FRP Mortar Pipe

Quartz sand as a reinforcing material into the structural layer, based on FRP
wound pipes . Their structure typically consists of: an inner lining (resin-
rich layer for corrosion and seepage prevention) → a structural layer (glass
fiber for strength) → a sand-filled layer (resin + quartz sand for rigidity
and cost reduction) → an outer protective layer (anti-aging and anti-
corrosion).
Characteristics of FRP Mortar Pipe
The design of fiberglass reinforced plastic (FRP) sand-filled pipes cleverly
combines the advantages of multiple materials, giving them the following
outstanding characteristics:
1. Extremely high stiffness and resistance to external pressure
Core Purpose : The main function of the sand-filled layer is to significantly
improve the ring stiffness of the pipeline . After the quartz sand is mixed
with resin, a hard "composite mortar" layer is formed, which enables the
pipeline to effectively resist the huge external pressure of soil load, ground
live load (such as vehicles) and groundwater, preventing the pipeline from
deforming and flattening.
High design flexibility : By adjusting the thickness of the sand layer, FRP
Mortar Pipes with different stiffness grades (such as SN5000, SN10000) can be
flexibly produced to meet the requirements of different burial depths and
geological conditions.
2. Excellent corrosion resistance
FRP Pipe inherits all the corrosion-resistant advantages of fiberglass pipes.
The inner lining consists of a high resin content and a surface felt, providing
an excellent barrier against corrosion and seepage.
