Metal level, the second elastic layer, the second resin sand pulp layer, fibre-reinforced plastics outer layer are socketed successively, the
One resin sand pulp layer is that the resin sand slurry spirally winding with sand grains is at fibre-reinforced plastics internal layer
Outer surface is formed, and the second resin sand pulp layer is that the resin sand slurry spirally winding with sand grains is in fiber reinforcement
The inner surface of composite plastic outer layer is formed, and metal level is made up of layers of copper, nickel dam, aluminium lamination from inside to outside, layers of copper
With at the faying face of nickel dam both phase counterdiffusion, phase counterdiffusion both at nickel dam and the faying face of aluminium lamination.
Preferably, in metal level, copper layer thickness: nickel layer thickness: aluminum layer thickness is 1:(0.01-0.03):
(1-6)。
Preferably, the first resin sand pulp layer and the second resin sand pulp layer medium sand grain are respectively provided with sizes.
Preferably, the first elastic layer thickness: metal layer thickness: the second elastic layer thickness is
(0.0015-0.0025): 1:(0.0015-0.0025).
In above-mentioned multi-layered composite pipe, fibre-reinforced plastics internal layer and fibre-reinforced plastics outer layer are permissible
Good corrosion resistance, the first resin sand pulp layer and the second resin is provided for the inner surface of multiple tube and outer surface
Screed can improve the resistance to stress ability of multiple tube tube axial direction, and metal level makes the mechanical strength of multiple tube
Get a promotion, the first elastic layer, the second elastic layer can promote respectively the first resin sand pulp layer and metal level it
Between, the binding ability under thermal expansion repeatedly between metal level and Article 2 resin sand pulp layer；Fiber reinforcement is multiple
Close inner plastic and the first elastic layer multiple to parcel, the second elastic layer and the fiber reinforcement of the first resin sand pulp layer
Close the plastic outer layer parcel to the second resin sand pulp layer, can effectively prevent the first resin sand pulp layer and the second tree
In fat screed, sand grains comes off；Metal level is designed as layers of copper, nickel dam, aluminium lamination three are composited, and one
Aspect can pass through aluminium lamination, is keeping on the basis of multiple tube mechanical performance, reduce whole multiple tube weight and
Cost, on the other hand, can realize the good combination of layers of copper and aluminium lamination by nickel dam transition, and layers of copper and nickel
Phase counterdiffusion both at the faying face of layer, both at nickel dam and the faying face of aluminium lamination, this level of phase counterdiffusion is tied
Structure can promote the integraty of whole metal level further, thus promotes the ruggedness of multiple tube；Therefore, may be used
So that the anti-pressure ability of multiple tube is good and corrosion resistance excellent, and ruggedness is good.

Detailed description of the invention
As depicted in figs. 1 and 2, Fig. 1 is the structural representation of a kind of multi-layered composite pipe that the present invention proposes；
Fig. 2 is the partial schematic sectional view of Fig. 1.
With reference to Fig. 1 and combine Fig. 2, in one embodiment, a kind of multi-layered composite pipe that the present invention proposes, bag
Include fibre-reinforced plastics internal layer the 1, first resin sand pulp layer the 2, first elastic layer 3, metal level 4,
Two elastic layer the 5, second resin sand pulp layer 6, fibre-reinforced plastics outer layer 7, from inside to outside, fiber increases
Strong composite plastic internal layer the 1, first resin sand pulp layer the 2, first elastic layer 3, metal level the 4, second elastic layer 5,
Second resin sand pulp layer 6, fibre-reinforced plastics outer layer 7 are socketed successively, and the first resin sand pulp layer 2 is tool
The resin sand slurry spirally winding having sand grains is formed at the outer surface of fibre-reinforced plastics internal layer 1, the
Two resin sand pulp layer 6 are that the resin sand slurry spirally winding with sand grains is at fibre-reinforced plastics outer layer 7
Inner surface formed；Under above-mentioned design, fibre-reinforced plastics internal layer 1 and fibre-reinforced plastics
Outer layer 7 can be the inner surface of multiple tube and outer surface provides good corrosion resistance, the first resin sand pulp layer 2
With the resistance to stress ability that the second resin sand pulp layer 6 can improve multiple tube tube axial direction, metal level 4 makes multiple
The mechanical strength closing pipe gets a promotion, and first elastic layer the 3, second elastic layer 5 can promote the first resin respectively
Between screed 2 and metal level 4, between metal level 4 and Article 2 resin sand pulp layer under thermal expansion repeatedly
Binding ability；Fibre-reinforced plastics internal layer 1 and the first elastic layer 3 are to the first resin sand pulp layer 2
