Good Quality MPP Power Cable Sheath - FRP Fiberglass Power Pipes Power Cable Protection Pipes – Yingzhong

Production Description

● Good corrosion resistance. Since the main raw materials of FRP are composed of unsaturated polyester resin and glass fiber with high polymer content, it can effectively resist the corrosion of acids, alkalis, salts and other media, as well as untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. The erosion, in general, can keep the pipeline running for a long time.
● Good anti-aging performance and heat resistance. FRP pipes can be used for a long time in the temperature range of -40℃～70℃, and high temperature resistant resin with good formula can also work normally at temperatures above 200℃. For pipes that have been used in the open air for a long time, ultraviolet absorbers are added to the outer surface to reduce the radiation of ultraviolet rays to the pipes and delay the aging of the FRP pipes.
● Good frost resistance. Under minus 20℃, the tube will not freeze after freezing.
● Light weight, high strength and convenient transportation. FRP is not only light in weight, high in strength, strong in plasticity, convenient in transportation and installation, but also easy to install various branch pipes, and the installation technology is simple.
● Good hydraulic conditions. The inner wall is smooth, the conveying capacity is strong, no scaling, no rust, and small water resistance.
● Good designability. FRP pipes can be designed and manufactured into pipes with different pressure levels and stiffness levels according to various specific requirements of users, such as different flow rates, different pressures, different burial depths and load conditions.
● Low maintenance cost. Due to the above-mentioned properties of corrosion resistance, anti-wear, anti-freeze and anti-fouling, the project does not need to carry out measures and maintenance such as anti-rust, anti-fouling, insulation and heat preservation. There is no need for cathodic protection for buried pipes, which can save engineering maintenance costs by more than 70%.
● Good abrasion resistance. The water containing a large amount of mud, sand and gravel is put into the pipe to carry out the comparative test of the effect of rotating wear. After 3 million rotations, the wear depth of the inner wall of the detection tube is as follows: 0.53mm for the steel tube coated with tar and enamel, 0.52mm for the steel tube coated with epoxy resin and tar, and 0.52mm for the steel tube coated with surface hardening. 0.21mm. As a result, the anti-wear performance of FRP is good.
● Good electrical and thermal insulation. FRP is a non-conductor, the electrical insulation of the pipeline is excellent, the insulation resistance is 1012 ~ 1015Ω.cm, the heat transfer coefficient of FRP used in power transmission, telecommunication line dense areas and multi-mine areas is very small, only 0.23, which is one thousandth of steel Fifth, the thermal insulation performance of the pipeline is excellent.
● Small friction resistance and high conveying capacity. The inner wall of the FRP pipe is very smooth, and the roughness and frictional resistance are very small. The roughness coefficient is 0.0084, while the n value of the concrete pipe is 0.014 and that of the cast iron pipe is 0.013. Therefore, the FRP pipe can significantly reduce the fluid pressure loss along the way and improve the conveying capacity.
● Fiberglass piping reduces pumping time and long-term operating costs.
