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:
Petrochemicals and Chemical Plants
Oil and Gas
Mining and Mineral Processing
Dynaflow research group is participating in joint industry projects like the European sponsored Geothermica project (e.g. GRE-GEO under Renewable Energy).
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.
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.
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.
