FRP Sand Pipe
Product Features ◎ Excellent mechanical properties FRP pipes have a small specific gravity (1.8 ~ 2.1g / ㎝3), high strength (≥300MPa), and their specific strength is much greater than that of steel pipes and cast iron pipes. The resin mortar is added in the middle layer of the pipe wall, which greatly improves The stiffness of the pipeline is suitable for laying in various soil environments and the sea floor.
◎ Excellent hydraulic performance The inner surface of the glass fiber reinforced plastic pipeline is very smooth and the friction resistance is small (n≤0.0084), which can significantly reduce the pressure loss along the flow and increase the flow rate. Under the same flow rate, a smaller pipe diameter or power can be selected. Small delivery pump, which reduces the initial investment in the project and saves energy consumption (reducing operating costs).
◎ Good designability and wide range of application. FRP pipes with different pressure levels and special properties can be made by changing the material selection, winding angle and the design of the layer to meet different working pressure, medium, stiffness (or embedding depth) requirements. .
◎ Anti-fouling, non-toxic and smooth inner wall, no scaling, no breeding of algae and other microorganisms, no secondary pollution to water quality. Pipes made from selected food-grade resins can be used to transport drinking water.
◎ Few joints, good tightness. The length of a single FRP pipe is generally 12 meters, and the socket is connected with double "O" seals. Each interface can be tested for pressure and reliable sealing.
◎ Light weight, easy to transport and install. FRP sand-filled pipes occupy only 1/4 of ductile iron pipes of the same specification and length, and 1/10 of cement pipes. Convenient transportation and loading, high installation efficiency and low cost.
| Title: FRP Pipe Laying |
| Brief introduction: 1. The bottom of the trench of the glass fiber reinforced plastic pipe is uneven, and there are sharp hard objects such as hard soil blocks and stones blocking the pipeline. Generally speaking, the trenches in low-lying areas are all mechanically excavated. Due to the low terrain, the bottom of the trench is wet or watered, and there is a high possibility of hard objects, mainly hard objects such as gravel, bricks and obstacle pipelines. In particular, there is a large amount of water on the pipe trench. When these hard objects exist below the water surface, it is not easy to find them. After the glass fiber reinforced plastic pipe is directly backfilled after the installation on the water surface, the glass fiber reinforced plastic pipe is directly pressed on the hard object. It may not be damaged due to the looseness of the backfill soil in a short time, but due to the subsidence and compaction of the backfill soil, after the pipeline is put into production, the pipeline The internal pressure of the pipe and the internal liquid flow cause micro-vibration of the pipeline. With the increase of time, the point load caused by the hard object on the glass fiber reinforced plastic pipe becomes larger and larger, and the point where the glass fiber reinforced plastic is affected by the hard object will be damaged. In addition, the unevenness of the bottom of the trench will cause uneven force on the pipeline, back to ... [ Detail ] |
