8. Economy
Because fiberglass does not need to maintain cost, and life is long, so comprehensive benefit is better

Manufacturing technique

There are three main types of GRP production process: reciprocating fiber winding process, continuous fiber winding process and centrifugal pouring process.

1. Reciprocating filament winding process (n) : in this process, the leaching glue tank with rotating mandrel for reciprocating motion, the long fiber glass with a certain Angle relative to the mandrel axial auxiliary, auxiliary Angle (that is, the winding Angle) baptism glue tank movement speed and the ratio of the core mold speed control, soak glue tank translational motion by computerized machine electric control.The number of winding layers increases gradually until the designed wall thickness is reached.After winding, the resin in the product is basically cured.After curing, the mold is removed from the glass tube.
2. Continuous filament winding process (continuous process) : the pipe is made in the continuous advance of the mandrel through a feed station for resin prepreg, non-twist roving, short-cut fiberglass and resin sand mixture.
3.Centrifugal pouring process (n) : in this process, using glass fiber reinforced materials and sand, feeding on the bearing steel in the mould, injection plus unsaturated resin catalyst in die end, make its dipping reinforced material, under the effect of centrifugal force, the resin exchange fiber and filler in the air, so as to create a nonporous compact composite material, the effect of tube wall due to centrifugal force to form a smooth, bright and clean surface layer of rich resin, steel tubes under high temperature curing.Tubes manufactured in this way are also known as glass reinforced plastic sand tubes.

Product Notes

1. Due to the low density and light material, it is easy to install fiberglass grilles floating pipes in areas with high underground water level. Anti-floating measures such as town piers or rainwater runoff drainage must be taken into consideration.

2. In the construction such as opening a tee on the installed FIBERglass grille and repairing pipe cracks, it is required to be similar to the completely dry conditions in the workshop, and the resin and fiber cloth used in the construction should be cured for 7-8 hours. However, on-site construction and repair are generally difficult to meet this requirement.

3. Existing underground pipeline detection equipment is mainly used to detect metal pipelines, while non-metallic pipeline detection equipment is expensive, so it is impossible to detect FRP grilles after they are buried in the ground. Other subsequent construction units are prone to dig and damage pipelines during construction.

4. Fiberglass grilles have poor uv protection.Open-mounted FRP grillers are retarded by the fabrication of a 0.5mm thick resin rich layer and uv absorbent (in-plant processing) on the surface.Over time, the resin rich layer and uv absorbent will be destroyed, which will affect its service life
