Information

There are two forming methods for FRP pipes, one is a fixed-length pipe and the other is a continuous pipe. The FRP pipe has a series of excellent properties such as corrosion-resistance, anti-fouling and moth-resistance, heat resistance, freezing resistance and good designability, which is widely used in water supply and drainage industry. Similar to container shaping, except that no head is required for a pipe. Generally, the winding Angle greater than 54.7 degrees is returned at the end of the pipe with the winding Angle approaching 90 degrees. The fiber accumulation at the end of the pipe is large. The annular strength and stiffness of the joint are used to guarantee the sealing performance. The connection of large-caliber long-distance transportation pipeline USES o-ring socket connection, and the two ends of a single pipe are made into a form of Yin and Yang. The short-distance surface process pipelines are mostly bonded.

 

Process pipeline needs a large number of pipe fittings, such as tee, elbow, etc. High-performance piping and pipe fittings are formed by continuous fiber winding. The winding of pipe fittings is much more complicated than that of straight pipes and vessels. Although multi-axis and even mechanical hand-type pipe winding units have been developed at present, they cannot be popularized in the manufacturing of industrial pipe fittings due to economic reasons. Therefore, most of the wrapped pipe fittings are done by hand. In buried large diameter pipeline, sand - clamping pipeline has been developed to reduce cost and improve stiffness of external pressure.

 

Ten advantages of new building materials - fiberglass

Compared with other materials, pipes have the following remarkable advantages:

 

1. Corrosion resistance and no pollution

GFRP pipes are resistant to the erosion of acids, bases, salts, seawater, untreated sewage, corrosive soil or groundwater, and numerous chemical fluids. The GFRP pipe is widely used in water supply and drainage industry because of its excellent characteristics of non-toxic, rustless, tasteless, no secondary pollution to water quality and no need of antisepsis.

 

2. Stain and mothproofing

Unsaturated polyester resin is used on the surface of the pipe, so its surface is clean and smooth, and will not be contaminated by sea or sewage by microorganisms such as shellfish and fungi, resulting in increased roughness, reduction of cross section of water, and increase maintenance costs. The pipe is free of such pollution and will remain clean for a long time.

 

3. Heat and frost resistance

Under - 30 ℃ condition, still has good toughness and high strength, can be in - 50 ℃ to 80 ℃ within the scope of use for a long time, the use of special formula of resin can also work at temperature above 110 ℃.

 

4. Light weight, high strength, high transportation, convenient installation and convenient installation of FRP pipes produced by fiber winding process, with a proportion of 1.65-2.0, only 1/4 of steel, but the circular tensile strength of glass steel pipes is 180-300mpa and the axial tensile strength is 60-150mpa, similar to alloy steel. As a result, its specific strength (strength/specific gravity) is two to three times that of alloy steel, so that it can be designed to meet the requirements of various types of piping to meet the requirements of internal and external pressure. For single heavy glass steel pipe of the same pipe diameter, there are only 1/2.5 carbon steel pipe (steel coil pipe), 1/3.5 cast iron pipe and 1/8 prestressed reinforced concrete pipe. Therefore, transportation and installation are very convenient. The length of each section of glass fiber steel pipe is 12 meters, which can reduce the joint by two-thirds compared with the concrete pipe. Its socket connection method is quick and easy to install, which reduces the hoisting cost and greatly improves the installation speed.

 

5. Small frictional resistance and high conveying capacity

The inner wall of glass steel tube is very smooth with little roughness and friction. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014 and cast iron pipe is 0. Therefore, glass steel tube can significantly reduce fluid pressure loss along the way and improve conveying capacity. Therefore, significant economic benefits can be obtained: at the same time of conveying capacity, the project can choose the fiberglass pipe with small internal diameter, thus reducing the one-time project investment; With the same inner diameter pipe, the GFRP pipe can reduce the pressure loss and save the pumping cost compared with other materials. In addition, the FRP pipe can shorten the pumping time and reduce long-term operation costs.

 

6. Good insulation of electric heat

Non-conductors are glass fiber reinforced plastic, pipe of electric insulation, insulation resistance in Ω. 1012-1012 cm, the most adapt to use in power transmission, telecommunications line concentration areas and more minefields FRP heat transfer coefficient is small, only 0.23, is five over one thousand of the steel, pipe heat preservation performance.

 

7. Good abrasion resistance

The water containing a lot of mud and sand was put into the pipe for the effect comparison test of rotary wear. After 3 million rotations, the wear depth of the inner wall of the tube was as follows: 0.53mm for the tar and enamel coated steel tube, 0.52mm for the epoxy resin and tar coated steel tube, and 0.21mm for the glass tube after surface hardening treatment. This FRP has good wear resistance.

 

8. Low maintenance cost

Due to the corrosion resistance, abrasion resistance, frost resistance and pollution resistance, the project does not need to carry out anti-rust, anti-pollution, insulation, thermal insulation and other measures and maintenance. There is no need to do cathodic protection to buried pipe, which can save project maintenance cost more than 70%.

 

Good designability

The glass steel tube can be designed and manufactured into different pressure classes and stiffness classes according to the user's specific requirements, such as different flow rates, different pressures, different buried depth and loading conditions.

 

10. Long service life and good comprehensive benefits

The laboratory simulation shows that the service life of FRP pipe can be over 50 years. Comprehensive benefit refers to the long-term nature formed by various factors, such as construction investment, installation and maintenance costs, service life, energy saving and steel saving, etc. The comprehensive benefit of FRP pipes is desirable, especially the larger the pipe diameter, the lower the cost. When further consideration is given to the long service life of buried pipes without annual overhaul, the comprehensive benefits are good.
