. New: FRP pipe
New: FRP pipe is a kind of pipe formed by computer-controlled winding process or pultrusion process, which uses resin as the matrix and continuous glass fiber and its fabric as reinforcing materials.
New: Main features
New: High strength, suitable for direct burial under the driveway, without adding a protective layer of soil, which can speed up the construction progress.
New: Good toughness, able to resist damage caused by heavy external pressure and foundation settlement.
New: Good electrical insulation, flame retardant, and heat resistance, and can be used at
high temperatures for a long time without deformation.
New: Corrosion-resistant, long service life, resistant to erosion by various corrosive media such as acids, alkalis, salts and organic solvents, its service life can be up to
years.
New: The inner wall is smooth and will not scratch the cable. The rubber sealing ring socket joint facilitates installation and connection and adapts to thermal expansion and contraction.
New: Small specific gravity, light weight, can be lifted by one person, and installed by two people, which can be greatly shortened
New: short construction period, reduce installation costs, and avoid long exposure time of road excavation , affecting urban traffic order and other issues.
. .New:
New: No electrical corrosion, non-magnetic. Unlike magnetic materials such as steel pipes, the generation of eddy currents will cause the cables to heat up and be damaged.
New: Wide scope of application
New:: Fiberglass cable protection tube is suitable for use as a protective tube when laying cables underground, and can also be used in high-demand situations such as cable crossings such as bridges and rivers. Using matching professional pipe pillow combination, a multi-layer and multi-row multi-duct pipe arrangement can be formed.

New: Connection method
. New:
New: FRP pipes mainly adopt the
type sealing ring socket connection method. Flanges or bonding can also be used in special locations.

New: Application fields
.New:
New: FRP pipes are suitable for protective conduits for laying power and communication cables in various environments. Especially when used in special environments such as cables passing through major traffic intersections and cables crossing rivers and bridges, it can fully reflect its superior properties such as simple construction and high strength. It is widely used
New: electric power, communications, transportation, civil aviation Airports and other infrastructure construction areas. With its unique strong corrosion resistance, smooth inner surface, low transportation energy consumption, long service life, convenient transportation and installation, low maintenance costs and low overall cost, it is widely used in petroleum, electric power, chemical industry, papermaking, urban water supply and drainage, etc. Factory sewage treatment, seawater desalination, gas transportation and other industries.
.New: Features
. .New:
New: Good corrosion resistance. Because the main raw materials of FRP are composed of unsaturated polyester resin and glass fiber with high molecular weight, it can effectively resist corrosion from media such as acids, alkalis, and salts, as well as untreated domestic sewage, corrosive soil, chemical wastewater, and many chemical liquids. Under normal circumstances, the corrosion can maintain the safe operation of pipelines for a long time.
. .New:
New: Good anti-aging and heat resistance. FRP pipes can be used for a long time in the temperature range of
℃ ~
℃, and the specially formulated high-temperature resistant resin can also work normally at temperatures above
℃. Pipes that have been used in the open air for a long time have ultraviolet absorbers added to their outer surfaces to eliminate ultraviolet radiation on the pipes and delay the aging of fiberglass pipes.
. .New:
New: Good frost resistance. Below zero
°C, freeze cracking will not occur after the inside of the pipe freezes.
. .New:
New: Light weight, high strength, easy to transport. FRP pipes are not only light in weight, high in strength, strong in plasticity, easy to transport and install, but also easy to install various branch pipes, and the installation technology is simple.
. .New:
New: The hydraulic conditions are good. The inner wall is smooth, has strong conveying capacity, does not scale, does not rust, and has low water resistance.
. .New:
New: Good designability. FRP pipes can be designed and manufactured into pipes with different pressure levels and stiffness levels according to various specific requirements of users, such as different flow rates, different pressures, different burial depths and load conditions.
. .New:
New: Low maintenance cost. Due to the above-mentioned corrosion resistance, wear resistance, frost resistance and anti-fouling properties of fiberglass reinforced plastic pipes, the project does not require anti-rust, anti-fouling, insulation, heat preservation and other measures and maintenance. There is no need for cathodic protection for underground pipes, which can save project maintenance costs by up to
. .New:
New: Good wear resistance. Put water containing a large amount of mud, sand and gravel into the pipe to conduct a comparative test on the impact of rotational wear. After
thousands of rotations, the wear depth of the inner wall of the detection tube is as follows:
The steel pipe coated with tar and enamel is
, and the steel pipe coated with epoxy resin and tar is
, the steel pipe with surface hardening treatment is FRP pipe
. Therefore, fiberglass has good wear resistance.
. .New:
New: Good electrical insulation. FRP is a non-conductor. The electrical insulation of pipes is excellent. The insulation resistance is between , only
, is five thousandths of steel, and the pipe has excellent thermal insulation performance.
. .New:
New: Small friction resistance and high conveying capacity. The inner wall of the FRP pipe is very smooth, with very little roughness and friction. The roughness coefficient is
, while the value of concrete pipe is
and that of cast iron pipe is
. Therefore, FRP pipe can significantly reduce the fluid pressure loss along the way and improve the transportation capacity. Therefore, it can bring significant economic benefits:
When the transportation capacity is the same, the project can choose FRP pipes with smaller inner diameters, thereby reducing the one-time project investment. Using pipes with the same inner diameter, FRP pipes can be less expensive than pipes made of other materials. Head loss, saving pumping costs. In addition, fiberglass pipes can shorten pumping time and reduce long-term operating costs
