Product Description

Fiberglass reinforced plastic (FRP) sandwiched pipe is a new type of composite material made of resin as matrix material, glass fiber and its products as reinforcing material and quartz sand as filling material. It has become a good choice for chemical industry, drainage project and pipeline project because of its good corrosion resistance, hydraulic characteristics, light weight and high strength, large conveying flow, convenient installation, short construction period and low comprehensive investment.

Main advantages

1. Excellent corrosion resistance: the product selection of corrosion-resistant resin, with good mechanical properties and processing characteristics, in most of the acid, alkali, salt water untreated sewage, corrosive soil or groundwater and many chemical substances.

2. Good heat and cold resistance: in the -30 ℃ state, still has good toughness and high strength, can be in the range of -50 ℃ -80 ℃ for long-term use, the use of specially formulated resins can also be 110 ℃ when used.

3. Good wear resistance: FRP pipe wear resistance is very good, the test proved: the water containing a lot of mud, sand and gravel, loaded into the tube for rotating wear impact comparison test. After 300,000 rotations, the depth of wear in the test tube is as follows: 0.53mm with tar and ceramic oil coated steel pipe; 0.48mm by the surface hardening treatment of the steel pipe; fiberglass reinforced plastic pipe for 0.21mm, which can be explained by the fiberglass reinforced plastic pipe wear-resistant performance is very strong.

4. Anti-fouling resistance after curing: In the process of use, no scaling, no rust, will not be the sea or sewage in the shellfish, bacteria and other microorganisms tainted with moths.

5. Fewer interfaces, high installation efficiency: the length of the pipe is generally: 6-12m/pipe (we can also produce a special length of pipe according to customer requirements). Single pipe length, the number of interfaces is small, thus speeding up the installation speed, reducing the probability of failure, improve the quality of the installation of the entire pipeline.

6. Good mechanical properties, excellent insulating properties: the tensile strength of the pipe is lower than that of steel, higher than that of ductile iron pipe and concrete pipe, while the specific strength is about 3 times that of steel pipe, 10 times that of ductile iron pipe and 25 times that of concrete pipe. In addition, its thermal conductivity of only 1% of the steel pipe, has excellent insulation, adapt to use in power transmission, telecommunications lines in dense areas and mine areas.

7. Long and reliable service life; FRP sandwiched pipe is designed with high safety coefficient. According to the laboratory simulation test table: general water supply, drainage sand sandwiched fiberglass reinforced plastic pipe life of up to 50 years or more, is the steel pipe and concrete pipe 2 times. For the more corrosive media, its service life is much higher than that of steel pipe.

Performance introduction

1. High strength: strong resistance to external loads, FRP sandwiched pipe can be directly used for direct burial under the roadway, without the need to construct a protective layer of concrete, can speed up the progress of construction, thus greatly reducing construction costs, with significant social and economic benefits.

2. Corrosion resistance: specially designed FRP sandwiched pipe can resist acid, alkali, salt, untreated sewage, corrosive soil and groundwater and many other chemical fluids, by the traditional pipeline service life is long, and its design service life reaches more than 50 years.

3. Good flame retardant, heat and frost resistance: FRP sandwiched can be used for a long time at -20℃-100℃ without deformation.

4. Good electric insulation performance: no vortex loss and electric corrosion energy saving, DN200 below FRP pipe is suitable for cable laying; large flow-carrying capacity, small thermal resistance, the normal operation of the cable does not have any adverse effects;.

5. Quick and convenient construction and installation: FRP sandwiched pipe adopts socket type connection, which is convenient for installation and connection; double O-type rubber ring is adopted at the joint to adapt to thermal expansion and contraction.

Main Uses of Fiberglass Reinforced Plastic Pipe

Usage: Used in all kinds of municipal sewage treatment, water supply and tap water transportation, farmland irrigation, petrochemical industry.
