Abstract
The invention discloses a high-flexibility composite tube. The high-flexibility composite tube comprises an inner plastic tube, a reinforced steel tube and an outer plastic tube which are sequentially in sleeve joint, wherein spirally distributed strengthening ribs are arranged on the wall of the reinforced steel tube and protrude toward two sides of the inner surface and the outer surface of the wall of the reinforced steel tube; protrusion peaks on the same side are positioned on the same straight line which is parallel to the central axis of the composite tube; a first hot melt adhesive layer is arranged between the inner plastic tube and the reinforced steel tube; a second hot melt adhesive layer is arranged between the reinforced steel tube and the outer plastic tube; the length direction of the composite tube is used as an axis X, the radial direction of the composite tube is used as an axis Y, the connection line of the protrusion peaks on the adjacent same sides of the strengthening ribs is a quadratic function using y as a dependent variable and x as an independent variable, and the inner plastic tube and the outer plastic tube are both made from crosslinked polyethylene. The high-flexibility composite tube disclosed by the invention is good in pressure resistance and excellent in bending property.
Description
Technical field
The present invention relates to body equipment technology field, relate in particular to a kind of high flexibility composite pipe.
Background technique
Current, because various composite pipes have good usability and the feature such as quick and easy for installation, be widely used in industry, agricultural and life each field as conveyance conduit.Water inlet, waste pipe, electric wire protective tube etc. often adopt composite pipe.In prior art, it is compound that composite pipe often adopts metal tube and plastic tube to carry out, and utilizes metal tube to improve good intensity, and utilize plastic tube to make composite pipe have lower weight.In the time that in composite pipe, metal tube is thinner, often make the anti-pressure ability of composite pipe lower, and metal tube is when thicker, makes the bending properties deficiency of composite pipe, therefore, the anti-pressure ability of composite pipe and bending properties cannot well be taken into account, and need improve.
Summary of the invention
In order to solve the technical problem existing in background technique, the present invention proposes a kind of high flexibility composite pipe, its anti-pressure ability is good and bending properties is excellent.
A kind of high flexibility composite pipe that the present invention proposes, plastic inner pipe, reinforcement steel pipe and plastic outer tube, plastic inner pipe, reinforcement steel pipe, plastic outer tube are socketed successively, the tube wall of strengthening steel pipe has the stiffening rib of spiral distribution, stiffening rib is to inner surface of tube wall and the outer surface both sides projection of strengthening steel pipe, the summit of homonymy projection be located along the same line and this straight line parallel with composite pipe central axis, between plastic inner pipe and reinforcement steel pipe, there is the first heat-fusing glue layer, strengthen thering is the second heat-fusing glue layer between steel pipe and plastic outer tube; Taking composite pipe length direction as X-axis, taking composite pipe radially as Y-axis, between the adjacent homonymy of stiffening rib projection summit line for taking y as dependent variable, the quadratic function that x is independent variable, wherein, plastic inner pipe and plastic outer tube all adopt crosslinked polyethylene to make.
Preferably, the spacing between the adjacent homonymy projection of stiffening rib summit and the external diameter ratio of plastic outer tube are 0.05-0.3.
Preferably, the spacing between the adjacent homonymy projection of stiffening rib summit and the ratio of height of projection are 0.3-0.6.
In above-mentioned high flexibility composite pipe, the plastic inner pipe that is positioned at internal layer can make composite pipe inwall have smooth surface, thereby in the time carrying for liquid, there is less flow resistance, being positioned at outer field plastic outer tube can make composite pipe have good anti-extrusion ability, to the stiffening rib with spiral distribution be set on the tube wall of reinforcement steel pipe, can make to strengthen steel pipe provides on good intensity basis for composite pipe, there is good pliability, simultaneously, because all adopting crosslinked polyethylene, plastic inner pipe and plastic outer tube make, can make composite pipe obtain on good anti-pressure ability basis, crooking ability is strong, reinforcing rib structure is designed to taking composite pipe length direction as X-axis, taking composite pipe radially as Y-axis, between the adjacent homonymy projection of stiffening rib summit, line is that the quadratic function that x is independent variable, can ensure that stiffening rib obtains good bending properties and mechanical strength taking y as dependent variable, between plastic inner pipe and reinforcement steel pipe, there is the first heat-fusing glue layer, strengthen thering is the second heat-fusing glue layer between steel pipe and plastic outer tube, make the combination between plastic inner pipe, reinforcement steel pipe, plastic outer tube good, be difficult for producing slip, depart from.
Brief description of the drawings
