frp pipe
1.Possessing distinguished physics-mechanical properties
2.Corrosion-resistance, long service life
FRP possesses excepotional chemical resistance.The different FRP pipes can be choosen while considering the different medium especially when there are many pipes crossing.
3.Excellent hydraulic characteristics
The hydraulic characteristic of FRP pipe is one of the most important properties.Good hydraulic characteristic means little loss of liquids pressure-head.To do the same job, it is possible to use pumping pipe with smaller diameter, or if installed the same size pipe to obtain savings in investment over the anterior-period of pipeline construction,economizing electricity therefore reduced operational cost.
4.Low installation and maintenance costs
Generally speaking,FRP pipe usually requires no special corrosion-resistant painting;the thermal insulation layer can be thinned without added thermal-dealing;low resume of efficiency with light weight of pipes;long unit FRP pipe with handful joint in the spots,operated easily and quickly.
5.Design flexibility and short period of model-changing
FRP pipe is produced by filament winding in which fibers impregnated with resin are wrapped onto a former mandrel which is withdrawn after resin is cured.The wall of pipe is samdwich that can modulate the physical and chemical properties by change resin system or adopt different pressure-level or some special property.Short period of model-changing is a prominent peculiarity of filament winding composite that other metallic other metallic pipe cannot compete with.
Dont pollute medium
FRP pipe are serriedly jointed and there is no odor,no poison,no impurity peeled off.The pipes produce no bacteria,germ and iron-ion so it will not contaminated the medium conveyed.
Product range
GRP pipes and fittings diameter range starts from 25mm up to 4000mm,Pressure classes are available up to 25 bar and the maximum design temperature is 150 for vinylester resin and 70 for polyester resin.Available jointing systems are the following:
1. Bell and spigot gasket joint is used for underground installation.Bell and spigot gasket joints is a flexible joint that allows an angular deflection,up to 3for certain diameters.For further details please refer to the Zhongfu Lianzhong installation guide for underground installations.
2. 2.Restrained joints used for both aboveground and underground installations.
3. Stiffness Classes & Burial Depth (for underground installations)
GRP pipes and fittings are available in standard classes250 N/m2 ,500N/m2 and 10000N/m2 .Higher stiffness classes are also available depending on the type of application.The burial depth ranges from 1m to 18 meters,depending on the type of application.Backfilling types:For details of backfilling types, please refer to the Zhongfu Lianzhong installation guide for underground pipe systems.
4. Wall thickness and unite weight of GRP pipe with different pressure capacity is shown in table 1.
Applications
GRP pipes and fittings are being used for a wide of applications,underground and aboveground installation, including:
1. Potable Water Trunk Lines
2. Chlorination Systems
3. Seawater cooling systems
4. Effluent/Potable/Brine Water transmission Lines
5. Seawater Intake and Outfall lines
