Description
Technical field
The utility model belongs to pipeline field, and in particular to be a kind of high-toughness wear-resistant PE pipe.
Background technology
PE pipes have medium density polyethylene pipe and high density polyethylene pipe.SDR11 and SDR17.6 series is divided into according to wall thickness.
The former is suitable for conveying gaseous artificial coal gas, natural gas, liquefied petroleum gas, and the latter is mainly for delivery of natural gas.And steel pipe
Compare, construction technology is simple, there is certain pliability, more important is preservative treatment is not used as, will save substantial amounts of process.Lack
Point is not so good as steel pipe with regard to apparatus, and the safe spacing of heating power heating is particularly paid attention in construction, and cannot be exposed to air middle-jiao yang, function of the spleen and stomach
Under light, and it is sensitive to chemical substance, prevent the leakage of sewage conduct from damaging, and existing PE pipes produce to reduce
Cost, its instrument strength and chemical property are all not ideal enough, situations such as more serious breakage can occur after long-time service, crack,
Particularly apply in Code in Hazardous Special Locations, due to toughness not enough and can not wide-angle deformation, cause to be merely able to by pipe fitting by two
Duan Guanzi is docked, and not only increases cost, and leakproofness can not ensure.
Utility model content
It in order to solve the above technical problems, the utility model offer toughness is higher, can deform, reduce contact rubbing surface
Product, so that the pipes of the high-toughness wear-resistant PE with higher abrasion resistance.
To achieve the above object, the technical solution adopted in the utility model is a kind of high-toughness wear-resistant PE pipes, including internal layer
Pipe and outer tube, its structural feature are that memory layer is equipped between inner tube and outer tube, and memory layer uses memory alloy of titanium silk system
Into memory alloy of titanium silk outside inner tube, is equipped with the spherical hollow space of dense arrangement in woven mesh in inner layer tube wall, adjacent
Communication channel is equipped between spherical hollow space, the rubber thread of spiral winding is equipped with the outer wall, the surface of rubber thread is by fiber crops
Line braiding winding protection, the outer surface plating matcoveredn of outer tube.
As further improvement of the utility model, the section of outer tube is triangle, and three acute angles of triangle are equipped with
Rounded corner.
As further improvement of the utility model, three planes of outer tube are equipped with arc-shaped concave.
As further improvement of the utility model, the thickness of the protective layer on three rounded corners of outer tube is flat for three
Two times of protective layer thickness on face.
As further improvement of the utility model, the inner surface of inner tube is embedded with inner protective layer, and inner protective layer is rubber
Glue-line.
The beneficial effects of the utility model are：Design is reasonable, simple in structure, can effectively improve wear-resisting property, and
Overall flexibility is improved, there is deformation, can apply in narrow and small tortuous place, reduce unnecessary cost, and
Since integral seamless connects, so sealing performance accesses guarantee.
