Abstract

A wear-resistant cast stone glass fiber reinforced plastic composite pipeline is composed of a wear-resistant inner layer and a glass fiber reinforced plastic reinforcing layer fitted at the outer side of the wear-resistant inner layer; and the glass fiber reinforced plastic reinforcing layer is formed from unsaturated polyester resin-immersed glass fiber cloth by winding. The wear-resistant cast stone glass fiber reinforced plastic composite pipeline provided by the utility model is advantageous in that the wearability is improved by 10-15 times compared with a glass fiber reinforced plastic pipeline, thus the requirement of solid delivery can be satisfied; the cost is 40-50% lower than that of a cast stone steel pipe, and the weight is 60-70% lower than that of the cast stone steel pipe; the advantages of the glass fiber reinforced plastic pipeline are combined, so that processing such as rust prevention, fouling prevention, electrical insulation, thermal insulation, etc. and overhauling are not required, as a result, the engineering maintenance cost is greatly reduced; and the compression strength can reach 0.2-2.0MPa, which is 1.5-2 times of that of the cast stone steel pipe of the same type.

Description

Wear-resisting type cast stone glass fibre reinforced plastic composite pipe

Technical field

The utility model belongs to the conveyance conduit technical field, particularly relates to a kind of wear-resisting type cast stone glass fibre reinforced plastic composite pipe.

Background technique

Glass fibre reinforced plastic composite pipe commonly used at present can only be used for conveyance fluid; But can not conveying solid substance (like coal, limestone and various ores etc.), because solid is more much bigger than fluid to the wearing and tearing of pipeline, and glass fibre reinforced plastic composite pipe exactly wears no resistance; So conveying solid substance adopts the cast stone steel pipe more in the prior art; The internal layer of cast stone steel pipe adopts the cast stone material, is mainly used in wear-resistantly, and outer compound steel pipe then is used for moulding; Though poor plasticity when this cast stone steel pipe can solve that common steel tube wears no resistance and adopt cast stone merely, therefore can't process defective such as pipeline, still there are shortcomings such as weight is big, cost height in the cast stone steel pipe.

Summary of the invention

In order to address the above problem, the purpose of the utility model is to provide a kind of cost low and lightweight wear-resisting type cast stone glass fibre reinforced plastic composite pipe.

In order to achieve the above object, the wear-resisting type cast stone glass fibre reinforced plastic composite pipe that provides of the utility model is made up of wear resistant inner layer and the glass fibre reinforced plastics enhancement layer that is enclosed within the wear resistant inner layer outside; Wherein wear resistant inner layer is made up of with the weight ratio of 3-7: 23-27: 68-72 cast stone sand, grayish green rock dust and high tenacity unsaturated polyester resin; The glass fibre reinforced plastics enhancement layer is entwined by the glass fiber cloth that is soaked with unsaturated polyester resin.

Described wear resistant inner layer is 1-100: 1-100 with the thickness ratio of glass fibre reinforced plastics enhancement layer.

The wear-resisting type cast stone glass fibre reinforced plastic composite pipe that the utility model provides has following advantage:

1, the wear resistance of this pipeline has improved 10-15 doubly than GRP pipe, therefore can satisfy the requirement of conveying solid substance fully, has broken the narrow limitation that GRP pipe can only be used for conveyance fluid;

2, the cost of this pipeline is than the low 40%-50% of cast stone steel pipe, the light 60%-70% of weight ratio cast stone steel pipe;

3, this pipeline has combined the advantage of GRP pipe, need not carry out in the construction that antirust, antifouling, insulation, insulation etc. are handled and maintenance, therefore can reduce the engineering maintenance expense greatly;

4, compressive strength of the present invention can reach 0.2-2.0MPa, is 1.5-2 times of same model cast stone steel pipe.
