A resin-rich layer, the thickness of the layer and the type of resin depend on the nature of the fluid in the tube and the operating conditions.
Manufactured by filament winding from continuous fiberglass yarns coated with vinylester or polyester resin, and deposited on a rotating mandrel by a machine.
The machine consists of a rotating mandrel, a dispensing arm that moves along the rotating mandrel, depositing the material at a defined angle, a storage area for the fiberglass and a resin bath.
The mandrel can be replaced by a tube of the required material, which then forms the liner of the tube.
This manufacturing technique allows the use of fiberglass reinforcement in the circumferential direction.
When these pipes are used in underground or high-pressure applications, the majority of loads are concentrated in the circumferential direction of the pipe, which is why the incorporation of continuous glass fiber reinforcement in this direction results in a more efficient product.
Winding angle is a fundamental parameter in all GRP pipes manufactured by filament winding.
This angle directly governs the relationship between the circumferential and axial characteristics of the designed tube, that is, the relationship between the axial pressure (axial tensile strength).
A pipe designed with a winding angle exceeding 65° is a pipe with optimal circumferential properties but low axial efficiency.
For underground installations, a winding angle close to 65° is proposed to ensure superior resistance against ground load, vertical loads and internal pressure.
On the other hand, for overhead installations, the winding angle will be close to 55°, as the tube must be supplied with superior characteristics in the axial direction.
Silica can also be used to increase tube rigidity.
GCER offers a wide range of tubes and accessories designed to meet the specific requirements of every industrial application. Our products are available in a variety of diameters, pressures and stiffnesses to suit our customers' diverse needs.
Technical specifications :
Each size and specification is carefully selected to ensure optimum performance and compatibility with a variety of industrial applications, from water treatment projects to chemical and petroleum applications.
The methods used to assemble composite tubes play a crucial role in their performance and durability. Here are a few commonly used techniques :
The Spigot-Bell assembly is widely preferred for its many advantages:
This type of connection guarantees a permanent bond by using glass-fiber reinforcements and resin for lamination. Laminate thickness and width depend on tube diameter and specific operating pressures.
Flange assembly is used to connect pipes to other system components, such as valves or similar equipment. This method allows rapid installation and dismantling, facilitating maintenance and system modifications.
GRP (Glass Reinforced Polyester) is a composite material combining polyester resin and glass fibers. This combination gives it high mechanical strength, excellent durability, and remarkable chemical resistance.
GRP (Glass Reinforced Polyester) is a composite material offering an exceptional combination of lightness, mechanical strength, and durability. It is distinguished by its high resistance to corrosion, chemicals, and extreme environmental conditions, making it ideal for a wide range of industrial applications. In addition, its design flexibility allows for the manufacture of custom structures, optimizing the performance and longevity of equipment.
GRP (Glass Reinforced Polyester) cannot be recycled in the same way as traditional plastics. Due to its composite composition—a polymer matrix reinforced with glass fibers—conventional mechanical recycling is difficult. However, there are specialized processes for recovering end-of-life materials, including energy recovery or grinding techniques and reuse in secondary applications (fillers, construction materials, etc.). In addition, research is underway to develop more sustainable recycling methods for composites. GCER remains attentive to these technological developments in order to integrate environmentally friendly solutions into its processes.

GCER operates in various sectors, including : • Water and water desalination • Wastewater • Chemicals • Agri-food • Energy • Mining • Oil • Environment • Industrial processes
GCER specializes in : • Composite materials (GRP) • Thermoplastics such as HDPE, PVC, PPH, PVDF, PVC-C, ECTFE, and PFA • Metal construction
To find out if thermoplastic or GRP equipment has reached the end of its service life, check for : • Cracks or deformations. • Loss of resistance to stress. • Leaks or damaged seals. • Reduced performance after testing or inspections. It is important to follow the manufacturer's recommendations and carry out regular checks.
GRP (Glass Reinforced Polyester) is generally more expensive than thermoplastics. This difference is due to a more complex manufacturing process and the use of reinforced materials. However, GRP offers better mechanical and chemical resistance, making it ideal for demanding applications.
GRP (Glass Reinforced Polyester) pipes offer many advantages : they are highly resistant to corrosion, lightweight and easy to install, and require little maintenance. They are also durable with a long service life, and offer good thermal insulation, making them a reliable and economical solution for many industrial environments.
