Abstract
The utility model discloses a trenchless polyethylene (PE) pipe, which comprises a plurality of sections of connected pipes; and a binding tape layer is bound at the connection part of the pipes by rubber and plastics. The trenchless PE pipe of the utility model has the advantages of excellent high tenacity, flexibility, corrosion resistance, fast splitting resistance, easy recovery, long service life and low possibility of leakage, thereby being suitable for trenchless PE pipes with the temperature less than 40 degrees in the fields of water supply, drainage, chemical engineering, metallurgy, mine and the like.
Description
Technical field
The utility model relates to a kind of pipeline, and particularly a kind of temperature that is applicable to is no more than the non-excavation PE pipeline in fields such as 40 ℃ municipal water supply, draining, metallurgy, mine.
Background technique
In fields such as municipal water supply, draining, metallurgy, mines, often pipe temperature is no more than 40 ℃, thereby require also that its pipeline is light to be easy to transportation, also have simultaneously cracking resistance, anticorrosive, characteristics such as the life-span is grown, do not reveal, yet prior art really often can not be taken into account these characteristics.
Summary of the invention
In order to address the above problem, the utility model provides a kind of non-excavation PE pipeline, and its high tenacity, flexible, long lifetime, anticorrosive and good seal is applicable to that temperature is no more than fields such as 40 ℃ municipal water supply, draining, chemical industry, metallurgy, mine.
A kind of non-excavation PE pipeline comprises plural number joint connecting tube, it is characterized in that described jointing is pricked one deck band with rubber plastic.
Described pipeline can be coiled, and its single-unit length can be regulated arbitrarily;
Described pipeline ring tube wall adopts polyethylene (PE) solid wall pipe material;
Connection between the described pipeline adopts hot melt to connect or electric smelting connects.
The beneficial effect of the utility model generation is: have good high tenacity, flexible, corrosion-resistant, anti-quick fragility, easily recovery, long, the difficult advantage of revealing of life-span.
Description of drawings
Fig. 1 is a jointing sectional view of the present utility model;
Fig. 2 is a hot melt connection diagram of the present utility model;
Fig. 3 is an electric smelting connection diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.Be illustrated in figure 1 as jointing sectional view of the present utility model, its pipeline 1 jointing is pricked one deck band 2 with rubber plastic, the ring tube wall of pipeline 1 adopts polyethylene (PE) solid wall pipe material, its flexible polyethylene pipe that makes can be coiled, with long length supply, avoided a large amount of joint and pipe fittings, increased the economic value of this material pipe engineering.
Fig. 2 is the hot melt connection diagram, the connection end face of pipeline 1 is cleaned and cuts and mill, place on the welding machine anchor clamps and clamping, alignment two interfacing parts, make its end surface dislocation amount be not more than 10% of wall thickness, put into 200～210 ℃ of heating plate 3 heating then, heating plate 3 is taken out in the back that finishes, engage two heating surfaces rapidly, boost to welding pressure and pressurize cooling.
Fig. 3 is the electric smelting connection diagram, and cleanser conduit 1 connects end face, marks insertion depth, and electric melting pipe fittings 4 is enclosed within on the pipeline 1, and alignment connecting tube 1 guarantees it on same straight line, 5 heating of energising electric heating wire.During cooling, must not move the pipeline 1 of connection or it is applied any external force.
After pipeline 1 connects the cooling end, prick one deck band 2 with rubber plastic at its position at jointing, increase the sealing of joint.
Claims (4)
1. a non-excavation PE pipeline comprises plural number joint connecting tube, it is characterized in that described jointing is pricked one deck band with rubber plastic.
2. non-excavation PE pipeline as claimed in claim 1 is characterized in that described pipeline can be coiled, and its single-unit length can be regulated arbitrarily.
3. non-excavation PE pipeline as claimed in claim 1 is characterized in that, described pipeline ring tube wall adopts PE solid wall pipe material.
