Abstract

The utility model relates to a pipe, wherein, the pipe wall of which is provided with two layers. The utility model comprises a cement pipe. The surface of an inner wall of the cement pipe is provided with a PVC plastic layer. The composite pipe provided by the utility model has the advantages of good self-cleanness, little running resistance, good corrosion resistance, high anti-compression strength and low cost.

Description

The high-strength compound pipe

The utility model relates to rigid pipe, and specifically a kind of tube wall is double-deck pipe.

Its inwall of the common cement pipe cement pipe of glass fibre (or contain) is smooth inadequately, and self-cleaning is not good, and the running resistance when carrying siccative, the slurry that contains solid, lotion is bigger, the easy incrustation of inwall, and the seepage phenomenon is easily arranged.All not good for its self-cleaning of cast iron tube and corrosion resistance.And its self-cleaning of pipeline, corrosion resistance, the leakage proof made by PVC fully are all better, but material is more crisp, the critical external compressive resistance ability is lower, and cost is higher.

The purpose of this utility model is to provide a kind of composite pipe, its self-cleaning capable property and good corrosion resistance, and cost is lower.

For achieving the above object, the high-strength compound pipe that the utility model provides includes cement pipe, is provided with the PVC plastic layer on the cement pipe inner wall surface, promptly is lined with a PVC plastic tube in the cement pipe.

The smooth surface of PVC plastics, and have acid-and base-resisting performance preferably, and the compressive strength of cement pipe is better.Therefore, the high-strength compound pipe that the utility model provides has that self-cleaning is good, running resistance is little, good corrosion resistance, characteristics that compressive strength is high, and cost is lower.

Description of drawings:

Accompanying drawing is the utility model one embodiment's a structural drawing.

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to accompanying drawing, this composite pipe is made of cement pipe 1 and the PVC plastic layer 2 that is lining on its internal surface, promptly is lined with a PVC plastic tube in the cement pipe, and the cohesive force by cement in the working process between the two bonds.The thickness of PVC plastic layer is 0.5-2.5mm.The step of making this composite pipe is: the prefabricated PVC plastic tube of elder generation, with of internal layer and the cement pipe mould outer combination of PVC plastic tube as the cement pipe mould, constitute the cement pipe mould, the cement pipe of casting then, the cement pipe casting is finished after the certain hour drying, remove cement pipe mould skin, i.e. the cost multiple tube.

The materials of the above cement pipe adopt the prescription of existing known portland cement pipe, can have following two kinds: 1, cement, waste residue, glass fibre; 2, magnesium chloride, magnesium oxide, waste residue, glass fibre.

The composite pipe that the utility model provides can prevent inwall incrustation effectively, and acid-and base-resisting is preferably arranged, and can be widely used in fields such as oil, chemical industry, mine, electric industry, urban construction, hydraulic engineering and discharge of industrial wastes.

Claims

1, a kind of high-strength compound pipe comprises cement pipe (1), it is characterized in that: be provided with PVC plastic layer (2) on cement pipe (1) inner wall surface.
