Abstract

The utility model discloses a HBPE filling station pipe, including inner tube and outer tube, outer bore of pipe is greater than the external diameter of inner tube makes the inner wall of outer tube with the clearance has between the outer wall of inner tube, be provided with the strengthening rib on the inner wall of outer tube, the top of strengthening rib with the clearance has between the outer wall of inner tube, the inner tube is for following the interior extremely outer five -layer co -extrusion tubular product that hinders oxygen layer, EVA high score sublayer, PE layer in proper order for PE layer, EVA high score sublayer, EVOH. The utility model discloses a set up the double tube of inner tube and outer tube, the outer tube plays the effect of protection to the inner tube, prevents that outside sharp -pointed object is hindered to the inner tube to lead to the fact revealing of in inner tube oil, and is gapped between outer tube and the inner tube in addition, can be used for placing monitoring devices, just in case the oil is revealed in the inner tube, can arrive the clearance between outer tube and the inner tube, is monitored warning by monitoring devices, is in time handled, is unlikely to to pollute soil, leads to the fact environmental pollution, resistance to corrosion and antiseep nature have greatly been improved.

Description

A kind of HBPE gas station pipe

Technical field

This utility model relates to tubing field, particularly relates to a kind of HBPE gas station pipe.

Background technology

In today that industry is flourishing, oil is inseparable with people, the operating of various machineries, automobile operation etc. all Be unableing to do without oil, gas station also spreads all over the world, with the life being convenient for people to.But oil has great contaminative, especially transports Can cause the most serious environmental pollution with generation leakage during transmission, this seems the heaviest in the transfer conduit of gas station Want, be embedded in underground due to transfer conduit for a long time, corroded by fluid and external humidification soil, leakage phenomenon often occurs, causes Soil pollution.

So, now it is badly in need of the tubing of a kind of anticorrosion, antiseep, the transmission of oil in gas station.

Utility model content

The purpose of this utility model is to provide a kind of HBPE gas station pipe, solves that existing OCTG is perishable, easy to leak Problem.

For solving above-mentioned technical problem, this utility model adopts the following technical scheme that

This utility model one HBPE gas station manages, including inner and outer tubes；The internal diameter of described outer tube is more than said inner tube External diameter, make, between inwall and the outer wall of said inner tube of described outer tube, there is gap；It is provided with on the inwall of described outer tube and adds Strong muscle, has gap between top and the outer wall of said inner tube of described reinforcement;

Said inner tube is HBPE pipe；Described HBPE pipe for being followed successively by PE layer from the inside to the outside, EVA macromolecule layer, EVOH hinder oxygen Layer, the five-layer co-squeezing tubing of EVA macromolecule layer, PE layer.

Further, described reinforcement is along the axial linear type of described outer tube wall, multiple reinforcement uniform intervals cloth Put on the inner peripheral surface of outer tube.

Further, described reinforcement is rounded along described outer tube wall, and multiple reinforcements are along outer tube wall axially etc. Spacing is arranged.

Further, described reinforcement is along described outer tube wall twist.

Further, said inner tube and outer coaxial tube are arranged.

Further, described reinforcement top is 1-2mm to the distance of said inner tube outer wall.

Further, the height of described reinforcement is 1-2mm.

Further, the material of described outer tube is PE.

Compared with prior art, Advantageous Effects of the present utility model is as follows:

This utility model is by arranging the bimetallic tube of inner and outer tubes, and inner tube is played the effect of protection by outer tube, outside preventing The sharp-pointed object in portion hurts inner tube and causes the leakage of oil product in inner tube, additionally has gap between outer tube and inner tube, can be used to put Putting monitoring device, just in case oil product is revealed in inner tube, can arrive in the gap between outer tube and inner tube, monitored device monitoring is to also Report to the police, processed in time, be unlikely to contaminated soil, cause environmental pollution；Drastically increase anticorrosive property and leakproof.

Detailed description of the invention

As shown in Figure 1, 2, a kind of HBPE gas station pipe, including inner tube 1 and outer tube 2；The internal diameter of described outer tube 2 is more than described The external diameter of inner tube 1, makes have gap between inwall and the outer wall of said inner tube 1 of described outer tube 2；Inner tube is played by first outer tube The effect of protection, prevents outside sharp-pointed object from hurting inner tube and causes the leakage of oil product in inner tube；Again between outer tube and inner tube There is gap, can be used to place monitoring device, just in case oil product is revealed in inner tube, can arrive in the gap between outer tube and inner tube, Monitored device monitoring to and report to the police, processed in time, be unlikely to contaminated soil, caused environmental pollution.Described outer tube 2 interior It is provided with reinforcement 3 on wall, between top and the outer wall of said inner tube 1 of described reinforcement 3, there is gap, on the one hand reinforcement Enhance the structural strength of outer tube, on the other hand ensure that the outer wall of inner tube will not be with the contact internal walls of outer tube, even if due to gravity Etc. factor, inner tube is the most coaxial with outer tube, also can guarantee that certain gap.

The material of described outer tube 2 is PE, waterproof, moistureproof.Said inner tube 1 is managed for HBPE；Described HBPE pipe is for from the inside to the outside Being followed successively by the five-layer co-squeezing tubing of PE layer, EVA macromolecule layer, EVOH oxidation prevention layer, EVA macromolecule layer, PE layer, leakproof is strong.

The present embodiment, specifically said inner tube 1 and outer tube 2 are coaxially disposed, outside described reinforcement 3 top to said inner tube 1 The distance of wall is 1.5mm, and the height of described reinforcement 3 is 1.5mm.

As it is shown on figure 3, the first specific embodiment, other features are same as described above, do not repeat them here, described reinforcement 3 is that multiple reinforcement 3 uniform intervals are arranged on the inner peripheral surface of outer tube 2 along the axial linear type of described outer tube 2 inwall.

As shown in Figure 4, the second specific embodiment, other features are same as described above, do not repeat them here, described reinforcement 3 is rounded along described outer tube 2 inwall, and multiple reinforcements 3 are axially equally spaced along outer tube 2 inwall.

As it is shown in figure 5, the third specific embodiment, other features are same as described above, do not repeat them here, described reinforcement 3 along described outer tube 2 inwall twist.

Embodiment described above is only to be described optimal way of the present utility model, not to of the present utility model Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are new to this practicality Various deformation that the technical scheme of type is made and improvement, all should fall into the protection domain that this utility model claims determine In.
