Abstract
The utility model discloses an autologous flange type steel mesh reinforced plastic pressure pipe which comprises a pipe wall in which a steel mesh is clamped. The autologous flange type steel mesh reinforced plastic pressure pipe is characterized in that two ends of the pipe are provided with flanges which are molded into a whole, wherein the flange of at least one end is provided with a ring-shaped slot. The autologous flange type steel mesh reinforced plastic pressure pipe has the benefits that the pipe ends are provided with flanges which are molded into a whole, moreover, the flange at one end is provided with the ring-shaped slot which is embedded with a sealing ring, thereby facilitating pipeline construction and connection; and the production cost can be effectively lowered by using flame for heating when in manufacture.
Description
Technical field
The utility model relates to plastic pipe, especially a kind of self-flanged steel mesh-reinforced plastic pressure pipe.
Background technique
Steel mesh-reinforced plastic pressure pipe is meant and accompanies the pipeline that steel mesh strengthens in plastic tube wall, uses as the heavy caliber pressure piping usually.Making steel mesh-reinforced plastic pressure pipe can be with reference to existing plastic working method, and existing plastic working method mainly contains following four kinds: extrusion molding, injection moulding, blowing and rotational moulding.
Extrusion molding is continuously shaped, is applicable to make tubing, section bar, sheet material etc.Mould transfixion during extrusion moulding, its shortcoming are to be unsuitable for making heavy caliber pipe, can't form integrated flange at pipe end, after the flange join strength that adds not enough, and extrusion molding production process power consumption is big, cost is more expensive.
Injection moulding is the clearance type moulding, is applicable to make the little plastic article of all lengths, comprises pipe fitting that pipeline is used etc., and its shortcoming is the mould costliness, and power consumption is big, and cost is more expensive.
Blow moulding can be the moulding in gap, for example makes container etc., also can be continuous moulding, for example makes film products.It is applicable to makes the thin plastic article of wall thickness.
The rotational moulding method is the gap moulding, is used to produce large-scale special-shaped plastic article, as water tank, inspection shaft, yacht etc., also can make pipeline, and the advantage of rotational moulding method is to use flame heating, and cost is lower.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, and the manufacture method and the mould of the lower self-flanged steel mesh-reinforced plastic pressure pipe of a kind of fabricating cost is provided.
The technical solution of the utility model is as follows:
A kind of self-flanged steel mesh-reinforced plastic pressure pipe comprises tube wall, accompanies steel mesh in tube wall, it is characterized in that, at the pipe two ends integrated flange is arranged, and on the flange of at least one end circular groove is arranged therein.
Supplementary technology scheme of the present utility model is as follows:
Preferably, described plastic tape material is identical with the plastic raw material material of making pipeline.
Preferably, in flange, be filled with the steel mesh of ring-type.
The beneficial effects of the utility model are: at pipe end integrated flange is arranged, and an end flange is provided with sealing-ring-embedded annular groove therein, has made things convenient for the pipeline construction connection; Mould has internal mold; Mould rotates during moulding; Because internal mold is arranged, can make pipeline that steel mesh strengthens, also can make other goods of inner wall smooth, outer wall abnormal shape; The caliber scope in the steel mesh-reinforced plastic pressure pipe road that can make is wide, can pipeline do not have seam to very big by very little, and inner wall smooth, good integrity, resistance to water-flow is little; Because mould shaft is not moved, in mould rotates, axle can be made hollowly, and can heat internal mold with flame by hollow shaft; Because use steel mesh to strengthen, plastic pipe intensity is improved, cost reduces; Use flame heating can remove the required a large amount of electric energy of electric heating from, obviously reduced cost of production; Pipeline yield rate height, the manufacturing efficiency height.
