Abstract
The utility model discloses a large-caliber composite metal hose. The large-caliber composite metal hose comprises a metal hose body which is the main body of the large-caliber composite metal hose, a flange, and a poly tetra fluoro ethylene lining attached to the inner surface of the metal hose body. The poly tetra fluoro ethylene lining is formed by compositing a poly tetra fluoro ethylene liner plate and a poly tetra fluoro ethylene film. The large-caliber composite metal hose is characterized in that the thickness of the poly tetra fluoro ethylene liner plate is 0.2-0.6mm, and the thickness of the poly tetra fluoro ethylene film is 2-3mm. According to the large-caliber composite metal hose, the density and the ductility of the poly tetra fluoro ethylene lining can be improved remarkably, and the corrosion resistance of the metal hose can be guaranteed.
Description
Technical field
The utility model relates to a kind of composite metal hose, is specifically related to a kind of heavy caliber composite metal hose.
Background technique
Metallic hose is the needs that require for corrosion resistance of caliber metal flexible pipe particularly, at the internal surface applying tetrafluoro liner of metallic hose.The metallic hose of prior art particularly caliber metal flexible pipe tetrafluoro liner is that after being wound around by polytetrafluoroethylene film, sintering forms.This metallic hose exists lower column defects: the tetrafluoro liner density that after being wound around by polytetrafluoroethylene film, sintering forms is low, extends rate variance, and crackle is easily arranged, and affects the corrosion resistance of metallic hose.
Summary of the invention
The utility model provides a kind of and can significantly improve tetrafluoro liner density and specific elongation for the deficiencies in the prior art, guarantees the heavy caliber composite metal hose of the corrosion resistance of metallic hose.
The utility model is achieved through the following technical solutions technical goal.
The heavy caliber composite metal hose, it comprises metallic hose, the flange that consists of its main body, the tetrafluoro liner that is fitted in the metallic hose internal surface; Its improvements are: described tetrafluoro liner is composited by tetrafluoro liner plate and polytetrafluoroethylene film.
Further improve and be: the thickness of described tetrafluoro liner plate is 0.2～0.6mm.
Further improve and be: the thickness of described polytetrafluoroethylene film is 2～3mm.
The utility model compared with prior art, have following good effect: the tetrafluoro liner is composited by tetrafluoro liner plate and polytetrafluoroethylene film, can significantly improve tetrafluoro liner density and specific elongation like this, having solved the tetrafluoro liner that after in the prior art, polytetrafluoroethylene film is wound around, sintering forms easily has crackle, affects the problem of metallic hose corrosion resistance.
