Fiberglass sand filled pipeline
- DESCRIPTION
-
- Commodity name: Fiberglass sand filled pipeline
Fiberglass sand filled pipes have good corrosion resistance, long service life, excellent mechanical properties, good designability, wide adaptability, anti fouling, non-toxic, few joints, good sealing, light weight, and are easy to transport and install. Resistance coefficient: cement pipe: f=0.00232; Steel pipe: f=0.00179; Sandwich tube: f=0.000915
Features:
1. Light weight and high strength: the specific gravity of FRP sand inclusion pipe is 1.65~2.4. For the unit length weight of the same pipe diameter, only 1/3 of carbon steel, only 1/5 of cast iron pipe, and 1/10 of prestressed pipe, which reduces the hoisting cost and improves the installation speed in construction.
2. Good hydraulic characteristics: This characteristic is particularly prominent in the field of water supply and drainage, and its hydraulic characteristics are good.
(1) It can save the cost of pumping pipe network; (2) Reduce the size of the pipe diameter; (3) shorten the pumping time; (4) Long-term water transportation does not scale, no need to clean pollution, so that the water quality is not subject to secondary pollution.
3. Good water resistance and corrosion resistance: the FRP sand inclusion pipeline has excellent corrosion resistance, which reduces the corrosion cost and prolongs the service life; At the same time, because it does not rust, the water quality is not subject to secondary pollution, and it can also be used to transport sewage, mud, seawater and other media.
4. Pressure-resistant: design and manufacture pipes and pipe fittings according to the pressure required by the process, and carry out the hydrostatic test at 1.5 times the pressure required by the process.
5. The interface has good sealing, no leakage, no rupture, increases the safety and reliability of water supply, is non-toxic, and can be used to transport drinking water.
