Abstract
The utility model discloses using high-pressure composite pipe, including from-inner-to-outer set gradually PVC M layer, centre enhancement layer, outer layer pvc pipe under mine, the main points of its technical scheme are：Fixed using melt viscosity fixed between described PVC M layers and middle enhancement layer, middle enhancement layer and outer layer pvc pipe, the PVC M thickness degree is 3 20mm.The utility model provides a kind of high-pressure composite pipe, using less thickness, and with intensity higher, rigidity and impact resistance.
Description
【Technical field】
The utility model is related to use high-pressure composite pipe under mine.
【Background technology】
Multiple tube is mainly used in oil-gas gathering and transportation, water filling and note alcohol.Now, thermoplastic composite plastic tube is (such as conventional PVC-
M, i.e. polyvinyl chloride pipe) application field include ocean flexible pipe, hot spring delivery pipe, oil, product oil, natural gas transportation,
Municipal plumbing, oily water, desalinization, mine water supply, air feed, draining, coal washing water, coal dust conveying, chemical plant, steel mill's corrosion
Property liquid conveying, but intensity is small in use, and pressure-bearing is low, and certain threat is caused to safety in production.
【The content of the invention】
The utility model purpose is to overcome deficiency of the prior art, there is provided a kind of high-pressure composite pipe, using less thickness
Degree, and with intensity higher, rigidity and impact resistance.
The utility model is achieved through the following technical solutions：
High-pressure composite pipe, including from-inner-to-outer set gradually PVC-M layer, centre enhancement layer, outer layer PVC are used under mine
Pipe, it is characterised in that：Between described PVC-M layers and middle enhancement layer, middle enhancement layer and outer layer pvc pipe, PUR adhesion is used
Fixed, the PVC-M thickness degree is 3-20mm.
Preferably, the middle enhancement layer is basalt fibre.
Preferably, the middle enhancement layer is glass fibre.
Preferably, the middle enhancement layer is steel wire.
Preferably, the middle enhancement layer thickness is 2-5mm.
Preferably, the middle enhancement layer thickness is 4mm.
Preferably, the outer layer pvc pipe thickness is 3-20mm.
Compared with prior art, the utility model has the following advantages：
High-pressure composite pipe of the present utility model, is made compound tube, it is to avoid because of list under positive pressure using multilayer fitting method
The defect that the material outside destruction of layer wall thickness can not make full use of, compared with equal wall thickness tubing, it has smaller thickness, and has
Intensity higher, rigidity and impact resistance, the pipe has lightweight advantage, easy for installation, corrosion-resistant, tubing service life
It is long, especially colliery water supply and sewage is needed, 4MPa is reached using pressure, burst pressure reaches 12Mpa.
【Brief description of the drawings】
Fig. 1 is the utility model structural representation.
【Specific embodiment】
High-pressure composite pipe, including from-inner-to-outer set gradually PVC-M layer 1, centre enhancement layer 2, outer layer PVC are used under mine
Pipe 3, between described PVC-M layers 1 and middle enhancement layer 2, middle enhancement layer 2 and outer layer pvc pipe 3, is fixed using the adhesion of PUR 4,
The PVC-M thickness degree is 3-20mm.Compared to existing multiple tube, there is smaller product wall thickness with this product, set in structure
On meter more rationally, PVC-M layers of internal layer combines middle enhancement layer pressure-bearing, and the layer of PVC of outer layer is corrosion-resistant, in the case of being combined
Certain deformation can be still born, and can the long-term work under 4MPa high-pressure situations.
The middle enhancement layer 2 is basalt fibre.Enhancement layer is basalt fibre in the middle of preferred, in heat-insulated, antifriction
Wiping the aspects such as deformation has significant advantage.
The middle enhancement layer 2 is glass fibre.Enhancement layer is glass fibre in the middle of preferred, can further strengthen multiple
The intensity of pipe is closed, and remains to maintain lighter weight.
The middle enhancement layer 2 is steel wire.Enhancement layer is steel wire in the middle of preferred, can further strengthen the tough of multiple tube
Property and intensity.
The thickness of middle enhancement layer 2 is 2-5mm.Middle enhancement layer is bonded with PUR respectively with internal layer and outer layer,
160-190 DEG C of hot melting cohesion, the middle enhancement layer with this product need to only maintain less thickness, can meet wanting for anti-high pressure
Ask, preferred middle enhancement layer thickness is 2-5mm.
The thickness of middle enhancement layer 2 is 4mm.Enhancement layer thickness is 4mm in the middle of preferred.
The thickness of outer layer layer of PVC 3 is 3-20mm.Preferred outer layer layer of PVC thickness is 3-20mm, and preferred thickness is
12mm, possesses the outer tube diameter specification of general pvc pipe, is easy to assembling to use.
