r B _ Corrosion-resistant R pipes can resist corrosion from acid, alkali, salt, seawater, untreated sewage, corrosive soil or groundwater, and many chemical fluids.
The temperature range of R pipes with good heat and frost resistance is generally between ℃ and ℃. If special resin is used first, the service temperature can reach higher.
Light weight and high strength, easy to transport and install. The specific gravity of R pipe is. Compared with other material pipes of the same pressure and diameter, the weight per unit length of R pipe is approximately equal to that of steel pipe, so it is very convenient to transport and install. Each length of R pipe Reachable and quick and easy to install. In addition, the welding and anti-rust and anti-corrosion treatments required for installing steel pipes can be eliminated.
Small friction resistance, high transportation capacity. The inner surface of the R pipe is very smooth, with a small roughness coefficient. The water conservancy coefficient can be maintained within the range for a long time. After testing, the water flow friction loss coefficient is found to be, which can significantly reduce the fluid along the process. Pressure loss increases the conveying capacity above.
Good electrical insulation. R is a non-conductor. The insulation of pipes is good. It is most suitable for use in areas with dense transmission and telecommunication lines and areas with many mines. The heat transfer coefficient of R pipes is very small/°C, so the pipes have good thermal insulation. Less heat loss.
Rust-free Since FRP pipes are made of non-metallic materials, resin and glass fiber, they will not rust whether they are in use or idle, so there is no need for anti-rust removal. Rust treatment. Strong designability. According to the specific usage conditions, the specific performance and shape of the wound fiberglass reinforced plastic pipe can be designed
① The winding angle during winding can be designed so that the pipe has different longitudinal/circular strength distribution
②The wall thickness of the pipe can be designed so that the pipe can withstand different internal and external pressures
③The materials can be designed to achieve different corrosion resistance purposes, flame retardant purposes, dielectric purposes, etc.
④Can be Designed in a head-awarding manner, it is suitable for different installation conditions to improve the installation speed of the project.
Various connection methods: There are many flexible ways to wind FRP pipe joints, including flat end butt joints, loop flange connections, socket glue joints, ring connections with locking devices, threaded connections, etc. Joints can be flexibly selected according to specific construction conditions. method, thus improving the reliability of the project.
