In recent years, bwfrp pipeline is particularly eye-catching, which has become the black horse to break the application market of traditional pipeline products.
As a new material product, bwfrp pipe is unknown to many people. So what is bwfrp?
Bwfrp pipe uses alkali free glass fiber, its main component is silica (quartz sand); while the resin used is mainly unsaturated polyester resin or epoxy resin, all raw materials meet the environmental requirements.
What advantages does it have that you can't imagine?
Bwfrp pipeline advantages
1. High ring stiffness: bwfrp pipes are formed by interlacing and pultrusion of high-performance fiber horizontally and longitudinally, which can improve the ring stiffness of pipes from the physical structure and resist the damage caused by external heavy pressure and foundation settlement. 2. Strong tensile resistance: the braiding angle of bwfrp pipe reaches 120 ° and adopts the inner and outer three-layer braiding process, which has high tensile strength and flexibility compared with traditional pipes. 3. High insulation: excellent alkali free glass fiber and high-performance unsaturated polyester resin are selected for molding under high pressure. The density of bwfrp pipe is 35% higher than that of traditional pipe, with no bubble and high insulation. 4. Good heat and water resistance: bwfrp pipe is extruded under high temperature and high pressure, with high density and excellent water resistance. It adopts high-performance unsaturated polyester resin and non alkali glass fiber raw materials, with higher acid and alkali resistance than traditional pipes. 5. Excellent thermal conductivity: bwfrp pipe has the thinnest wall, excellent thermal conductivity, better carrying capacity and lower electrical loss under the same ring stiffness, which can enhance the service life of the cable. 6. Smooth inner wall: the inner wall of the pipe is smooth, and the force is convenient to pass through the cable, so as to reduce the thread resistance. Rubber sealing rings are installed at the head and tail of the joint to adapt to thermal expansion and cold contraction and effectively prevent sediment intrusion. 7、 Excellent flame retardant performance: BWFRP pipeline has excellent flame retardant performance, oxygen index is more than 28, which exceeds the national standard. When the pipeline is burned in case of fire, it will not be ignited at all. 8. Easy to transport and install: bwfrp pipeline adopts straight connection mode, with lighter weight under the same wall thickness, reducing transportation pressure, convenient installation and greatly shortening construction period. At the same time, avoid the long exposure time of road excavation, and affect the urban traffic order. 9. High and low temperature resistance: bwfrp pipeline has frost resistance and high temperature resistance, which can adapt to harsh environment. Bwfrp pipeline will not be damaged or deformed under extreme temperature of - 50 ℃ - 200 ℃, and still has high quality, good toughness and high strength. 10. Safety and environmental protection: the main raw materials of bwfrp pipeline come from quartz (stone). The raw materials extracted from stone return to the underground, which completely conform to the natural law and pass the strict environmental protection testing standards of the state and the European Union.
