermal Well Tubing​​

The energy transition has caused an increasing interest in Geothermal wells for industrial and domestic heating purposes. Geothermal energy is already being used in the agriculture industry for the heating of greenhouses.

The design of FRP piping for geothermal tubing comes with specific challenges related to loading conditions that differ from standard process piping. Dynaflow’s experience has been applied successfully to overcome the more complex thermal. Hydrostatic and mechanical loads acting on the tubing present in a geothermal well. 

Chemical Services

The selection of a piping system for chemical service depends on the fluid and temperature to be transported. Both the resin type and glass type determine the chemical compatibility of the piping system. For instance, caustics service requires another resin and glass fiber type than acid service. 

For severe chemical fluids like for example sodium-hypochlorite or high concentration hydrochloric acid lines (desalination/denim plants) dual laminated systems with a corrosion resistant liner is often specified.

For each chemical service an optimum combination of resin and glass reinforcement can be selected. The design and qualification of such systems deviate from that of “standard” FRP products, and therefore needs special attention. Also, the chemical compatibility and type of seal/gasket needs to be selected carefully.
