What fields are the performance characteristics of FRP sand-filled pipes mainly used in?
Scope of application:
1. Municipal drainage and sewage pipeline system engineering.
2. Buried drainage and sewage in apartments and residential quarters.
3. Pre-buried pipelines of expressways, underground water seepage network of golf courses.
4. Water conservancy projects such as farmland water conservancy irrigation, water supply and drainage, etc.
5. Chemical industry and mine are used for fluid transportation and ventilation, etc.
6. Protective casing of underground pipelines and communication cable casings, etc.
The performance characteristics of glass fiber reinforced plastic sand pipe
Unique structure, high strength, smooth inner wall, low friction resistance, large circulation, no need to make concrete foundation, light weight, convenient transportation and installation, fast construction; rubber ring socket connection, reliable method, easy to ensure construction quality; flexible interface . Strong resistance to uneven settlement; good anti-leakage effect, resistant to erosion by various chemical media; no scaling in the pipe, basically no need to dredge, and the service life of the buried ground is more than 50 years.
Physical properties Project unit index Impact strength (TIR) ≤10% Ring stiffness S1 grade KN/㎡≥4S2 grade KN/㎡≥8 Ring flexibility The sample is smooth, no reverse bending and no breakage, and the two wall elements are separated from the oven test No splitting, no cracking Continuous sealing test No leakage Dichloromethane soaks the inner and outer walls without separation, the inner and outer surface changes are not inferior to 4L Creep rate ≤ 2.5.
