Abstract
The utility model discloses a high performance HDPE double -walled corrugated pipe, including the level and smooth inner wall pipe and the outer wall pipe of corrugate, inner wall pipe and outer wall pipe be the HDPE pipe, the outside of outer wall pipe is equipped with the protective layer, the protective layer is the quartz sand grained layer, the inboard of inner wall pipe be equipped with corrosion -resistant layer, corrosion resistant coating includes from the interior butadiene acrylonitrile rubber layer that outwards sets gradually, fluorubber layer and chloroprene rubber layer, the utility model has the advantages of: strengthened whole compressive strength, elasticity is big moreover, and the crookedness is high, has improved the rigidity and the compression strength of product, and the wearability is good, difficult wearing and tearing, and corrosion effects is good, has prolonged life.
Description
Technical field
The utility model relates to a kind of bellows, and specifically a kind of high-performance HDPE double-wall corrugated pipe, belongs to bellows field.
Background technique
Polyethylene pipe applied range, from the heavy wall clarinet being used for industry and urban duct for the yellow pipe of rock gas small bore to 48in diameter.The rainwater drainage pipe that diameter hollow wall is effective to be made as concrete and the substitute rapid development of other sewerage pipeline.There is excellent resistance to great majority life and the characteristic of chemicals for industrial use.The chemical product of some kind can produce chemical corrosion, such as corrosive oxidation agent (red fuming nitric acid (RFNA)), aromatic hydrocarbon (dimethylbenzene) and halogenated hydrocarbon (carbon tetrachloride).Have good electrical property, particularly dielectric strength is high, makes it be applicable to electric wire very much.In to high molecular weight grades, there is fabulous impact resistance, even all like this under-40F low temperature at normal temperature.Polyethylene (polyethylene is called for short PE) is that ethene is through being polymerized obtained a kind of thermoplastic resin.Industrially, the copolymer of ethene and a small amount of alpha-olefin is also comprised.Polyethylene odorless, nontoxic, feel ceraceous, has excellent resistance to low temperature, and chemical stability is good, the erosion of the most of soda acid of ability.Be insoluble to common solvent under normal temperature, moisture absorption is little, and electrical insulation capability is excellent.At present, double-wall corrugated pipe is applied to the association areas such as building, communication, agricultural just more and more with the performance of its excellence, and in use, intensity is low for the double-wall corrugated pipe of prior art, and easy to wear, and anticorrosion effect is poor, and working life is short.
Model utility content
In order to solve the problem, the utility model devises a kind of high-performance HDPE double-wall corrugated pipe, enhance entire compression intensity, and elasticity is large, tortuosity is high, and improve rigidity and the compressive strength of product, wear resistance is good, not easy to wear, anticorrosion effect is good, extends working life.
The technical solution of the utility model is:
A kind of high-performance HDPE double-wall corrugated pipe, comprise level and smooth inner wall tube and undulatory outer wall pipe, described inner wall tube and outer wall pipe are HDPE pipe, the outside of described outer wall pipe is provided with protective layer, and described protective layer is quartz sand particle layer, and quartz sand particle sticks on skin, form one deck quartz sand particle layer, improve rigidity and the compressive strength of product, wear resistance is good, not easy to wear; The inner side of described inner wall tube is provided with anti-corrosion layer, and described corrosion-resistant finishes comprises the nitrile butadiene rubber layer, fluororubber layer and the neoprene layer that from inside to outside set gradually, and anticorrosion effect is good.
Further, the outside of described protective layer is also provided with PIC coating, thus makes product have good anti-wear effect, and antiwear property is excellent.
Further, be connected between described inner wall tube and outer wall pipe by rubber ring, not only inside and outside two-layer tube wall combines firmly, enhances entire compression intensity, and elasticity is large, and tortuosity is high.
Further, the space between described inner wall tube and outer wall pipe is also filled with thermal insulation layer, and described thermal insulation layer is asbestos, and asbestos have good thermal insulation, is good thermal insulating material.
The utility model has the advantage of: enhance entire compression intensity, and elasticity is large, tortuosity is high, improves rigidity and the compressive strength of product, and wear resistance is good, and not easy to wear, anticorrosion effect is good, extends working life.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
