The FRP filament winding pipe mandrel is a key forming component in the composite pipe production line. It provides a precise shaping surface for fiberglass and resin during high-speed winding. Its dimensional accuracy and surface quality directly determine the structural strength, roundness, and inner surface finish of the final pipe.
The mandrel is manufactured using high-strength steel or composite structures with precision machining and surface treatment, ensuring high rigidity and excellent wear resistance.
· High-strength core shaft
Provides stable structural support
· Precision surface layer
Ensures smooth inner pipe surface
· Modular segmented structure
Easy assembly and maintenance
· Thermal expansion compensation system (optional)
Maintains dimensional stability under heat
· High dimensional accuracy for perfect pipe geometry Excellent surface finish for smooth inner wall
· High strength structure for heavy-duty winding pressure
· Long service life with wear-resistant treatment
· Modular design for easy replacement and maintenance
· Compatible with different FRP winding systems
Widely used in high-end FRP pipe manufacturing:
· FRP pressure pipe production
· Chemical corrosion-resistant pipelines
· Oil & gas transportation systems
· Desalination and water treatment pipelines
· Industrial wastewater and circulation systems
· Large-diameter structural and custom pipes
The FRP winding mandrel is not just a forming tool—it is a critical engineering core that determines final product quality. A high-precision mandrel significantly improves structural consistency, production efficiency, and overall performance stability.
