1. Corrosion resistant FRP pipes resist acid, alkali, salt, sea water, untreated sewage, corrosive soil or groundwater, and the corrosion of numerous chemical fluids.
2, good frost resistance FRP heat pipe temperature range between 40 to 80 DEG C, if the first with a special resin use temperature can reach higher.
3, light weight and high strength, convenient transportation and installation of FRP pipe in the proportion of 1.7 to 1.9, compared with other materials with the same diameter, pressure pipe, FRP pipe, weight per unit length is approximately equal to 30% of steel, so the transportation is very convenient for installation, FRP pipeline each length up to 12M, fast and simple installation. In addition, the welding, rust prevention and anticorrosion treatment of the steel pipe can be relieved.
4, small friction resistance, high transmission capacity of FRP pipe inner surface is very smooth, the roughness coefficient is small, water coefficient C can be maintained in the range of 145-150 for a long period of time, is obtained by the test the water friction loss coefficient f is 0.000915, can significantly reduce the loss of fluid pressure, increase the transmission capacity of more than 20%.
5, electricity, heat insulation of FRP is a non conductor, pipe insulation, used in power transmission and telecommunication lines and the most concentrated area of CAAC to FRP tube heat transfer coefficient is very small (0.25kcal/m H C), so the pipeline and good insulation, less heat loss.
6, do not rust because of the glass steel pipe is made of nonmetal materials of resin and fiberglass. Therefore, both in use or in the idle process, will not rust, so there is no need for anti rust, rust treatment.
7, the design can be strong, according to the specific use of circumstances, the winding glass fiber reinforced concrete performance and shape of the design:
The winding angle can be designed so that the tube has different longitudinal / annular strength distribution;
The wall thickness can be designed so that the tube can withstand different internal and external pressures;
Thirdly, the material can be designed to achieve different corrosion resistance purposes, flame retardant purposes, dielectric purposes, etc.;
The design of the head way can be applied to different installation conditions so as to improve the installation speed of the project.
8, there are a variety of flexible winding connection, joint FRP pipe mainly includes: butt joint, (loop) flange connection, socket bonding, (with locking device) O ring connection, threaded connections, according to the specific construction conditions, flexible selection of joints, so as to improve the project the reliability of the.
9, repair convenient to maintenance and winding pipe can not rust, scaling, corrosion resistant performance is good, generally do not need maintenance; even if the need for maintenance, because of its light weight, strong maintainability, so it is very convenient for maintenance
