The invention discloses a kind of fiberglass sand inclusion aqueduct, including inner liner, structure sheaf and external protection, the structure sheaf includes interior winding layer, sand-embedded twisting layer and outer wrap.The pipeline is the complex of glass fibre and synthetic resin, there is high, corrosion-resistant specific strength, it is impervious good, heat-insulated and low temperature performance well, light specific gravity, small resistance, low cost, nontoxic, it can be used in the conveying of drinking water, service life was up to more than 50 years.
Description
Technical field
The invention belongs to pipe technology field, in particular it relates to a kind of fiberglass sand inclusion aqueduct.
Background technology
Fw Frp Pipe is all successfully applied to oil, chemical industry, chemical fibre industry work in China and world many countries
For anti-corrosion process pipe, power industry also begins to make diversion, desalination, cooling using LARGE DIAMETER FRP pipeline, is more widely used in
Urban construction water supply, diversion, sewer pipeline field, as new material industrial system.
The quantity of industrial city development and application fw frp is growing day by day, and U.S.'s annual growth is 10% or so, and Japan exists
Fw Frp Pipe accounts for 25% in being applied in major diameter water-supply-pipe, and the major diameter water pipe on Middle East ground, to draw seawater pipe, sewage pipe several
All use Fw Frp Pipe.
The diversion of conventional China, water supply project mostly use carbon steel pipe, pipe of cement.Carbon steel pipe corrosion resistance is poor, pipe of cement intensity
It is low, also there is pollution to water quality.Advanced country's superseded pipe of cement diversion, water supply in the world.As Japan must not expressly provide
Using pipe of concrete.And Fw Frp Pipe has specific strength height, light specific gravity, nontoxic, not polluted water, not cooperating microorganisms
And mushroom, the features such as long service life.
As can be seen here, Fw Frp Pipe is increasingly taken seriously.Its cost is suitable with pipe of cement, compares carbon steel pipe
It is low.It is substitution carbon steel pipe, cast iron pipe, the regeneration product of pipe of cement from the point of view of development.
The content of the invention
It is an object of the invention to provide a kind of fiberglass sand inclusion aqueduct.
The purpose of the present invention is implemented by the following technical programs：
A kind of fiberglass sand inclusion aqueduct, including inner liner, structure sheaf and external protection, the structure sheaf include interior winding
Layer, sand-embedded twisting layer and outer wrap.
Further, the inner liner is the fiberglass surfacing mat or resin content 63-66% of resin content more than 70%
Glass fibre knitting felt.
Further, the external protection is resin.
Further, the interior winding layer uses cross winding mode, and the sand-embedded twisting layer uses ring canoe,
The outer wrap uses cross winding mode.
Further, the thickness of the inner liner is 1.5-2mm, and the thickness of the external protection is 0.25-0.5mm.
Further, the resin is without toxiresin.
Resin used by the present invention is no toxiresin, the conveying available for drinking water；Interior winding layer and outer wrap are adopted
Cross winding mode is used, sand-embedded twisting layer uses ring canoe, and obtained RPM has good mechanical property
Energy.
The invention has the advantages that：
The fiberglass sand inclusion aqueduct that the present invention is provided is the complex of glass fibre and synthetic resin, with specific strength it is high,
Corrosion-resistant, impervious good, heat-insulated and low temperature performance well, light specific gravity, small resistance, low cost, it is nontoxic the advantages of, can be used in drinking
The conveying of water, service life was up to more than 50 years.
