Metal Reinforced pipe ( MRP ), is also known metal reinforced polyethylene ( PE ) spiral corrugated pipe for underground sewer metal reinforced polyethylene spiral corrugated pipe and metal reinforced plastic pipe.
MRP. based on the overseas advanced technique for metal and plastic tubing compounding. is a kind of PE metal compounding wall tube. whose Invert is entwining structured. The wave structure helps to maximize the high elasticity modulus of steel to make the pipe of high ring stiffness. The PE with stable chemical property on both Internal and external layers makes the pipe corrosion resistant and abrasion-resistant , ensuring its longevity service.The low roughness coefficent of its Invert guarantees the higher carrying capacity. The fistulous and wave structure makes it light. strongly connected and convenient for construction it is a kind of flexible pipe. with high earth deposition resistance. plastic , glue and steel tightly connected with pressure and corrosion resistance. high whole performance.
As a new kind of plastic pipe MRP. with its high ring stiffness. is finely applicable to sewer work. such as rainfall sewage and wastewater drain-down system. It could be described as an Industrial innovation to replace the pure - plastic pipe With MRP.
1.Excellent wear resistance- - -low pipe friction coefficient,small resistance, rapid speed for medium , drainage and sewerage transmission.
2.High ring stiffness- - - could be achieved SN12.5, SN16.
3.Light weight- - - only 1/8 weighs of concrete pipe and 2/3 weighs of traditional winding plastic structural pipe.under the same specifications , convenient transportation and construction, without large equipment .
4.Strong pressure assistance- - - the pipe has the helix shape, when hit by external force, it is easy to be recovery.and not easy be broke under the stretch squeeze by adverse geological environment as earthquake and water marsh.
5.Cold resistance- - - pipes wont break and leak as freeze .
6.Aging resistance - - - pipe could be used for more than 50 years at 20 degrees .
7.Corrosion resistance - - - the material ( PE ) would not be corrosive by acid and oil.
MRP is a kind o entwining structured wall tube with the substrate ( Internal and external layers ) made or PE and adhesive plastic-metal compounding coated on the surface. MRP, whose outer substrate is made of PE, surface coated with high performance adhesive resin and main bracing structure ( steel waveform structure ) gained through filament winding. is an Integral pipe after special processing. The pipe-wall is composed of three layers ,namely ,the PE tube of solid wall,circular waveform metal reinforcement and PE layer from the inside out.
