Description
Technical field
The utility model relates to a kind of multiple tube, and heavy caliber thermoplastic composite tube is used in especially a kind of industry and life, belongs to pipe-line equipment technical field.
Background technique
The large diameter pipeline now using is mainly the plastic tubes such as steel pipe and common PE pipe, steel pipe can meet the occasion that working pressure is relatively high, but steel pipe is in use not corrosion-resistant, can affect working life and the usability of steel pipe, and steel pipe internal layer is easy fouling in the time of conveying medium, affect the mobility of medium.Because the length of steel pipe is fixed, in installation process, to use more joint, installation procedure complexity, expense is high.And common plastic tube, although install and use compared with steel pipe conveniently, its working pressure is low, is only applicable to the conveyance conduit of low pressure, narrow application range.
Model utility content
The purpose of this utility model is: the problem existing for above-mentioned prior art, proposes one simple in structure, the heavy caliber thermoplastic composite tube that working pressure is high.
In order to reach above object, heavy caliber thermoplastic composite tube of the present utility model, its improvements are, described composite pipe body is as a whole, comprises the inner tube, enhancement layer and the outer tube that are bonded together by hot melting way from the inside to the outside.
The utility model further improves, and after described inner tube layer and enhancement layer or described enhancement layer and external tube layer pass through infrared rays or microwave heating melting, bonding is fixing.
The utility model further improves, described enhancement layer has four layers at least, every one deck comprises that at least four by opposite direction and to fix the reinforcing band of helix angle voluble wrapping outside inner tube, and described reinforcing band is made up of the reinforcing fiber of one group of alinement and the polyolefine material being wrapped in outside reinforcing fiber.After the reinforcing band of described adjacent two layers passes through infrared rays or microwave heating melting, bonding is fixing.Described outer tube is coated on outside enhancement layer, and entirety of bonding formation between layers.
It is that the inside nominal diameter of described composite pipe is DN200～DN300 that the utility model further improves.
The utility model has the advantage of: heavy caliber thermoplastic composite tube of the present utility model adopts three-layer composite structure composition, make body can effectively offset radial force in the time bearing interior pressure, avoid body distortion, its bore can reach DN200～DN300, the thermoplasticity reinforced composite pipe of bore maximum up to now, that pipeline has is lightweight, pressure-bearing is high, corrosion-resistant, the life-span long and can coil, the advantage such as easy construction.In a word, the utility model has not only overcome the shortcoming that the large-diameter pipe that now exists in use exists, and this tubular construction is simple, quick and easy for installation, non-maintaining, can be used in that pressure is high, corrosivity requires high occasion.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model embodiment one structural representation.
Fig. 2 is that the A-A of Fig. 1 is to generalized section.
Fig. 3 is the I partial enlarged drawing of Fig. 2.
Fig. 4 is the structural representation of reinforcing band in the utility model.
Embodiment
Embodiment one
The heavy caliber thermoplastic composite tube of the present embodiment, as shown in Figure 1 to Figure 3, composite pipe body is as a whole for its structure, adopts three-layer composite structure, comprises the inner tube 3, enhancement layer 2 and the outer tube 1 that are bonded together by hot melting way from the inside to the outside.The inside nominal diameter of composite pipe is DN200～DN300.Inner tube 3 and enhancement layer 2 or enhancement layer 2, together with being bonded and fixed at after outer tube 1 is by infrared rays or microwave heating melting, to eliminate the gap between each layer, make body become an adhered overall structure.
In process of production, inner tube 3 by PE or PE-RT material through interior pipe mold extruding and moulding, be mainly used in transmission medium, enhancement layer 2 is mainly used in bearing interior pressure, enhancement layer 2 has four layers at least, every one deck comprises at least four reinforcing bands, and the reinforcing band of every one deck is all coated in inner tube 3 according to fixing helix angle in opposite direction.Outer tube 1 is extruded and is coated on outside enhancement layer 2 through outer tube die, finally bonds together by the mode of infrared or microwave heating, forms an entirety.Wherein, reinforcing band forms (see figure 4) by the reinforcing fiber 21 of one group of alinement and the polyolefine material 22 being wrapped in outside reinforcing fiber 21, wherein the reinforcing band of first layer is wrapped according to certain spiral angle on the outer wall of inner tube 3, the reinforcing band of the second layer is wrapped on first layer reinforcing band according to certain spiral angle, the 3rd layer of reinforcing band is wound in outside second layer reinforcing band by helix angle, and the 4th layer is wound in outside the 3rd layer of reinforcing band according to helix angle.The reinforcing band of above-mentioned adjacent two layers is bonded and fixed at together after by infrared rays or microwave heating melting.
In the present embodiment, can, according to the different inner tube 3 of the different choice of transmission medium, according to different working pressures, select different enhancement layers 2 materials, to reduce client's user cost.Heavy caliber thermoplastic composite plastic tube road not only can overcome the deficiency that steel pipe and common PE pipe in use exist like this, can also meet the demand of the pipelines such as client is large to bore, pressure is high, corrosion-resistant.
Embodiment two
The present embodiment and embodiment's one difference is: the inside nominal diameter of composite pipe is DN300, is the thermoplasticity reinforced composite pipe of the current maximum caliber occurring.
Embodiment three
The difference of the present embodiment is: the inside nominal diameter of composite pipe is DN250.
Embodiment four
The difference of the present embodiment is: the inside nominal diameter of composite pipe is DN200.
In addition to the implementation, the utility model also can have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
