White FRP pipes with polyurethane paint

FRP pipe is in the filament winding process, using quartz sand layer will strengthen, make its have sandwich structure, such as reducing the comprehensive cost of the pipeline, and improve the overall strength and stiffness of the pipeline.

This kind material is fully impregnated with resin, the mixture of continuous glass fiber, glass fiber rovings, continuous mat, surface mat and so on  reinforcing material, through the mold and heat cured in the mold cavity, under the action of traction mechanism rally, can be  continuous pulled infinite length of FRP pultruded profiles. Pultruded profiles can be re-shaped highly, all kinds shape of pultruded profiles can be made into a variety of steel products through appropriate combination

Charateristic:
— Light weight, high strength, and convenient transportation and installation.
— Excellent corrosion resistant, it can be used under the condition of seawater environment for long time.
— Good low temperature resistant, it can be used under the condition of -45°C-120°C for long time.
— Smooth inner surface, its roughness coefficient is 0.0084, good conveying, and no fouling, no secondary pollution, 

decrease the cost of the running & maintenance.
— Fire retardant, it meets IMOA.753(18) Level-3 fire resistance class.
