FRP prestressed concrete cylinder pipe (FPCCP)
1, safe and reliable design
FPCCP designed in accordance with AWWA CSO4 and AWWA M9 implementation, design process, the use of limit state criteria, elastic and ultimate strength limit state criteria guidelines, the pre-pressure, internal pressure and external load rational combination, combined with the wall of the elastic deformation and inelastic deformation give full play to the tensile steel, concrete compressive strength, FRP chemical resistant properties, the safe limit of tensile and compressive stress of concrete, design engineers can be based on the actual situation of the pipeline the most economical and reliable pipe design.
2, the joint has good resistance to leakage of
FPCCP joint use ofthe "O" rubber ring seal; its socket and the socket ring ring for glass fiber reinforced composite cylinders, for the self-socket joints, with the installation of self-positioning effect; jack groove embedded with a special steel, rubber ring rubber seal groove in accordance with sections such as design, installation in the groove, installed after the tvvo-way squeeze by the rubber ring to form a good seal strength, ensure anti-leakage performance ofthe pipe.
3, excellent corrosion resistance
Constitute FPCCP all concrete and steel are wrapped in fiberglass, steel and glass socket composite steel tube,
thereby FPCCP has good corrosion resistance. Sea transportation to meet delivery and various chemical media.
4, hydraulic flow resistance
FPCCP pipe wall of glass fiber reinforced resin-rich surface roughness up to 0.0084, the inner surface smooth, easy scaling, to ensure consistent flow pipeline.
5, the installation of high efliciency
FPCCP pipe length is usually 6 m / root and 12 m / root, the installation quick and easy. FPCCP pipe pipe socket
though, but uniform diameter, without additional processing base without mortar joints perfusion, improved
installation efficiency.
6, the flexible joints on the basis of adaptability
FPCCP joints can rotate a certain angle, with a strong ability to resist uneven settlement of foundation do not ask, you can adapt to the complex geological conditions.
7, strong earthquake
FPCCP pipe composite of fiberglass, concrete, steel tube, and prestressed steel wire, socket joints using FRP composite steel, full glass, steel, flexibility and steel toughness, FPCCP tube with excellent seismic performance, the strong earthquake can maintain intact lossless.
8, FPCCP supporting pipe fittings complete
FPCCP great flexibility to provide different forms of the supporting tube FPCCP to meet the environmental requirements of different projects.
9, engineering adaptability
FPCCP by the glass, steel, concrete, steel tube, and prestressed steel composite, can adapt to a variety of construction techniques can be used for direct burial, jacking, inverted siphon and other construction technology FRP smooth surface suitable for pipe jacking process.
1 0, long life
FPCCP use of fiberglass and steel tube impermeability the use of glass and steel wire for prestressed steel tube to protect it from the external environment of corrosion, the useful life of 50 years.
1 1, excellent engineering economy
FPCCP excellent mechanical properties, lower requirements for foundation and backfill, reducing construction costs, while glass, steel for steel protection, no interface, the pouring of concrete and steel tube cathodic protection, engineering, economic good.
12, low maintenance costs
FPCCP glass composite pipe, concrete pipe and pipe the advantages of excellent mechanical properties, does not require maintenance during the operation, maintenance costs are lower
