Fiberglass reinforced plastic sand pipe is a new composite material made of resin as matrix material, glass fiber and its products as reinforcing material and quartz sand as filling material. With its excellent corrosion resistance, hydraulic characteristic, high strength, large delivery flow, convenient installation, short construction period and low investment, the best choice in the chemical industry, water supply and drainage engineering and pipeline engineering.
Fiberglass reinforced plastic pipe products
[excellent corrosion resistance]
The product selects the corrosion resistant extremely strong resin, has the extremely good mechanical property and the processing characteristic, in most acid, alkali, salt seawater untreated sewage, corrosive soil or groundwater and many chemical substances erosion.
Good heat resistance and cold resistance.
At -30 DEG C, still has good toughness and high strength, can be used for a long time in the range of -50 DEG C 80 DEG C, resin with special formula can also be used when 110 DEG C.
Good wear resistance.
Wear resistance of the glass pipe is very good, the test proved that: contains a lot of mud, sand water, rotating wear contrast test tube into effect. After 300 thousand times of rotation, detecting the wear depth of the inner surface of pipes are as follows: steel and porcelain oil tar coating is 0.53mm; the surface hardening treatment for steel 0.48mm; FRP pipe is 0.21mm, which can explain that the wear resistance of the glass pipe is very strong.

[thermal insulation performance]
Because of the low thermal conductivity of FRP products, so its thermal insulation performance is particularly good.
After curing, anti fouling resistance
In the process of using no fouling, no rust, not by sea or sewage in shellfish, fungi and other microbial contamination of borers.
Small interface, high installation efficiency
The length of the pipeline is generally: 6-12m/ root (also according to customer requirements to produce a special length of pipeline). Single pipe length, the number of interface, thereby speeding up the installation speed, reduce the probability of failure, improve the installation quality of the whole pipeline. Jiangsu
[proportion is small, the quality is light]
The steel glass tube produced by filament winding has a specific gravity of 1.65 - 2, only 1/4 of steel, but the hoop tensile strength of glass fiber reinforced plastics is - 300MPa, the axial tensile strength is between - 60 and 150MPa. Therefore, its specific strength (strength / gravity) is 2-3 times the alloy steel, so that it can according to the different requirements of users, designed to meet all kinds of internal and external pressure requirements of the pipeline. For the same diameter of single FRPM tube, only carbon steel (steel plate) 1/2.5, 1/3.5 cast iron pipe, prestressed reinforced concrete pipe is about 1/8, so the transportation is very convenient for installation.
[mechanical properties, excellent insulation performance]
The tensile strength of the steel pipe below, above the ductile iron pipe and concrete pipe, and the ratio is about 3 times stronger than steel, 10 times of ductile iron pipe, concrete pipe 25 times. In addition, its coefficient of thermal conductivity of steel is only 1%, has good insulating property, suitable for use in power transmission and telecommunication line area and multiplexers.
Excellent hydraulic performance and energy saving
FRP pipe has a smooth inner surface, suitable for large diameter (= Phi 500mm) characteristics of the pipeline, the friction coefficient is small, the hydraulic fluid characteristics, and the larger the diameter the more obvious advantage. On the contrary, in the case of the same pipeline delivery flow, the project can use the smaller diameter of sand glass pipe instead of steel, thereby reducing the one-time project investment. Compared with other pipes, the sand glass fiber reinforced plastic pipeline can greatly reduce the loss of the head and save the power and energy of the pump.
[service life long, safe and reliable] glass fiber reinforced plastic pipe design safety factor high. According to the laboratory simulation test table: general water supply, drainage sand glass pipe life can be more than 50 years, is the steel pipe and concrete pipe of 2 times. For corrosive medium, its service life is much higher than steel pipe, etc..
[design flexibility, product adaptability]
Sand glass fiber reinforced plastic pipe can be based on the user's special use requirements, through the change design, manufacturing a variety of specifications, pressure rating, stiffness grade or other special properties of the product, wide application.
[] due to low cost for operation and maintenance of glass steel products has good corrosion resistance, without rust proof, anti fouling, insulation, insulation and other measures and maintenance of underground pipe without cathodic protection, can save a lot of maintenance costs.
[engineering comprehensive benefit]
The comprehensive benefit is long term by various factors of construction investment, installation and maintenance costs, service life, saving energy and steel form, the comprehensive benefits of FRP pipe is desirable, especially the larger diameter, the cost is low. When further consider buried underground pipeline can be used for several generations, without annual maintenance, but also can play its superior comprehensive benefits.
Product performance introduction:
[high strength]
The anti load ability, gfrpmp can be directly directly buried under the carriageway and don't need to build a protective layer of concrete, can speed up the construction progress, thus the construction cost is greatly reduced, with significant social and economic benefits.
Corrosion resistance
Through specially designed glass steel sand tube can resist acid, alkali and salt, without erosion of sewage, soil and groundwater and other corrosive chemical fluid, the traditional pipeline has long service life, the design service life of 50 years.
[flame retardant, heat resistance and good frost resistance]
Glass fiber reinforced plastic sand can be in - 20 - - 100 degrees of long-term use without deformation.
Good electrical insulation performance.
