LANDYOUNG FRP(Fiberglass Reinforced Polyester)FGD systerm piping includes FRP spray headers, FRP flange, FRP elbow, FRP slurry piping, FRP air oxide pipe, FRP stacks and chimney.
Helical FILAMENT winding process (Bell and spigot joints)
GRP Pipe is manufactured using the helical (reciprocal) filament winding process by which impregnated glass fiber reinforcement with resin are applied onto a precision steel mandrel in a prescribed pattern. Repeated application of wetted fibers results in a multi-layered structural wall construction of the required thickness.
Continuous FILAMENT winding process (Coupling joints)
GRP Pipe is manufactured on a continuous filament winding machine. This machine consists of a mandrel composed of a helical wound continuous steel band, supported by beams forming a cylindrical shape. As the formed mandrel turns creating a multi-layered structural wall of the required thickness.

FRP FGD system piping is used in the power plant industry& flue-gas desulfurization.

▪ Corrosion resistance: The inner liner of the pipe adopts epoxy vinyl ester resin, it can resist the erosion from the fume and liquid with sulfur, fluorin.

▪ Heat resistance: The inner liner is using the epoxy vinyl ester resin which HDT is 104ºC and 154ºC, it can resist the temperature of 220ºC instantly.

▪ Good abrasion: The abrasion resistant filler has been added during the fabrication of the pipe, the roughness coefficient of inner surface layer and outer surface layer is low, it has good abrasion resistant for the liquid with 15% solid.

▪ Heat shock resistance: The pipe fabricated with epoxy vinyl ester resin, it has good Heat shock resistant, it can avoid the delamination occurs under the condition of heat shock at 200ºC.

▪ Winding process: Using helical filament winding process on computer controlled machines, it can perform reasonable proportioning according to the axial and hoop stress be undertook under it's working condition. It can improve the adhesive property between layers, and the hoop crack occursalso be avoided.

▪ Easy to fabricate: Many nonstandard parts can be made according to the requirements of the installation.

▪ Connection method: Flange connection, butt and wrap connection.

▪ Light weight: 1/4 of steel pipes; 1/10 of concrete pipes

▪ Diameters: DN15 - DN4000

▪ Design pressure: 0~4.0 Mpa

▪ Joint Method: Bell and spigot, Butt and wrap, Flange joint, Expansion coupling joint

▪ Temperature:Up to 220ºC
