The fields such as communication.High density polyethylene (HDPE) (HDPE) be white powder or granular product it is nontoxic, it is tasteless, crystallinity be 80%~
90%, softening point is 125~l35 DEG C, using temperature up to 100 DEG C；Hardness, tensile strength and creep properties are better than low density polyethylene
Alkene；Wearability, electrical insulating property, toughness and cold resistance are preferable；Chemical stability is good, at room temperature, insoluble in any organic
Solvent, the corrosion of acid and alkali resistance and various salts.
HDPE is inflammable, can burn away from after fire, bad mechanical property, and easily-deformable, easy to aging, easy embrittlement, surface hardness is low,
Easily scratch.
Utility model content
The utility model provides that a kind of fire protecting performance is good, intensity is high and corrosion resistant HDPE power pipe.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of HDPE power pipe, including external tube layer and interior tube layer, said inner tube layer are socketed in external tube layer, the external tube layer
It is made of HDPE material, is embedded with cushioning material between the external tube layer and interior tube layer, said inner tube layer is from the inside to the outside successively
It equipped with insulating layer and fireprotection layer, is equipped in the insulating layer and is used for metal foil shielded layer, the external tube layer is successively set from the inside to the outside
There are corrosion-resistant material layer, wearing layer and anti-flaming dope layer, wherein corrosion-resistant material layer and wearing layer consistency of thickness, the power pipe
Inside is equipped with support member, and the inner wall of the support member and power pipe is detachably connected, and the support member includes at least two
