FRP pipe (reinforced), manufactured by the full set of latest equipment imported from Italy after continuous twining and vibration, is a composite material with resin and glass fiber as major raw material instead of cement and water in traditional cement concrete, condensed by quartz sand of different grain compositions with fillers such as polyester resin. By bonding many different materials, resin renders resin concrete with greater elasticity, higher safety, embrittlement resistance as well as corrosion resistance. Compared with traditional fixed-length pipe jacking, it is a new substitute product for FRP jacking pipe for its higher strength, thicker wall, better safety and reliability.
The production and construction of products strictly implement international national standards.

Other advantages High dimension precision- no oval, close connection and maintenance tracking;Parallel pipe ends in straight-line distance, jacking force is evenly distributed;Steel sleeve- permanent endurance during jacking; Less risk relating to point load and partial fracture; Smooth, flat and un-perforated pipeline external surface- reduced surface friction and transient load at the time of startup after long-time interruption
Excellent water pressure characteristics Smooth inner wall; Manning discharge coefficient (n) 0.009; Less frictional loss and higher flow; Least clay accumulation and lower cleaning expense; Excellent abrasion resistance
High-strength High pressure resistance (not less than 80Mpa); Possible to cope with long-distance and complex terrain with higher jacking force
Excellent connection system Water tightness up to 2.5kg/cm2; Tight and highly efficient connection, free from leakage; Convenient connection and reduced installation time.
Advanced pipeline design technology High-performance standard: ASTM, DIN Consistent high quality and product performance around the world
Corrosion-resistant material Corrosion resistant ph1.0—10, expected service life up to 100 years; No need for liner, external protection layer, cathode anticorrosion or other anti-corrosion protection; Lower maintenance cost; Water pressure characteristics is basically constant, independent from time change.
Bind closely with polyester resin and polymer evenly, sand and glass steel pipe jacking (strong) composition of particularity, therefore, has excellent mechanical properties, can adapt to PH1.0 10 different working environment by changing the resin grades can also apply different corrosive medium, the service life of 50 in 100, does not need to do emergency anticorrosion, low maintenance cost
Pipe jacking is standard connector for a fully embedded into the wall of the stainless steel or FRP sleeve, fitted with a rubber seal (type O F the water expansion aprons), in order to ensure no leakage In direct buried application, using glass fiber reinforced plastic sleeve, forming a socket connection system made in advance of the sleeve, make the pipe connection simple quick pipe can be cut into any length, and connect with the sleeve
